Spring WS – Overview

Spring Web Services (Spring-WS) is one of the projects developed by the Spring Community. Its prime focus is to create document-driven Web Services. The Spring Web Services project facilitates contract-first SOAP Service Development, provides multiple ways to create flexible web services, which can manipulate XML payloads in multiple ways.

The Spring web services uses Spring concepts like dependency injection and configurations seamlessly. The Spring-WS requires Spring 3.0 Version. With contract-first development, we start with WSDL Contract and then will use JAVA to implement the required contract.

As opposed to the contract-last approach where JAVA interfaces generate WSDL/XSD contract. The WSDL based contract remains independent of JAVA implementation in the contract-first approach. In case we require changing the JAVA interfaces, then there is no need to communicate the changes made in the existing WSDL contract to the web services users. Spring-WS aims to provide loose coupling between the WSDL contract and its JAVA based implementation.

Features

Following are the features of Spring Web Services −

  • XML Mapping to Objects − XML based requests can be mapped to any object using the information stored in the Message Payload, SOAP Action Header or by using an XPath Expression.

  • Multiple API Support to parse XML − Apart from the standard JAXP APIs (DOM, SAX, StAX) to parse the incoming XML requests, other libraries like JDOM, dom4j, XOM are also supported.

  • Multiple API Support to marshal XML− Spring Web Services supports JAXB 1 and 2, Castor, XMLBeans, JiBX, and XStream libraries using its Object/XML Mapping module. The Object/XML Mapping module can also be used in non-web services code as well.

  • Spring based configurations − Spring Web Services uses the Spring Application Contexts for its configurations having a similar architecture as that of the Spring Web MVC.

  • Integrated WS-Security module − Using the WS-Security module, you can Sign, Encrypt, Decrypt SOAP Messages or Authenticate them.

  • Support for Acegi Security − Using the WS-Security implementation of Spring Web Services, Acegi configuration can be used for your SOAP services.

Architecture

The Spring-WS project consists of five major modules, which are explained below.

  • Spring-WS Core − It is the primary module and provides the Central Interfaces like WebServiceMessage and SoapMessage, the server-side framework, powerful message dispatching capability and support classes to implement Web service endpoints. It also provides Web Service consumer client as WebServiceTemplate.

  • Spring-WS Support − This module provides supports for JMS, emails, etc.

  • Spring-WS Security − This module is responsible to provide WS-Security implementation integrated with core Web Service Module. Using this module, we can add principal tokens, sign, encrypt and decrypt SOAP messages. This module allows using the existing Spring Security Implementation for authentication and authorization.

  • Spring XML − This module provides XML support classes for Spring Web Services. This module is internally used by Spring-WS framework.

  • Spring OXM − This module provides support classes for XML vs Object Mapping.

Spring Web Services Architecture

Spring WS – Environment Setup

In this Chapter, we will understand the process of setting up Spring-WS on Windows and Linux based systems. The Spring-WS can be easily installed and integrated with your current Java environment and MAVEN by following a few simple steps without any complex setup procedures. User administration is required while installation.

System Requirements

The following table lists out the system requirements, while the subsequent steps will guide us through the environment setup procedure.

JDK Java SE 2 JDK 1.5 or above
Memory 1 GB RAM (recommended)
Disk Space No minimum requirement
Operating System Version Windows XP or above, Linux

Let us now proceed with the steps to install Spring-WS.

Step 1: Verify the Java Installation

To begin with, you need to have Java Software Development Kit (SDK) installed on your system. To verify this, execute any of the following two commands depending on the platform you are working on.

If the Java installation has been done properly, then it will display the current version and specification of your Java installation. A sample output is given in the following table.

Platform Command Sample Output
Windows

Open command console and type −

>java -version

Java version “1.7.0_60”

Java (TM) SE Run Time Environment (build 1.7.0_60-b19)

Java Hotspot (TM) 64-bit Server VM (build 24.60-b09,mixed mode)

Linux

Open command terminal and type −

$java -version

java version “1.7.0_25”

Open JDK Runtime Environment (rhel-2.3.10.4.el6_4-x86_64)

Open JDK 64-Bit Server VM (build 23.7-b01, mixed mode)

Step 2: Set your Java Environment

Set the environment variable JAVA_HOME to point to the base directory location where Java is installed on your machine.

S.No. Platform & Description
1

Windows

Set JAVA_HOME to C:ProgramFilesjavajdk1.7.0_60

2

Linux

Export JAVA_HOME=/usr/local/java-current

Append the full path of Java compiler location to the System Path.

S.No. Platform & Description
1

Windows

Append the String “C:Program FilesJavajdk1.7.0_60bin” to the end of the system variable PATH.

2

Linux

Export PATH=$PATH:$JAVA_HOME/bin/

Execute the command java -version from the command prompt as explained above.

Step 3: Download Maven archive

Download Maven 3.3.3 from https://maven.apache.org/download.cgi

OS Archive name
Windows apache-maven-3.3.3-bin.zip
Linux apache-maven-3.3.3-bin.tar.gz
Mac apache-maven-3.3.3-bin.tar.gz

Step 4: Extract the Maven archive

Extract the archive, to the directory you wish to install Maven 3.3.3. The subdirectory apache-maven-3.3.3 will be created from the archive.

OS Location (can be different based on your installation)
Windows C:Program FilesApache Software Foundationapache-maven-3.3.3
Linux /usr/local/apache-maven
Mac /usr/local/apache-maven

Step 5: Set Maven environment variables

Add M2_HOME, M2 and MAVEN_OPTS to the environment variables.

OS Output
Windows

Set the environment variables using system properties.

M2_HOME=C:Program FilesApache Software Foundationapache-maven-3.3.3

M2=%M2_HOME%bin

MAVEN_OPTS=-Xms256m -Xmx512m

Linux

Open command terminal and set environment variables.

export M2_HOME=/usr/local/apache-maven/apache-maven-3.3.3

export M2=$M2_HOME/bin

export MAVEN_OPTS=-Xms256m -Xmx512m

Mac

Open command terminal and set environment variables.

export M2_HOME=/usr/local/apache-maven/apache-maven-3.3.3

export M2=$M2_HOME/bin

export MAVEN_OPTS=-Xms256m -Xmx512m

Step 6: Add Maven bin directory location to the system path

Now append M2 variable to the System Path.

OS Output
Windows Append the string ;%M2% to the end of the system variable, Path.
Linux export PATH=$M2:$PATH
Mac export PATH=$M2:$PATH

Step 7: Verify Maven installation

Now open the console, execute the following mvn command.

OS Task Command
Windows Open Command Console c:> mvn –version
Linux Open Command Terminal $ mvn –version
Mac Open Terminal machine:< joseph$ mvn –version

Finally, verify the output of the above commands, which should be something as shown below −

OS Output
Windows

Java version: 1.7.0_75, vendor: Oracle Corporation

Java home: /Library/Java/Home/jdk1.7.0_75/jre

Step 8: Setup Eclipse IDE

All the examples in this tutorial have been written using the Eclipse IDE. It is recommended that the readers should have the latest version of Eclipse installed on their machine. To install the Eclipse IDE, download the latest Eclipse binaries from the following link https://www.eclipse.org/downloads/. Once the installation is downloaded, unpack the binary distribution into a convenient location.

For example in C:eclipse on windows, or /usr/local/eclipse on Linux/Unix and finally set the PATH variable appropriately. Eclipse can be started by executing the following commands on the windows machine, or you can simply double click on eclipse.exe.

%C:eclipseeclipse.exe

Eclipse can be started by executing the following commands on the UNIX (Solaris, Linux, etc.) machine −

$/usr/local/eclipse/eclipse

After a successful startup, if everything is fine then it should display the following screen −

Eclipse Home page

Step 9: Setup Apache Tomcat

We can download the latest version of Tomcat from https://tomcat.apache.org/. Once the installation is downloaded, unpack the binary distribution into a convenient location. For example in the C:apache-tomcat-7.0.59 on a windows machine, or in the /usr/local/apache-tomcat-7.0.59 on a Linux/Unix machine and then set the CATALINA_HOME environment variable pointing to the installation locations.

Tomcat can be started by executing the following commands on a windows machine, or you can simply double click on startup.bat

%CATALINA_HOME%binstartup.bat
 
or
 
C:apache-tomcat-7.0.59binstartup.bat

Tomcat can be started by executing the following commands on UNIX (Solaris, Linux, etc.) machine −

$CATALINA_HOME/bin/startup.sh
 
or
 
/usr/local/apache-tomcat-7.0.59/bin/startup.sh

After a successful startup, the default web applications included with Tomcat will be available by visiting – http://localhost:8080/. If everything is ok, then it should display the following screen −

Tomcat

Further information about configuring and running Tomcat can be found in the documentation included here, as well as on the Tomcat website − https://tomcat.apache.org

Tomcat can be stopped by executing the following commands on a windows machine −

%CATALINA_HOME%binshutdown

or

C:apache-tomcat-7.0.59binshutdown

Tomcat can be stopped by executing the following commands on the UNIX (Solaris, Linux, etc.) machine −

$CATALINA_HOME/bin/shutdown.sh

or

/usr/local/apache-tomcat-7.0.59/bin/shutdown.sh

Once we are done with this last step, we are ready to proceed for the first Web Services Example, which we will discuss in the next chapter.

Spring WS – First Application

Let us start writing an actual SOAP based web service with Spring-WS Framework. Before we start writing our first example using the Spring-WS framework, we have to ensure that the Spring-WS environment is setup properly as explained in Spring Web Services – Environment Setup chapter. We are assuming that the readers have some basic working knowledge with the Eclipse IDE.

Therefore, let us proceed to write a simple Spring WS Application which will expose a web service method to book a leave in an HR Portal.

Contract-first Approach

Spring-WS uses the Contract-first approach, which means we should have our XML Structures ready before writing any JAVA based implementation code. We are defining a LeaveRequest Object, which has sub-objects – Leave and Employee.

Following are the required XML constructs −

Leave.xml

<Leave xmlns = "http://tutorialspoint.com/hr/schemas">
   <StartDate>2016-07-03</StartDate>
   <EndDate>2016-07-07</EndDate>
</Leave>

Employee.xml

<Employee xmlns = "http://tutorialspoint.com/hr/schemas">
   <Number>404</Number>
   <FirstName>Mahesh</FirstName>
   <LastName>Parashar</LastName>
</Employee>

LeaveRequest.xml

<LeaveRequest xmlns = "http://tutorialspoint.com/hr/schemas">
   <Leave>
      <StartDate>2016-07-03</StartDate>
      <EndDate>2016-07-07</EndDate>
   </Leave>
   
   <Employee>
      <Number>404</Number>
      <FirstName>Mahesh</FirstName>
      <LastName>Parashar</LastName>
   </Employee>
</LeaveRequest>

hr.xsd

<xs:schema xmlns:xs = "http://www.w3.org/2001/XMLSchema"
   xmlns:hr = "http://tutorialspoint.com/hr/schemas"
   elementFormDefault = "qualified"
   targetNamespace = "http://tutorialspoint.com/hr/schemas">
   
   <xs:element name = "LeaveRequest">
      <xs:complexType>
         <xs:all>
            <xs:element name = "Leave" type = "hr:LeaveType"/>
            <xs:element name = "Employee" type = "hr:EmployeeType"/>
         </xs:all>
      </xs:complexType>
   </xs:element>
   
   <xs:complexType name = "LeaveType">
      <xs:sequence>
         <xs:element name = "StartDate" type = "xs:date"/>
         <xs:element name = "EndDate" type = "xs:date"/>
      </xs:sequence>
   </xs:complexType>
   
   <xs:complexType name = "EmployeeType">
      <xs:sequence>
         <xs:element name = "Number" type = "xs:integer"/>
         <xs:element name = "FirstName" type = "xs:string"/>
         <xs:element name = "LastName" type = "xs:string"/>
      </xs:sequence>
   </xs:complexType>
</xs:schema>

Create the Project

Let us now open a command console, go the C:MVN directory and execute the following mvn command.

C:MVN>mvn archetype:generate -DarchetypeGroupId = org.springframework.ws
-DarchetypeArtifactId = spring-ws-archetype -DgroupId = com.tutorialspoint.hr
-DartifactId = leaveService

Maven will start processing and will create the complete Java Application Project Structure.

Now go to C:/MVN directory. We will see a java application project created named leaveService (as specified in artifactId). Update the pom.xml and add HumanResourceService.java and HumanResourceServiceImpl.java in the following folder – C:MVNleaveServicesrcmainjavacomtutorialspointhrservice folder. Once that is done, then add LeaveEndpoint.java in the following folder – C:MVNleaveServicesrcmainjavacomtutorialspointhrws folder.

Start the Tomcat server and ensure we are able to access other webpages from the webapps folder using a standard browser. Try to access the URL – http://localhost:8080/leaveService/leave.wsdl, if everything is ok with the Spring Web Application, we should see the following screen.

Spring WS – Static WSDL

In the previous chapter Spring -WS – First Application, we have generated WSDL automatically using the Spring WS Configuration. In this case, we will display how to expose the existing WSDL using the Spring WS.

Step Description
1 Create a project with a name leaveService under a package com.tutorialspoint as explained in the Spring WS – First Application chapter.
2 Create a WSDL leave.wsdl under the /WEB-INF/wsdl sub-folder.
3 Update spring-ws-servlet.xml under the /WEB-INF sub-folder. We are using the static-wsdl tag here instead of the dynamic-wsdl.
4 The final step is to create content of all source and configuration files and export the application as explained below.

/WEB-INF/spring-ws-servlet.xml

Spring WS – Writing Server

In this chapter, we will understand how to create a web application server using Spring WS.

Step Description
1 Create a project with a name countryService under a package com.tutorialspoint as explained in the Spring WS – First Application chapter.
2 Create countries.xsd, domain classes, CountryRepository and CountryEndPoint as explained in the following steps.
3 Update spring-ws-servlet.xml under the /WEB-INF sub-folder.
4 The final step is to create content for all the source and configuration files and export the application as explained below.

countries.xsd

         <xs:enumeration value = "INR"/>
      </xs:restriction>
   </xs:simpleType>
</xs:schema>

Create the Project

Let us open the command console, go the C:MVN directory and execute the following mvn command.

C:MVN>mvn archetype:generate -DarchetypeGroupId = org.springframework.ws 
-DarchetypeArtifactId = spring-ws-archetype -DgroupId = com.tutorialspoint 
-DartifactId = countryService

Maven will start processing and will create the complete Java Application Project Structure.

Run the Project

Once we have created the source and configuration files, export the countryService.war file in Tomcat”s webapps folder.

Now, start the Tomcat server and ensure if we can access other webpages from the webapps folder using a standard browser. Make a POST request to the URL – http://localhost:8080/countryService/ and by using any SOAP client make the following request.

<x:Envelope xmlns:x = "http://schemas.xmlsoap.org/soap/envelope/" 
   xmlns:tns = "http://tutorialspoint/schemas">
   <x:Header/>
   <x:Body>
      <tns:getCountryRequest>
         <tns:name>United States</tns:name>
      </tns:getCountryRequest>
   </x:Body>
</x:Envelope>

You will see the following result.

<SOAP-ENV:Envelope xmlns:SOAP-ENV = "http://schemas.xmlsoap.org/soap/envelope/">
   <SOAP-ENV:Header/>
   <SOAP-ENV:Body>
      <ns2:getCountryResponse xmlns:ns2 = "http://tutorialspoint/schemas">

Spring WS – Unit Test Server

In this chapter, we will understand how to unit test a web application service created by using the Spring WS.

Step Description
1 Update project countryService created in the Spring WS – Write Server chapter. Add src/test/java folder.
2 Create CustomerEndPointTest.java under the – src/test/java/com/tutorialspoint/ws folder and then update the POM.xml as detailed below.
3 Add spring-context.xml under the src/main/resources sub-folder.
4 The final step is to create content for all the source and configuration files and test the application as explained below.

Spring WS – Writing Client

In this chapter, we will learn how to create a client for the web application server created in the Spring WS – Writing Server using Spring WS.

Step Description
1 Update the project countryService under the package com.tutorialspoint as explained in the Spring WS – Writing Server chapter.
2 Create CountryServiceClient.java under the package com.tutorialspoint.client and MainApp.java under the package com.tutorialspoint as explained in the following steps.

CountryServiceClient.java

package com.tutorialspoint.client;

import org.springframework.ws.client.core.support.WebServiceGatewaySupport;
import com.tutorialspoint.GetCountryRequest;
import com.tutorialspoint.GetCountryResponse;

public class CountryServiceClient extends WebServiceGatewaySupport {
   public GetCountryResponse getCountryDetails(String country){
      String uri = "http://localhost:8080/countryService/";
      GetCountryRequest request = new GetCountryRequest();
      request.setName(country);

      GetCountryResponse response =(GetCountryResponse) getWebServiceTemplate()
         .marshalSendAndReceive(uri, request);
      return response;
   }
}

MainApp.java

package com.tutorialspoint;

import org.springframework.oxm.jaxb.Jaxb2Marshaller;
import com.tutorialspoint.client.CountryServiceClient;

public class MainApp {
   public static void main(String[] args) {
      CountryServiceClient client = new CountryServiceClient();
      Jaxb2Marshaller marshaller = new Jaxb2Marshaller();
      marshaller.setContextPath("com.tutorialspoint");
      client.setMarshaller(marshaller);
      client.setUnmarshaller(marshaller);
      GetCountryResponse response = client.getCountryDetails("United States");

      System.out.println("Country : " + response.getCountry().getName());
      System.out.println("Capital : " + response.getCountry().getCapital());
      System.out.println("Population : " + response.getCountry().getPopulation());
      System.out.println("Currency : " + response.getCountry().getCurrency());
   }
}

Start the Web Service

Start the Tomcat server and ensure that we can access other webpages from the webapps folder using a standard browser.

Test Web Service Client

Right click on the MainApp.java in your application under Eclipse and use run as Java Application command. If everything is ok with the application, it will print the following message.

Country : United States
Capital : Washington
Population : 46704314
Currency : USD

Here, we have created a Client – CountryServiceClient.java for the SOAP based web service. MainApp uses CountryServiceClient to make a hit to the web service, makes a post request and gets the data.

Spring WS – Unit Test Client

In this chapter, we will learn how to unit test a client created in the Spring WS – Writing Client for the web application server created in chapter Spring WS – Writing Server using Spring WS.

Step Description
1 Update the project countryService under the package com.tutorialspoint as explained in the Spring WS – Writing Server chapter.
2 Create CountryServiceClientTest.java under the package com.tutorialspoint under folder SRC → Test → Java as explained in steps given below.

CountryServiceClientTest.java

package com.tutorialspoint;

import static org.junit.Assert.*;

import org.junit.Assert;
import org.junit.Before;
import org.junit.Test;
import org.springframework.oxm.jaxb.Jaxb2Marshaller;

import com.tutorialspoint.client.CountryServiceClient;

public class CountryServiceClientTest {
   CountryServiceClient client;
   
   @Before
   public void setUp() throws Exception {
      client = new CountryServiceClient();
      Jaxb2Marshaller marshaller = new Jaxb2Marshaller();
      marshaller.setContextPath("com.tutorialspoint");
      client.setMarshaller(marshaller);
      client.setUnmarshaller(marshaller);
   }
   @Test
   public void test() {
      GetCountryResponse response = client.getCountryDetails("United States");
      Country expectedCountry = new Country();
      expectedCountry.setCapital("Washington");
      Country actualCountry = response.getCountry();
      Assert.assertEquals(expectedCountry.getCapital(), actualCountry.getCapital());
   }
}

Start the Web Service

Start the Tomcat server and ensure we are able to access other webpages from the webapps folder using a standard browser.

Unit Test Web Service Client

Let us open the command console, go to the C:MVNcountryService directory and execute the following mvn command.

C:MVNcountryService>mvn test

Maven will start building and testing the project.
