SpEL expression supports ternary operator to perform if-then-else logic.

Following example shows the various use cases.

Example

Let”s update the project created in Spring SpEL – Create Project chapter. We”re adding/updating following files −

• MainApp.java − Main application to run and test.

Here is the content of MainApp.java file −

package com.tutorialspoint;

import java.text.ParseException;
import org.springframework.expression.ExpressionParser;
import org.springframework.expression.spel.standard.SpelExpressionParser;

public class MainApp {
   public static void main(String[] args) throws ParseException {
      ExpressionParser parser = new SpelExpressionParser();

      String result = parser.parseExpression("true ? ''Yes'' : ''No''").getValue(String.class);
      System.out.println(result);

      result = parser.parseExpression("false ? ''Yes'' : ''No''").getValue(String.class);
      System.out.println(result);
   }
}

Output

Yes
No
