Spring AOP + AspectJ in XML configuration example

For those don’t like annotation or using JDK 1.4, you can use AspectJ in XML based instead.

Review last customerBo interface again, with few methods, later you will learn how to intercept it via AspectJ in XML file.

package com.mkyong.customer.bo;

public interface CustomerBo {

	void addCustomer();
	
	String addCustomerReturnValue();
	
	void addCustomerThrowException() throws Exception;
	
	void addCustomerAround(String name);
}

1. AspectJ <aop:before> = @Before

AspectJ @Before example.

package com.mkyong.aspect;

import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;

@Aspect
public class LoggingAspect {

	@Before("execution(* com.mkyong.customer.bo.CustomerBo.addCustomer(..))")
	public void logBefore(JoinPoint joinPoint) {
		//...
	}

}

Equivalent functionality in XML, with <aop:before>.

<!-- Aspect -->
<bean  />

<aop:config>

  <aop:aspect  >

     <!-- @Before -->
     <aop:pointcut 
	expression="execution(* com.mkyong.customer.bo.CustomerBo.addCustomer(..))" />

     <aop:before method="logBefore" pointcut-ref="pointCutBefore" />
			
  </aop:aspect>

</aop:config>

2. AspectJ <aop:after> = @After

AspectJ @After example.

package com.mkyong.aspect;

import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.After;

@Aspect
public class LoggingAspect {

	@After("execution(* com.mkyong.customer.bo.CustomerBo.addCustomer(..))")
	public void logAfter(JoinPoint joinPoint) {
		//...
	}

}

Equivalent functionality in XML, with <aop:after>.

<!-- Aspect -->
<bean  />

<aop:config>

  <aop:aspect  >

     <!-- @After -->
     <aop:pointcut 
	expression="execution(* com.mkyong.customer.bo.CustomerBo.addCustomer(..))" />

     <aop:after method="logAfter" pointcut-ref="pointCutAfter" />
			
  </aop:aspect>

</aop:config>

3. AspectJ <aop:after-returning> = @AfterReturning

AspectJ @AfterReturning example.

package com.mkyong.aspect;

import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.AfterReturning;

@Aspect
public class LoggingAspect {

  @AfterReturning(
   pointcut = "execution(* com.mkyong.customer.bo.CustomerBo.addCustomerReturnValue(..))",
   returning= "result")
   public void logAfterReturning(JoinPoint joinPoint, Object result) {
	//...
   }

}

Equivalent functionality in XML, with <aop:after-returning>.

<!-- Aspect -->
<bean  />

<aop:config>

  <aop:aspect  >

    <!-- @AfterReturning -->
    <aop:pointcut 
      expression="execution(* com.mkyong.customer.bo.CustomerBo.addCustomerReturnValue(..))" />

    <aop:after-returning method="logAfterReturning" returning="result" 
      pointcut-ref="pointCutAfterReturning" />
			
  </aop:aspect>

</aop:config>

4. AspectJ <aop:after-throwing> = @AfterReturning

AspectJ @AfterReturning example.

package com.mkyong.aspect;

import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.AfterThrowing;

@Aspect
public class LoggingAspect {

  @AfterThrowing(
   pointcut = "execution(* com.mkyong.customer.bo.CustomerBo.addCustomerThrowException(..))",
   throwing= "error")
  public void logAfterThrowing(JoinPoint joinPoint, Throwable error) {
	//...
  }
}

Equivalent functionality in XML, with <aop:after-throwing>.

<!-- Aspect -->
<bean  />

<aop:config>

  <aop:aspect  >

    <!-- @AfterThrowing -->
    <aop:pointcut 
      expression="execution(* com.mkyong.customer.bo.CustomerBo.addCustomerThrowException(..))" />
			
    <aop:after-throwing method="logAfterThrowing" throwing="error" 
      pointcut-ref="pointCutAfterThrowing"  />
			
  </aop:aspect>

</aop:config>

5. AspectJ <aop:after-around> = @Around

AspectJ @Around example.

package com.mkyong.aspect;

import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Around;

@Aspect
public class LoggingAspect {

	@Around("execution(* com.mkyong.customer.bo.CustomerBo.addCustomerAround(..))")
	public void logAround(ProceedingJoinPoint joinPoint) throws Throwable {
		//...
	}
	
}

Equivalent functionality in XML, with <aop:after-around>.

<!-- Aspect -->
<bean  />

<aop:config>

   <aop:aspect  >

    <!-- @Around -->
   <aop:pointcut 
      expression="execution(* com.mkyong.customer.bo.CustomerBo.addCustomerAround(..))" />
			
   <aop:around method="logAround" pointcut-ref="pointCutAround"  />
			
  </aop:aspect>

</aop:config>
