Spring AOP+AspectJ在XML配置实例

package com.zyiz.customer.bo;

public interface CustomerBo {

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

1. AspectJ <aop:before> = @Before

AspectJ @Before 示例.

package com.zyiz.aspect;

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

@Aspect
public class LoggingAspect {

	@Before("execution(* com.zyiz.customer.bo.CustomerBo.addCustomer(..))")
	public void logBefore(Joinzyiz joinzyiz) {
		//...
	}

} 

在XML同等功能，使用 <aop:before>.

<!-- Aspect -->
<bean id="logAspect" class="com.zyiz.aspect.LoggingAspect" />

<aop:config>

  <aop:aspect id="aspectLoggging" ref="logAspect" >

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

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

</aop:config>

2. AspectJ <aop:after> = @After

AspectJ @After 示例.

package com.zyiz.aspect;

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

@Aspect
public class LoggingAspect {

	@After("execution(* com.zyiz.customer.bo.CustomerBo.addCustomer(..))")
	public void logAfter(Joinzyiz joinzyiz) {
		//...
	}

} 

在XML同等功能，使用 <aop:after>实现。

<!-- Aspect -->
<bean id="logAspect" class="com.zyiz.aspect.LoggingAspect" />

<aop:config>

  <aop:aspect id="aspectLoggging" ref="logAspect" >

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

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

</aop:config>

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

AspectJ @AfterReturning 示例.

package com.zyiz.aspect;

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

@Aspect
public class LoggingAspect {

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

}

在XML同等功能 - 使用 <aop:after-returning>.

<!-- Aspect -->
<bean id="logAspect" class="com.zyiz.aspect.LoggingAspect" />

<aop:config>

  <aop:aspect id="aspectLoggging" ref="logAspect" >

    <!-- @AfterReturning -->
    <aop:pointcut id="pointCutAfterReturning"
      expression="execution(* com.zyiz.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 示例.

package com.zyiz.aspect;

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

@Aspect
public class LoggingAspect {

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

在XML同等功能 - 使用 <aop:after-throwing>.

<!-- Aspect -->
<bean id="logAspect" class="com.zyiz.aspect.LoggingAspect" />

<aop:config>

  <aop:aspect id="aspectLoggging" ref="logAspect" >

    <!-- @AfterThrowing -->
    <aop:pointcut id="pointCutAfterThrowing"
      expression="execution(* com.zyiz.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 示例.

package com.zyiz.aspect;

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

@Aspect
public class LoggingAspect {

	@Around("execution(* com.zyiz.customer.bo.CustomerBo.addCustomerAround(..))")
	public void logAround(ProceedingJoinzyiz joinzyiz) throws Throwable {
		//...
	}
	
}

在XML同等功能 - 使用 <aop:after-around>.

<!-- Aspect -->
<bean id="logAspect" class="com.zyiz.aspect.LoggingAspect" />

<aop:config>

   <aop:aspect id="aspectLoggging" ref="logAspect" >

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

</aop:config>
