Spring(使用XML方式的AOP)

方法1:
<?
xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd " default-autowire="byName" > <context:annotation-config/> <context:component-scan base-package="com.daoan"/> <bean id="logIntercetor" class="com.daoan.aop.LogIntercetor"></bean> <aop:config> <!-- pointcut,在哪些方法上面加切面逻辑 --> <aop:pointcut expression="execution(public * com.daoan.service..*.add(..))" id="servicePointcut"/> <!-- 加入声明的切面对象 所参考的切面对象是logInterceptor --> <aop:aspect id="logAspect" ref="logInterceptor" > <!-- 在add方法执行之前,会先执行LogIntercetor下面的before()方法 --> <aop:before method="before" pointcut-ref="servicePointcut" /> </aop:aspect> </aop:config> </beans>

 

package com.daoan.aop;

import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.AfterReturning;
import org.aspectj.lang.annotation.AfterThrowing;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.Pointcut;
import org.springframework.stereotype.Component;

//@Aspect
//@Component
public class LogIntercetor {
    
    //(在方法执行之前先执行before()方法,如果需要把该逻辑织入到某个类的某个方法上,那个对象必须是spring管理起来的)
//    @Before("execution(public * com.daoan.service..*.add(..))")
    public void before() {
        System.out.println("method before");
    }
    
    //方法正常运行完成之后
//    @Around("execution(public * com.daoan.service..*.add(..))")
    public void aroundMethod(ProceedingJoinPoint pjp) throws Throwable {
        System.out.println("method around start");
        pjp.proceed();
        System.out.println("method around end");
    }
}

 

方法2:

    <context:annotation-config/>
    <context:component-scan base-package="com.daoan"/>
    
    <bean id="logIntercetor" class="com.daoan.aop.LogIntercetor"></bean>
    
    <aop:config>
        <!-- 加入声明的切面对象 所参考的切面对象是logInterceptor -->
        <aop:aspect id="logAspect" ref="logInterceptor" >
        <!-- 在add方法执行之前,会先执行LogIntercetor下面的before()方法 -->
            <aop:before method="before" pointcut="execution(public * com.daoan.service..*.add(..))" />
        </aop:aspect>
    
    </aop:config>
