xml实现AOP切面

Posted 2020-09-27

一、applicationContext.xml

<?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:aop="http://www.springframework.org/schema/aop"
    xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/aop
        http://www.springframework.org/schema/aop/spring-aop.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd">
	
	<bean id="personService" class="com.lovo.u34.service.impl.PersonServiceImpl" ></bean>
	<bean id="myInterceptor" class="com.lovo.u34.service.MyInterceptor"></bean>
	
	<aop:config>
          <aop:pointcut expression="execution (* com.lovo.u34.service.impl.PersonServiceImpl.save(String))" id="personService1"/>
          <aop:aspect id="inter" ref="myInterceptor">
              <aop:before method="doAccessCheck" pointcut-ref="personService1"/>
              <aop:after method="doAfter" pointcut-ref="personService1"/>
              <aop:after-returning method="doAfterCheck" pointcut-ref="personService1"/>
          </aop:aspect>
    　　</aop:config> 
      
 	<context:annotation-config></context:annotation-config>
	<context:component-scan base-package="com"></context:component-scan>
	<aop:aspectj-autoproxy></aop:aspectj-autoproxy>
</beans>

二、PersonServiceImpl

public class PersonServiceImpl implements PersonService{
	@Override
	public void save(String name) {
		
		System.out.println("我是save方法"+name);
		//throw new RuntimeException("我爱例外");
	}

	@Override
	public void update(String name, Integer personid) {
		
		System.out.println("我是update方法");
	}

	@Override
	public String getPersonName(Integer personid) {
		
		System.out.println("我是getPersonName方法");
	
		return "xxx";
	}

}

三、MyInterceptor

public class MyInterceptor {

	public void doAccessCheck(){
		System.out.println("before前置方法"+"---");
	}
	
	public void doAfter(){ 
		System.out.println("after后置方法");
	}
	
	public void doAfterCheck(){
		System.out.println("afterReturning方法正常执行完毕之后执行"+"----");
	}
    
    public void doAfterThrow(){  
        System.out.println("例外通知"+"----");  
    }  
    
    public Object doBasicProfiling(ProceedingJoinPoint pjp) throws Throwable{  
        System.out.println("进入环绕通知");  
        Object object = pjp.proceed();//执行该方法  
        System.out.println("退出环绕方法");  
        return object;  
    }   
}
