代码块

1、 定义并实现对日志方面的处理。

import java.lang.reflect.Method;
import java.util.Arrays;
import java.util.Date;

import org.springframework.aop.AfterReturningAdvice;
import org.springframework.aop.MethodBeforeAdvice;


        @Override
        public void before(Method method1, Object[] arg1, Object arg2) throws Throwable {
            // TODO Auto-generated method stub
            System.out.println("   ");
            System.out.println("前置系统日志："+"当前时间："+(new Date())+":"+"调用了"+method1.getName()+" :使用了参数"+(Arrays.toString(arg1)));  
        }

        @Override
        public void afterReturning(Object arg0, Method method, Object[] args, Object arg2) throws Throwable {
            // TODO Auto-generated method stub
            System.out.println("后置系统日志："+"返回信息："+arg0+" "+"当前时间："+(new Date())+":"+
            "调用了"+method.getName()+" :使用了参数"+(Arrays.toString(args)));  

        }
}

2、定义业务代码1

public interface UserService {

    public void add(String name,String password);

    public void update(Integer id);
}

public class UserServiceimpl implements UserService{

    @Override
    public void add(String name,String password) {
        // TODO Auto-generated method stub
        System.out.println("注册--添加"+name +"   "+password);
    }

    @Override
    public void update(Integer id) {
        // TODO Auto-generated method stub
        System.out.println("修改");
    }

}

2、定义业务代码2

public interface IAdminService {
    public boolean login(String userName, String password);
}

public class AdminService implements IAdminService{

    @Override
    public boolean login(String userName, String password) {
        System.out.println("login:" + userName );
        return true;
    }

}

3、配置applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:mongo="http://www.springframework.org/schema/data/mongo"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
                        http://www.springframework.org/schema/beans/spring-beans-4.2.xsd
                        http://www.springframework.org/schema/context
                        http://www.springframework.org/schema/context/spring-context-4.2.xsd
                        http://www.springframework.org/schema/data/mongo
                        http://www.springframework.org/schema/data/mongo/spring-mongo-1.0.xsd
                        http://www.springframework.org/schema/aop
                        http://www.springframework.org/schema/aop/spring-aop-3.2.xsd">

    <bean id="logService" class="springAop.log.LogService"/> <!--处理日志方面的bean-->  
    <bean id="adminService" class="springAop.log.AdminService"/><!--处理业务的bean-->  
    <bean id="userService" class="springAop.log.UserServiceimpl"/><!--处理业务的bean-->  


    <!--将日志bean和业务bean通过代理的方式进行代理整合-->  

        <!-- 单个业务处理日志管理 -->
        <!-- <bean name="aopmethod" class="org.springframework.aop.framework.ProxyFactoryBean">  
            <property name="interceptorNames">  
               <list>  
                  <value>logService</value>  
                      此处还可以放置多个处理方面的bean  
               </list>  
           </property>  
           <property name="target" ref="adminService"></property>  
        </bean>    -->

      <!-- 多个业务处理日志管理 -->
        <bean name="logmanager" class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator">  
            <property name="interceptorNames">  
               <list>  
                  <value>logService</value>
                   <!--    此处还可以放置多个处理方面的bean   -->
               </list>  
           </property>  
           <property name="beanNames">
            <list>
                <value>adminService</value>
                <value>userService</value>
            </list>
           </property>  
        </bean>  
</beans>

4.测试类

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class TestMain {

    public static void testSpringAOP(){
        ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext.xml");
        IAdminService iAdminService =(IAdminService) applicationContext.getBean("adminService");
        iAdminService.login("huahua", "123456");
        UserService userService =(UserService) applicationContext.getBean("userService");
        userService.add("huahua1", "123456");
        userService.update(1);
    }
        public static void main(String[] args) {
            TestMain.testSpringAOP();
        }
}

运行结果：

前置系统日志：当前时间：Wed May 03 16:17:41 CST 2017:调用了login :使用了参数[huahua, 123456]
login:huahua
后置系统日志：返回信息：true 当前时间：Wed May 03 16:17:41 CST 2017:调用了login :使用了参数[huahua, 123456]

前置系统日志：当前时间：Wed May 03 16:17:41 CST 2017:调用了add :使用了参数[huahua1, 123456]

后置系统日志：返回信息：null 当前时间：Wed May 03 16:17:41 CST 2017:调用了add :使用了参数[huahua1, 123456]

前置系统日志：当前时间：Wed May 03 16:17:41 CST 2017:调用了update :使用了参数[1]
