  • spring AOP自定义注解方式实现日志管理

    转:spring AOP自定义注解方式实现日志管理

    今天继续实现AOP,到这里我个人认为是最灵活,可扩展的方式了,就拿日志管理来说,用Spring AOP 自定义注解形式实现日志管理。废话不多说,直接开始!!!

    关于配置我还是的再说一遍。

    在applicationContext-mvc.xml中要添加的

         <mvc:annotation-driven />
         <!-- 激活组件扫描功能,在包com.gcx及其子包下面自动扫描通过注解配置的组件 -->
         <context:component-scan base-package="com.gcx" />

      

         <!-- 启动对@AspectJ注解的支持 -->
         <!-- proxy-target-class等于true是强制使用cglib代理,proxy-target-class默认是false,如果你的类实现了接口 就走JDK代理,如果没有,走cglib代理  -->
         <!-- 注:对于单利模式建议使用cglib代理,虽然JDK动态代理比cglib代理速度快,但性能不如cglib -->

         <!--如果不写proxy-target-class="true"这句话也没问题-->
         <aop:aspectj-autoproxy proxy-target-class="true"/>

         <!--切面-->
         <bean id="systemLogAspect" class="com.gcx.annotation.SystemLogAspect"></bean>

    接下来开始编写代码。

         创建日志类实体

    View Code

         编写dao接口

    View Code

        编写service层

    View Code

       编写service实现类serviceImpl

    View Code

    到这里基本程序编写完毕

    下面开始自定义注解

    复制代码
     1 package com.gcx.annotation;
     2 
     3 import java.lang.annotation.*;
     4 
     5 @Target({ElementType.PARAMETER, ElementType.METHOD})  
     6 @Retention(RetentionPolicy.RUNTIME)  
     7 @Documented  
     8 public @interface Log {
     9 
    10     /** 要执行的操作类型比如:add操作 **/  
    11     public String operationType() default "";  
    12      
    13     /** 要执行的具体操作比如:添加用户 **/  
    14     public String operationName() default "";
    15 }
    复制代码

    下面编写切面

     我这里写的比较全,前置通知,环绕通知,后置通知,异常通知,后置饭后通知,都写上了,在我们实际编写中不写全也没事,我习惯上把记录日志的逻辑写在后置通知里面,我看网上也有些在前置通知里面的,但我感觉写在后置通知里比较好。

    下面开始在controller中加入自定义的注解!!

    复制代码
     1 package com.gcx.controller;
     2 
     3 import org.springframework.beans.factory.annotation.Autowired;
     4 import org.springframework.stereotype.Controller;
     5 import org.springframework.web.bind.annotation.RequestMapping;
     6 
     7 import com.gcx.annotation.Log;
     8 import com.gcx.service.UserService;
     9 
    10 @Controller
    11 @RequestMapping("userController")
    12 public class UserController {
    13 
    14     @Autowired
    15     private UserService userService;
    16     
    17     @RequestMapping("testAOP")
    18     @Log(operationType="add操作:",operationName="添加用户")  
    19     public void testAOP(String userName,String password){        
    20         userService.addUser(userName, password);
    21     }
    22 }
    复制代码

    下面编写测试类

    复制代码
    1 @Test
    2     public void testAOP1(){
    3         //启动Spring容器        
    4         ApplicationContext ctx = new ClassPathXmlApplicationContext(new String[]{"classpath:applicationContext-mvc.xml","classpath:applicationContext-dataSource.xml"});
    5         //获取service或controller组件
    6         UserController userController = (UserController) ctx.getBean("userController");
    7         userController.testAOP("zhangsan", "123456");
    8     }
    9     
    复制代码

    数据库数据:

    我原本想写两个切点,一个是service层,一个是controller层,service层是用来记录异常信息的日志,而controller层的是用来记录功能的日志,运行结果如下。    

    这样做的话不知道在实际的项目中运行效率好不好,在这里请看到博客的大牛给点建议!!

    生活源于拼搏!
