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 />
   
     <context:component-scan base-package="com.gcx" />

<aop:aspectj-autoproxy proxy-target-class="true"/>

<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

  1 public class SystemLog {
  2     private String id;
  3 
  4     private String description;
  5 
  6     private String method;
  7 
  8     private Long logType;
  9 
 10     private String requestIp;
 11 
 12     private String exceptioncode;
 13 
 14     private String exceptionDetail;
 15 
 16     private String params;
 17 
 18     private String createBy;
 19 
 20     private Date createDate;
 21 
 22     public String getId() {
 23         return id;
 24     }
 25 
 26     public void setId(String id) {
 27         this.id = id == null ? null : id.trim();
 28     }
 29 
 30     public String getDescription() {
 31         return description;
 32     }
 33 
 34     public void setDescription(String description) {
 35         this.description = description == null ? null : description.trim();
 36     }
 37 
 38     public String getMethod() {
 39         return method;
 40     }
 41 
 42     public void setMethod(String method) {
 43         this.method = method == null ? null : method.trim();
 44     }
 45 
 46     public Long getLogType() {
 47         return logType;
 48     }
 49 
 50     public void setLogType(Long logType) {
 51         this.logType = logType;
 52     }
 53 
 54     public String getRequestIp() {
 55         return requestIp;
 56     }
 57 
 58     public void setRequestIp(String requestIp) {
 59         this.requestIp = requestIp == null ? null : requestIp.trim();
 60     }
 61 
 62     public String getExceptioncode() {
 63         return exceptioncode;
 64     }
 65 
 66     public void setExceptioncode(String exceptioncode) {
 67         this.exceptioncode = exceptioncode == null ? null : exceptioncode.trim();
 68     }
 69 
 70     public String getExceptionDetail() {
 71         return exceptionDetail;
 72     }
 73 
 74     public void setExceptionDetail(String exceptionDetail) {
 75         this.exceptionDetail = exceptionDetail == null ? null : exceptionDetail.trim();
 76     }
 77 
 78     public String getParams() {
 79         return params;
 80     }
 81 
 82     public void setParams(String params) {
 83         this.params = params == null ? null : params.trim();
 84     }
 85 
 86     public String getCreateBy() {
 87         return createBy;
 88     }
 89 
 90     public void setCreateBy(String createBy) {
 91         this.createBy = createBy == null ? null : createBy.trim();
 92     }
 93 
 94     public Date getCreateDate() {
 95         return createDate;
 96     }
 97 
 98     public void setCreateDate(Date createDate) {
 99         this.createDate = createDate;
100     }
101 }

 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 }

230             logger.error("==异常通知异常==");  
231             logger.error("异常信息:{}", ex.getMessage());  
232         }  
233          /*==========记录本地异常日志==========*/  
234         logger.error("异常方法:{}异常代码:{}异常信息:{}参数:{}", joinPoint.getTarget().getClass().getName() + joinPoint.getSignature().getName(), e.getClass().getName(), e.getMessage(), params);  
235   
236     }  
237     
238 }

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！！

 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 }

下面编写测试类

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

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！！
