spring AOP自定义注解方式实现日志管理 详解

2017-06-06 00:45 991 查看


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



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 }


编写dao接口



1 package com.gcx.dao;
2
3 import com.gcx.entity.SystemLog;
4
5 public interface SystemLogMapper {
6     int deleteByPrimaryKey(String id);
7
8     int insert(SystemLog record);
9
10     int insertSelective(SystemLog record);
11
12     SystemLog selectByPrimaryKey(String id);
13
14     int updateByPrimaryKeySelective(SystemLog record);
15
16     int updateByPrimaryKey(SystemLog record);
17 }


编写service层



1 package com.gcx.service;
2
3 import com.gcx.entity.SystemLog;
4
5 public interface SystemLogService {
6
7     int deleteSystemLog(String id);
8
9     int insert(SystemLog record);
10
11     int insertTest(SystemLog record);
12
13     SystemLog selectSystemLog(String id);
14
15     int updateSystemLog(SystemLog record);
16 }


编写service实现类serviceImpl



1 package com.gcx.service.impl;
2
3 import javax.annotation.Resource;
4
5 import org.springframework.stereotype.Service;
6
7 import com.gcx.annotation.Log;
8 import com.gcx.dao.SystemLogMapper;
9 import com.gcx.entity.SystemLog;
10 import com.gcx.service.SystemLogService;
11
12 @Service("systemLogService")
13 public class SystemLogServiceImpl implements SystemLogService {
14
15     @Resource
16     private SystemLogMapper systemLogMapper;
17
18     @Override
19     public int deleteSystemLog(String id) {
20
21         return systemLogMapper.deleteByPrimaryKey(id);
22     }
23
24     @Override
25
26     public int insert(SystemLog record) {
27
28         return systemLogMapper.insertSelective(record);
29     }
30
31     @Override
32     public SystemLog selectSystemLog(String id) {
33
34         return systemLogMapper.selectByPrimaryKey(id);
35     }
36
37     @Override
38     public int updateSystemLog(SystemLog record) {
39
40         return systemLogMapper.updateByPrimaryKeySelective(record);
41     }
42
43     @Override
44     public int insertTest(SystemLog record) {
45
46         return systemLogMapper.insert(record);
47     }
48
49 }


到这里基本程序编写完毕

下面开始自定义注解

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 }


下面编写切面

1 package com.gcx.annotation;
2
3 import java.lang.reflect.Method;
4 import java.util.Date;
5 import java.util.UUID;
6
7 import javax.annotation.Resource;

9 import javax.servlet.http.HttpSession;

11 import org.aspectj.lang.JoinPoint;
12 import org.aspectj.lang.ProceedingJoinPoint;
13 import org.aspectj.lang.annotation.After;
14 import org.aspectj.lang.annotation.AfterReturning;
15 import org.aspectj.lang.annotation.AfterThrowing;
16 import org.aspectj.lang.annotation.Around;
17 import org.aspectj.lang.annotation.Aspect;
18 import org.aspectj.lang.annotation.Before;
19 import org.aspectj.lang.annotation.Pointcut;
20 import org.slf4j.Logger;
21 import org.slf4j.LoggerFactory;
22 import org.springframework.stereotype.Component;

219             log.setExceptionDetail(e.getMessage());
220             log.setMethod((joinPoint.getTarget().getClass().getName() + "." + joinPoint.getSignature().getName() + "()"));
221             log.setParams(params);
222             log.setCreateBy(user.getName());
223             log.setCreateDate(new Date());
224             log.setRequestIp(ip);
225             //保存数据库
226             systemLogService.insert(log);
227             System.out.println("=====异常通知结束=====");
228         }  catch (Exception ex) {
229             //记录本地异常日志
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     }

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!!
