Implement the global log management method by using the aop annotation method and the aop Management Method

Implement the global log management method by using the aop annotation method and the aop Management Method

1: log entity class

Public class SysLog {/***/private Integer id;/** log description */private String description;/** method of execution */private String method; /** Log Type 0: Operation Log; 1: exception log */private Integer logType;/** IP Address requested by the client */private String requestIp; /** Exception Code */private String exceptionCode;/** exception details */private String exceptionDetail;/** request parameter */private String params; /** operator */private String createBy;/** operation time */private String createDate; public Integer getId () {return id;} public void setId (Integer id) {this. id = id;} public String getDescription () {return description;} public void setDescription (String description) {this. description = description;} public String getMethod () {return method;} public void setMethod (String method) {this. method = method;} public Integer getLogType () {return logType;} public void setLogType (Integer logType) {this. logType = logType;} public String getRequestIp () {return requestIp;} public void setRequestIp (String requestIp) {this. requestIp = requestIp;} public String getExceptionCode () {return exceptionCode;} public void setExceptionCode (String exceptionCode) {this. exceptionCode = exceptionCode;} public String getExceptionDetail () {return exceptionDetail;} public void setExceptionDetail (String exceptionDetail) {this. predictiondetail = exceptionDetail;} public String getParams () {return params;} public void setParams (String params) {this. params = params;} public String getCreateBy () {return createBy;} public void setCreateBy (String createBy) {this. createBy = createBy;} public String getCreateDate () {return createDate;} public void setCreateDate (String createDate) {this. createDate = createDate ;}}

2: jar required by maven

<dependency>    <groupId>org.aspectj</groupId>    <artifactId>aspectjrt</artifactId>    <version>1.7.4</version>   </dependency>  <dependency>    <groupId>org.aspectj</groupId>    <artifactId>aspectjweaver</artifactId>    <version>1.7.4</version>  </dependency> <dependency>    <groupId>cglib</groupId>    <artifactId>cglib</artifactId>    <version>2.1_3</version>  </dependency><dependency>  <groupId>org.springframework</groupId>  <artifactId>spring-aop</artifactId>  <version>4.2.5.RELEASE</version></dependency> 

The project is required to use jdk1.7.

3: springServlet-mvc.xml

<! -- Proxy-target-class = "true" Force cglib proxy to be used. If it is false, spring automatically selects --> <aop: aspectj-autoproxy proxy-target-class = "true"/>

Add proxy-target-class = "true" to intercept the methods in the controller.

4: definition section. Here I mainly write pre-notifications and exception notifications.

Start the custom annotation below

Import java. lang. annotation. *; @ Target ({ElementType. PARAMETER, ElementType. METHOD}) @ Retention (RetentionPolicy. RUNTIME) @ brief ented public @ interface Log {/** operation type to be executed, such as: add operation **/public String operationType () default ""; /** specific operations to be performed, such as: adding a user **/public String operationName () default "";}

5: In the controller

/*** Determine whether the user name and password are correct based on the user name * @ author panliang * @ param request * @ param response * @ throws IOException */@ RequestMapping ("/skipPage. do ") @ Log (operationType =" select Operation: ", operationName =" User Logon ") // Note: If this parameter is not added, the log records of this method are not inserted into public ModelAndView skipPage (HttpServletRequest request, HttpServletResponse response) throws IOException {ModelAndView result = null; String username = request. getParameter ("email"); String Password = request. getParameter ("password"); int flag = sysUserService. login (request, username, password); if (flag = 1) {// logon success result = new ModelAndView ("redirect:/login/dispacher_main.do ");} else if (flag = 2) {// the user name does not exist result = new ModelAndView ("redirect:/login. do? ErrorCode = 1 ");} else {// incorrect password result = new ModelAndView (" redirect:/login. do? ErrorCode = 2 ");} return result ;}

In this way, when users access the background, both normal access and bug database records are recorded.

The above aop annotation method implements the global log management method, which is a small part of the Content shared to everyone. I hope to give you a reference and support for the help house.
