aop註解方式實現全局日誌管理方法

1：日誌實體類

public class SysLog { /** */ private Integer id; /** 日誌描述*/ private String description; /** 執行的方法*/ private String method; /** 日誌類型0：操作日誌；1：異常日誌*/ private Integer logType; /** 客戶端請求的ip地址*/ private String requestIp; /** 異常代碼*/ private String exceptionCode; /** 異常詳細信息*/ private String exceptionDetail; /** 請求參數*/ private String params; /** 操作人*/ private String createBy; /** 操作時間*/ 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.exceptionDetail = 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：maven需要的jar

 <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>

這裡要求項目使用的是jdk1.7

3：springServlet-mvc.xml

 <!--proxy-target-class="true"強制使用cglib代理如果為false則spring會自動選擇--> <aop:aspectj-autoproxy proxy-target-class="true"/>

加上proxy-target-class="true"是為了可以攔截controller裡面的方法

4：定義切面，我這裡主要寫前置通知和異常通知

下面開始自定義註解

import java.lang.annotation.*;@Target({ElementType.PARAMETER, ElementType.METHOD}) @Retention(RetentionPolicy.RUNTIME) @Documented public @interface Log {/** 要執行的操作類型比如：add操作**/ public String operationType() default ""; /** 要執行的具體操作比如：添加用戶**/ public String operationName() default "";}

切麵類

} }

5：在controller裡面

/** * 根據用戶名去找密碼判斷用戶名和密碼是否正確* @author panliang * @param request * @param response * @throws IOException */@RequestMapping("/skipPage.do")@Log(operationType="select操作:",operationName="用戶登錄")//注意：這個不加的話，這個方法的日誌記錄不會被插入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){//登錄成功result=new ModelAndView("redirect:/login/dispacher_main.do");}else if(flag==2){//用戶名不存在result=new ModelAndView("redirect:/login/login.do?errorCode=1");} else{//密碼不正確result=new ModelAndView("redirect:/login/login.do?errorCode=2");}return result;}

對於想要了解其他三種通知的可以參考這篇博文：點擊打開鏈接

這樣用戶在訪問後台時，不管是正常訪問還是出現bug數據庫都有記錄
