aop註解方式實現全域日誌管理方法，aop管理方法

aop註解方式實現全域日誌管理方法，aop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：動作記錄；1：異常日誌*/ private Integer logType; /** 用戶端請求的ip地址*/ private String requestIp; /** 異常代碼*/ private String exceptionCode; /** 異常詳細資料*/ 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

下面開始自訂註解

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：添加使用者 **/  public String operationName() default "";}

切面類

   }    }      /** *  * @author： panliang * @time：2017-3-31 下午2:24:36 * @param joinPoint 切點  * @describtion：異常通知 用於攔截記錄異常日誌  */  @AfterThrowing(pointcut = "controllerAspect()", throwing="e")   public void doAfterThrowing(JoinPoint joinPoint, Throwable e) {     HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();

   }  }

5：在controller裡面

/** * 根據使用者名稱去找密碼 判斷使用者名稱和密碼是否正確 * @author panliang * @param request * @param response * @throws IOException  */@RequestMapping("/skipPage.do")@Log(operationType="select操作:",operationName="使用者登入")//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){//登入成功result=new ModelAndView("redirect:/login/dispacher_main.do");}else if(flag==2){//使用者名稱不存在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;}

這樣使用者在訪問後台時，不管是正常訪問還是出現bug資料庫都有記錄
