1:日志实体类
public class SysLog { /** */ private Integer id; /** 日志描述*/ private String description; /** 执行的方法*/ private String method; /** 日志类型 0:操作日志;1:异常日志*/ private Integer logType; /** 客户端请求的ip地址*/ private String requestIp; /** 异常代码*/ private String exceptionCode; /** 异常详细信息*/ private String exceptionDetail; /** 请求参数*/ private String params; /** 操作人*/ private String createBy; /** 操作时间*/ 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>
这里要求项目使用的是jdk1.7
3:springServlet-mvc.xml
<!--proxy-target-class="true"强制使用cglib代理 如果为false则spring会自动选择--> <aop:aspectj-autoproxy proxy-target-class="true"/>
加上proxy-target-class="true"是为了可以拦截controller里面的方法
4:定义切面,我这里主要写前置通知和异常通知
下面开始自定义注解
import java.lang.annotation.*; @Target({ElementType.PARAMETER, ElementType.METHOD}) @Retention(RetentionPolicy.RUNTIME) @Documented public @interface Log { /** 要执行的操作类型比如:add操作 **/ public String operationType() default ""; /** 要执行的具体操作比如:添加用户 **/ public String operationName() default ""; }
切面类

} }
5:在controller里面
/** * 根据用户名去找密码 判断用户名和密码是否正确 * @author panliang * @param request * @param response * @throws IOException */ @RequestMapping("/skipPage.do") @Log(operationType="select操作:",operationName="用户登录")//注意:这个不加的话,这个方法的日志记录不会被插入 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){//登录成功 result=new ModelAndView("redirect:/login/dispacher_main.do"); }else if(flag==2){//用户名不存在 result=new ModelAndView("redirect:/login/login.do?errorCode=1"); } else{//密码不正确 result=new ModelAndView("redirect:/login/login.do?errorCode=2"); } return result; }

这样用户在访问后台时,不管是正常访问还是出现bug数据库都有记录
