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

import java.text.SimpleDateFormat;
import java.util.Arrays;
import java.util.Date;

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;
}
对于想要了解其他三种通知的可以参考这篇博文：点击打开链接
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
以上这篇aop注解方式实现全局日志管理方法就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持亿速云。
