aop注解方式实现全局日志管理方法

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

 
   org.aspectj 
   aspectjrt 
   1.7.4 
   
  
   org.aspectj 
   aspectjweaver 
   1.7.4 
  
 
   cglib 
   cglib 
   2.1_3 
 

  org.springframework
  spring-aop
  4.2.5.RELEASE

这里要求项目使用的是jdk1.7

3：springServlet-mvc.xml

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.lang.reflect.Method;
import java.text.SimpleDateFormat;
import java.util.Arrays;
import java.util.Date;
import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;

	 @Before("controllerAspect()")
	 public void doBefore(JoinPoint joinPoint) {
		/* System.out.println("==========执行controller前置通知===============");

		 HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest(); 
   HttpSession session = request.getSession(); 
   //读取session中的用户

   logger.error("异常方法:{}异常代码:{}异常信息:{}参数:{}", joinPoint.getTarget().getClass().getName() + joinPoint.getSignature().getName(), e.getClass().getName(), e.getMessage(), params); 
 
  } 
	 
}

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;
	}
