log4j Spring aop 注解的日志管理

1.配置log4j配置文件

ERROR>INFO>DEBUG  
log4j.properties    
log4j.rootLogger=INFO,stdout,logfile,db  
              
#spring log  
log4j.logger.org.springframework=ERROR
log4j.logger.com.heruan.fsmanager.base=OFF  
  
  
#Console  
log4j.appender.stdout=org.apache.log4j.ConsoleAppender  
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout  
log4j.appender.stdout.layout.ConversionPattern=[log]:%d{yyyy-MM-dd HH:mm:ss}   执行人ID:%X{userId},执行人:%X{userName},包名:%X{packageName},执行类:%X{className},执行方法:%X{mothedName},持续时间:%X{durTime},返回结果:%X{result},状态:%X{status},描述:%X{info} %C%l%n 
  
#Filelogfile  
log4j.appender.logfile=org.apache.log4j.DailyRollingFileAppender  
log4j.appender.logfile.File=${FSManagementPlatform.root}/WEB-INF/logs/system.log
log4j.appender.logfile.DatePattern = '.'yyyy-MM-dd   
log4j.appender.logfile.layout=org.apache.log4j.PatternLayout  
log4j.appender.logfile.layout.ConversionPattern=[log]:%d{yyyy-MM-dd HH:mm:ss}   执行人:%X{userName},包名:%X{packageName},执行类:%X{className},执行方法:%X{mothedName},持续时间:%X{durTime},返回结果:%X{result},状态:%X{status},描述:%X{info}%n  
  
#JDBC Appender  
log4j.appender.db=org.apache.log4j.jdbc.JDBCAppender
log4j.appender.db.BufferSize=10
log4j.appender.db.driver=com.mysql.jdbc.Driver
log4j.appender.db.URL=jdbc\:mysql\://***.***.***.***\:3306/***
log4j.appender.db.user=***
log4j.appender.db.password=*******
log4j.appender.db.layout=org.apache.log4j.PatternLayout
log4j.appender.db.sql=insert into sys_log (userId,userName,time,durTime,level,packageName,className,mothedName,result,status,info) values ('%X{userId}','%X{userName}','%d{yyyy-MM-dd HH\:mm\:ss}','%X{durTime}','%X{level}','%X{packageName}','%X{className}','%X{mothedName}','%X{result}','%X{status}','%X{info}')

写一个用户拦截器：

package com.heruan.fsmanage.aspect;

import java.io.IOException;
import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;
import org.apache.log4j.MDC;

import com.heruan.fsmanage.basedevelop.utils.UniqueIdUtil;
import com.heruan.fsmanage.entity.basedevelop.SysUser;
/** 
 * @ClassName GetUserFilter
 * @PackageName com.heruan.fsmanage.aspect
 * @Description (得到SESSION中的用户)
 * @author law
 * @Date 2016-5-6 下午3:43:15
 */
public class GetUserFilter implements Filter {

    // 定义默认用户姓名
    private final static String DEFAULT_USER = "guest";

    public void destroy() {
    }

    public void doFilter(ServletRequest request, ServletResponse response,
            FilterChain chain) throws IOException, ServletException {
        HttpServletRequest req = (HttpServletRequest) request;
        HttpSession session = req.getSession();
        if (session == null) {
            Long id = UniqueIdUtil.getInstanceId();
            MDC.put("userId", id);
            MDC.put("userName", DEFAULT_USER);
        } else {
            SysUser user = (SysUser) session.getAttribute("userinfo");
            if (user == null) {
                Long id = UniqueIdUtil.getInstanceId();
                MDC.put("userId", id);
                MDC.put("userName", DEFAULT_USER);
            } else {
                MDC.put("userId", user.getId());
                MDC.put("userName", user.getUserName());
            }
        }

        chain.doFilter(request, response);
    }

    public void init(FilterConfig Config) throws ServletException {

    }
}

配置web.xml

    <!--由Spring载入的Log4j配置文件位置-->  
    <context-param>  
        <param-name>log4jConfigLocation</param-name>  
        <param-value>classpath:new_log4j.properties</param-value>  
    </context-param>  
    <!--Spring默认刷新Log4j配置文件的间隔,单位为millisecond-->  
    <context-param>  
        <param-name>log4jRefreshInterval</param-name>  
        <param-value>60000</param-value>  
     </context-param>  
  
    <!-- Log4jConfigListener会去log4j.propeties 读取配置文件;开一条watchdog线程每60秒扫描一下配置文件的变化 -->  
    <listener>  
        <listener-class>  
          org.springframework.web.util.Log4jConfigListener  
        </listener-class>  
    </listener>

<filter>  
<filter-name>GetUserFilter</filter-name>  
<filter-class>com.heruan.fsmanage.aspect.GetUserFilter</filter-class>  
   </filter>  
   <filter-mapping>  
<filter-name>GetUserFilter</filter-name>  
<url-pattern>/*</url-pattern>  
</filter-mapping>

自定义注解：

package com.heruan.fsmanage.annotation;

import java.lang.annotation.Documented;
import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;

/** 
 * @ClassName Action
 * @PackageName com.heruan.fsmanage.annotation
 * @Description 对方法信息进行描述
 * @author law
 * @Date 2016-5-25 下午4:23:04
 */
@Target({ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface Action {
    String description() default  "";
}

写基于注解的切面：

package com.heruan.fsmanage.aspect;

import java.lang.reflect.Method;

import org.apache.log4j.Logger;
import org.apache.log4j.MDC;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.Pointcut;
import org.aspectj.lang.reflect.MethodSignature;

import com.heruan.fsmanage.annotation.Action;

/** 
 * @ClassName LogAspect
 * @PackageName com.heruan.fsmanage.aspect
 * @Description TODO
 * @author law
 * @Date 2016-5-6 上午9:56:11
 */
@Aspect
public class LogAspect {
    private static Logger logger = Logger.getLogger(LogAspect.class);
    @Around("doLog()")
    public Object logDescp(ProceedingJoinPoint joinPoint)throws Throwable{
        Object result=null;
        String returnResult = "";
        int durTime = -1;
        String classInfo = joinPoint.getTarget().getClass().getName();
        String className = classInfo.substring(classInfo.lastIndexOf(".")+1,classInfo.length());
        String packageName = classInfo.substring(0,classInfo.lastIndexOf("."));
        String mothedName = joinPoint.getSignature().getName();
        MDC.put("className", className);
        MDC.put("packageName", packageName);
        MDC.put("mothedName", mothedName);
        String info = getMethodDescription(joinPoint);
        try{
            Long startTime = System.currentTimeMillis();
            result = joinPoint.proceed();
            Long endTime = System.currentTimeMillis();
            if(result!=null){
                returnResult = result.toString().replaceAll("'", "\"");
            }
            durTime=(int) (endTime-startTime);
            MDC.put("status", "成功");
            MDC.put("durTime", durTime);
            MDC.put("result", returnResult);
            MDC.put("info", info);
            MDC.put("level", "info");
            logger.info("任务成功:"+info);    
        }catch(Exception e){
            e.printStackTrace();
            MDC.put("status", "失败");
            MDC.put("durTime", durTime);
            MDC.put("result", returnResult);
            MDC.put("info", info);
            MDC.put("level", "error");
            logger.error("异常信息:"+e.getMessage(), e);
            throw e;
        }
        return result;
    }
    
    /**

    private static String getWEBINFAddress() {    
        String url = LogAspect.class.getResource("/").getPath();  //this.getClass().getResource("/").getPath()  
        return url;  
    }

     private static String getMethodDescription(JoinPoint joinPoint) throws Exception {  
        //获取实体类名
        String targetName = joinPoint.getTarget().getClass().getName();  
        //获取方法名
        String methodName = joinPoint.getSignature().getName();  
        //获取参数列表
        Object[] arguments = joinPoint.getArgs();
        //获取参数类型列表
        Class[] parameterTypes = ((MethodSignature)joinPoint.getSignature()).getMethod().getParameterTypes();
        //获取拦截到的方法
        Method method = joinPoint.getTarget().getClass().getMethod(methodName, parameterTypes);
        String description = "";
        //获取Action注解描述信息
        description = method.getAnnotation(Action.class).description();  
        return description;  
    } 
}

加入一条bean：

<bean id="logAspect" class="com.heruan.fsmanage.aspect.LogAspect" /> 

启用aop注解代理：

<aop:aspectj-autoproxy proxy-target-class="true" />
