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:
1 package com.heruan.fsmanage.aspect; 2 3 import java.io.IOException; 4 import javax.servlet.Filter; 5 import javax.servlet.FilterChain; 6 import javax.servlet.FilterConfig; 7 import javax.servlet.ServletException; 8 import javax.servlet.ServletRequest; 9 import javax.servlet.ServletResponse; 10 import javax.servlet.http.HttpServletRequest; 11 import javax.servlet.http.HttpSession; 12 import org.apache.log4j.MDC; 13 14 import com.heruan.fsmanage.basedevelop.utils.UniqueIdUtil; 15 import com.heruan.fsmanage.entity.basedevelop.SysUser; 16 /** 17 * @ClassName GetUserFilter 18 * @PackageName com.heruan.fsmanage.aspect 19 * @Description (得到SESSION中的用户) 20 * @author law 21 * @Date 2016-5-6 下午3:43:15 22 */ 23 public class GetUserFilter implements Filter { 24 25 // 定义默认用户姓名 26 private final static String DEFAULT_USER = "guest"; 27 28 public void destroy() { 29 } 30 31 public void doFilter(ServletRequest request, ServletResponse response, 32 FilterChain chain) throws IOException, ServletException { 33 HttpServletRequest req = (HttpServletRequest) request; 34 HttpSession session = req.getSession(); 35 if (session == null) { 36 Long id = UniqueIdUtil.getInstanceId(); 37 MDC.put("userId", id); 38 MDC.put("userName", DEFAULT_USER); 40 } else { 41 SysUser user = (SysUser) session.getAttribute("userinfo"); 42 if (user == null) { 43 Long id = UniqueIdUtil.getInstanceId(); 44 MDC.put("userId", id); 45 MDC.put("userName", DEFAULT_USER); 46 } else { 47 MDC.put("userId", user.getId()); 48 MDC.put("userName", user.getUserName()); 49 } 50 } 51 52 chain.doFilter(request, response); 53 } 54 55 public void init(FilterConfig Config) throws ServletException { 56 57 } 58 }
配置web.xml
1 <!--由Spring载入的Log4j配置文件位置--> 2 <context-param> 3 <param-name>log4jConfigLocation</param-name> 4 <param-value>classpath:new_log4j.properties</param-value> 5 </context-param> 6 <!--Spring默认刷新Log4j配置文件的间隔,单位为millisecond--> 7 <context-param> 8 <param-name>log4jRefreshInterval</param-name> 9 <param-value>60000</param-value> 10 </context-param> 11 12 <!-- 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 --> 13 <listener> 14 <listener-class> 15 org.springframework.web.util.Log4jConfigListener 16 </listener-class> 17 </listener> 18 19 <filter> 20 <filter-name>GetUserFilter</filter-name> 21 <filter-class>com.heruan.fsmanage.aspect.GetUserFilter</filter-class> 22 </filter> 23 <filter-mapping> 24 <filter-name>GetUserFilter</filter-name> 25 <url-pattern>/*</url-pattern> 26 </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; } /** * @Title getWEBINFAddress * @Description 获取WEB-INF路径 * @Author law * @CreateDate 2016-5-25 下午5:28:49 * @return String */ private static String getWEBINFAddress() { String url = LogAspect.class.getResource("/").getPath(); //this.getClass().getResource("/").getPath() return url; } /** * @Title getMethodDescription * @Description 获取注解中对方法的描述信息 * @Author law * @CreateDate 2016-5-26 下午2:36:43 * @param joinPoint * @throws Exception * @return 方法描述信息 */ 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" />
