SpringAOP日志管理

首先感谢大家写的有关AOP的博客&＃xff0c;本人参考了很多篇博客&＃xff0c;走了一点小弯路&＃xff0c;所以在此记录下配置的过程。 1、Mavan的相关依赖

org.springframeworkspring-aop3.2.2.RELEASEorg.springframeworkspring-aspects3.2.2.RELEASEorg.aspectjaspectjrt1.7.4

2、Spring 的配置文件

3、Struts2 的配置文件

4、日志实体&＃xff08;省略数据库的操作&＃xff09;

package com.gxuwz.entity;import javax.persistence.*;
&＃64;Entity
&＃64;Table(name &＃61; "sys_log")
public class SysLog extends BaseEntity{private static final long serialVersionUID &＃61; -2894437117210657269L;&＃64;Column(name &＃61; "log_ip_add")private String ipAdd; // IP地址&＃64;Column(name &＃61; "log_msg")private String msg; // 消息&＃64;Column(name &＃61; "log_method")private String method; // 方法&＃64;Column(name &＃61; "log_clazz")private String clazz; // 类名&＃64;Column(name &＃61; "log_username")private String username; // 用户名&＃64;Column(name &＃61; "log_create_date")private String createDate; //创建时间// 省略get、set的方法
}


5、自定义AOP的注解

package com.gxuwz.annotation;import java.lang.annotation.*;&＃64;Retention(RetentionPolicy.RUNTIME) //注解会在class中存在&＃xff0c;运行时可通过反射获取
&＃64;Target(ElementType.METHOD) //目标是方法
&＃64;Documented //文档生成时&＃xff0c;该注解将被包含在javadoc中&＃xff0c;可去掉
public &＃64;interface LogMsg
{String msg() default "";}


6、切面

package com.gxuwz.annotation;import org.apache.log4j.Logger;
import org.apache.struts2.ServletActionContext;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.Signature;
import org.aspectj.lang.annotation.*;
import org.aspectj.lang.reflect.MethodSignature;
import org.springframework.stereotype.Component;import com.gxuwz.entity.SysLog;
import com.gxuwz.entity.SysUser;
import com.gxuwz.service.ILogService;
import com.gxuwz.util.DateUtils;
import com.opensymphony.xwork2.ActionContext;import java.lang.reflect.Method;
import java.util.Map;import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;&＃64;Aspect
&＃64;Component
public class LogAspect {private static final Logger logger &＃61; Logger.getLogger(LogAspect.class);private SysLog log &＃61; new SysLog(); // 定义一个日志对象&＃64;Resource(name &＃61; "logService")private ILogService logService;/*** 定义Pointcut&＃xff0c;Pointcut的名称&＃xff0c;此方法不能有返回值&＃xff0c;该方法只是一个标示*/&＃64;Pointcut("&＃64;annotation(com.gxuwz.annotation.LogMsg)")public void controllerAspect() {System.out.println("我是一个切入点");}/*** 前置通知&＃xff08;Before advice&＃xff09; &＃xff1a;在某连接点&＃xff08;JoinPoint&＃xff09;之前执行的通知&＃xff0c;但这个通知不能阻止连接点前的执行。* * &＃64;param joinPoint*/&＃64;Before("controllerAspect()")public void doBefore(JoinPoint joinPoint) {System.out.println("&＃61;&＃61;&＃61;&＃61;&＃61;LogAspect前置通知开始&＃61;&＃61;&＃61;&＃61;&＃61;");// handleLog(joinPoint, null);}/*** 后通知&＃xff08;After advice&＃xff09; &＃xff1a;当某连接点退出的时候执行的通知&＃xff08;不论是正常返回还是异常退出&＃xff09;。* * &＃64;param joinPoint*/&＃64;AfterReturning(pointcut &＃61; "controllerAspect()")public void doAfter(JoinPoint joinPoint) {System.out.println("&＃61;&＃61;&＃61;&＃61;&＃61;LogAspect后置通知开始&＃61;&＃61;&＃61;&＃61;&＃61;");handleLog(joinPoint, null); // 等执行完SQL语句之后再记录&＃xff0c;避免获取不到Session}/*** 抛出异常后通知&＃xff08;After throwing advice&＃xff09; &＃xff1a; 在方法抛出异常退出时执行的通知。* * &＃64;param joinPoint* &＃64;param e*/&＃64;AfterThrowing(value &＃61; "controllerAspect()", throwing &＃61; "e")public void doAfter(JoinPoint joinPoint, Exception e) {System.out.println("&＃61;&＃61;&＃61;&＃61;&＃61;LogAspect异常通知开始&＃61;&＃61;&＃61;&＃61;&＃61;");// handleLog(joinPoint, e);}/*** 环绕通知&＃xff08;Around advice&＃xff09;* &＃xff1a;包围一个连接点的通知&＃xff0c;类似Web中Servlet规范中的Filter的doFilter方法。可以在方法的调用前后完成自定义的行为* &＃xff0c;也可以选择不执行。* * &＃64;param joinPoint*/&＃64;Around("controllerAspect()")public Object doAround(ProceedingJoinPoint joinPoint) throws Throwable {System.out.println("&＃61;&＃61;&＃61;&＃61;&＃61;LogAspect 环绕通知开始&＃61;&＃61;&＃61;&＃61;&＃61;");//handleLog(joinPoint, null);Object obj &＃61; joinPoint.proceed();System.out.println("&＃61;&＃61;&＃61;&＃61;&＃61;LogAspect 环绕通知结束&＃61;&＃61;&＃61;&＃61;&＃61;");return obj;}/*** 日志处理* * &＃64;param joinPoint* &＃64;param e*/private void handleLog(JoinPoint joinPoint, Exception e) {try {HttpServletRequest request &＃61; (HttpServletRequest) ActionContext.getContext().get(ServletActionContext.HTTP_REQUEST);System.out.println("IP地址&＃xff1a;" &＃43; request.getRemoteAddr());log.setIpAdd(request.getRemoteAddr());Map session &＃61; (Map) ActionContext.getContext().getSession();// 读取session中的用户SysUser user &＃61; (SysUser) session.get("user");System.out.println("用户名:" &＃43; user.getUserName());log.setUsername(user.getUserName());System.out.println("时间:"&＃43;DateUtils.getCurrentDate());log.setCreateDate(DateUtils.getCurrentDate());LogMsg logger &＃61; giveController(joinPoint);if (logger &＃61;&＃61; null) {return;}System.out.println("用户操作:"&＃43;logger.msg());log.setMsg(logger.msg());String signature &＃61; joinPoint.getSignature().toString(); // 获取目标方法签名String methodName &＃61; signature.substring(signature.lastIndexOf(".") &＃43; 1, signature.indexOf("("));//String longTemp &＃61; joinPoint.getStaticPart().toLongString();String classType &＃61; joinPoint.getTarget().getClass().getName();Class clazz &＃61; Class.forName(classType);Method[] methods &＃61; clazz.getDeclaredMethods();System.out.println("方法名:" &＃43; methodName);for (Method method : methods) {if (method.isAnnotationPresent(LogMsg.class)&& method.getName().equals(methodName)) {// OpLogger logger &＃61; method.getAnnotation(OpLogger.class);String clazzName &＃61; clazz.getName();log.setClazz(clazzName);log.setMethod(methodName);System.out.println("类名:" &＃43; clazzName &＃43; ", 方法名:"&＃43; methodName);}}logService.save(log); //保存日志对象} catch (Exception exp) {logger.error("异常信息:{}", exp);exp.printStackTrace();}}/*** 获得注解* * &＃64;param joinPoint* &＃64;return* &＃64;throws Exception*/private static LogMsg giveController(JoinPoint joinPoint)throws Exception {Signature signature &＃61; joinPoint.getSignature();MethodSignature methodSignature &＃61; (MethodSignature) signature;Method method &＃61; methodSignature.getMethod();if (method !&＃61; null) {return method.getAnnotation(LogMsg.class);}return null;}}

7、在Controller的方法上写注解、例如

/*** 用户控制器* &＃64;author 小胡 * &＃64;date 2017年5月28日*/
public class UserController extends AbstractBaseController{&＃64;LogMsg(msg &＃61; "用户登陆")public String doLogin(){...}
}
