1、引入springboot-aop集成jar
Spring-boot-start-aop
2、application.yml中启用声明
#spring配置spring: #切面启用 aop: proxy-target-class: true auto: true
3、自定义一个拦截controller的注解
package cn.annotation; import java.lang.annotation.*; /** * Title: SystemControllerLog * @date 2018年8月31日 * @version V1.0 * Description: 自定义注解，拦截controller */ @Target({ElementType.PARAMETER, ElementType.METHOD})//作用在参数和方法上@Retention(RetentionPolicy.RUNTIME)//运行时注解@Documented//表明这个注解应该被 javadoc工具记录public @interface SystemControllerLog { String description() default "";}4、自定义一个拦截service的注解
package cn.annotation; import java.lang.annotation.*; /** * Title: SystemControllerLog * @date 2018年8月31日 * @version V1.0 * Description: 自定义注解，拦截service */@Target({ElementType.PARAMETER, ElementType.METHOD})@Retention(RetentionPolicy.RUNTIME)@Documentedpublic @interface SystemServiceLog { String description() default "";}5、定义日志记录切面
package cn.annotation; import cn.pojo.Action;import cn.pojo.User;import cn.service.ActionService;import cn.utils.IpUtils;import cn.utils.JsonUtils;import org.aspectj.lang.JoinPoint;import org.aspectj.lang.annotation.AfterThrowing;import org.aspectj.lang.annotation.Aspect;import org.aspectj.lang.annotation.Before;import org.aspectj.lang.annotation.Pointcut;import org.slf4j.Logger;import org.slf4j.LoggerFactory;import org.springframework.stereotype.Component;import org.springframework.web.context.request.RequestContextHolder;import org.springframework.web.context.request.ServletRequestAttributes; import javax.annotation.Resource;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpSession;import java.lang.reflect.Method;import java.util.Date; /** * Title: SystemControllerLog * @date 2018年8月31日 * @version V1.0 * Description: 切点类 */@Aspect@Component@SuppressWarnings("all")public class SystemLogAspect { //注入Service用于把日志保存数据库，实际项目入库采用队列做异步 @Resource private ActionService actionService; //本地异常日志记录对象 private static final Logger logger = LoggerFactory.getLogger(SystemLogAspect.class); //Service层切点 @Pointcut("@annotation(cn.annotation.SystemServiceLog)") public void serviceAspect(){ } //Controller层切点 @Pointcut("@annotation(cn.oa.annotation.SystemControllerLog)") public void controllerAspect(){ } /** * @Description 前置通知 用于拦截Controller层记录用户的操作 * @date 2018年9月3日 10:38 */ @Before("controllerAspect()") public void doBefore(JoinPoint joinPoint){ HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest(); HttpSession session = request.getSession(); //读取session中的用户 User user = (User) session.getAttribute("user"); String ip = IpUtils.getIpAddr(request); try { //*========控制台输出=========*// System.out.println("==============前置通知开始=============="); System.out.println("请求方法" + (joinPoint.getTarget().getClass().getName() + "." + joinPoint.getSignature().getName())); System.out.println("方法描述：" + getControllerMethodDescription(joinPoint)); System.out.println("请求人："+user.getUsername()); System.out.println("请求ip："+ip); //*========数据库日志=========*// Action action = new Action(); action.setActionDes(getControllerMethodDescription(joinPoint)); action.setActionType("0"); action.setActionIp(ip); action.setUserId(user.getId()); action.setActionTime(new Date()); //保存数据库 actionService.add(action); }catch (Exception e){ //记录本地异常日志 logger.error("==前置通知异常=="); logger.error("异常信息：{}",e.getMessage()); } } /** * @Description 异常通知 用于拦截service层记录异常日志 * @date 2018年9月3日 下午5:43 */ @AfterThrowing(pointcut = "serviceAspect()",throwing = "e") public void doAfterThrowing(JoinPoint joinPoint,Throwable e){ HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest(); HttpSession session = request.getSession(); //读取session中的用户 User user = (User) session.getAttribute("user"); //获取请求ip String ip = IpUtils.getIpAddr(request); //获取用户请求方法的参数并序列化为JSON格式字符串 String params = ""; if (joinPoint.getArgs()!=null&&joinPoint.getArgs().length>0){ for (int i = 0; i < joinPoint.getArgs().length; i++) { params+= JsonUtils.objectToJson(joinPoint.getArgs()[i])+";"; } } try{ /*========控制台输出=========*/ System.out.println("=====异常通知开始====="); System.out.println("异常代码:" + e.getClass().getName()); System.out.println("异常信息:" + e.getMessage()); System.out.println("异常方法:" + (joinPoint.getTarget().getClass().getName() + "." + joinPoint.getSignature().getName() + "()")); System.out.println("方法描述:" + getServiceMethodDescription(joinPoint)); System.out.println("请求人:" + user.getUsername()); System.out.println("请求IP:" + ip); System.out.println("请求参数:" + params); /*==========数据库日志=========*/ Action action = new Action(); action.setActionDes(getServiceMethodDescription(joinPoint)); action.setActionType("1"); action.setUserId(user.getId()); action.setActionIp(ip); action.setActionTime(new Date()); //保存到数据库 actionService.add(action); }catch (Exception ex){ //记录本地异常日志 logger.error("==异常通知异常=="); logger.error("异常信息:{}", ex.getMessage()); } } /** * @Description 获取注解中对方法的描述信息 用于service层注解 * @date 2018年9月3日 下午5:05 */ public static String getServiceMethodDescription(JoinPoint joinPoint)throws Exception{ String targetName = joinPoint.getTarget().getClass().getName(); String methodName = joinPoint.getSignature().getName(); Object[] arguments = joinPoint.getArgs(); Class targetClass = Class.forName(targetName); Method[] methods = targetClass.getMethods(); String description = ""; for (Method method:methods) { if (method.getName().equals(methodName)){ Class[] clazzs = method.getParameterTypes(); if (clazzs.length==arguments.length){ description = method.getAnnotation(SystemServiceLog.class).description(); break; } } } return description; } /** * @Description 获取注解中对方法的描述信息 用于Controller层注解 * @date 2018年9月3日 上午12:01 */ public static String getControllerMethodDescription(JoinPoint joinPoint) throws Exception { String targetName = joinPoint.getTarget().getClass().getName(); String methodName = joinPoint.getSignature().getName();//目标方法名 Object[] arguments = joinPoint.getArgs(); Class targetClass = Class.forName(targetName); Method[] methods = targetClass.getMethods(); String description = ""; for (Method method:methods) { if (method.getName().equals(methodName)){ Class[] clazzs = method.getParameterTypes(); if (clazzs.length==arguments.length){ description = method.getAnnotation(SystemControllerLog.class).description(); break; } } } return description; }}6、开始使用
1）@SystemControllerLog(description = "")
注解加在控制器中方法上面，括号里写上操作描述
2）用于监控service异常，可以不使用
@SystemServiceLog(description = "")
注解加在service层方法上面，括号里写上操作描述
（此处为AOP拦截Service记录异常信息。方法不需要加try-catch）
以上为个人经验，希望能给大家一个参考，也希望大家多多支持。
