1、引入springboot-aop集成jar
Spring-boot-start-aop
2、application.yml中启用声明
1 2 3 4 5 6 | #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
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 | 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
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 | 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) @Documented public @interface SystemServiceLog { String description() default "" ; } |
5、定义日志记录切面
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 | 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 |
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
1 | @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IT俱乐部。
