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: true3、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)
@Documented
public @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

*/
@Before("controllerAspect()")
public void doBefore(JoinPoint joinPoint){
HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();
HttpSession session = request.getSession();

String ip = IpUtils.getIpAddr(request);

//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

*/
@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 ) {

}
}
try{

actionService.add(action);
}catch (Exception ex){

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

*/
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Devmax。
