SpringMVC 使用AOP添加日志

1 引入包

<dependency>  
       <groupId>org.aspectj</groupId>  
       <artifactId>aspectjweaver</artifactId>  
       <version>1.8.10</version>  
   </dependency>

2 切面类：

package cn.tnt.aop.util;
    
    import java.util.Arrays;
    
    import org.aspectj.lang.JoinPoint;
    import org.aspectj.lang.annotation.AfterReturning;
    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;
    
    @Component
    @Aspect
    public class LogAspect {
    	private static final Logger log=LoggerFactory.getLogger(LogAspect.class);
    	@Pointcut("execution(* cn.tnt.aop.service.*.*(..))")
    	public void logPointCut(){
    		
    	}
    	
    	@Before(value="logPointCut()")
    	public void logBefore(JoinPoint joinPoint){
    		String targetName = joinPoint.getTarget().getClass().getName();
    		String signatureName=joinPoint.getSignature().getName()+"()";
    		String params=Arrays.toString(joinPoint.getArgs());
    		log.info("------ METHOD BEFORE:"+targetName+"."+signatureName+"  params="+params);
    	}
    	
    	@AfterReturning(value="logPointCut()",returning="res")
    	public void logReturn(JoinPoint joinPoint,Object res){
    		String targetName = joinPoint.getTarget().getClass().getName();
    		String signatureName=joinPoint.getSignature().getName()+"()";
    		String params=Arrays.toString(joinPoint.getArgs());
    		log.info("------ METHOD RETURN:"+targetName+"."+signatureName+"  params="+params+"  response="+res);
    	}
    	
    	@AfterThrowing(value = "logPointCut()", throwing = "e")
        public void logThrowing(JoinPoint joinPoint, Throwable e) {
    		String targetName = joinPoint.getTarget().getClass().getName();
    		String signatureName=joinPoint.getSignature().getName()+"()";
    		String params=Arrays.toString(joinPoint.getArgs());
    		log.info("------ METHOD ERROR:"+targetName+"."+signatureName+"  params="+params+"  exception="+e);
        }
    }

3 扫描切面类所在的包并启动AaspectJ支持

<context:component-scan base-package="cn.tnt.aop.\*" />  
      
    <aop:aspectj-autoproxy proxy-target-class="true" />

经过上面3步，完成aspectj的应用。在调用service包下的任意类的方法时候会输出相应日志。

2018-10-30 14:06:11 INFO [cn.tnt.aop.util.LogAspect] ------ METHOD BEFORE:cn.tnt.aop.service.GoodsServiceImpl.query()  params=[2]
    2018-10-30 14:06:11 INFO [cn.tnt.aop.service.GoodsServiceImpl] ##########2
    2018-10-30 14:06:11 INFO [cn.tnt.aop.util.LogAspect] ------ METHOD RETURN:cn.tnt.aop.service.GoodsServiceImpl.query()  params=[2]  response={'goodsName':apple,'id':2}
