使用springMVC AOP实现日记记录

1 . 配置springmvc驱动，以及包扫描，还有AOP配置，如下：

2 . 引入相关jar包

3 . 目录树

4 . 编写日记记录类 LogInterceptor.java

package org.lee.Interceptor;
import java.lang.reflect.Method;
import java.util.Arrays;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.After;
import org.aspectj.lang.annotation.AfterReturning;
import org.aspectj.lang.annotation.AfterThrowing;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.Pointcut;
import org.aspectj.lang.reflect.MethodSignature;
import org.springframework.stereotype.Component;

@Component
@Aspect
public class LogInterceptor {
	
   /**
    * 这里针对org.lee.service.Imp目录下的新增，修改方法进行记录
    * */
	 @Pointcut("execution(* org.lee.service.Imp.*.*create*(..)) || execution(* org.lee.service.Imp.*.*edit*(..))")
	public void allMethod(){
		
	}
	 @Before("allMethod()") 
	 public void before(){  
	    }
	@After("allMethod()")
	public void afterLog(JoinPoint point){
		System.out.println("--------------afterLog:--------------最终通知");
		System.out.println("--------------afterLog:=========目标方法为："+point.getSignature().getDeclaringTypeName()+"."+point.getSignature().getName());
		System.out.println("--------------afterLog:--------------参数为："+Arrays.toString(point.getArgs()));
		System.out.println("--------------afterLog:--------------被织入的对象为："+point.getTarget());
		

	}
	
	@AfterReturning(value="allMethod()",returning="returnValue")
	public void afterRunningLog(JoinPoint point,Object returnValue ){
		System.out.println("--------------afterRunningLog--------------返回值后通知");
		System.out.println("--------------afterRunningLog----------------目标方法："+point.getSignature().getDeclaringTypeName()+"."+point.getSignature().getName());
		System.out.println("--------------afterRunningLog----------------参数为："+Arrays.toString(point.getArgs()));
		System.out.println("--------------afterRunningLog----------------返回值："+returnValue);	
		
		 
		
	}
	
	@AfterThrowing(value="allMethod()",throwing="ex")
	public void AfterThrowingLog(Throwable ex){
		System.out.println("--------------AfterThrowingLog--------------进入异常通知");
		System.out.println("--------------AfterThrowingLog--------------异常信息："+ex.getMessage());
	}
	
	
	@Around("allMethod()")
	public Object doAround(ProceedingJoinPoint p) throws Throwable{
		System.out.println("--------------Around--------------进入环绕通知");
		  long startTime = System.currentTimeMillis();  
		Object obj = p.proceed();
		  long endTime = System.currentTimeMillis();  
		  MethodSignature signature = (MethodSignature) p.getSignature();  
	        String methodName = signature.getDeclaringTypeName() + "." + signature.getName(); 
	        
		  System.out.println("目标方法："+methodName);
		  System.out.println("运行耗时："+(endTime-startTime)+"ms");
		System.out.println("--------------Around--------------结束方法调用");
		return obj;
		
	}
	

}
