青旅半醒 2022-02-15 11:38 358阅读 0赞

[1，新建一个Maven项目，搭建SpringBoot框架，编写请求][1_Maven_SpringBoot]  
2，添加AOP依赖

<dependency>
    	    <groupId>org.springframework.boot</groupId>
    	  	<artifactId>spring-boot-starter-aop</artifactId>
        </dependency>
    	<dependency>
    		
    		<groupId>com.alibaba</groupId>
    		<artifactId>fastjson</artifactId>
    		<version>1.2.47</version>
    	</dependency>

3，新建一个Class，并添加@Aspect @Component标签

package com.c.sys.aop;
    
    import javax.servlet.http.HttpServletRequest;
    
    import org.aspectj.lang.JoinPoint;
    import org.aspectj.lang.annotation.AfterReturning;
    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 com.alibaba.fastjson.JSON;
    @Aspect
    @Component
    public class LoggerAop {
    
    	Logger logger=LoggerFactory.getLogger(getClass());
    	
    	@Pointcut("execution(* com.c.*.controller.*.*(..))")
    	public void logger() {}
    	@Before("logger()")
    	public void doBefore(JoinPoint joinPoint) {
    		StringBuffer buffer=new StringBuffer();
    		ServletRequestAttributes attributes=(ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
    		HttpServletRequest request=attributes.getRequest();
    		buffer.append("\n").append("**************************Request请求**************************").append("\n");
    		buffer.append("RequestMapper  :   "+request.getRequestURI()).append("\n");
    		buffer.append("ClassName      :   "+joinPoint.getSignature().getDeclaringTypeName()).append("\n");
    		buffer.append("MethodName     :   "+joinPoint.getSignature().getName()).append("\n");
    		buffer.append("Params         :   "+JSON.toJSONString(request.getParameterMap())).append("\n");
    		logger.info(buffer.toString());
    	}
    	@AfterReturning(value="logger()",returning="obj")
    	public void doAfter(JoinPoint joinPoint,Object obj) {
    		StringBuffer buffer=new StringBuffer();
    		buffer.append("\n");
    		buffer.append("Result         :   "+ obj).append("\n");
    		logger.info(buffer.toString());
    	}
    	
    }

3，打开浏览器进行浏览，并观察控制台打印日志
