参考第四章添加AOP支持，SpringBoot使用Aop略有不同

一、添加pom依赖

<dependency>      <groupId>org.springframework.boot</groupId>      <artifactId>spring-boot-starter-aop</artifactId></dependency>

二、编写AOP切面

package com.container.monitor;import java.util.Arrays;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.core.annotation.Order;import org.springframework.stereotype.Component;import org.springframework.util.StringUtils;import org.springframework.web.context.request.RequestContextHolder;import org.springframework.web.context.request.ServletRequestAttributes;import com.alibaba.druid.support.json.JSONUtils;@Aspect@Componentpublic class ApiMonitor {    private static final Logger logger =  LoggerFactory.getLogger(ApiMonitor.class);    ThreadLocal<Long> startTime = new ThreadLocal<Long>();    @Pointcut("execution(public * com.container..*.controller.*Controller.*(..))")    @Order(1)    public void controllerPoint() {}    @Before("controllerPoint()")    public void doBeforeControllerPoint(JoinPoint joinPoint) {        ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();        HttpServletRequest request = attributes.getRequest();        logger.info("<====================================================================");        logger.info("请求来源:  => " + request.getRemoteAddr());        logger.info("请求URL: " + request.getRequestURL().toString());        logger.info("请求方式: " + request.getMethod());        logger.info("响应方法: " + joinPoint.getSignature().getDeclaringTypeName() + "." + joinPoint.getSignature().getName());        logger.info("请求参数 : " + Arrays.toString(joinPoint.getArgs()));        logger.info("---------------------------------------------------------------------");        startTime.set(System.currentTimeMillis());    }    @AfterReturning(pointcut="controllerPoint()", returning="rst")    public void  doAfterControllerPoint(JoinPoint joinPoint, Object rst) {        logger.info("耗时（毫秒） : " + (System.currentTimeMillis() - startTime.get()));        logger.info("返回数据: {}", JSONUtils.toJSONString(rst));        logger.info("====================================================================>");    }}
