使用AOP统一处理Web请求日志

pom.xml配置

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

写个切面类

package com.royal.web.aop;

import org.aspectj.lang.annotation.AfterReturning;

import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;
@Aspect
@Component
public class WebLogAspect {
    private Logger logger = Logger.getLogger(getClass());

    @Pointcut("execution(public * com.royal.web.controller..*.*(..))")
    public void webLog() {

    }

    @Before("webLog()")
    public void doBefore(JoinPoint joinPoint) throws Throwable {
        // 接收到请求，记录请求内容
        ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
        HttpServletRequest request = attributes.getRequest();
        // 记录下请求内容
        logger.info("---------------request----------------");

        Enumeration<String> enu = request.getParameterNames();
        while (enu.hasMoreElements()) {

            logger.info("name:" + name + "value" + request.getParameter(name));
        }
    }
    @AfterReturning(returning = "ret", pointcut = "webLog()")
    public void doAfterReturning(Object ret) throws Throwable {
        logger.info("---------------response----------------");
        // 处理完请求，返回内容
