(辦公)springboot配置aop處理請求.-有解無憂

最近專案用到springboot,就是需要配置一些東西.比如用aop處理請求.方法前通知獲取url,method,ip,類方法,引數,方法后通知,回傳引數,而且還可以記錄一下日志.下面是操作的代碼.

package com.imooc.shoptest001.aspect;

import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.*;
import org.springframework.stereotype.Component;
import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;

import javax.servlet.http.HttpServletRequest;

/**
 *  劉運通
 *  20190324
 *  作用實作攔截http請求.
 */
@Aspect
@Component //把這個檔案引入到Spring容器里面去.
public class HttpAspect {

    @Pointcut("execution(public * com.imooc.shoptest001.controller.UserController.*(..))")
    public void log(){

    }
    /**
     * 攔截那些方法.請求前.
     * JoinPoint 獲取類方法和類名物件.
     */
    @Before("log()")
    public void logBefore(JoinPoint joinPoint){
        System.out.println("攔截了getInfo方法");
        //url,method,ip,類方法,引數.
        //SpringBoot通過RequestContextHolder獲取HttpRequest和HttpResponse
        ServletRequestAttributes attributes = (ServletRequestAttributes)RequestContextHolder.getRequestAttributes();
        //javax.servlet.http.HttpServletRequest
        HttpServletRequest request = attributes.getRequest();
        System.out.println("url"+request.getRequestURL());
        System.out.println("method"+request.getMethod());
        System.out.println("ip"+request.getRemoteAddr());
        //類方法.
        System.out.println("類方法"+joinPoint.getSignature().getDeclaringTypeName()
                +"."+ joinPoint.getSignature().getName()
        );
        //引數:
        System.out.println("類方法"+joinPoint.getArgs());
    }
    /**
     * 攔截那些方法.請求后.
     */
    @After("log()")
    public void logAfter(){
        System.out.println("攔截了getInfo方法.之后");
    }

    /**
     * 回傳引數.
     * @param object 入參
     */
    @AfterReturning(returning = "object",pointcut = "log()")
    public void doAfterReturning(Object object){
        System.out.println(object);
    }



}
