写一个控制器，加入一个接口

package com.niu.springbootinterceptor.controller;

import org.springframework.web.bind.annotation.GetMapping;

import org.springframework.web.bind.annotation.RestController;

/**

* @description: 控制器

* @author: nxq email: [e-mail]

* @createDate: 2020/12/22 3:28 下午

* @updateUser: nxq email: [e-mail]

* @updateDate: 2020/12/22 3:28 下午

* @updateRemark:

* @version: 1.0 **/

@RestController

public class MyController {

@GetMapping("test")

public Object test(){

System.out.println("test接口");

 return "ok";}

编写拦截器

package com.niu.springbootinterceptor.interceptor;

import org.springframework.web.servlet.HandlerInterceptor;

import org.springframework.web.servlet.ModelAndView;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

/**

* @description: 拦截器

* @author: nxq email: [e-mail]

* @createDate: 2020/12/22 3:26 下午

* @updateUser: nxq email: [e-mail]

 * @updateDate: 2020/12/22 3:26 下午

* @updateRemark:

* @version: 1.0 **/

public class MyInterceptor  implements HandlerInterceptor {
