一、創(chuàng)建SpringBoot項目
二、配置文件：
1、啟動文件InterceptortestApplication.java

package com.jane.interceptortest;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;

@SpringBootApplication
@ComponentScan("com.jane")
public class InterceptortestApplication {

    public static void main(String[] args) {
        SpringApplication.run(InterceptortestApplication.class, args);
    }

}

2、屬性文件，applicaiton.properties

server.port=6009

3、依賴文件，pom.xml

    4.0.0
    
        org.springframework.boot
        spring-boot-starter-parent
        2.1.4.RELEASE
         
    
    com.jane
    interceptortest
    0.0.1-SNAPSHOT
    interceptortest
    Demo project for Spring Boot

    
        1.8
    

    
        
            org.springframework.boot
            spring-boot-starter
        

        
            org.springframework.boot
            spring-boot-starter-test
            test
        
        
            org.springframework.boot
            spring-boot-starter-web
        
    

    
        
            
                org.springframework.boot
                spring-boot-maven-plugin
            
        
    

4、控制器，TestController

package com.jane.interceptortest.controller;

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

@RestController
@RequestMapping("/job")
public class TestController {

    @RequestMapping("/test")
    public String test() {
        System.out.println("RUL 執(zhí)行 test");
        return "test";
    }

}

5、攔截器TestInterceptor

package com.jane.interceptortest.interceptor;

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.HandlerInterceptor;
import org.springframework.web.servlet.ModelAndView;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

@Configuration
public class TestInterceptor implements HandlerInterceptor {

    public TestInterceptor(){}

    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) {
        String queryString = request.getQueryString();
        String requestURL = request.getRequestURL().toString();
        System.out.println("攔截器1，如入?yún)ⅲ? + queryString + "訪問地址，" + requestURL);
        return true;
    }

    public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) {
        System.out.println("攔截器2");
    }

    public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex)  {
        System.out.println("攔截器3");
    }

}

6、注冊攔截器

package com.jane.interceptortest.interceptor;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;

@Configuration
public class WebMvcConfg extends WebMvcConfigurationSupport {

    @Autowired
    private TestInterceptor interceptorConfig;

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        //注冊自定義攔截器，添加攔截路徑和排除攔截路徑
        registry.addInterceptor(interceptorConfig).addPathPatterns("/job/**");
    }

}

三、啟動運行
