一、创建SpringBoot项目
二、配置文件:
1、启动文件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、属性文件,applicaiton.properties
server.port=6009
3、依赖文件,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 执行 test");
return "test";
}
}
5、拦截器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("拦截器1,如入参:" + queryString + "访问地址," + requestURL);
return true;
}
public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) {
System.out.println("拦截器2");
}
public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) {
System.out.println("拦截器3");
}
}
6、注册拦截器
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) {
//注册自定义拦截器,添加拦截路径和排除拦截路径
registry.addInterceptor(interceptorConfig).addPathPatterns("/job/**");
}
}
