在Spring Boot应用中
1.添加Spring WebFlux依赖
2.使用
(1)Restful接口demoController.java
package com.example.demo.controller;import com.example.demo.domain.MyData;import org.springframework.http.HttpHeaders;import org.springframework.http.MediaType;import org.springframework.web.bind.annotation.*;import javax.servlet.http.Cookie;import javax.servlet.http.HttpServletRequest;@RestController@RequestMapping("/api")public class demoController { @GetMapping(value = "/getHeader", produces = {MediaType.APPLICATION_JSON_UTF8_VALUE}) public MyData getHeader(HttpServletRequest request) { int id = 0; if (request.getParameter("id") != null) { id = Integer.valueOf(request.getParameter("id")); } String name = request.getParameter("name"); //header String userAgent = "USER_AGENT——" + request.getHeader(HttpHeaders.USER_AGENT); userAgent += " | ACCEPT_CHARSET——" + request.getHeader(HttpHeaders.ACCEPT_CHARSET); userAgent += " | ACCEPT_ENCODING——" + request.getHeader(HttpHeaders.ACCEPT_ENCODING); userAgent += " | ContextPath——" + request.getContextPath(); userAgent += " | AuthType——" + request.getAuthType(); userAgent += " | PathInfo——" + request.getPathInfo(); userAgent += " | Method——" + request.getMethod(); userAgent += " | QueryString——" + request.getQueryString(); Cookie[] cookies = request.getCookies(); if (cookies != null) { for (Cookie cookie : cookies) { System.out.println(cookie.getName() + ":" + cookie.getValue()); } } MyData data = new MyData(); data.setId(id); data.setName(name); data.setOther(userAgent); return data; } @PostMapping(value = "/getPost", produces = {MediaType.APPLICATION_JSON_UTF8_VALUE}) public MyData getPost(HttpServletRequest request) { int id = 0; if (request.getParameter("id") != null) { id = Integer.valueOf(request.getParameter("id")); } String name = request.getParameter("name"); System.out.println(name + "," + id); MyData data = new MyData(); data.setId(id); data.setName(name); return data; } /** * POST传JSON请求 */ @PostMapping(value = "/getPostJson", produces = {MediaType.APPLICATION_JSON_UTF8_VALUE}) public MyData getPostJson(@RequestBody(required = true) MyData data) { System.out.println(data.getId()); System.out.println(data.getName()); return data; }}
MyData.java
package com.example.demo.domain;public class MyData { private int id; private String name; private String other; public int getId() { return id; } public void setId(int id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getOther() { return other; } public void setOther(String other) { this.other = other; }}
(2)WebClient使用
DemoApplicationTests.java
package com.example.demo;import com.example.demo.domain.MyData;import org.junit.Test;import org.springframework.http.HttpHeaders;import org.springframework.http.HttpMethod;import org.springframework.http.MediaType;import org.springframework.util.LinkedMultiValueMap;import org.springframework.util.MultiValueMap;import org.springframework.web.reactive.function.BodyInserters;import org.springframework.web.reactive.function.client.WebClient;import reactor.core.publisher.Mono;import java.time.Duration;import java.time.temporal.ChronoUnit;public class DemoApplicationTests { private WebClient webClient = WebClient.builder() .baseUrl("http://127.0.0.1:8080") .defaultHeader(HttpHeaders.USER_AGENT, "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko)") .defaultCookie("ACCESS_TOKEN", "test_token").build(); @Test public void WebGetDemo() { try { Mono
