Restful风格是现在开发中最常用的一种软件设计风格，springMvc在整合Restful风格的时候还需要配
置“hiddenHttpMethodFilter”，而SpringBoot 不需要，SpringBoot整合Restful只需要一下几个步骤：
Step1.新建一个SpringBoot项目，导入依赖，并解决跨域问题。
Step2.新建一个RestController来接收客户端的请求，代码如下：
package com.reset.controller; import com.reset.model.RestMessgae; import org.springframework.web.bind.annotation.*; import java.util.Map; /** * Created by chendai on 2018/3/19. */ @RestController public class TestController { /** * Restful Get请求测试 */ @GetMapping(value = "testRest/{id}") public RestMessgae testGetResetful(@PathVariable String id){ RestMessgae restMessgae = new RestMessgae(); System.out.println(id); return restMessgae; } /** * Restful Post请求测试 */ @PostMapping(value = "testRest") public String testPostRestful(@RequestBody Map<String,Object> map){ String id = (String)map.get("id"); System.out.println(id); return id; } /** * Restful Delete请求测试 */ @DeleteMapping(value = "testRest") public String testDeleteResetful(@RequestBody Map<String,Object> map){ String id = (String) map.get("id"); System.out.println(id); return id; } /** * Restful put请求测试 */ @PutMapping(value = "testRest") public String testPutResetful(@RequestBody Map<String,Object> map){ String id = (String) map.get("id"); System.out.println(id); return id; } }
注解说明：@RestController：代表的是这个类是用Restful风格来访问的，整个类的返回的数据都是“json”格式的。
@GetMapping 就是@RequestMapping(value="XXX",method=RequestMethod.Get)
value="testRest/{id}"代表访问的URL是“http://host:port/testRest/用户id”
@PathVariable将某个动态参数放到url中
@DeleteMapping、@PostMapping、@PutMapping含义和@GetMapping相同。
这样后台的Rest接口就完成了，前台发送请求是这样的：
var httpUrl = "http://localhost:8080"; // 发送get请求 function testRestfulGet() { $.ajax({ type: "GET", url: httpUrl + "/testRest/11", dataType: "json", contentType: "application/x-www-form-urlencoded", success: function (result) { console.log(result); }, error: function () { console.log(‘错误‘) } }) } //发送post请求 function testRestfulPost(){ var datas = {id:"123456"}; $.ajax({ type: "POST", url: httpUrl + "/testRest", dataType:"json", data: JSON.stringify(datas), contentType:"application/json;charset=utf-8", success: function (result) { console.log(result); }, error:function () { console.log(‘错误‘) } }) } //发送delete请求 function testRestfulDelete(){ var datas = {id:"123456"}; $.ajax({ type: "DELETE", url: httpUrl + "/testRest", dataType:"json", data:JSON.stringify(datas), contentType:"application/json;charset=utf-8", success: function (result) { console.log(result); }, error:function () { console.log(‘错误‘) } }) } //发送put请求 function testRestfulPut(){ var datas = {id:"123456"}; $.ajax({ type: "PUT", url: httpUrl + "/testRest", dataType:"json", data:JSON.stringify(datas), contentType:"application/json;charset=utf-8", success: function (result) { console.log(result); }, error:function () { console.log(‘错误‘) } }) }
