Controller代码

package com.keafmd.controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController;import java.util.HashMap;import java.util.Map;/** * Keafmd * * @ClassName: HelloController * @Description: * @author: 牛哄哄的柯南 * @Date: 2021-04-02 9:42 * @Blog: https://keafmd.blog.csdn.net/ */@RestControllerpublic class HelloController { @RequestMapping("/hello") Map hello(){  Map map = new HashMap();  map.put("keafmd","牛哄哄的柯南");  map.put("success",true);  return map; }}

单元测试代码

package com.keafmd;import com.keafmd.SpringBoot02Application;import com.keafmd.controller.HelloController;import org.junit.jupiter.api.BeforeEach;import org.junit.jupiter.api.Test;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.boot.test.autoconfigure.web.servlet.AutoConfigureMockMvc;import org.springframework.boot.test.context.SpringBootTest;import org.springframework.http.MediaType;import org.springframework.test.context.ContextConfiguration;import org.springframework.test.context.web.WebAppConfiguration;import org.springframework.test.web.servlet.MockMvc;import org.springframework.test.web.servlet.MvcResult;import org.springframework.test.web.servlet.request.MockMvcRequestBuilders;import org.springframework.test.web.servlet.result.MockMvcResultHandlers;import org.springframework.test.web.servlet.result.MockMvcResultMatchers;import org.springframework.test.web.servlet.setup.MockMvcBuilders;import org.springframework.web.context.WebApplicationContext;/** * Keafmd * * @ClassName: MvcTest * @Description: * @author: 牛哄哄的柯南 * @Date: 2021-04-02 10:59 * @Blog: https://keafmd.blog.csdn.net/ */@SpringBootTest(classes = SpringBoot02Application.class)@AutoConfigureMockMvc //相当于是使用 context 上下文构造一个 mvc对象public class MvcTest { //模拟访问 Controller @Autowired MockMvc mvc; @Test public void test() throws Exception {  MvcResult result = mvc.perform(    MockMvcRequestBuilders.get("/hello").      accept(MediaType.APPLICATION_JSON)).    andExpect(MockMvcResultMatchers.status().isOk()).    andDo(MockMvcResultHandlers.print()).andReturn(); }}

乱码解决

把注解替换为：↓
@RequestMapping(value = "/hello",produces = {"application/json;charset=UTF-8"})

HelloController：

package com.keafmd.controller;import org.springframework.web.bind.annotation.GetMapping;import org.springframework.web.bind.annotation.PostMapping;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController;import java.util.HashMap;import java.util.Map;/** * Keafmd * * @ClassName: HelloController * @Description: * @author: 牛哄哄的柯南 * @Date: 2021-04-02 9:42 * @Blog: https://keafmd.blog.csdn.net/ */@RestControllerpublic class HelloController { @RequestMapping(value = "/hello",produces = {"application/json;charset=UTF-8"}) //@RequestMapping("/hello") Map hello(){  Map map = new HashMap();  map.put("keafmd","牛哄哄的柯南");  map.put("success",true);  return map; }}
