*  Controller代码
 *  单元测试代码
 *  测试结果
 *  乱码解决

# 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/ */
    @RestController
    public 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 #

    @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

            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/ */
    @RestController
    public 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;
    
        }
    }

**解决乱码后的效果：**
