MvcResult result = this.mockMvc.perform(
                MockMvcRequestBuilders.get(mockUrl))
                .andExpect(MockMvcResultMatchers.status().isOk())
            .andExpect(MockMvcResultMatchers.content().contentType("application/    json;charset=UTF-8"))
                .andDo(MockMvcResultHandlers.print())

会传回下列项目：

MockHttpServletResponse:
           Status = 200
    Error message = null
          Headers = {Content-Type=[application/json;charset=UTF-8]}
     Content type = application/json;charset=UTF-8
             Body = {"version":"0.1"}
    Forwarded URL = null
   Redirected URL = null
          Cookies = []

但是，使用

MvcResult result = this.mockMvc.perform(
                MockMvcRequestBuilders.get(mockUrl))
                .andExpect(MockMvcResultMatchers.status().isOk())
            .andExpect(MockMvcResultMatchers.content().contentType("application/    json;charset=UTF-8"))
                .andExpect(jsonPath("$.version").value("0.1"))

会传回下列错误：

我认为你需要把Matcher传递给jsonPath方法。

.andExpect(jsonPath("$.version", is("0.1")))

这是一个很好的例子，但是，如果你想让一个人在一段时间内完成一个任务，那么你就必须先完成这个任务，然后才能完成这个任务。

你的代码对我来说很好用。我使用Jackson来解析案例，这可能是唯一的区别。检查我的代码：
结果类别：

public class Res {
    String version;

    public String getVersion() {
        return version;
    }

    public void setVersion(String version) {
        this.version = version;
    }
}

控制器：

@RequestMapping(value = "/blah",
        method = GET,
        produces = APPLICATION_JSON_VALUE)
public HttpEntity<Res> doIt() {
    Res res = new Res();
    res.setVersion("0.1");
    return new HttpEntity<>(res);
}

测试项目：

@Test
public void blahTest() throws Exception {
    this.mockMvc.perform(
            MockMvcRequestBuilders.get("/blah"))
            .andExpect(MockMvcResultMatchers.status().isOk())
            .andExpect(MockMvcResultMatchers.content().contentType("application/json;charset=UTF-8"))
            .andExpect(jsonPath("$.version").value("0.1"))
            .andDo(MockMvcResultHandlers.print());
}

回应：

MockHttpServletResponse:
           Status = 200
    Error message = null
          Headers = {Content-Type=[application/json;charset=UTF-8]}
     Content type = application/json;charset=UTF-8
             Body = {"version":"0.1"}
    Forwarded URL = null
   Redirected URL = null
          Cookies = []

我只能建议您尝试更改您正在使用的Json解析器库。否则，请尝试更新您的代码，使其包含创建一个简单的、最小的、可重现的问题示例所需的所有部分。

这个答案的所有功劳都归@pramodh（隐藏在OP的评论中）
我有完全相同的问题，并安装他的reccomended依赖项修复了一切。

<dependency>
    <groupId>net.minidev</groupId>
    <artifactId>json-smart</artifactId>
    <version>2.3</version>
    <scope>test</scope>
