How to use MockMvcResultMatchers.jsonPath
提问by Pradeep Vairamani
MvcResult result = this.mockMvc.perform(
MockMvcRequestBuilders.get(mockUrl))
.andExpect(MockMvcResultMatchers.status().isOk())
.andExpect(MockMvcResultMatchers.content().contentType("application/ json;charset=UTF-8"))
.andDo(MockMvcResultHandlers.print())
Give me the following:
给我以下内容：
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 = []
However, testing it with
但是，测试它
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"))
returns the following error:

How do I use jsonPath?
我如何使用 jsonPath？
回答by Jose Martinez
I think you need to pass the Matcher to the jsonPathmethod. For example.
我认为您需要将 Matcher 传递给该jsonPath方法。例如。
public class Res {
String version;
public String getVersion() {
return version;
}
public void setVersion(String version) {
this.version = version;
}
}

Your code works for me just fine. I am using Hymanson to parse the cases and that's probably the only difference. Check my code:
你的代码对我来说很好。我正在使用 Hymanson 来解析案例，这可能是唯一的区别。检查我的代码：

结果类：
@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);

I can only recommend trying to change the Json parser library you are using. Otherwise, try to update your code with all the parts that are needed to create a simple, minimal and reproducible example of your problem.
我只能建议尝试更改您正在使用的 Json 解析器库。否则，尝试使用创建简单、最小和可重现的问题示例所需的所有部分来更新您的代码。
