How to get user's id from response json

Question

I have mockmvc test.

@Test
    public void findAllUsers() throws Exception {
        mockMvc.perform(MockMvcRequestBuilders
                .get("http://localhost:8081/user/get")
                .accept(MediaType.APPLICATION_JSON))
                .andDo(print())
                .andExpect(status().isOk())
                .andExpect(content().contentType(MediaType.APPLICATION_JSON_UTF8))
                .andExpect(jsonPath("$", hasSize(2)))
                .andExpect(jsonPath("$[0].name", is("Ann")))
                .andExpect(jsonPath("$[0].products", hasSize(2)))
                .andExpect(jsonPath("$[1].name", is("John")))
                .andExpect(jsonPath("$[1].products", hasSize(1)));
    }

How can I get user id from this response to some additional variable?

For example I want something like this:

String id = jsonPath"$[0].id"; 

I know that it will not work, but I need to have user's id in variable.

You need to assign the result of you get call using andReturn() method. Then you can read the response content, read and assign your id to a variable. Please try :

MvcResult result = mockMvc.perform(MockMvcRequestBuilders
                .get("http://localhost:8081/user/get")
                .accept(MediaType.APPLICATION_JSON))
                .andDo(print())
                .andExpect(status().isOk())
                .andExpect(content().contentType(MediaType.APPLICATION_JSON_UTF8))
                .andExpect(jsonPath("$", hasSize(2)))
                .andExpect(jsonPath("$[0].name", is("Ann")))
                .andExpect(jsonPath("$[0].products", hasSize(2)))
                .andExpect(jsonPath("$[1].name", is("John")))
                .andExpect(jsonPath("$[1].products", hasSize(1)))
                .andReturn();
String content = result.getResponse().getContentAsString();
String id = JsonPath.read(content, "[0].id");
