How to convert java object correctly for jsonPath matcher?

Question

I'm writing mockMvc tests for my controller, and need to validate jsonPath return value.

Have tried differently with .is() and .value(), mapping, in any way i can imagine with no success

Loan loan = new Loan(
                "0000-0000",
                "OPEN",
                LocalDate.now(),
                LocalDate.now().plusDays(30),
                new BigDecimal("500.0"),
                new BigDecimal("50.0"),
                new BigDecimal("550.0"),
                new ArrayList<>()
        );

    Mockito.lenient()
            .when(loanService.loans())
            .thenReturn(Collections.singletonList(loan));

    String json = MAPPER.writeValueAsString(loan);

    mockMvc.perform(get("/api/loans"))
            .andExpect(jsonPath("$.*").value(json));



Expected :{"id":"0000-0000","status":"OPEN","created":"2019-05-09","dueDate":"2019-06-08","principal":500.0,"interest":50.0,"total":550.0,"extensions":[]}
Actual   :{id=0000-0000, status=OPEN, created=2019-05-09, dueDate=2019-06-08, principal=500.0, interest=50.0, total=550.0, extensions=[]}

So this is the closes i got, just dont get the types here.

In case you want to assert the complete responseBody as a json, you may use MockMvcResultMatchers's content method.

Just replace jsonPath("$.*").value(json) with content().json(json) as below

mockMvc.perform(get("/api/loans"))
            .andExpect(content().json(json));
