@PutMappingMockHttpServletResponse的JUnitRestControllerTest正文為空

我被困在一個控制器單元測驗 put 方法上，它總是回傳一個空的主體回應。

下面是我的代碼：

EmployeeServiceImpl.class

@Override
public Employee updateEmployee(Long id, Employee employee) {
    Employee existingEmployee = employeeRepository.findById(id)
            .orElseThrow(() -> new ResourceNotFoundException("employee with id: "   id   " does not exist."));

    existingEmployee.setFirstName(employee.getFirstName());
    existingEmployee.setLastName(employee.getLastName());
    existingEmployee.setEmail(employee.getEmail());

    return employeeRepository.save(existingEmployee);
}

EmployeeController.class 有 @RequestMapping("/api/employees")

@PutMapping("/{id}")
public ResponseEntity<Employee> updateEmployee(@PathVariable Long id, @RequestBody Employee employee) {
    return new ResponseEntity<>(employeeService.updateEmployee(id, employee), HttpStatus.OK);
}

EmployeeControllerTest.class

@Test
public void givenUpdatedEmployee_whenUpdateEmployee_thenReturnUpdatedEmployee() throws Exception {

    Long employeeId = 1L;

    Employee savedEmployee = Employee.builder()
            .id(employeeId)
            .firstName("Jay")
            .lastName("Lai")
            .email("[email protected]")
            .build();

    Employee updatedEmployee = Employee.builder()
            .id(employeeId)
            .firstName("Jayyy")
            .lastName("Laiii")
            .email("[email protected]")
            .build();

    BDDMockito.given(employeeService.getEmployeeBYId(employeeId))
            .willReturn(savedEmployee);

    BDDMockito.given(employeeService.updateEmployee(employeeId, updatedEmployee))
            .willReturn(updatedEmployee);

    ResultActions response = mockMvc.perform(MockMvcRequestBuilders.put("/api/employees/{id}", employeeId)
            .contentType(MediaType.APPLICATION_JSON)
            .content(mapper.writeValueAsString(updatedEmployee)));


    response.andDo(MockMvcResultHandlers.print())
            .andExpect(MockMvcResultMatchers.jsonPath("$.firstName", CoreMatchers.is(updatedEmployee.getFirstName())))
            .andExpect(MockMvcResultMatchers.jsonPath("$.lastName", CoreMatchers.is(updatedEmployee.getLastName())))
            .andExpect(MockMvcResultMatchers.jsonPath("$.email", CoreMatchers.is(updatedEmployee.getEmail())));
}

這是輸出。

我真的不明白我錯過了什么，任何幫助將不勝感激，謝謝。

MockHttpServletRequest:
  HTTP Method = PUT
  Request URI = /api/employees/1
   Parameters = {}
      Headers = [Content-Type:"application/json;charset=UTF-8", Content-Length:"73"]
         Body = {"id":1,"firstName":"Jayyy","lastName":"Laiii","email":"[email protected]"}
Session Attrs = {}

Resolved Exception:
         Type = null

ModelAndView:
    View name = null
         View = null
        Model = null

FlashMap:
   Attributes = null

MockHttpServletResponse:
       Status = 200
Error message = null
      Headers = []
 Content type = null
         Body = 
Forwarded URL = null
   Redirected URL = null
      Cookies = []

**java.lang.AssertionError: No value at JSON path "$.firstName"**

uj5u.com熱心網友回復：

問題就在這里

BDDMockito.given(employeeService.updateEmployee(employeeId, updatedEmployee))

因為您通過 Controller 的 PUT 請求正文是 a JSON，而不是Employee. 換句話說，您在 test 類中指定的 與 inupdatedEmployee不匹配，因此該陳述句無法按您的預期作業。結果，您得到了一個空的回應正文。employeeEmployeeServiceImplgiven...when...

您應該將您的given...when...宣告修改為

BDDMockito.given(employeeService.updateEmployee(eq(employeeId), any()))

那么它將正常作業。
