ResultActions类型中的方法andExpect(ResultMatcher)不适用于参数(RequestMat

Question

我正在开发Spring MVC + Mockito，我已经开发了下面的代码，这导致了错误，不确定出了什么问题。

import static org.mockito.Mockito.verifyNoMoreInteractions;
import static org.mockito.Mockito.when;
import static org.springframework.test.web.client.match.MockRestRequestMatchers.content;
import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;
import java.util.Arrays;
import java.util.List;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.InjectMocks;
import org.mockito.Mock;
import org.mockito.MockitoAnnotations;
import org.springframework.http.MediaType;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.web.WebAppConfiguration;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;
import com.memorynotfound.config.WebConfig;
import com.memorynotfound.controller.UserController;
import com.memorynotfound.filter.CORSFilter;
import com.memorynotfound.model.User;
import com.memorynotfound.service.UserService;

@WebAppConfiguration
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = {WebConfig.class})
public class UserControllerUnitTest {
private MockMvc mockMvc;
@Mock
private UserService userService;
@InjectMocks
private UserController userController;
@Before
public void init(){
MockitoAnnotations.initMocks(this);
mockMvc = MockMvcBuilders.standaloneSetup(userController).addFilters(new CORSFilter()).build();
}
@Test
public void test_get_all_success() throws Exception{
List<User> users = Arrays.asList(
new User(1, "Daenerys Targaryen"),
new User(2, "John Snow"));
when(userService.getAll()).thenReturn(users);
mockMvc.perform(get("/users"))
.andExpect(status().isOk())
.andExpect(content().contentType(MediaType.APPLICATION_JSON_UTF8_VALUE))
.andExpect(jsonPath("$", hasSize(2)))
.andExpect(jsonPath("$[0].id", is(1)))
.andExpect(jsonPath("$[0].username", is("Daenerys Targaryen")))
.andExpect(jsonPath("$[1].id", is(2)))
.andExpect(jsonPath("$[1].username", is("John Snow")));
verify(userService, times(1)).getAll();
verifyNoMoreInteractions(userService);
}
}

我怀疑，与进口声明有关的东西不起作用。

@RestController
@RequestMapping("/users")
public class UserController {
private final Logger LOG = LoggerFactory.getLogger(UserController.class);
@Autowired
private UserService userService;
// =========================================== Get All Users ==========================================
@RequestMapping(method = RequestMethod.GET)
public ResponseEntity<List<User>> getAll() {
LOG.info("getting all users");
List<User> users = userService.getAll();
if (users == null || users.isEmpty()){
LOG.info("no users found");
return new ResponseEntity<List<User>>(HttpStatus.NO_CONTENT);
}
return new ResponseEntity<List<User>>(users, HttpStatus.OK);
}
}

以下是错误供参考：

Answer 1

我应该使用这个：

import static org.mockito.Mockito.*;
import static org.hamcrest.Matchers.*;
import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.*;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.*;
import java.util.Arrays;
import java.util.List;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.InjectMocks;
import org.mockito.Mock;
import org.mockito.MockitoAnnotations;
import org.springframework.http.*;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.web.WebAppConfiguration;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;
import com.memorynotfound.config.WebConfig;
import com.memorynotfound.controller.UserController;
import com.memorynotfound.filter.CORSFilter;
import com.memorynotfound.model.User;
import com.memorynotfound.service.UserService;

Answer 2

我也遇到了同样的问题。我发现有两个内容类；一个用于请求，另一个用于结果。

org.springframework.test.web.client.match.MockRestRequestMatchers.content;
org.springframework.test.web.servlet.result.MockMvcResultMatchers.content;

eclipse自动导入了第一个MockRestRequestMatchers.conf。正确的类是MockMvcResultMatchers.content。

如果添加以下导入并删除Eclipse导入的导入。它应该起作用。

import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.content;

Answer 3

有两种类型的内容类(请求、响应)。如果你想快速修复并添加所有你必须导入的方法：

import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.*;
import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.*;
