我一直在努力解决这个问题，但没有运气，我对春季靴子也有点新意。此应用程序是用户注册应用程序。
我有一个服务，控制器类如下
@Service("userService")
@Transactional
public class UserService {
.....
}
@RestController
@RequestMapping("${" + Constants.USER_ROOT + "}")
public class UserController {
@PostMapping("${" + Constants.REGISTER_URL + "}")
public @ResponseBody Object register(@Valid @RequestBody User user, BindingResult bindingResult,HttpServletRequest request) {
.....
}
}
我正在为控制器编写测试用例，如下所示
@RunWith(SpringRunner.class)
@SpringBootTest(classes = { UserManagementServiceApplication.class })
public class UserControllerTest {
@MockBean
private UserRepository userRepository;
@MockBean
private UserService userService;
@Autowired
private WebApplicationContext webApplicationContext;
@MockBean
private User user;
@MockBean
private Environment env;
@Value("${" + Constants.USER_ROOT + "}" + "${" + Constants.REGISTER_URL + "}")
private String registerUrl;
@Value("${" + Constants.USER_ROOT + "}" + "${" + Constants.CONFIRM_REGISTER_URL + "}")
private String confirmRegisterUrl;
@Value("${" + Constants.USER_ROOT + "}" + "${" + Constants.RESET_PASSWORD_URL + "}")
private String resetPasswordUrl;
@Value("${" + Constants.USER_ROOT + "}" + "${" + Constants.CONFIRM_RESET_URL + "}")
private String confirmResetPasswordUrl;
private String email;
private MockMvc mockMvc;
private BCryptPasswordEncoder bCryptPasswordEncoder;
@Before
public void before() {
mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext).build();
bCryptPasswordEncoder = new BCryptPasswordEncoder();
user = new User();
email = "test" + System.currentTimeMillis() + "@test.com";
user.setEmail(email);
user.setFirstName("TestFirstName");
user.setLastName("TestLastName");
user.setPassword(bCryptPasswordEncoder.encode("Newuser@123"));
user.setEnabled(false);
user.setConfirmationToken("TestConfirmationToken");
}
@Test
public void createValidUserTest() throws Exception {
JSONObject testJSON = new JSONObject();
testJSON.put("email", email);
testJSON.put("password", "Newuser@123");
testJSON.put("firstName", "TestFirstName");
testJSON.put("lastName", "TestLastName");
// Mock
when(userService.findByEmail(email)).thenReturn(null);
when(userService.saveUser(user)).thenReturn(user);
when(userService.isUserExist(Constants.EMAIL, user.getEmail())).thenReturn(false);
when(userService.isPasswordWeak(user.getPassword())).thenReturn(false);
when(userService.encodePassword(user.getPassword())).thenReturn("Newuser@123_encoded");
when(userService.getProperty(Constants.USER_ROOT)).thenReturn(env.getProperty(Constants.USER_ROOT));
when(userService.getProperty(Constants.CONFIRM_URL)).thenReturn(env.getProperty(Constants.CONFIRM_URL));
mockMvc.perform(MockMvcRequestBuilders.post(registerUrl).contentType(MediaType.APPLICATION_JSON)
.content(testJSON.toString())).andExpect(MockMvcResultMatchers.status().isOk());
}
}
但是当我运行spring boot应用程序时，它会抛出一些奇怪的错误

请帮助我理解并解决此错误。
答案 0 :(得分：1)
发现了问题。问题是UserControllerTest中的org.springframework.core.env.Environment。
这不能被嘲笑，但是可以自动接线。
正在改变
@MockBean
private Environment env;
到
@Autowired
private Environment env;
解决了问题。
