Spring Boot – Test – Validator:Validator的目标无效
作者:互联网
我在尝试运行测试时遇到以下错误:
org.springframework.web.util.NestedServletException:请求处理失败;嵌套异常是java.lang.IllegalStateException:Validator [userCreateFormValidator bean]的目标无效:com.ar.empresa.forms.UserCreateForm@15c3585
引起:java.lang.IllegalStateException:Validator [userCreateFormValidator bean]的目标无效:com.ar.empresa.forms.UserCreateForm@15c3585
在org.springframework.validation.DataBinder.assertValidators(DataBinder.java:567)
在org.springframework.validation.DataBinder.addValidators(DataBinder.java:578)
在com.ar.empresa.controllers.UserController.initBinder(UserController.java:36)
at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62)
at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43)
at java.lang.reflect.Method.invoke(Method.java:498)
代码是:
控制器:
@Controller
public class UserController {
private UserService userService;
private UserCreateFormValidator userCreateFormValidator;
@Autowired
public UserController(UserService userService, UserCreateFormValidator userCreateFormValidator) {
this.userService = userService;
this.userCreateFormValidator = userCreateFormValidator;
}
@InitBinder("form")
public void initBinder(WebDataBinder binder) {
binder.addValidators(userCreateFormValidator);
}
@PreAuthorize("hasAuthority('ADMIN')")
@RequestMapping(value = "/user/create", method = RequestMethod.GET)
public ModelAndView getUserCreatePage() {
return new ModelAndView("user_create", "form", new UserCreateForm());
}
@PreAuthorize("hasAuthority('ADMIN')")
@RequestMapping(value = "/user/create", method = RequestMethod.POST)
public String handleUserCreateForm(@Valid @ModelAttribute("form") UserCreateForm form, BindingResult bindingResult) {
if (bindingResult.hasErrors()) {
return "user_create";
}
try {
userService.create(form);
} catch (DataIntegrityViolationException e) {
bindingResult.reject("email.exists", "Email already exists");
return "user_create";
}
return "redirect:/users";
}
}
验证器:
@Component
public class UserCreateFormValidator implements Validator {
private final UserService userService;
@Autowired
public UserCreateFormValidator(UserService userService) {
this.userService = userService;
}
@Override
public boolean supports(Class<?> clazz) {
return clazz.equals(UserCreateForm.class);
}
@Override
public void validate(Object target, Errors errors) {
UserCreateForm form = (UserCreateForm) target;
validatePasswords(errors, form);
validateEmail(errors, form);
}
private void validatePasswords(Errors errors, UserCreateForm form) {
if (!form.getPassword().equals(form.getPasswordRepeated())) {
errors.reject("password.no_match", "Passwords do not match");
}
}
private void validateEmail(Errors errors, UserCreateForm form) {
if (userService.getUserByEmail(form.getEmail()).isPresent()) {
errors.reject("email.exists", "User with this email already exists");
}
}
}
UserCreateForm:
public class UserCreateForm {
@NotEmpty
private String email = "";
@NotEmpty
private String password = "";
@NotEmpty
private String passwordRepeated = "";
@NotNull
private Role role = Role.USER;
public String getEmail() {
return email;
}
public String getPassword() {
return password;
}
public String getPasswordRepeated() {
return passwordRepeated;
}
public Role getRole() {
return role;
}
public void setEmail(String email) {
this.email = email;
}
public void setPassword(String password) {
this.password = password;
}
public void setPasswordRepeated(String passwordRepeated) {
this.passwordRepeated = passwordRepeated;
}
public void setRole(Role role) {
this.role = role;
}
}
测试:
@RunWith(SpringRunner.class)
@SpringBootTest
public class UserControllerTest {
private MockMvc mockMvc;
private MediaType contentType = new MediaType(APPLICATION_JSON.getType(),
APPLICATION_JSON.getSubtype(),
Charset.forName("utf8"));
@MockBean
private UserService userService;
@MockBean
private UserCreateFormValidator userCreateFormValidator;
@Autowired
FilterChainProxy springSecurityFilterChain;
@Before
public void setup() {
this.mockMvc = MockMvcBuilders.standaloneSetup(new UserController(userService,userCreateFormValidator)).apply(SecurityMockMvcConfigurers.springSecurity(springSecurityFilterChain)).build();
}
@Test
@WithMockUser(username="user",
password="password",
roles="ADMIN")
public void homePage_authenticatedUser() throws Exception {
mockMvc.perform(get("/user/create"))
.andExpect(status().isOk())
.andExpect(view().name("user_create"));
}
}
我不知道为什么,因为它是一个GET方法,所以它不必验证它.
谢谢!
