例如,我在实体上定义了以下约束：
@RooJavaBean
@RooToString
@RooJpaActiveRecord
public class Member {
@NotNull
@Email
@Column(unique = true)
private String email;
private String pseudo;
@NotNull
@Size(min = 6)
private String password;
@NotNull
@Size(min = 2)
private String firstName;
@NotNull
@Size(min = 2)
private String lastName;
@Temporal(TemporalType.DATE)
@DateTimeFormat(pattern = "dd/MM/yyyy")
private Date dateOfBirth;
@NotNull
@Enumerated
private Orientation orientation;
@NotNull
private String token;
@NotNull
@Temporal(TemporalType.TIMESTAMP)
@DateTimeFormat(pattern = "dd/MM/yyyy")
private Date registrationDate;
private boolean activated;
}
我还定义了一个在Spring MVC控制器中使用的辅助JavaBean.这里是：
@RooJavaBean
public class RegistrationInfo {
private Member member;
private String passwordConfirmation;
}
这是我的Spring MVC控制器中的相关代码：
@RequestMapping(value = "/registration",method = RequestMethod.POST,produces = "text/html")
public String registerMember(@modelattribute("registrationInfo") @Valid RegistrationInfo registrationInfo,Model model,BindingResult bindingResult) {
if (!registrationInfo.getMember().getPassword().equals(registrationInfo.getPasswordConfirmation())) {
bindingResult.addError(new ObjectError("member.password","passwords don't match"));
}
if (!registrationService.isEmailAvailable(registrationInfo.getMember().getEmail())) {
bindingResult.addError(new ObjectError("member.email","email already used"));
}
if (bindingResult.hasErrors()) {
//HOW TO ADD BEAN CONSTRAINTS VALIDATION ERRORS HERE????
populateForm(model,registrationInfo);
return "registration";
}
registrationService.registerMember(registrationInfo.getMember());
return "redirect:/";
}
从我的用户界面：
<div id="errors">
<ul th:if="${#fields.hasErrors('*')}">
<li th:each="err : ${#fields.errors('*')}" th:text="${err}"></li>
</ul>
</div>
但是,到目前为止,将要显示的唯一错误是我手动添加的错误(例如该bindingResult.addError)…
谁能提供建议？
编辑：如果我用@Valid注释成员变量,则在验证表单时会收到此异常：

最佳答案
将@Valid添加到RegistrationInfo内的member属性：
@RooJavaBean
public class RegistrationInfo {
private @Valid Member member;
private String passwordConfirmation;
}
然后在您的控制器方法中,bindingResult必须紧接在registrationInfo之后：
public String registerMember(@modelattribute("registrationInfo") @Valid RegistrationInfo registrationInfo,BindingResult bindingResult,Model model) {
