我想验证我的表单，但这不起作用。我的实体类

我有一个旧项目，在该项目中我使用了Java API中的Date，并且要将其更改为新的Java 8 Date API LocalDateTime。我读到5之前的Hibernate版本不支持新的Java 8 Date API，因此我决定从Hibernate 4.3.6迁移到5。在旧项目版本中，一切正常，但是当我更改Hibernate版本时，出现错误我尝试启动我的应用程序：

当我想编辑我的用户时,我的密码字段有问题.当我选择我的用户进行编辑时,我可以编辑名字,姓氏和密码,但我只能编辑名字并保持密码字段不变.当我单击编辑开始时,我收到一个错误:

The password field is empty.

我的密码字段:

<p:password id="password" value="#{userMB.user.password}" label="#{msg.password}" required="true">
    <f:validator validatorId="passwordValidator2" />   
    <p:ajax update="msgPassword" event="keyup" /> 
</p:password>

为什么？

当我改变它<p:password>与<h:inputText>它工作正常.但我看到密码我的用户...为什么<p:password>不读取初始值userMB.user.password？

我有一个Spring Validator:

@Component
public class AddClientAccountValidator implements Validator {

    @Autowired
    private ValidatorUtils validatorUtils;

    @Override
    public boolean supports(Class<?> clazz) {
        return UserDto.class.equals(clazz);
    }

    @Override
    public void validate(Object target, Errors errors) {
        UserDto user = (UserDto) target;
        validatorUtils.setParam(errors, user);

        ValidationUtils.rejectIfEmptyOrWhitespace(errors, "username", "username.required");
        ValidationUtils.rejectIfEmptyOrWhitespace(errors, "password", "password.required");
        ValidationUtils.rejectIfEmptyOrWhitespace(errors, "confirmPassword",
                "confirmPassword.required");
        ValidationUtils.rejectIfEmptyOrWhitespace(errors, "firstName", "firstName.required");
        ValidationUtils.rejectIfEmptyOrWhitespace(errors, "lastName", "lastName.required");
        ValidationUtils.rejectIfEmptyOrWhitespace(errors, "personalId", "personalId.required");
        ValidationUtils.rejectIfEmptyOrWhitespace(errors, "city", "city.required");
        ValidationUtils.rejectIfEmptyOrWhitespace(errors, "address", "address.required");
        ValidationUtils.rejectIfEmptyOrWhitespace(errors, "email", "email.required");
        ValidationUtils.rejectIfEmptyOrWhitespace(errors, "phone", "phone.required");
        ValidationUtils.rejectIfEmptyOrWhitespace(errors, "contribution", "contribution.required");

        validatorUtils.validateAddClientAccount();
    }
}

在上面的Validator中有注入ValidatorUtils类:

@Component
class ValidatorUtils {

    @Autowired
    private …
