validation - @NotNull、@Email 注释不起作用

Question

我正在尝试 spring MVC 的一些验证功能，但我无法让 @NotNull 和 @Email 工作，@Size 工作得很好，但其他 2 个似乎只是没有在 bindingresult 上报告错误。
任何人都可以给出一个想法。

package com.carloscortina.paidos.model;

import javax.validation.constraints.NotNull;
import javax.validation.constraints.Size;

import org.apache.commons.lang3.builder.ToStringBuilder;
import org.hibernate.validator.constraints.Email;
import org.hibernate.validator.constraints.ScriptAssert;

@ScriptAssert(lang="javascript",
         script="_this.confirmPassword.equals(_this.password)",
         message = "personal.password.mismatch.message")
public class PersonalRegistryForm {

private Long id;
private String pNombre,sNombre,apellidoP,apellidoM,
    username,password,confirmPassword,email,telCel,telefono,categoria;
boolean acceptTerms=true;

/**
 * @return the id
 */
public Long getId() {
    return id;
}
/**
 * @param id the id to set
 */
public void setId(Long id) {
    this.id = id;
}
/**
 * @return the pNombre
 */
public String getpNombre() {
    return pNombre;
}
/**
 * @param pNombre the pNombre to set
 */
public void setpNombre(String pNombre) {
    this.pNombre = pNombre;
}
/**
 * @return the sNombre
 */
public String getsNombre() {
    return sNombre;
}
/**
 * @param sNombre the sNombre to set
 */
public void setsNombre(String sNombre) {
    this.sNombre = sNombre;
}
/**

 */
public String getApellidoP() {
    return apellidoP;
}
/**

public void setApellidoP(String apellidoP) {
    this.apellidoP = apellidoP;
}
/**

 */
public String getApellidoM() {
    return apellidoM;
}
/**
 * @param apellidoM the apellidoM to set
 */
public void setApellidoM(String apellidoM) {
    this.apellidoM = apellidoM;
}
/**

@NotNull
@Size(min=4,max=12)
public String getUsername() {
    return username;

    this.username = username;

    return confirmPassword;

public void setConfirmPassword(String confirmPassword) {
    this.confirmPassword = confirmPassword;
}
/**
 * @return the email
 */
@NotNull
@Email
public String getEmail() {
    return email;
}
/**
 * @param email the email to set
 */
public void setEmail(String email) {
    this.email = email;
}
/**
 * @return the telCel
 */
public String getTelCel() {
    return telCel;
}
/**
 * @param telCel the telCel to set
 */

    this.telCel = telCel;
}

    this.acceptTerms = acceptTerms;

/* (non-Javadoc)

@Override

    ToStringBuilder builder = new ToStringBuilder(this);
    builder.append("id", id);
    builder.append("pNombre", pNombre);
    builder.append("sNombre", sNombre);
    builder.append("apellidoP", apellidoP);

Answer 1

看来这是我对验证的条款和功能的误解。
@NotNull 和 @Email 确实都在工作，但不像我想象的那样。
@NotNull 用于验证 Null 不为空，这是我的误解，同样@Email 无法对空字符串进行验证。

非常感谢阅读本文的每个人，我希望这可以帮助某人。它可能太菜鸟，但它很好学习。
