相对于Spring本身的validation框架，
JSR 303校验显得更简单，易操作。
关键的两个文件如下：
User.java
package org.fkit.domain;
import java.io.Serializable;
import java.util.Date;
import javax.validation.constraints.Past;
import javax.validation.constraints.Pattern;
import org.hibernate.validator.constraints.Email;
import org.hibernate.validator.constraints.Length;
import org.hibernate.validator.constraints.NotBlank;
import org.hibernate.validator.constraints.Range;
import org.springframework.format.annotation.DateTimeFormat;
public class User implements Serializable {
/**
*
*/
private static final long serialVersionUID = 1L;
@NotBlank(message="登陆名不能为空")
private String loginName;
@NotBlank(message="密码不能为空")
@Length(min=6, max=8, message="密码长度必须在6位到8位之间")
private String password;
@NotBlank(message="用户名不能为空")
private String username;
@Range(min=15, max=60, message="年龄必须在15岁到60岁之间")
private int age;
@Email(message="必须是合法的邮箱地址")
private String email;
@DateTimeFormat(pattern="yyyy-MM-dd")
@Past(message="生日必须是一个过去的日期")
private Date birthDate;
@Pattern(regexp="[1][3,8][3,6,9][0-9]{8}", message="无效的电话号码")
private String phone;
public String getLoginName() {
return loginName;
}
public void setLoginName(String loginName) {
this.loginName = loginName;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public Date getBirthDate() {
return birthDate;
}
public void setBirthDate(Date birthDate) {
this.birthDate = birthDate;
}
public String getPhone() {
return phone;
}
public void setPhone(String phone) {
this.phone = phone;
}
}
