表單引入 JSR303 後臺驗證

1 . 先看效果

2 . 引入相關jar包

3 . 配置springmvc.xml(不是web.xml)

附：

4 . 驗證條件寫在model裏面（下面的@size,@pattern,@Email是驗證條件，而@Id,@Column是配置多對一的東西，現在不用管他們）

import java.io.Serializable;
import java.util.Date;
import java.util.Set;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.OneToMany;
import javax.persistence.Table;
import javax.validation.constraints.Pattern;
import javax.validation.constraints.Size;

import org.hibernate.validator.constraints.Email;

@Entity
@Table(name = "exam_user")
public class UserHibernate implements Serializable {

	private static final long serialVersionUID = 7484295368856997107L;

	public UserHibernate() {
		super();
	}


	public String getUserId() {
		return userId;
	}


	public void setUserId(String userId) {
		this.userId = userId;
	}


	public String getUser_name() {
		return user_name;
	}

	public void setUser_name(String user_name) {
		this.user_name = user_name;
	}

	public String getPassword() {
		return password;
	}

	public void setPassword(String password) {
		this.password = password;
	}

	public String getEmail() {
		return email;
	}

	public void setEmail(String email) {

	}

	public String getGender() {
		return gender;
	}

	public void setGender(String gender) {
		this.gender = gender;
	}

	public String getBirthday() {
		return birthday;
	}

	public void setBirthday(String birthday) {

	}


	public Set<ExamUserRole> getExamUserRole() {

	}
	
	


	public Set<ExamUserSubject> getExamUserSubject() {

	}


	public void setExamUserSubject(Set<ExamUserSubject> examUserSubject) {
		this.examUserSubject = examUserSubject;
	}


	public void setExamUserRole(Set<ExamUserRole> examUserRole) {
		this.examUserRole = examUserRole;
	}
	

}

5 .   然後回到UserControler處理表單

5 . 錯誤信息顯示效果如最上面的圖片，驗證不通過就會在表單頁面顯示錯誤信息並停留在本頁面

6 . OK , JSR303後臺驗證已經講解完畢，謝謝您的支持
