SpringMVC后台校验

数据校验。(后台校验 hibernate validate)

引入jar包。

　　2. 在相应的实体类中加入注解。

public class User {

    @NotEmpty(message="账号不能为空")
    private String name;
    @Length(min=6,max=12,message="密码的长度【6~12】之间")
    private String password;
    @Pattern(regexp="^[1](([3|5|8][\\d])|([4][4,5,6,7,8,9])|([6][2,5,6,7])|([7][^9])|([9][1,8,9]))[\\d]{8}$",message="手机格式错误")
    private String phone;
    public String getPhone() {
        return phone;
    }
    public void setPhone(String phone) {
        this.phone = phone;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public String getPassword() {
        return password;
    }
    public void setPassword(String password) {
        this.password = password;
    }
    public User() {
        super();
    }
    public User(String name, String password, String phone) {
        super();
        this.name = name;
        this.password = password;
        this.phone = phone;
    }
    @Override
    public String toString() {
        return "User [name=" + name + ", password=" + password + ", phone=" + phone + "]";
    }
    
}
