@Valid 数据验证

用于javabean中字段的注解

Model 中

import lombok.Data;

import javax.persistence.*;
import javax.validation.constraints.Email;
import javax.validation.constraints.NotNull;
import java.util.concurrent.atomic.AtomicInteger;

/**

@Table(name = "blog_ip")
@Entity
@Data
public class BlogIp {
    private static AtomicInteger i = new AtomicInteger(0);
    @Id
    @GeneratedValue(strategy= GenerationType.AUTO)
    int id ;

    @Column
    @NotNull
    private String ip;

    @Column
    private String city;

    @Column
    private Integer rank;

    @Column
    @Email
    private String email;

}

方法中

//@Valid 表示 BlogIp要进行校验
public BlogIp newObject(@Valid BlogIp ip){
        blogIpRepository.save(ip);
        return ip;
    }
