SpringBoot JPA的使用笔记

通过某一列查找数据：

SpringBoot有严格的命名规则，可以按照提示进行命名

userRepository.findByUidEquals(uId);

对应的实体类要与数据库一一对应【包括类名】

package com.narcos.seeu.po;

import lombok.Data;
import org.springframework.data.jpa.domain.AbstractPersistable;

import javax.persistence.*;

/**
 * @version V1.0
 * @ClassName：User
 * @author: hbj
 * @CreateDate：2018/8/10 10:43
 */
@Entity
@Data
public class User {
    @Id
    @Column(name = "id")
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Integer id;
    @Column(name = "uid")
    private Integer uid;
    @Column(name = "phone")
    private String phone;
    @Column(name = "password")
    private String password;
    @Column(name = "create_time")
    private Long createTime;
    @Column(name = "modify_time")
    private Long modifyTime;
}
