MyBatis JPA Extra v2.7 GA 发布
时间:2021-12-28 18:14 来源:linux.it.net.cn 作者:IT
MyBatis JPA Extra对MyBatis进行了JPA扩展，旨在基于JPA 2.1的注释简化对单表CUID操作，根据JPA注释动态生成SQL语句；使用Interceptor实现数据库SELECT分页查询，适配多种数据库；另外提供mybatis-jpa-extra-spring-boot-starter简化SpringBoot集成。
MyBatis JPA Extra对MyBatis扩展JPA功能
1.基于JPA 2.1的注释简化CUID操作;
2.用Interceptor实现数据库SELECT分页查询;
3.提供mybatis-jpa-extra-spring-boot-starter,简化SpringBoot集成;
1、JavaBean注释简单
仅有6个注释
-
@Entity
-
@Table
-
@Column
-
@Id
-
@GeneratedValue
-
@Transient
@GeneratedValue有4中策略
-
AUTO
snowflakeid
uuid
uuid.hex
serial
-
SEQUENCE
generator值为数据库序列名
-
IDENTITY
generator无，根据数据库自动生成方式
package org.apache.mybatis.jpa.test.entity;
import java.io.Serializable;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
import org.apache.mybatis.jpa.persistence.JpaBaseEntity;
@Entity
@Table(name = "STUDENTS")
public class Students extends JpaBaseEntity implements Serializable{
private static final long serialVersionUID = -6928570405840778151L;
@Id
@Column
@GeneratedValue(strategy=GenerationType.AUTO,generator="snowflakeid")
//@GeneratedValue(strategy=GenerationType.SEQUENCE,generator="SEQ_MYBATIS_STUD")
//@GeneratedValue(strategy=GenerationType.IDENTITY,generator="SEQ_MYBATIS_STUD")
private String id;
@Column
private String stdNo;
@Column
private String stdName;
@Column
private String stdGender;
@Column
private int stdAge;
@Column
private String stdMajor;
@Column
private String stdClass;
@Column
private byte[] images;
public Students() {
super();
}
public get(){};
public void set(){};
//...
}
2、单表新增、修改、删除、查询、分页查询
