MyBatis JPA Extra v2.7 GA 发布
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
@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
package org.apache.mybatis.jpa.test; import java.sql.Types; import java.text.SimpleDateFormat; import java.util.ArrayList; import java.util.Date; import java.util.List; import org.apache.mybatis.jpa.test.dao.service.StudentsService; import org.apache.mybatis.jpa.test.entity.Students; import org.apache.mybatis.jpa.util.WebContext; import org.junit.Before; import org.junit.Test; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; public class MyBatisTestRunner { private static final Logger _logger = LoggerFactory.getLogger(MyBatisTestRunner.class); public static ApplicationContext context; public static StudentsService service; @Test public void insert() throws Exception{ _logger.info("insert..."); Students student=new Students(); //student.setId("10024"); student.setStdNo("10024"); student.setStdGender("M"); student.setStdName("司马昭"); student.setStdAge(20); student.setStdMajor("政治"); student.setStdClass("4"); service.insert(student); Thread.sleep(1000); _logger.info("insert id " + student.getId()); //service.remove(student.getId()); } @Test public void merge() throws Exception{ _logger.info("merge..."); Students student=new Students(); //student.setId("10024"); student.setStdNo("10024"); student.setStdGender("M"); student.setStdName("司马昭"); student.setStdAge(20); student.setStdMajor("政治"); student.setStdClass("4"); service.merge(student); Thread.sleep(1000); _logger.info("insert id " + student.getId()); } @Test public void find() throws Exception{ _logger.info("find..."); _logger.info("find by filter " + service.find(" StdNo = '10024' or StdNo = '10004'") ); _logger.info("find by filter with args " + service.find( " StdNo = ? or StdNo = ?
