introducing dependency tk.mybatis mapper-spring-boot-starter 2.0.2 1. Create an implementation class package com.xiaobu.base.entity; import tk.mybatis.mapper.genid.GenId; import java.util.UUID; /** * @author xiaobu * @version JDK1.8.0_171 * @date on 2019/3/27 11:37 * @description V1.0 */public class UUIdGenId implements GenId { @Override public String genId(String s, String s1) { return UUID.randomUUID().toString().replace("-",""); package com.xiaobu.entity; import com. xiaobu.base.entity.UUIdGenId;import lombok.Data;import tk.mybatis.mapper.annotation.KeySql; import javax.persistence.Id;import java.io.Serializable; /** * Function Description: Test uuid primary key generation * @author xiaobu * @date 2019/3/27 16:30 * @version 1.0 */@Datapublic class TbDemo1 implements Serializable { /** * */ @Id @KeySql(genId = UUIdGenId.class) private String id; /** * */ private String name; private static final long serialVersionUID = 1L;}3, Mapper class set into generic mapperpackage com.xiaobu.mapper; import com.xiaobu.base.mapper.MyMapper;import com.xiaobu.entity.TbDemo1;import org.apache.ibatis.annotations.Mapper; /** * Function Description: Continue to use Mapper * @author xiaobu * @date 2019/3/27 17:06 * @version 1.0 */@Mapperpublic interface TbDemo1Mapper extends MyMapper { }4, Test package com.xiaobu; import com.xiaobu.entity.TbDemo1;import com.xiaobu.mapper.TbDemo1Mapper;import org. junit.Test;import org.junit.runner.RunWith;import org. springframework.beans.factory.annotation.Autowired;import org. springframework.boot.test.context.SpringBootTest;import org.springframework.test.context.junit4.SpringRunner; /** * @author xiaobu * @version JDK1.8.0_171 * @date on 2019/3/27 11:11 * @description V1.0 */@RunWith(SpringRunner.class)@SpringBootTestpublic class TbDemo1Test { @Autowired private TbDemo1Mapper tbDemo1Mapper; @Test public void insert(){ TbDemo1 tbDemo1 = new TbDemo1(); tbDemo1.setName("Test uuid generation"); tbDemo1Mapper.insert(tbDemo1); System.out.println("Add complete... "); }}

tk.mapper insertList is not supported, and the insertion method written by yourself is also not supported.

At this point, the study of "tk.mybatis to achieve uuid primary key generation method is what" is over, I hope to solve everyone's doubts. Theory and practice can better match to help everyone learn, go and try it!
