tk.mybatis实现uuid主键生成的示例代码

引入依赖

<dependency>
           <groupId>tk.mybatis</groupId>
           <artifactId>mapper-spring-boot-starter</artifactId>
           <version>2.0.2</version>
       </dependency>

1、创建一个GenId的实现类

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<String> {
   @Override
   public String genId(String s, String s1) {
       return UUID.randomUUID().toString().replace("-","");
   }
}

2、创建实体类

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;

/**
* 功能描述: 测试uuid主键生成
* @author xiaobu
* @date 2019/3/27 16:30
* @version 1.0
*/
@Data
public class TbDemo1 implements Serializable {
   /**
*
*/
   @Id
   @KeySql(genId = UUIdGenId.class)
   private String id;

/**
*
*/
   private String name;

private static final long serialVersionUID = 1L;
}

3、mapper类集成通用mapper

package com.xiaobu.mapper;

import com.xiaobu.base.mapper.MyMapper;
import com.xiaobu.entity.TbDemo1;
import org.apache.ibatis.annotations.Mapper;

/**
* 功能描述:继承通用mapper
* @author xiaobu
* @date 2019/3/27 17:06
* @version 1.0
*/
@Mapper
public interface TbDemo1Mapper extends MyMapper<TbDemo1> {

}

4、测试

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)
@SpringBootTest
public class TbDemo1Test {

@Autowired
   private TbDemo1Mapper tbDemo1Mapper;

@Test
   public void insert(){
       TbDemo1 tbDemo1 = new TbDemo1();
       tbDemo1.setName("测试uuid生成");
       tbDemo1Mapper.insert(tbDemo1);
       System.out.println("新增完成.....");
   }
}

tk.mapper的insertList不支持，自己写的插入方法也是不支持的。
