Mybatis实现批量插入数据且实现主键自增（将主键序列化）

----创建自增序列
CREATE SEQUENCE cpuTi_seq;
第一步 创建实体bean：

@Data
@Entity
@Table(name="reptile_cpu_record",schema="appuser")
public class CPUTime {
    @Id
    @Column(name="row_id")
    @GeneratedValue(strategy=GenerationType.SEQUENCE)
    private String rowId;
    @Column
    private String cpuTime;
    @Column
    private String executions;
    @Column
    private String cpuPerExec;
    @Column
    private String total;
    @Column
    private String elapsedTime;
    @Column
    private String cpu;
    @Column
    private String io;
    @Column
    private String sqlId;
    @Column
    private String sqlMoudle;
    @Column
    private String sqlText;
    @Column
    private Date createDate;
}

第二步 编写接口：

@Mapper
public interface ReptileRecordMapper {
   void insertCpuRec(List<CPUTime> cpuTis);
 }

第三步 编写service类：

@Service
@Slf4j
public class ReptileRecordService {
   @Autowired
   private ReptileRecordMapper recordMapper;
   public void addCpuRec(List<CPUTime> cpuTis){
       recordMapper.insertCpuRec(cpuTis);
   }  

sql 编写（mapper文件）:

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
  "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.ctg.dtts.tasktracker.mapper.ReptileRecordMapper">
   <insert id="insertCpuRec" parameterType="java.util.List">
      insert into appuser.reptile_cpu_record
         (row_Id,
         cpuTime,
         executions,
         cpuPerExec,
         total,
         elapsedTime,
         cpu,
         io,
         sqlId,
         sqlMoudle,
         sqlText,
         createDate
         )
      select cpuTi_seq.nextval,cpu.* from(
      <foreach collection="list" item="item" index="index" separator="union all">
         (select
         #{item.cpuTime},
         #{item.executions},
         #{item.cpuPerExec},
         #{item.total},
         #{item.elapsedTime},
         #{item.cpu},
         #{item.io},
         #{item.sqlId},
         #{item.sqlMoudle},
         #{item.sqlText},
         sysdate
         from dual)
      </foreach>
      ）cpu
    </insert>
  </mapper>

未将主键序列化，批量添加的代码如下：

<insert id="insertElapsRec" parameterType="java.util.List">
      insert into appuser.reptile_elapsed_record
      (row_Id,
       elapsedTime,
       executions,
       elapsedTimePerExec,
       total,
       cpu,
       io,
       sqlId,
       sqlMoudle,
       sqlText,
       createDate
       )

   <foreach collection="list" item="item" index="index" separator="union all">
      select
      '1'，
      #{item.elapsedTime},
      #{item.executions},
      #{item.elapsedTimePerExec},
      #{item.total},
      #{item.cpu},
      #{item.io},
      #{item.sqlId},
      #{item.sqlMoudle},
      #{item.sqlText},
      sysdate
      from dual
   </foreach>
   </insert>
