Oracle自增長ID：

參考博客：Oracle數據庫創建表ID字段的自動遞增

mybatis語句

參考博客：點評 ibatis+oracle 批量插入的三種方法. 參考第三種

參考博客：mybatis中批量插入的兩種方式(高效插入)

Oracle自增長ID，如下：

序列：

   CREATE SEQUENCE  "ENERGY"."ROLE_OBJECT_SEQ"  MINVALUE 1 MAXVALUE 9999999999999999999999999999 INCREMENT BY 1 START WITH 150 NOCACHE  NOORDER  NOCYCLE ;
 

觸發器：

CREATE OR REPLACE TRIGGER TRIGGER_ROLE_OBJECT 
BEFORE INSERT ON SYS_RIGHT_ROLE_OBJECT FOR EACH ROW
BEGIN
  SELECT ROLE_OBJECT_SEQ.nextval into :new.ROLE_OBJECT_ID from dual;
END;

Mybatis ：

    <insert id="insertSelectiveByList" parameterType="java.util.List">
        insert into
        SYS_RIGHT_ROLE_OBJECT (ROLE_CODE,
        OBJECT_CODE,
        POLICY_ID, PERMISSION)
        
 
<foreach collection="list" item="item" index="index"  open="(" close=")" separator="UNION ALL">
            SELECT #{item.roleCode} AS ROLE_CODE,
            #{item.objectCode} AS OBJECT_CODE,
            #{item.policyId} AS POLICY_ID, #{item.permission} AS PERMISSION  FROM dual
        </foreach
 
>
    </insert>
