oracle,mybatis主键自增长

<insert id="insert" parameterType="resource">
<selectKey resultType="long" order="BEFORE" keyProperty="id">
SELECT sys_resource_id_SEQ.NEXTVAL AS id FROM DUAL
</selectKey>
INSERT INTO <include refid="t_sys_resource"/>
(id, name, type, url, permission, parent_id, parent_ids, available)
VALUES
(#{id}, #{name}, #{type}, #{url}, #{permission}, #{parentId}, #{parentIds}, #{available})
</insert>

使用序列sequence,进行主键自增长

CREATE SEQUENCE  "PORTX"."SYS_ORGANIZATION_ID_SEQ"  MINVALUE 1 MAXVALUE 999999999999999999999999 INCREMENT BY 1 START WITH 1 CACHE 20 NOORDER  NOCYCLE ;
