mybatis调用存储过程实例

sqlMap:

<select id="proc_name" statementType="CALLABLE" parameterType="java.util.HashMap" resultType="java.lang.Integer">
{
call proc_name(
#{userId,mode=IN,jdbcType=INTEGER},
#{auditPoolId,mode=OUT,jdbcType=VARCHAR}
)
}
</select>

存储过程：

DELIMITER $$
CREATE PROCEDURE `databaseName`.`proc_name` (IN userId BIGINT(20), OUT auditPoolId INT)
BEGIN
DECLARE v_totalCount INT ;
DECLARE v_borrowId INT ;
-- 我的数量
SELECT
COUNT(*) totalCount
FROM
fk_audit_pool t
WHERE t.status = '1'
AND t.checkout_user_id = userId INTO v_totalCount ;
IF v_totalCount < 10
THEN
-- 获取最老的一条数据
SELECT
id,
t.xd_borrow_form_id
FROM
fk_audit_pool t
WHERE t.xd_borrow_form_id =
(SELECT
MAX(t.xd_borrow_form_id)
FROM
fk_audit_pool t
WHERE t.status = '0') INTO auditPoolId,v_borrowId ;

-- 修改状态
UPDATE
fk_audit_pool t
SET
t.status = '1',
t.checkout_user_id = userId,
t.checkout_time = SYSDATE()
WHERE t.xd_borrow_form_id = v_borrowId ;
END IF ;
END $$

DELIMITER ;

调用：

Map<String, Object> getOneMap = new HashMap<String, Object>();
getOneMap.put("userId", sysUser.getUserId());

dao.getOne("proc_name",paraMap);
Integer id = (Integer)  paraMap.get("auditPoolId");//存储过程的output参数，只能通过传入的map获取
