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
