MyBatis：MyBatis操作MySQL存儲過程

一 . 數據庫中創建存儲過程，並查看創建結果

1.創建存儲過程

DROP procedure IF EXISTS net_procedure_request;
DELIMITER $$
CREATE procedure net_procedure_request(in select_type varchar(99))
BEGIN
   IF select_type='0' THEN
      select client_ip,request_size_all,from_unixtime(start_time,'%Y年%m月%d日-%H時:%i分:%S秒') as startTime from net_table_request;
   ELSEIF select_type='1' THEN
      select client_ip,request_size_all,from_unixtime(start_time,'%Y年%m月%d日-%H時:%i分') as startTime from net_table_request;
   ELSEIF select_type='2' THEN
      select client_ip,request_size_all,from_unixtime(start_time,'%Y年%m月%d日-%H時') as startTime from net_table_request;
   END IF;
END$$
DELIMITER ;

2.查看創建存儲過程結果

show procedure status;

3.導出創建存儲過程的語句

show create procedure net_procedure_request;

4.數據庫調用存儲過程

set @select_type='0';
call net_procedure_request(@select_type);

二 . MyBatis中調用存儲過程

<select id="getInfo" statementType="CALLABLE" resultMap="infoResultMap" parameterType="java.util.HashMap">
    {call net_procedure_request(#{select_type,mode=IN,jdbcType=VARCHAR},#{client_ip,mode=IN,jdbcType=VARCHAR})}
</select>

注意：select標簽中一定要加《statementType=“CALLABLE”》。
