MyBatis：MyBatis操作MySQL存储过程

一 . 数据库中创建存储过程，并查看创建结果

1.创建存储过程

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

2.查看创建存储过程结果

show procedure status;

3.导出创建存储过程的语句

show create procedure net_procedure_request;

4.数据库调用存储过程

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

二 . MyBatis中调用存储过程

<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标签中一定要加《statementType=“CALLABLE”》。
