折騰了一上午才順利的把這個跑通了，廢話不多說，上程式碼！

1.儲存過程返回一個String

CREATE PROCEDURE `sp_redblack_prize`(OUT result_record varchar(2000000)){……}

2.在mapper.xml中

在這裡要注意：Set resultType="map" on <select> element.  I think for stored proc output parms you either need a map, or an object with getters/setters. 

  <select id="spRedBlack" statementType="CALLABLE" parameterType="java.util.Map" 
   resultType="java.util.Map">
   	{CALL sp_redblack_prize(#{result,mode=OUT,jdbcType=VARCHAR}) } 
  </select>
 

String spRedBlack(Map param);

        HashMap params = new HashMap(); 
	params.put("result", ""); 
	this.gamblingRedBlackDAO.spRedBlack(params);
	String result = (String) params.get("result");

注：statementType的型別分為：

statement未預編譯；

prepared預編譯（預設）；

callable儲存過程；
