----mybatis調用orcle存儲過程,參數類型是map

<select id="queryTableNum" statementType="CALLABLE" parameterType="java.util.Map">

  {call INSERT_MAT_ID_PROCEDURE(#{inPrdPlanId,mode=IN,jdbcType=VARCHAR},#{inMatId,mode=IN,jdbcType=VARCHAR},#{results,mode=OUT,jdbcType=VARCHAR})}

 </select>

---Mybatis調用存儲過程並獲取out參數

mapper調用存儲過程

<select id="updateName" statementType="CALLABLE" parameterType="java.util.Map" resultType="java.util.Map"> 
call UPDATE_PRO_NAME(#{oldName,mode=IN,jdbcType=VARCHAR},
#{newName,mode=IN,jdbcType=VARCHAR},
#{results,mode=OUT,jdbcType=VARCHAR})  
  </select>

service層傳參並獲取out參數

//測試調用存儲過程
HashMap<String, Object> map = new HashMap<String, Object>();
map.put("oldName","張三");
map.put("newName","李四");
map.put("results","");//out參數,傳一個空串

                //這裏如果再用一個map來接收返回值,返回值會是null,直接調用就行了,過程會將out參數輸出到傳入的map參數裏

firstProductMapper.updateName(map);
String restrString = (String) map.get("results");
