This SQL map does not contain a MappedStatement Named错误

1. sqlmap没有填写命名空间名称时：

<sqlMap namespace="" xmlns="http://ibatis.apache.org/mapping" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

确保调用的名称和sqlmap中的id保持一致，最好手工赋值一下，有时候手敲难免处错误

2. sqlmap填写了命名空间名称时：

<sqlMap namespace="WorkTask" xmlns="http://ibatis.apache.org/mapping" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

此时调用时，需要在前面加上命名空间名称.Id名称

var taskAllocationList = sqlMapper.QueryForList<TaskAllocation>("WorkTask.FindTaskAllocationByInputId", inputId);

SqlMap中可加可不加  命名空间.

3.Ibatis常用语法

<select id="SearchApplyDataIndexBackByIds" parameterClass="int" resultMap="ApplyDataIndexResultMap">
      SELECT * FROM DC_APPLYDATAINDEXBACK
      <dynamic prepend="WHERE">
        <isNotEmpty prepend="AND" property="ApplyIndexIds">
          APPLYINDEXID IN
          <iterate property="ApplyIndexIds" open="(" close=")" conjunction=",">
            $ApplyIndexIds[]$
          </iterate>
        </isNotEmpty>
      </dynamic>
    </select>

  <select id="SearchApplyIndexCategorys" parameterClass="map" resultMap="ApplyIndexCategoryResultMap">
      SELECT * FROM(
      select t.*,ROWNUM as RN From (
      Select * FROM DC_APPLYINDEXCATEGORY
      <dynamic prepend="WHERE">
        <isNotEmpty prepend="AND" property="ApplyId">
          ApplyId = #ApplyId#
        </isNotEmpty>

        <isNotEmpty prepend="AND" property="ContainsStatus">
          ApplyStatus IN
          <iterate property="ContainsStatus" open="(" close=")" conjunction=",">
            $ContainsStatus[]$
          </iterate>
        </isNotEmpty>
      </dynamic>
      ORDER BY ApplyId DESC) T)Q
      WHERE Q.RN &gt;#Start# AND Q.RN &lt;= #End#
    </select>
