在Mybatis中，返回的型別寫成resultMap="int"，例如

  <select id="getMessageTimes" resultMap="int" parameterType="com.bojia.fund.bean.Message">
   select count(1) as cconut from smart_message where protocolno=#{protocolno} 
          <![CDATA[ DATE_FORMAT(create_time,'%Y%m%d')= to_date(#{createtime,jdbcType=DATE},'yyyyMMdd')]]>
          and type=#{type} and status=#{status}
   </select>
 

訪問頁面就會報錯，錯誤資訊如下：

org.apache.ibatis.builder.IncompleteElementException: Could not find result map com.bojia.fund.dao.db1.MessageDao.int
	at org.apache.ibatis.builder.MapperBuilderAssistant.getStatementResultMaps(MapperBuilderAssistant.java:346)

現在寫成

 <select id="getMessageTimes" resultType="java.lang.Integer" parameterType="com.bojia.fund.bean.Message">
   select count(1) as cconut from smart_message where protocolno=#{protocolno} 
          <![CDATA[ DATE_FORMAT(create_time,'%Y%m%d')= to_date(#{createtime,jdbcType=DATE},'yyyyMMdd')]]>
          and type=#{type} and status=#{status}
   </select>
  
 

或者寫成

resultType="int"

就不會報錯了
