Parsed configuration file class path resource Configuration.xml

最近開發項目遇到一個小的問題，困擾了我好大一會時間，現象是項目啓動的過程中控制檯一直輸出mybatis的配置文件，但是一直沒有結束，不停的輸出，導致項目無法正常啓動成功！

搞的我頭大，問題在自己剛增加的代碼有關係，因爲昨天還正常啓動，今天改了點東西就這樣了，經過仔細檢查發現問題。

<resultMap id="queryEquBaseInfoResultMap" type="map">
        <id property="id" column="ID"/>
        <result property="assetNumber" column="ASSET_NUMBER"/>
        <result property="depreciationPeriod" column="DEPRECIATION_PERIOD"/>
        <result property="methodDepreciationId" column="METHOD_DEPRECIATION_ID"/>
        <association property="methodDepreciationName" javaType="map">
        <result property="text" column="METHOD_DEPRECIATION_ID"/>
        <result property="value" column="METHOD_DEPRECIATION_NAME"/>
        </association>
</resultMap>
<select id="queryEquBaseInfoById" parameterType="java.lang.String" resultType="queryEquBaseInfoResultMap">
..........
........
</select>

大家仔細看我上面的mybatis配置有什麼問題？對了，問題就出現在resultType，因爲queryEquBaseInfoResultMap是我自定義的一個集合對象，必須要使用resultMap纔可以！
下面的纔是正確的代碼：

<select id="queryEquBaseInfoById" parameterType="java.lang.String" resultMap="queryEquBaseInfoResultMap">

總結：resultType 和 parameterType都可以直接定義成map，表示輸出和輸入的對象全部集合對象，這個沒有問題，但一旦我們對返回的集合對象進行二次封裝的時候，就必須改成resultMap，可能是因爲mybatis在解析的時候，發現如果是resultType的話，自然認爲是一種常見的類型或者是自己定義的java實體，不會去找配置文件裏的對象吧！
以前面試的時候也有面試官問過這類問題，resultType和resultMap有什麼區別，以前用mybatis也沒在意這種情況，這種寫法也不多見，記錄下來這樣的小問題，下次遇到面試的話，直接可以甩給面試官！
