引起的mybatis異常：元素內容必須由格式正確的字符數據或標記組成

<select id="qryEffSubsUppInstBySubsId"  resultType="com.ztesoft.zsmart.bss.iot.common.dto.SubsUppInst">

        SELECT SUBS_UPP_INST_ID,SUBS_ID,PRICE_PLAN_ID,CREATED_DATE,EFF_DATE,
            EXP_DATE,UPDATE_DATE,STATE,STATE_DATE,PROD_ID,PARENT_SUBS_UPP_INST_ID,
            COMPLETED_DATE,NEED_UPLOAD,PACKAGE_FLAG,AGM_EXP_DATE,SP_ID
            FROM SUBS_UPP_INST WHERE SUBS_ID = #{subsId} 
            AND STATE = 'A'
            AND EFF_DATE <= SYSDATE  AND (EXP_DATE IS NULL OR EXP_DATE > SYSDATE)
            <if test="spId != null">
                 AND SP_ID = #{spId}
            </if>
</select>

錯誤原因：mybatis查詢的時候，需要用到運算符 小於號：< 和 大於號： >，在mybatis配置文件裏面，這種會被認爲是標籤，所以解析錯誤.

解決方法,用

<select id="qryEffSubsUppInstBySubsId"  resultType="com.ztesoft.zsmart.bss.iot.common.dto.SubsUppInst">

        SELECT SUBS_UPP_INST_ID,SUBS_ID,PRICE_PLAN_ID,CREATED_DATE,EFF_DATE,
            EXP_DATE,UPDATE_DATE,STATE,STATE_DATE,PROD_ID,PARENT_SUBS_UPP_INST_ID,
            COMPLETED_DATE,NEED_UPLOAD,PACKAGE_FLAG,AGM_EXP_DATE,SP_ID
            FROM SUBS_UPP_INST WHERE SUBS_ID = #{subsId} 
            AND STATE = 'A'
            <![CDATA[AND EFF_DATE <= SYSDATE  AND (EXP_DATE IS NULL OR EXP_DATE > SYSDATE)]]>
            <if test="spId != null">
                 AND SP_ID = #{spId}
            </if>
</select>
