Java ibatis配置問題導致Myeclipse啟動web專案失敗

    最近，除錯一web專案，由於人員流動或時間問題出現web專案開發中Java ibatis配置問題導致Myeclipse啟動web專案失敗。
    Myeclipse中使用其自帶的tomcat進行run指定的web工程報錯，報錯資訊如下（出於保密及問題說明，報錯資訊我做了調整）：

     透過以上報錯資訊，分析得出專案配置檔案spring-mybatis.xml中定義的bean名字為accountServiceImpl所依賴的bean名字為accountDao的xml配置檔案AdminParaMapper.xml
中有語法錯誤：Parsing error was found in mapping #{}.  Check syntax #{property|(expression), var1=value1, var2=value2, ...} ，導致accountDao的bean無法建立，
引起accountServiceImpl在 Injection資源accountDao的過程中失敗，從而導致sqlSessionFactory建立失敗，web專案載入失敗。
    排查AdminParaMapper.xml檔案，發下以下配置有問題（紅色部分是原始碼，我已經註釋，綠色程式碼是改正後的程式碼）：
<update id="updateReleaseByM_flag" parameterType="string">
   <!-- update adminpara set paravalue=#{} -->
   update adminpara set paravalue=#{paraValue}

    按照如上分析結果改正配置後，專案啟動過程中不再報錯得以成功載入。
