Question

私はtomcat6.0でJava Webを実行します。私は時間のこの問題を見つけた！

マイapplicationContextCache.xml

<bean id="CaseCache" class="com.aboveE.tpcPo.service.CacheService"> 
    <property name="caseDAO" ref="CaseDAO"/> 
    <property name="offDocDAO" ref="OffDocDAO"/> 
    <property name="caseQueryMap" ref="caseQueryCache" /> 
    <property name="officialQueryMap" ref="officialQueryCache" />

マイapplicationContextDao.xml

<bean id="CaseDAO" 
    class="com.aboveE.tpcPo.dao.CaseDAO"> 
    <property name="sessionFactory">

    </property> 
</bean> 

I'haveは既にGoogleに多くの研究を行って、私は私の問題を解決することはできません。 ..

誰かが私を助けることができます:(

Answer 1

あなたのDAOに問題があるようです。初期化（コンストラクタ/初期化ブロック内、その内部またはその親内部）の読み込み中に問題が発生します。 なぜそれをデバッグしないのですか？

Answer 2

エラーメッセージは、以下に要約：

Error creating bean with name 'CaseDAO' defined in file：

問題がCaseDAO豆です。

Instantiation of bean failed; nested exception is java.lang.ExceptionInInitializerError：

問題はコンストラクタです。

次に該当するかどうかを確認することができます。

• com.aboveE.tpcPo.dao.CaseDAOは、引数なしのコンストラクタを持っていますか？
• コンストラクタはアクセス可能です（つまり、プライベートでも保護されていなくても、Springはこれらのコンストラクタをアクセス可能にしようとします）。
• コンストラクタで例外がスローされましたか？
• com.aboveE.tpcPo.dao.CaseDAOは抽象クラスですか？
