Getting：java.lang.IllegalStateException：型[java.lang.String]の値を必須の型[javax.sql.DataSource]に変換できません

Question

私はSpring 3.2.13 jarsとibatis 2.3.4.726のバージョンを使用して設定しています

<bean id="commonDataSource" class="org.springframework.jndi.JndiObjectFactoryBean"> 
    <property name="jndiName" value="jdbc/ds_GOLD" /> 
    <property name="defaultObject" value="jdbc/ds_SILVERR" /> 
</bean> 

<bean id="sqlMapClient" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean"> 
    <property name="configLocation"> 
     <value> 
      classpath:com/dav/dao/config/sqlMapConfig.xml 
     </value> 
    </property> 
    <property name="dataSource"> 
     <ref bean="commonDataSource" /> 
    </property> 
    <property name="transactionConfigClass"> 
     <value>com.ibatis.sqlmap.engine.transaction.external.ExternalTransactionConfig 
     </value> 
    </property> 
    <property name="transactionConfigProperties"> 
     <props> 
      <prop key="DefaultAutoCommit">false</prop> 
      <prop key="SetAutoCommitAllowed">false</prop> 
     </props> 
    </property> 
</bean> 

構成は、私にとっては良いようだが、例外 Oを取得：

の下に、私は以下の例外を取得していますなどのdataSource Caused by: java.lang.IllegalStateException: Cannot convert value of type [java.lang.String] to required type [javax.sql.DataSource] for property 'dataSource': no matching editors or conversion strategy found

私のxml春の構成は以下の通りです"jdbc/ds_GOLD"がAppサーバーで設定されていない場合はnly。この場合、defaultObject JNDIが選択されます。 "jdbc/ds_GOLD"がAppサーバーに設定されていると、ログにエラーは表示されません。しかし、フェイルオーバーの場合は動作しません。

Answer 1

defaultObjectをdataSourceへのプロパティ参照として保持しないでください。私は誤ってそれをプロパティ値として設定しました。
