beanName不能爲空

我相當有信心有一些類或jar問題正在進行，但我不清楚看到它是什麼。 beanName錯誤在任何類型的搜索中都沒有提供非常有用的數據。我試圖在Tomcat 8上啓動它，當我得到錯誤。我在休眠5.運行這是我的錯誤：beanName不能爲空

這裏是在data.xml中引用bean：

<bean id="sessionFactory" 
     class="org.springframework.orm.hibernate5.LocalSessionFactoryBean" > 
     <property name="dataSource" ref="${database.dataSource}" /> 
     <property name="annotatedClasses"> 
      <list> 
       <value>com.adilly.giftlist.model.BaseEntity</value> 
       <value>com.adilly.giftlist.model.EmailOptOut</value> 
       <value>com.adilly.giftlist.model.Event</value> 
       <value>com.adilly.giftlist.model.EventComment</value> 
       <value>com.adilly.giftlist.model.EventUser</value> 
       <value>com.adilly.giftlist.model.PersistentLogins</value> 
       <value>com.adilly.giftlist.model.User</value> 
       <value>com.adilly.giftlist.model.WishItem</value> 
       <value>com.adilly.giftlist.model.WishItemComment</value> 
       <value>com.adilly.giftlist.model.WishItemReservation</value> 
      </list> 
     </property> 

     <property name="hibernateProperties"> 
      <props> 
       <prop key="hibernate.dialect">${database.dialect}</prop> 
       <prop key="hibernate.connection.autocommit">true</prop> 
       <prop key="hibernate.connection.autoReconnect">true</prop> 
       <prop key="hibernate.hbm2ddl.auto">update</prop> 
       <prop key="hibernate.show_sql">${database.showSQL}</prop> 
<!-- 
       <prop key="hibernate.current_session_context_class">thread</prop> 
       <prop key="hibernate.transaction.factory_class">org.hibernate.transaction.JDBCTransactionFactory</prop> 
--> 

      </props> 
     </property> 
    </bean>

的問題是，你都指向一個屬性的數據源！

<property name="dataSource" ref="${database.dataSource}" />

您應該創建一個ID爲「datasource」的bean，並將它包含在sessionFactory中！在例子看看：

<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> 
    <property name="driverClassName" value="${jdbc.driverClassName}" /> 
    <property name="url" value="${jdbc.url}"/> 
    <property name="username" value="${jdbc.username}" /> 
    <property name="password" value="${jdbc.password}"/>   
</bean>

然後，在你的sessionFactory，改成這樣：

<property name="dataSource" ref="dataSource" />

看看Spring JDCB Documentation here

因此，在這種應用中，還有其他一些豆類參考像這樣一個屬性，它是$ {database.SOMEITEM}我應該設置這個bean來保存它裏面的所有值以及它們需要指向的位置嗎？ – facon12

問題@ falcon12是來自sessiomFactory的屬性dataSource不希望從外部配置屬性，而是一個Speing bean！你應該像我向你解釋的那樣創建數據源bean。 – BrunoDM

它是有道理的。對於更多的上下文，我繼承了這個應用程序的當前狀態，所以我正在解決它的問題。我被告知它正在運行的狀態，但我很懷疑。我是一個.net開發者，所以豆類有點難以爲我處理。我會通過這個工作並回來接受解決方案，只要給我一點時間。 – facon12
