Camel-Blueprint無法將值org.springframework.orm.hibernate4.LocalSessionFactoryBean轉換爲類型org.hibernate.SessionFactory

我正在使用駱駝藍圖並面臨着hibernate組件的問題。這個例子在春季，但沒有藍圖工作正常JBoss的保險絲6.3V，Camel-Blueprint無法將值org.springframework.orm.hibernate4.LocalSessionFactoryBean轉換爲類型org.hibernate.SessionFactory

所提供的例子是在春季和工作正常，但在藍圖任何例子將有助於 http://camel.apache.org/hibernate-example.html

錯誤： org.osgi .service.blueprint.container.ComponentDefinitionException：錯誤設置屬性：PropertyDescriptor引起：java.lang.Exception：無法將值[email protected]063轉換爲在org.apache處鍵入org.hibernate.SessionFactory .aries.blueprint.container.AggregateConverter.convert（AggregateConverter.java:184）

記住一兩件事。 org.springframework.orm.hibernate4.LocalSessionFactoryBean是Spring的工廠bean當用作<bean>時，它給你一種間接的方式 - 不是直接使用class作爲bean，而是調用getObject()，返回的對象是你的<bean>。

另一件事是Spring爲所有實現了InitializingBean的bean（或工廠bean）自動調用afterPropertiesSet()。

所以不是：

<bean class="org.springframework.orm.hibernate4.LocalSessionFactoryBean" 
     id="mysessionFactory">

使用：

所有感謝您的答覆的

<bean id="mysessionFactory" factory-ref="mysessionFactoryFactory" 
     factory-method="getObject" /> 

<bean class="org.springframework.orm.hibernate4.LocalSessionFactoryBean" 
     id="mysessionFactoryFactory" init-method="afterPropertiesSet"> 
...

第一。這是我學到的新東西。上述更改後，我越來越期待org.osgi.service.blueprint.container.ComponentDefinitionException：無法實例化組件：java.lang.NullPointerException \t at org.apache.aries.blueprint.container.BeanRecipe.getInitMethod（BeanRecipe。 java：619） –

對不起 - 我從頭開始寫 - init-method應該添加到id =「mysessionFactoryFactory」的bean，而不是id =「mysessionFactory」的bean，因爲它應該被調用'hibernate4.LocalSessionFactoryBean'本身，而不是工廠的返回對象（我希望聽起來很清楚;） –

Camel-Blueprint無法將值org.springframework.orm.hibernate4.LocalSessionFactoryBean轉換爲類型org.hibernate.SessionFactory
