遷移，Hibernate的3.6.3-JPA應用到Hibernate 4

Question

你好，我想遷移的Hibernate 3.6.3應用到Hibernate 4，我收到以下錯誤：

Invalid property 'dataSource' of bean class 
[org.springframework.orm.jpa.LocalEntityManagerFactoryBean]: 
Bean property 'dataSource' is not writable or has an invalid 
setter method. Does the parameter type of the setter match the 
return type of the getter? 

我已經看了這個帖子： integrating JPA and SpringIOc

當我使用LocalEntityManagerFactoryBean負責我得到上面提到的錯誤，但是當我使用LocalContainerEntityManagerFactoryBean我創造我的DAO bean時得到一個錯誤。

我認爲這是spring.orm依賴配置的問題，但我不確定，因爲我所做的所有依賴項更改都不起作用。

我在哪裏可以找到Hibernate 4遷移指南，以適應我的JPA，Hibernate 3.6.3和Spring應用程序？

按照Documentation

This EntityManagerFactory bootstrap is appropriate for standalone applications which solely use JPA for data access. If you want to set up your persistence provider for an external DataSource and/or for global transactions which span multiple resources, you will need to either deploy it into a full Java EE 5 application server and access the deployed EntityManagerFactory via JNDI, or use Spring's LocalContainerEntityManagerFactoryBean with appropriate configuration for local setup according to JPA's container contract.

這意味着你可能需要使用LocalContainerEntityManagerFactoryBean代替LocalEntityManagerFactoryBean

<bean id="entityManager" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"> 
    <property name="dataSource" ref="myDataSource" /> 
    .... 
    .... 
</bean>
