我有一个在Tomcat 7 w / MS SQL Server 2008上运行Hibernate 4.2.19的Spring 3.1.2 Web应用程序，我遇到了这个错误：

我的猜测是我没有正确配置entityManagerFactory bean，但我不确定我哪里出错了。

我希望这个例外更具描述性。
调用init方法失败;嵌套异常是javax.persistence.PersistenceException：[PersistenceUnit：GSP]无法构建EntityManagerFactory。
我的JDBC资源在tomcat / conf / context.xml中定义如下：
<Resource name="jdbc/salesvietnamMssqlGspDS"
auth="Container"
factory="org.apache.tomcat.dbcp.dbcp.BasicDataSourceFactory"
driverClassName="com.microsoft.sqlserver.jdbc.SQLServerDriver"
type="javax.sql.DataSource"
maxActive="50"
maxIdle="10"
maxWait="15000"
username="un"
password="pw"
url="jdbc:sqlserver://server\instance:port;databaseName=GSPVN;"
removeAbandoned="true"
removeAbandonedTimeout="30"
logAbandoned="true" />
我尝试重命名此资源，因此无法找到它，但事实并非如此。抛出的异常有更长的堆栈跟踪和更多细节，但最终以相同的根本原因结束：
无法构建EntityManagerFactory
这可能意味着我的资源没有正确定义吗？
答案 0 :(得分：1)
您正在尝试创建两个具有相同ID的bean。这可能会导致entityManager创建失败。
<jee:jndi-lookup id="dataSource" jndi-name="jdbc/salesVietnam" resource-ref="true"
lookup-on-startup="true" />
和
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close">
<property name="driverClassName" value="com.microsoft.sqlserver.jdbc.SQLServerDriver" />
<property name="url" value="jdbc:sqlserver://server\instance:port;databaseName=GSPVN;" />
<property name="username" value="un" />
<property name="password" value="pw" />
</bean>
你也有
<bean id="persistenceAnnotation" class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor" />
如果您可以选择修改XML文件，那么最好使用Annotations将其放入JAVA类中。
