Error creating bean with name 'entityManagerFactoryBean'

Question

使用maven+jetty,jetty启动就报如下异常.奖dataSource注掉则能够启动.
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'datasourceServiceConfig': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.xzsoft.hfms.persistence.JpaDatasourceDao com.xzsoft.hfms.service.internal.DatasourceServiceConfig.datasourceRep; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'JpaDatasourceDao': Injection of persistence dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactoryBean' defined in URL [jar:file:/E:/.m2/repository/com/xzsoft/hfms/hfms-persistence/1.0-SNAPSHOT/hfms-persistence-1.0-SNAPSHOT.jar!/persistence-config.xml]: Invocation of init method failed; nested exception is java.lang.NullPointerException

Answer 1

<context:component-scan base-package="你的包名" />加上上面这句代码，你用了annotation事务，没注册

Answer 2

我这问题关注的人真少啊，感谢您的参与。<context:component-scan base-package="你的包名" />
这句有，注上的原因是查找问题在那个位置。

Answer 3

问题已解决。问题主要在这个文件persistence-config.xml]: Invocation of init method failed;
经过测试观察出只要加载dataSource就报错.不运行整个maven项目，只做jU测试提示WARN ettingsFactory:140 - Could not obtain connection metadata。由此判断oracle驱动方面的问题机率比较大。在网上下载了一个较新的版本，OK了。我原来使用的驱动是从我目前安装的数据库中考出来的，真不明白为什么不好使。（我现在用的9.2.0.1.0）察看oracle版本信息.jar文件\META-INF\MANIFEST.MF。
好用的驱动版本信息如下：
Specification-Version:  Oracle JDBC Driver version - "10.2.0.1.0"
Implementation-Version: Oracle JDBC Driver version - "10.2.0.1.0"
Implementation-Vendor:  Oracle Corporation
