Error creating bean with name 'entityManagerFactoryBean'

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
