昆德拉:持久性配置cassandra+eclipse+kundera中的错误

Question

我对我的cassandra+kundera+eclipse项目的持久性有一个问题。报告的错误如下：

Log4j:没有为记录器(com.impetus.kundera.KunderaPersistence)找到任何附加程序。log4j :警告请正确初始化log4j系统。Log4j:警告参见http://logging.apache.org/log4j/1.2/faq.html#noconfig以获得更多信息。线程"main“com.impetus.kundera.loader.PersistenceLoaderException: com.impetus.kundera.utils.InvalidConfigurationException:中的异常无法在com.impetus.kundera.configure.PersistenceUnitConfiguration.configure(PersistenceUnitConfiguration.java:100) at com.impetus.kundera.configure.PersistenceUnitConfiguration.configure(PersistenceUnitConfiguration.java:100) at com.impetus.kundera.configure.Configurator.configure(Configurator.java:65) at com.impetus.kundera.KunderaPersistence.initializeKundera(KunderaPersistence.java:109) at com.impetus.kundera.KunderaPersistence.createEntityManagerFactory的类路径中找到任何META/sistence.xml文件。( javax.persistence.Persistence.createEntityManagerFactory(Unknown Source) at javax.persistence.Persistence.createEntityManagerFactory(Unknown Source) at controlador.Conetor.main(Conetor.java:17)引起的: com.impetus.kundera.utils.InvalidConfigurationException:在com.impetus.kundera.configure.PersistenceUnitConfiguration.findPersistenceMetadatas(PersistenceUnitConfiguration.java:132) at com.impetus.kundera.configure.PersistenceUnitConfiguration.configure(PersistenceUnitConfiguration.java:83) .6的类路径中找不到任何META/sistence.xml文件。

请把你的persistence.xml放在下面的路径上。它应该解决这个错误。src/main/resources/META-INF/persistence.xml
