Spring 无法从类路径资源分析持久性单元
Spring 无法从类路径资源分析持久性单元,spring,hibernate,jpa,Spring,Hibernate,Jpa,因此，我在运行实现JPA（或应该实现…）的Spring WS应用程序时遇到了这个问题。我在运行WS时遇到问题，我的Spring上下文似乎找不到文件persistence.xml，我可以相信，因为我在模板中没有生成META-INF文件夹（这是带有原型org.springframework.ws的Maven项目模板）我已经手动创建了META-INF。 以下是HTTP 500： org.springframework.beans.factory.BeanCreationException: Erro

src/main/webapp/META-INF/persistence.xml有人能告诉我我缺少什么吗？检查生成的jar和war文件。webapp中的内容将存储在war文件中。war文件的META-INF目录不在webapp的类路径中。请将META-INF目录存储在src/main/resources下，以便它最终位于webapp的WEB-INF/classes目录中，或存储在WEB-INF/lib中生成的jar文件中。检查生成的jar和war文件。webapp中的内容将存储在war文件中。war文件的META-INF目录不在webapp的类路径中。请将META-INF目录存储在src/main/resources下，以便其最终位于ebapp，或存储在WEB-INF/lib中生成的jar文件中。您只在类路径后添加*如下：
