Java JPA实体解析错误
自从将我的JavaFX项目转换为Maven项目以来，我再也无法访问实体Java JPA实体解析错误,java,web-services,jpa,jax-ws,Java,Web Services,Jpa,Jax Ws,自从将我的JavaFX项目转换为Maven项目以来，我再也无法访问实体BenutzerKonversation。我还收到一条错误消息，当有2个或更多主键时，需要注释@IdClass。在添加注释并创建所需的类BenutzerKonversationId之后，我得到了一个ParseError 经过几次测试，我可以肯定地说它与实体BenutzerKonversation有关。我的实体是WebService（JAX-WS）的一部分。返回实体时，会发生ParseError。返回前实体的输出正确且包含预期值

问题是，我的DTO（数据传输对象）不完整。我意识到，我设置了一个空的“BenutzerKonversation”列表，并试图将不完整的列表返回给客户，这就是问题出现的原因。检查您的eclipselink版本？我使用此依赖项：org.eclipse.persistence eclipselink 2.6.4
同时，我尝试了实体注释的一些附加属性，如fetch=FetchType.EAGER
，但它没有解决问题，也没有添加DTO。
