Spring 运行时错误 - 设置构造函数参数时无法解析对 bean 'entityManagerFactory' 的引用

Question

我继承了一个需要 JDK 7 的遗留 Java 应用程序。

该应用程序将编译，但我收到运行时错误，看起来像 Hibernate entityManagerFactory 问题。

奇怪的是这个应用程序可以在另一台开发人员的机器上运行。 他甚至给我发了他的 Tomcat 目录，我已经在 Mac 和 Ubuntu 机器上试过了。 无论我在哪里运行它，运行时错误仍然存​​在。

我认为问题是 entityManagerFactory 类中的一个 init 方法，

Cannot resolve reference to bean 'entityManagerFactory' while setting constructor argument; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in de.geoinfoffm.registry.persistence.PersistenceConfiguration: Invocation of init method failed; nested exception is java.lang.NullPointerException

更新 - 问题似乎是找不到此项目的基本包。

处理获取基础包的类——getBasePackages()当然，我不知道为什么这个项目没有在我的开发实例上找到基础包。

Answer 1

你有一个嵌套的 NullPointerException 看起来像你的 PersistenceConfiguration 类

Error creating bean with name 'entityManagerFactory' defined in de.geoinfoffm.registry.persistence.PersistenceConfiguration: Invocation of init method failed; nested exception is java.lang.NullPointerException

如果 NPE 的来源不明显，请考虑发布您的代码。

Answer 2

现有代码和处理字符串数组存在问题。

Spring 或 Hibernate 或 pom 文件配置没有任何问题。
