Java Spring:NPE，同时从XML配置创建bean
我正在使用Java和Spring框架进行应用程序的迁移。 迁移是一大步，libs版本的移动如下：Java Spring:NPE，同时从XML配置创建bean,java,xml,spring,javabeans,Java,Xml,Spring,Javabeans,我正在使用Java和Spring框架进行应用程序的迁移。 迁移是一大步，libs版本的移动如下： Java JDK1.6到JDK11 Spring框架3.2.0至5.3.1 Spring集成3.0.0到5.4.1 弹簧安全3.1.0至5.4.2 我花了一些时间在编译问题上，但现在我在启动应用程序时卡住了 应用程序配置是所有XMLBeans配置（以及spring集成消息传递配置）中的大部分。 在启动和创建bean时，应用程序总是以相同的NullPointerException失败 示例1: 一
- Java JDK1.6到JDK11
- Spring框架3.2.0至5.3.1
- Spring集成3.0.0到5.4.1
- 弹簧安全3.1.0至5.4.2
