我试图在这里关注Oleg的演示：https://www.youtube.com/watch?v=F98NLule18I&t=1909s
我从https://github.com/olegz/si-demo
取出了他的si-demo但是在Nifi 1.6.0中，当SpringContextProcessor与si-demo类路径和toNifiOnly.xml混淆时，处理器会抛出InvocationTargetException，并且处理器将无法正确初始化！
是否有其他演示或示例为Nifi创建弹簧组件？或者如何解决这个问题？
以下是日志文件中的错误消息：

答案 0 :(得分：0)
我后来发现有必要将所有xml文件复制到deps文件夹以让它运行！
