Question

在eventuate程序中，低于错误，我怀疑某些依赖项缺失或版本问题。

实际上我跟着https://github.com/eventuate-examples/eventuate-examples-java-spring-todo-list并尝试使用maven构建项目，但它不起作用。

或者如果你们有一个基于'事件驱动'的项目示例，请分享给我。

错误：

Answer 1

我猜你不知何时使用了new（需要MissingApplyEventMethodStrategy）和旧的（不提供MissingApplyEventMethodStrategy）Eventuate库。

特别是0.11.0.RELEASE相当陈旧。尝试升级到最新的0.17.0.RELEASE

获取eventCate程序的noClassDefFoundError
