java.lang.ArrayStoreException：servicemix 上的 sun.reflect.annotation.TypeNotPresentExceptionProxy

Question

我正在尝试使用 spring boot 开发一个 WebService 服务并在 ServiceMix 中发布它，但是我遇到了这样的异常：

这意味着某些注释正在引用不在类路径中的类，但是我如何知道错过了哪个类？ 我的清单标题是：

您的大部分导入都是resolution:=optional，这意味着您的捆绑包可能总是会解析，但您无法保证需要的类在需要时可用。比如你现在的情况。可选解决方案适用于真正可选的包，并且您的包已准备好处理缺少的类型。但是如果你的代码必须有这些类型，那么这些类型的包的导入是强制性的。

我建议您从导入中删除resolution:=optional，看看情况如何。由于缺少包的导出器，您可能会遇到解决错误，但这会告诉您您的包需要什么。
