Question

我正在尝试使用 spring boot 开发 WebService 服务并将其发布到 ServiceMix 中，但我遇到了这样的异常:

这意味着一些注释引用了一个不在类路径中的类，但我怎么知道哪个类被遗漏了？我的 list 标题是:

Answer 1

您的大部分导入都是 resolution:=optional 这意味着您的包可能总是会解析，但您无法保证所需的类在需要时可用。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失的类型。但是，如果您的代码必须存在这些类型，则必须导入这些类型的包。

我建议您从导入中删除 resolution:=optional 并查看情况。由于缺少包的导出商，您可能会遇到解决错误，但这会告诉您包需要什么。
