我已经实现了一个CXF restful webservice。Error调用 web服务时抛出一些没有默认构造函数的对象。
错误：

但现在我也在其中创建了默认结构。即Training，但这些变化并没有反映出来，因为我仍然面临同样的问题。
所以我有一个疑问，是否曾经webservice创建过最初的 bean 结构，如果我们更改了它，那么是否需要进行任何其他更改？
我找到了一个解决方案链接，
When the second generation happens, the ObjectFactory is overwritten.
The new file does not contain references to the classes from the first
generation and the JAXB runtime cannot configure itself properly.
但我是新手。我无法理解这些术语wsimport，xjc我该如何执行它？
