Bean更改不反映在CXF Restful webservice上

我已经实施了CXF restful webservice。在调用webservice时，有一些没有默认构造函数的对象正在抛出Error。

错误：

但是现在我也在其中创建了默认结构。即Training，但这些变化并未反映，因为我仍面临同样的问题。

所以我怀疑是否使用最初的bean结构创建了一次webservice，如果我们更改了它，那么还需要进行其他更改吗？

我找到了一个解决方案link，

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。我无法理解像wsimport和xjc这样的术语，我怎么能执行它？

1 个答案:

答案 0 :(得分：0)

借助此注释@XmlSeeAlso({ Training.class})，JAXB实现将能够正确绑定Training并对其进行修改。
