是否可以使 Map<?, ?> someMethod 与 JAX-B 一起工作？

Question

尝试使用cxf-java2ws-plugin生成Web Service工件时，依次使用JAX-B，我以下面的方式在看起来像这样的方法上获得错误：

  Map<?, ?> myMethod(...);

更改方法签名是最后的手段，所以我正在寻找替代方案。

Caused by: com.sun.xml.bind.v2.runtime.IllegalAnnotationsException: 2 counts of IllegalAnnotationExceptions
java.util.Map is an interface, and JAXB can't handle interfaces.

                at com.company.SomeClass
java.util.Map does not have a no-arg default constructor.

Answer 1

jaxb将允许您拥有类型Map的属性，但不能将其用作根级对象。
