jaxb - 是否可以使 Map someMethod 与 JAX-B 一起工作？

Question

当尝试使用 cxf-java2ws-plugin 生成 Web 服务工件时，它又使用 JAX-B，我在如下所示的方法中收到以下错误:

  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.
        this problem is related to the following location:
                at java.util.Map
                at private java.util.Map com.company.SomeClass.arg2
                at com.company.SomeClass
java.util.Map does not have a no-arg default constructor.
        this problem is related to the following location:
                at java.util.Map
                at private java.util.Map 

Answer 1

JAXB 将允许您拥有 Map 类型的属性，但不能将其用作根级别对象。
