Apache CXF实战之三 Map类型绑定

在CXF中，如果Web Service返回类型是Map的时候，比如方法签名如下

?

[java] view plaincopyprint?
  1. @WebMethod??
  2. @WebResult?Map<String,?User>?getUserMap();??

此时如果运行程序会得到类似下面的异常

[java] view plaincopyprint?
  1. ...??
  2. Caused?by:?com.sun.xml.bind.v2.runtime.IllegalAnnotationsException:?2?counts?of?IllegalAnnotationExceptions??

如果把方法签名改为如下时
