在Java中将树映射与SOAP一起使用

我试图在SOAP服务的方法中返回树映射，获得以下异常：

为什么它试图序列化一个列表？我可以让它与任何其他SortedMap一起工作吗？

正如@PaulVargas在评论中指出的，JAX-B不直接支持TreeMap

我解决了这个问题，创建了我的TreeMapSerializer来适应这个答案

SortedMap和其他Map实现都不受JAX-B的直接支持。@PaulVargas SortedMap是一个接口，我想你的意思是TreeMap有没有办法手动添加对它们的支持？你能给我们看看你的代码吗？@Santiago我认为这不相关，所以我并没有把它添加到问题中，但这里有一个隐含的片段：它试图序列化一个列表，因为TreeMap的构造函数中有一个列表。
