我正在使用CXF从WSDL开发Web服务，我希望能够使用JUnit运行测试样本请求。
My Test类创建一个模拟服务器，然后充当客户端来测试服务器。
我不明白为什么我会继续Unmarshalling Error: unexpected element例外。
我将问题分解为一个最小的项目，但即便如此也无济于事。我确信问题来自于我做过的一些愚蠢的错误......已经有两天了，我找不到它......
错误消息为：org.apache.cxf.interceptor.Fault: Unmarshalling Error: unexpected element (uri:"http://my.project.service", local:"myProperty"). Expected elements are <{http://my.project.service}myObject>
就好像它期待myObject内的其他myObject元素...所有东西都是使用CXF生成的，为什么它不能解组几毫秒之前它只是编组的东西？
我试过soap 1.1 / 1.2，我尝试了不同版本的CXF高达3.0.5，我尝试使用命名空间，但总是出现同样的错误。
以下是重现错误的最小项目的全部内容：

抱歉模糊不清，当我知道更多时，我愿意改善这个问题......
感谢您的时间。
编辑2015-08-18 ：在wsdl中，如果我将元素MyOperationRequest重命名为MyOperation（操作名称），CXF将启用包装器风格和测试将通过。
我的问题是我无法改变wsdl，我需要让关闭包装器样式的模拟服务。
编辑2015-08-21 ：将wsdl样式设置为rpc可以绕过问题，但在我的情况下这个解决方案是不可接受的。也许我可以改变wsdl，但请求和响应结构不能改变。
我正在删除我的解决方案（将样式设置为rpc）。
答案 0 :(得分：0)
我认为错误发生在wsdl中，这是我的理解：
包装器样式假定操作名称与包装器元素名称匹配，但在我的wsdl中不是这样。
非包装样式假定wsdl样式为rpc，但在我的wsdl中却不是这样。
为了与两种包装样式中的一种兼容，我认为我必须改变wsdl。将wsdl样式设置为rpc是不可接受的，因为响应的结构会发生变化。
所以我的解决方案是更改操作的名称，我需要在Java中更新实现方法的名称，但请求和响应消息将保持不变。
