当我尝试解组 WebServiceResponse 时出现解组错误

问题描述 投票：0回答：1

我收到来自第 3 方 API 的响应，该响应给我一个解组 xml 响应的错误，类似于：

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ns2:webServiceResponse
    xmlns="http://ws.services.company.com"
    xmlns:ns2="http://rest.ws.services.company.com">
    <ns2:result>
        <success>true</success>
        <id>7054986</id>
    </ns2:result>
</ns2:webServiceResponse>

通常我会使用这样的 xml 响应来测试我的 Java 代码，并且获得成功：

<webServiceResponse xmlns="http://ws.services.company.com">
  <result>
    <success>true</success>
    <id>1</id>
  </result>
</webServiceResponse>

在 Java 中，我一直在使用以下 xsd 文件创建相应的 XML 数据类。

任何人都可以帮忙解决这个问题吗？

我认为它无法将响应名称空间与 ns2 关联起来，ns2 与 uri 开头关联为 

rest
。但我无法在 xsd 文件上执行此操作以与 ns2 关联，因为它总是给出错误。

XSD 中的目标命名空间，因此在 Java 生成的代码中是 

targetNamespace="http://ws.services.company.com"
，但您会在 
webServiceResponse
命名空间中收到 
http://rest.ws.services.company.com
。

这就是解组器抱怨没有收到预期元素之一的原因

您的 XSD 是您自己创建的还是由其他人发送的？无论如何，要使其正常工作，您应该根据预期更改 

targetNamespace
（其中包含 
rest
前缀）。
