解组错误：意外元素（uri：url，本地：“objectname”）。预期的元素是 <{}objectname>

Question

我正在使用 jaxb2-marshaller 生成类以与 web 服务进行通信。 Java 类是使用一些 wsdl 文件生成的。

现在一切正常，但是当我尝试使用一些生成的类时，我得到了这个解组错误，尽管我使用了生成的 ObjectFactory 类。

一些堆栈：

 org.springframework.ws.soap.client.SoapFaultClientException: Unmarshalling Error: unexpected element (uri:"http://xxxxxxxxx", local:"customer"). Expected elements are <{}customer>

我的课：

 @Service
public class CustomerService {

    @Autowired
    private WebServiceTemplate customerDaoTemplate;

    private ObjectFactory customerObjectFactory;

    public CustomerService() {
        customerObjectFactory = new ObjectFactory();
    }

    public boolean createCustomer(Customer c)
    {
        System.out.println("CREATING CUSTOMER");
        einvoice.proxy.customerdaoservice.Customer customer = customerObjectFactory.createCustomer();
        customer.setConnectionURL("test");
        customer.setUid("testuid");
        customer.setName("KorneelTest");

        Create create = customerObjectFactory.createCreate();
        create.setCustomer(customer);

        try
        {
            customerDaoTemplate.marshalSendAndReceive(customerObjectFactory.createCreate(create));
            return true;
        }
        catch(Exception ex)
        {
            ex.printStackTrace();
            return false;
        }
    }

显示此错误的是 createCustomer() 方法。

Answer 1

• 您的原始架构没有正确的目标命名空间。
• 或者你不知何故错过了 package-info.java

请发布您的 ObjectFactory 和 package-info.java （必须在 ObjectFactory 旁边生成）。

您实际上不必通过 ObjectFactory 创建实例，正常 new 构造工作正常。 :) ObjectFactory 没有魔法。它主要由 JAXB 在解组期间使用。

附言。请将 maven-jaxb2-plugin 相关问题标记为 maven-jaxb2-plugin 标记 - 这会更快引起我的注意。

Answer 2

如果您的项目中有超过 1 个模块，请检查是否有重复的类名或目录名。

我遇到了同样的错误，我可以通过更改项目中的包名称来解决它。

我的项目中有两个模块具有相同的目录结构 module/src/main/java/com/example/directory/path

我们有两个不同的端点和 2 个不同的 WSDL，但它们都来自同一个客户端。当我们从 WSDL 自动生成 POJO 类时，它会为我们创建文件结构。我注意到 XML 中生成的名称空间对两个模块中生成的 XML 使用相同的名称空间，而它们本应不同（因此堆栈跟踪）。

为了解决这个问题，我所做的只是更改目录名称，使每个模块更具体。
