解编组错误:意外元素(uri:url，local:"objectname")。期望元素是<{}objectname>

Question

我使用jaxb2编组器生成类，以便与webservice进行通信。Java类是通过使用一些wsdl文件生成的。

现在一切都好了，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>

我的同学：

@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

• 或者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

请张贴您的ObjectFactory和package-info.java (必须在ObjectFactory旁边生成)。

实际上，您不必通过ObjectFactory创建实例，普通的new构造可以正常工作。) ObjectFactory没有魔法。它主要由JAXB在解编组过程中使用。

ps。请在maven-jaxb2-plugin-related问题上加上maven-jaxb2-plugin标签--这会更快地引起我的注意。

Answer 2

请使用以下注释

@XmlRootElement(name="Customer")

在类的根处，如下所示。由于JAXb不会自动创建@XmlRootElement注释，所以需要手动将该注释放在类的顶部。

Answer 3

如果项目中有多个模块，请检查重复的类名或目录名。

我得到了同样的错误，我能够通过更改我的项目中的包名来解决它。

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两个不同的WSDL，但它们都来自同一个客户机。当我们从WSDL自动生成POJO类时，它为我们创建了文件结构。我注意到，在XML中生成的命名空间对两个模块中生成的XML使用相同的命名空间，而它们应该是不同的(因此产生了堆栈跟踪)。

为了解决这个问题，我所做的就是将目录名更改为更具体的每个模块。
