java - REST Jersey 异常 AbstractJAXBProvider

Question

我有这个资源

@Path("customer")
public class Customers

在它里面，我有这个功能:

@Path("signin/{mobileNumber}/{simNumber}/{password}")
    @GET
    @Produces({ MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON })
    @Consumes(MediaType.APPLICATION_FORM_URLENCODED)
    public CustomerImpl signgin(@PathParam("mobileNumber") String mobileNumber,
            @PathParam("simNumber") String simNumber,
            @PathParam("password") String password) {
        // return "dddddddddddddddddddddddddddddddd";
        return CustomerWraper.instance.getOne(1);
    }

当我调用该函数时出现异常，

我正在使用customerWraper:

public enum CustomerWraper {
    instance;
    private Map<Integer, CustomerImpl> customers = new HashMap<Integer, CustomerImpl>();

    public Map<Integer, CustomerImpl> getData() {
        return customers;
    }

    private CustomerWraper() {
        CustomerImpl c = (CustomerImpl)CustomerImpl.getCustomer(1);
        this.customers.put(1, c);
    }

    public CustomerImpl getOne(int ID) {
        CustomerImpl customer = getData().get(ID);
        if (customer == null) {
            //customer = (CustomerImpl) CustomerImpl.getCustomer(ID);
            customer = new CustomerImpl("0999440921", "123", "123");
        }
        return customer;
    }
}

注意:

customerImpl 类是这样的:

@XmlRootElement(name = "customer")
public class CustomerImpl extends com.syriatel.eattel.user.User implements
        Customer {

User 类是抽象的。

异常(exception)的是:(很长，看最后)

这是堆栈跟踪中有趣的一行；

com.syriatel.eattel.user.Customer is an interface, and JAXB can't handle interfaces.

与您发布的内容相比，您的堆栈跟踪清楚地显示了更多的类。请再次检查您的代码。在某个地方，“客户”接口(interface)被直接引用，或者以导致 Jersey 尝试直接启动它的方式引用。

如果可以的话，我建议完全摆脱 Interface，只是暂时这样做，只是为了确保这是真正的罪魁祸首。
