如何获取JAX-WS响应HTTP状态代码 [英] How to get JAX-WS response HTTP status code

问题描述

调用JAX-WS端点时，如何获取HTTP响应代码?

When calling a JAX-WS endpoint, how can I get the HTTP response code?

在下面的示例代码中，当在port.getCustomer(customerID);处调用Web服务时，可能会引发异常，例如401或500.

In the sample code bellow, when calling the web service at port.getCustomer(customerID); an Exception may be thrown, such as 401 or 500.

在这种情况下，如何从HTTP响应中获取HTTP状态代码?

In such cases, how can I get the HTTP status code from the HTTP response?

@Stateless
public class CustomerWSClient {

    @WebServiceRef(wsdlLocation = "/customer.wsdl")
    private CustomerService service;

    public void getCustomer(Integer customerID) throws Exception {
        Customer port = service.getCustomerPort();
        port.getCustomer(customerID); // how to get HTTP status           
    }

}

推荐答案

完成@Praveen答案，您必须将port转换为原始的BindingProvider，然后从上下文中获取值.

Completing @Praveen answer, you have to turn the port into a raw BindingProvider and then get the values from the context.

如果托管的Web服务客户端中发生异常，请不要忘记将事务标记为回滚.

Don't forget that transaction will be marked for rollback if an exception occours in your managed web service client.

@Stateless
public class CustomerWSClient {

    @WebServiceRef(wsdlLocation = "/customer.wsdl")
    private CustomerService service;

    public void getCustomer(Integer customerID) throws Exception {
        Customer port = service.getCustomerPort();
        try {
            port.getCustomer(customerID);  
        } catch(Exception e) {
            throw e;
        } finally {
            // Get the HTTP code here!
            int responseCode = (Integer)((BindingProvider) port).getResponseContext().get(MessageContext.HTTP_RESPONSE_CODE);
        }
    }

}
