Java Spring Web服务客户端故障处理

我编写了一个与UPS Web服务一起使用的Web服务客户端(使用Java Spring和JAXB Marshaller).当我发送有效请求时,一切正常.当我发送无效请求(权重> 150磅)时,UPS Web服务会响应SOAP Fault.客户端应用程序失败了

org.springframework.oxm.UnmarshallingFailureException: JAXB unmarshalling 
exception; nested exception is javax.xml.bind.UnmarshalException: 
unexpected element (uri:"http://schemas.xmlsoap.org/soap/envelope/",local:"Fault").

显然我的程序无法破译Web服务返回的SOAP错误.我写了一个自定义的FaultMessageResolver,但它没有被调用.这是代码：

public class UpsRateClient extends WebServiceGatewaySupport {
    public UpsRateClient(WebServiceMessageFactory messageFactory) {
        super(messageFactory);
        getWebServiceTemplate().setFaultMessageResolver(new UpsFaultMessageResolver());
    }

    public RateResponse getRate(RateRequest rateRequest) {
        return (RateResponse) getWebServiceTemplate().marshalSendAndReceive(rateRequest,new UpsRequestWSMC());
    }
    private class UpsFaultMessageResolver implements FaultMessageResolver {
        public void resolveFault(WebServiceMessage message) throws IOException{
            System.out.println("Inside UpsFaultMessageResolver");   
        }
    }
}

谢谢你的时间！
