cxf客戶端中的ResponseExceptionMapper

Question

我正在嘗試為我的cxf客戶端使用ResponseExceptionMapper類來處理異常。

ExceptionHandlingCode：

public class MyServiceRestExceptionMapper implements ResponseExceptionMapper<Exception> {


private static final Logger LOGGER = LoggerFactory.getLogger(MyServiceRestExceptionMapper .class);

public MyServiceRestExceptionMapper () {
}

@Override
public Exception fromResponse(Response response) {

    LOGGER.info("Executing MyServiceRestExceptionMapper class");

    Response.Status status = Response.Status.fromStatusCode(response.getStatus());

    LOGGER.info("Status: ", status.getStatusCode());

    switch (status) {

        case BAD_REQUEST:
            throw new InvalidServiceRequestException(response.getHeaderString("exception"));

        case UNAUTHORIZED:
            throw new AuthorizationException(response.getHeaderString("exception"));

        case FORBIDDEN:
            throw new  AuthorizationException(response.getHeaderString("exception"));

        case NOT_FOUND:
            throw new
                    EmptyResultDataAccessException(response.getHeaderString("exception"));

        default:
            throw new InvalidServiceRequestException(response.getHeaderString("exception"));

    }

}

}

CXF客戶端代碼：

String url1= 
WebClient client = createWebClient(url1).path(/document);
client.headers(someHeaders);
Response response = client.post(byteArry);

對於成功方案，我得到正確的響應代碼200，但是對於失敗方案，我從未得到響應代碼。

還有一種更好的方法來處理cxf客戶端中的異常。

有人可以幫忙嗎？

您如何將ResponseExceptionMapper注冊到WebClient？

你需要這樣的東西

List<Object> providers = new ArrayList<Object>();
providers.add(new MyServiceRestExceptionMapper() 
WebClient client = WebClient.create(url, providers);

我建議使用WebApplicationException不是Exception因為如果未注冊ResponseExceptionMapper則默認行為將引發此類異常。 同樣，返回異常，不要拋出該異常。 異常映射器應如下所示。

public class MyServiceRestExceptionMapper implements ResponseExceptionMapper<WebApplicationException>

    public MyServiceRestExceptionMapper () {
    }

    @Override
    public WebApplicationException fromResponse(Response response) {
         //Create your custom exception with status code
         WebApplicationException ex = ...

         return ex;
    }
}
