处理android中RestClient调用的连接和读取超时

Question

我有一个RestService接口,有许多休息调用,我在整个应用程序中使用它.

我正在为处理connection和设置超时read-timeouts

ClientHttpRequestFactory httpFactory = myRestService.getRestTemplate().getRequestFactory();
    if(httpFactory!=null)
    {
        if(httpFactory instanceof SimpleClientHttpRequestFactory)
        {
            ((SimpleClientHttpRequestFactory)httpFactory).setConnectTimeout(10*1000);
            ((SimpleClientHttpRequestFactory)httpFactory).setReadTimeout(30*1000);
        }
        else if(httpFactory instanceof HttpComponentsClientHttpRequestFactory)
        {
            ((HttpComponentsClientHttpRequestFactory)httpFactory).setConnectTimeout(10*1000);
            ((HttpComponentsClientHttpRequestFactory)httpFactory).setReadTimeout(30*1000);
        }
    }

但我坚持处理超时情况.我想过使用这种方法但是当休息调用失败时它不会进入这个循环.

myRestService.getRestTemplate().setErrorHandler(new ResponseErrorHandler() 
    {
        @Override
        public boolean hasError(ClientHttpResponse paramClientHttpResponse) throws IOException 
        {
            Log.e(TAG, paramClientHttpResponse==null?"Null response" : ("Has Error : " + paramClientHttpResponse.getStatusText()+" , status code : "+paramClientHttpResponse.getStatusCode()));

            return false;
        }
        @Override
        public void handleError(ClientHttpResponse paramClientHttpResponse) throws IOException 
        {
            Log.e(TAG, paramClientHttpResponse==null?"Null response":("Handle Error : " + paramClientHttpResponse.getStatusText()+" , status code : "+paramClientHttpResponse.getStatusCode()));
        }
    });

任何人都可以帮我这个..!？

Answer 1

ErrorHandlers无法涵盖超时,错误网关,未找到主机以及其他套接字异常.ErrorHandlers的目标是在ResponseErrorHandler的方法签名中查找现有Response中的错误.

所有套接字异常都抛出RestClientException,并且必须在每个RestTemplate操作中捕获,例如try ... catch块中的getForObject().

try {
    repr = myRestService.getRestTemplate().getForObject(url, responseType, vars);
} catch (RestClientException e) {
    //Further exception processing, forming negative response should be here
}

希望,这有帮助.
