我java.io.EOFException
在 Android 上使用 Spring REST 模板时收到 's。
堆栈跟踪原因如下所示:

这一切都发生在我的 Xoom 平板电脑上安装的 Android 4.1.2 上。
问题出现又消失。它也不是由长请求触发的。服务器部分在本地网络中的机器上运行。当我尝试通过 运行 API 调用时curl
,它工作得很好。
AuthTokenInterceptor:
@Override
public ClientHttpResponse intercept(HttpRequest request, byte[] data, ClientHttpRequestExecution execution) throws IOException {
HttpHeaders headers = request.getHeaders();
if (!StringUtils.isEmpty(mAuthToken)) {
headers.add((mIsOAuth ? "Authorization" : "authToken"), (mIsOAuth ? "Bearer " : "") + mAuthToken);
}
return execution.execute(request, data);
}
LoggingClientHttpRequestInterceptor:
/** {@inheritDoc} */
@Override
public ClientHttpResponse intercept(HttpRequest httpRequest, byte[] bytes, ClientHttpRequestExecution clientHttpRequestExecution) throws IOException {
Log.d(TAG, "To : " + httpRequest.getURI());
Log.d(TAG, "Method : " + httpRequest.getMethod().name());
Log.d(TAG, "Data : " + new String(bytes));
for (Object key : httpRequest.getHeaders().keySet()) {
Log.d(TAG, "Header <" + key + ">: " + httpRequest.getHeaders().get(key));
}
final ClientHttpResponse response = clientHttpRequestExecution.execute(httpRequest, bytes);
if (response != null) {
Log.d(TAG, "Response: " + response.getStatusCode());
if (response.getBody() != null) {
Log.d(TAG, "Response: " + convertStreamToString(response.getBody()));
}
} else {
Log.d(TAG, "Response: " + response);
}
return response;
}
Rest Template 的配置如下:
final RestTemplate template = new RestTemplate(false);
template.getMessageConverters().add(new MappingJacksonHttpMessageConverter());
template.setRequestFactory(new BufferingClientHttpRequestFactory(template.getRequestFactory()));
ApiUtils.addAuthTokenHeaderToRestTemplate(template, mAuthToken, false);
ApiUtils.addRequestLoggingToRestTemplate(template);
此处崩溃的相关 API 调用在基于 Android 注释的接口中进行了描述:
@Post("/user/memberships")
@Accept(MediaType.APPLICATION_JSON)
CompanyApiResponse saveGroupMembership(UserGroupMembership membership) throws RestClientException;
我尝试过的事情:
- 删除 LoggingInterceptor
- 通过 CURL 调用所有 API 调用
- 删除了调用 BufferingClientHttpRequestFactory -有一点帮助,但错误仍然发生。
- 在 Android 2.3 上测试过 -错误无法重现
我一直在阅读各种论坛帖子,如果 URL 不正确,似乎会出现 EOF 异常,在这种情况下我会仔细检查。
另外值得注意的是,一旦发生 EOF 异常,调用甚至不会到达服务器端。
继续寻找修复的好点在哪里?这是 Android 4.1 带来的不便吗?
在调试这个问题时,我还发现了https://jira.springsource.org/browse/ANDROID-102这使我之前看不到真正的错误(EOF)。
更新:刚刚找到http://code.google.com/p/google-http-java-client/issues/detail?id=116 - 它可能是相关的。
该修复程序也在https://codereview.appspot.com/6225045/中进行了概述-因此它可能已合并为 4.1。
