例外: 软件导致连接中止: recv 失败

对于下面这个错误到底意味着什么，我还没有找到一个合适的答案:

java.net.SocketException: Software caused connection abort: recv failed

备注:

  • 此错误不常见且不可预测; 尽管得到此错误意味着以后对 URI 的所有请求也将失败。
  • 唯一可行的解决方案(也只是偶尔可行)是重新启动 Tomcat 和/或实际的计算机(本例中是 Windows)。
  • URI 肯定是可用的(通过请求浏览器执行提取来确认)。

相关守则:

BufferedReader reader;
try {
URL url = new URL(URI);
reader = new BufferedReader(new InputStreamReader(url.openStream())));
} catch( MalformedURLException e ) {
throw new IOException("Expecting a well-formed URL: " + e);
}//end try: Have a stream


String buffer;
StringBuilder result = new StringBuilder();
while( null != (buffer = reader.readLine()) ) {
result.append(buffer);
}//end while: Got the contents.
reader.close();

Are you accessing http data? Can you use the HttpClient library instead of the standard library? The library has more options and will provide better error messages.

The only time I've seen something like this happen is when I have a bad connection, or when somebody is closing the socket that I am using from a different thread context.

This usually means that there was a network error, such as a TCP timeout. I would start by placing a sniffer (wireshark) on the connection to see if you can see any problems. If there is a TCP error, you should be able to see it. Also, you can check your router logs, if this is applicable. If wireless is involved anywhere, that is another source for these kind of errors.

Try adding 'autoReconnect=true' to the jdbc connection string

This will happen from time to time either when a connection times out or when a remote host terminates their connection (closed application, computer shutdown, etc). You can avoid this by managing sockets yourself and handling disconnections in your application via its communications protocol and then calling shutdownInput and shutdownOutput to clear up the session.

Look if you have another service or program running on the http port. It happened to me when I tried to use the port and it was taken by another program.

If you are using Netbeans to manage Tomcat, try to disable HTTP monitor in Tools - Servers

This also happens if your TLS client is unable to be authenticate by the server configured to require client authentication.

I too had this problem. My solution was:

sc.setSoLinger(true, 10);

COPY FROM A WEBSITE -->By using the setSoLinger() method, you can explicitly set a delay before a reset is sent, giving more time for data to be read or send.

Maybe it is not the answer to everybody but to some people.

This error occurs when a connection is closed abruptly (when a TCP connection is reset while there is still data in the send buffer). The condition is very similar to a much more common 'Connection reset by peer'. It can happen sporadically when connecting over the Internet, but also systematically if the timing is right (e.g. with keep-alive connections on localhost).

An HTTP client should just re-open the connection and retry the request. It is important to understand that when a connection is in this state, there is no way out of it other than to close it. Any attempt to send or receive will produce the same error.

Don't use URL.open(), use Apache-Commons HttpClient which has a retry mechanism, connection pooling, keep-alive and many other features.

Sample usage:

HttpClient httpClient = HttpClients.custom()
.setConnectionTimeToLive(20, TimeUnit.SECONDS)
.setMaxConnTotal(400).setMaxConnPerRoute(400)
.setDefaultRequestConfig(RequestConfig.custom()
.setSocketTimeout(30000).setConnectTimeout(5000).build())
.setRetryHandler(new DefaultHttpRequestRetryHandler(5, true))
.build();
// the httpClient should be re-used because it is pooled and thread-safe.


HttpGet request = new HttpGet(uri);
HttpResponse response = httpClient.execute(request);
reader = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
// handle response ...
