CodePudding user response:

Two server upload files to this error, change machine code is no problem, also think impassability,

CodePudding user response:

Using TCP short link is invalid,
//the last solution is to the client and the server unified using TCP short connection
Httppost. SetProtocolVersion (HttpVersion. HTTP_1_0);
Httppost. AddHeader (HTTP. CONN_DIRECTIVE, HTTP. CONN_CLOSE);

CodePudding user response:

This file upload is HTTP, you most likely feel file is too big lead to HTTP transmission timeout; You look at how your HTTP call a timeout value is set, the value in the HTTP transmission time is not connection timeout, values change bigger,

CodePudding user response:

The following method is invalid
The browser sends a request to the servlet, the servlet processing time is too long, so lead to chrome ERR_CONNECTION_RESET mistakes
Solution:
In the corresponding servlet execution finally add a code:
Thread. CurrentThread (). The join ();
Said must finish after the carrying out of the current thread to return to the page to the browser,

CodePudding user response:

Link time change again big also invalid
Int timeout=60;//this should make it long point
RequestConfig defaultRequestConfig=RequestConfig. Custom ()
SetSocketTimeout (timeout * 1000)
SetConnectTimeout (timeout * 1000)
SetConnectionRequestTimeout (timeout * 1000)
The build ();

CodePudding user response:

CloseableHttpClient httpclient=HttpClientBuilder. The create (). SetDefaultRequestConfig (defaultRequestConfig). The build ();
HttpPost HttpPost=new HttpPost (transDto getWebSiteUrl ());

Problem must be out of here, just don't know is what reason,
MultipartEntityBuilder build=MultipartEntityBuilder. The create (). SetMode (HttpMultipartMode. BROWSER_COMPATIBLE);
for(int i=0 ; I & lt; FileList. The size (); I++) {
FileBody FileBody=new FileBody (fileList. Get (I), ContentType. Create (" multipart/form - the data ", "utf-8"));

Last, the conclusion, please? I also encountered this problem
