Ii. Cause Analysis

I found the following reason in Baidu:
Clientabortexception:Java.net. socketexception: Connection reset by peer: Socket write error is caused by a "clientabortexception ", it is an exception in I/O processing and should be captured by the application server.
Connection reset by peerCause:
Frequent Connection reset by peer: there may be many reasons, but the more common reasons are:
①: When the number of concurrent connections on the server exceeds its capacity, the server will shut down some of the connections;
②: The client closes the browser, and the server is still sending data to the client;
③: The browser presses stop.
Many people say that it is caused by the client and there is no way to control it. This is a depressing problem.
 

However, a buddy said well, ifClientabortexception:Yes. Do not output these exceptions.

Specific methods

Code:

1. Try {
3. // Put the processing code in try ...... In the Catch Block, use the judgment function in the catch part to prevent the system from throwing clientabortexception,
5. Chartutilities. writechartasjpeg (response. getoutputstream (), chart, 600,400 );
7. } Catch (exception e ){
8. String simplename = E. getclass (). getsimplename ();
9. If ("clientabortexception". Equals (simplename )){
10. System. Out. println ("refreshing the client too fast ");
11. } Else
12. E. printstacktrace ();
14. }
15. Return Mapping. findforward ("succ ");
16. }

 

Iii. Conclusion

This is acceptable.
