我的应用程序需要通过http://127.0.0.1/...(localhost url)联系它正在处理的同一设备.
出于某种原因,当我到达那里有JSON内容的网站时,大约50%的时间(可能正好是50%),我得到例外:
java.net.SocketException:recvfrom失败:ECONNRESET(由对等方重置连接)
对于其他50%,我得到了非常好的结果.我试图进行民意调查(甚至民意调查之间的延迟很大),但我仍然得到同样奇怪的结果.
我搜索过互联网,也在这里,我不确定为什么会这样.对等方是否意味着客户端已经造成了这种情况？为什么会这样,我该如何处理？
一些网站说这是常见的事情,但我没有找到在这种情况下最好的事情.

我的servlet程序是
response.setContentType("application/octet-stream");
response.setHeader("Content-Disposition","attachment;filename="+filename);
FileInputStream in = new FileInputStream(new File(filepath));
ServletOutputStream output=response.getOutputStream();
byte[] outputByte=new byte[4096];
while(in.read(outputByte,0,4096)!=-1){
output.write(outputByte,0,4096);//error indicates in this line
}
in.close();
output.flush();
output.close();
如何解决这个问题？
我打电话给https webservice,之前它的工作正常,但现在当我试图调用它时,它会给我以下错误.

我想知道这意味着什么,有没有办法解决它？目前,它会导致数据检索延迟.此外,它泛滥日志,我不能真的忽略它..我想知道我是否可以改善这种情况.
当我处理REST服务时,这是我应该期待的吗？我的服务器在Amazon EC2上.
