单例的UserBox类
public class UserBox{
//单例代码省略
private Map<String, Queue<String>> box;
public Boolean AddUserBox(String userId){
try{
synchronized(this){
if(box.containsKey(userId)){ return false;}
else{
Queue<String> userBox = new LinkedBlockingQueue<String>();
box.put(userId, userBox);
return true;
}
}
}
catch(Exception e){return false;}
}
public String GetUserInfo(String userId){
if(!box.containsKey(userId)) return "";
else{
try{
while(box.get(userId).size()==0){
Thread.sleep((long)1000.0);
}
String message = box.get(userId).poll();
return message;
}
catch(Exception e){return "";}
}
}
public Boolean PutInfoToBox(String userId, String infoJson){
try{
synchronized(this){
if(!box.containsKey(userId)) return false;
else{
Queue<String> userBox = box.get(userId);
userBox.offer(infoJson);
return true;
}
}
}
catch(Exception e){return false;}
}
}
客户端用C#语言调用了通过httpwebRequest调用controller中的接口：
while(true){
string url="";
HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create("http://localhost:8080/infopublish/getsubscribeinfo.do?userInfo="+args[0]);
myRequest.Method = "GET";
myRequest.ContentType = "text/plain:charset-UTF-8";
//myRequest.Timeout = 5000;
//Stream newStream = myRequest.GetRequestStream();//这里提示无法连接到远程服务器
//newStream.Close();
HttpWebResponse res = (HttpWebResponse)myRequest.GetResponse();
stream responseStream = res.GetResponseStream();
StreamReader sr = new StreamReader(responseStream, Encoding.GetEncoding("utf-8"));
string backstr = sr.ReadToEnd();
sr.Close();
responseStream.close();
res.Close();
console.writeline(backstr);
}
我开启了120个这样的客户端，2个发布消息的客户端，每隔1秒调用publishInfo接口随机向120个用户发布消息，一开始120个客户端都能及时的收到，但是隔一会客户端会报超时异常，这个是正常的，之后偶尔还能收到信息，但是再过一会每个客户端就出现无法连接远程服务器，error 10061目标主机主动拒绝，连接不能建立。
关掉所有客户端，重启1个新的客户端仍然是这样，但是服务端没有报任何错误。
还请大侠帮忙分析下，是不是服务端连接太多有限制啊，还是服务端出现了太多了超时链接后干脆拒绝了所有请求？
