我有簡單的聊天Java的網絡套接字,但這是行不通的,我不明白爲什麼。如何用tomcat啓動web-socket應用程序?
服務器類簡單的寫日誌:
@ApplicationScoped
@ServerEndpoint(value = "/index")// May be this mapping but it's don't work.
public class ChatServer {
private static final Logger LOGGER =
Logger.getLogger(ChatServer.class.getName());
@OnOpen
public void onOpen(Session session) {
LOGGER.log(Level.INFO, "New connection with client: {0}",
session.getId());
}
@OnMessage
public String onMessage(String message, Session session) {
LOGGER.log(Level.INFO, "New message from Client [{0}]: {1}",
new Object[] {session.getId(), message});
return "Server received [" + message + "]";
}
@OnClose
public void onClose(Session session) {
LOGGER.log(Level.INFO, "Close connection for client: {0}",
session.getId());
}
@OnError
public void onError(Throwable exception, Session session) {
LOGGER.log(Level.INFO, "Error for client: {0}", session.getId());
}
}
我有一個簡單的客戶端:
<html>
<head>
<title>JEE7 WebSocket Example</title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<script>
var chatClient = new WebSocket("ws://localhost:8080/index");
chatClient.onmessage = function(evt) {
var p = document.createElement("p");
p.setAttribute("class", "server");
p.innerHTML = "Server: " + evt.data;
var container = document.getElementById("container");
container.appendChild(p);
};
function send() {
var input = document.getElementById("message");
var p = document.createElement("p");
p.setAttribute("class", "client");
p.innerHTML = "Me: " + input.value;
var container = document.getElementById("container");
container.appendChild(p);
chatClient.send(input.value);
input.value = "";
}
</script>
</head>
<body>
<h1>JEE7 WebSocket Example</h1>
<div id="container">
</div>
<input type="text" id="message" name="message" />
<button type="button" id="send" onclick="send()">Send</button>
</body>
</html>
但是當我啓動tomcat我有代碼404
。我認爲在我的項目中沒有足夠的東西(類或一些配置文件)。
爲從未使用過的所有類ChatServer
馬克。我認爲這是不正常的。我的項目中缺少什麼成功運行?幫我解決這個問題。謝謝。
,你的意思是對應用程序的名字?這是tomcat運行/調試配置的名稱,或maven項目中的模塊名稱或更多? – Pavel
平均項目名稱,你只是提到頁面名稱,但在localhost:8080有很多項目,所以定義項目,其中包含您的索引頁。 –
我添加/ web-base /由於這個模塊的名稱,它打包在戰爭,但錯誤到js控制檯:chat.html:27 WebSocket連接到'ws:// localhost:8080/web-base/index'失敗:錯誤在WebSocket握手期間:意外的響應代碼:404 – Pavel
