无法运行spring web socket演示 [英] Not able to run spring web socket demo
本文介绍了无法运行spring web socket演示的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在尝试运行spring web socket的演示，但无法完全测试它。我使用的是java 7和tomcat 7.0.50。我在服务器启动时没有收到任何错误，但是当我用js打开网页连接到它时，我找不到404页面。我不确定我是否缺少配置中的任何内容以使其运行以及如何从js端连接它。
我有以下xml文件：
< beans ....>
< context：annotation-config />
< websocket：message-broker
application-destination-prefix =/ app>
< websocket：stomp-endpoint path =/ hello>
< websocket：sockjs />
< / websocket：stomp-endpoint>
< websocket：simple-broker prefix =/ topic/>
< / websocket：message-broker>
< / beans>
我的控制器类是：
@Controller
公共类SwsService {
@MessageMapping（/ hello）
@SendTo（/ topic / greetings）
公共问候语greeting（HelloMessage消息）抛出异常{
返回新的Greeting（Hello，+ message.getName（）+！）;
}
public String getGreeting（）{
return你好，你在！;
}
}
我称之为的js是：
var sock = new SockJS（/ hello）;
sock.onopen = function（）{
console.log（open）;
};
sock.onclose = function（）{
console.log（closed）;
};
sock.onmessage = function（message）{
console.log（msg，message）;
};
运行tomcat时的控制台输出：

但它也无济于事。当我运行 mvn tomcat7：run 时，我看到以下输出和浏览器上的打开url告诉404。

卡住了那里并没有继续。
解决方案
我遇到了同样的问题。这个帖子给了我足够的线索来解决这个问题。非常感谢。
解决方案：
如果您在web.xml中配置了Spring MVC Dispatcher Servlet并映射到如下所示的网址格式
< servlet-mapping>
< servlet-name> dispatcher< / servlet-name>
< url-pattern> / webui / *< / url-pattern>
< / servlet-mapping>
然后你必须创建SockJS实例，如下所示
var socket = new SockJS（'/ contextPath / webui / hello'）;
注意：替换 contextPath 与您的应用程序上下文路径。
I am trying to run a demo of spring web socket but not able to test it completely. I am using java 7 and tomcat 7.0.50. I don't get any error while server startup, but when I open the web page with js making the connection to it I got 404 page not found. I am not sure if I am missing anything in configuration to make it run and how can I be able to connect it from js side.
I have following xml file:
<beans ....>
<context:annotation-config />
<websocket:message-broker
application-destination-prefix="/app">
<websocket:stomp-endpoint path="/hello">
<websocket:sockjs />
</websocket:stomp-endpoint>
<websocket:simple-broker prefix="/topic" />
</websocket:message-broker>
</beans>
My controller class is:
@Controller
public class SwsService {
@MessageMapping("/hello")
@SendTo("/topic/greetings")
public Greeting greeting(HelloMessage message) throws Exception {
return new Greeting("Hello, " + message.getName() + "!");
}
public String getGreeting() {
return "Hello, you are in!";
}
}
The js from which I am calling this is:
var sock = new SockJS("/hello");
sock.onopen = function () {
console.log("open");
};
sock.onclose = function () {
console.log("closed");
};
sock.onmessage = function (message) {
console.log("msg", message);
};
The console output when I run the tomcat:

How can I successfully test it?
Updates
I also tried running the portfolio example from here: https://github.com/rstoyanchev/spring-websocket-portfolio as suggested by @jhadesdev
But it also doesn't help. When I run mvn tomcat7:run, I see following output and open url on browser tells 404.

It stuck there and doesn't go ahead.
解决方案
I was facing the same problem. This thread gave me enough clues to solve the problem. Thanks a lot.
SOLUTION: In case you have a Spring MVC Dispatcher Servlet configured in your web.xml and mapped to a url-pattern as shown below
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>/webui/*</url-pattern>
</servlet-mapping>
Then you have to create the SockJS instance as shown below
var socket = new SockJS('/contextPath/webui/hello');
NOTE: Replace contextPath with your application context path.
