在Tomcat8服务器上部署时，WebSocket应用程序无法正常运行
[英]WebSocket application doesn't work properly when deployed on Tomcat8 server
问题描述
问题
我正在尝试以最小的源代码更改运行此示例： https : //spring.io/guides/gs/messaging-stomp-websocket/
我已经设法使用Eclipse和Maven以及终端窗口再次使用maven来运行它。 我还设法将其打包成.war文件，并使用java -jar myfile.war在终端中运行。在这种情况下，它可以按预期工作，即localhost：8080显示简单的界面，并在其中连接并返回问候语同一窗口。 当将.war文件部署到在RaspberryPi上运行的tomcat8服务器时，就会出现问题。 在这种情况下，将显示index.html，但是“连接”按钮什么也不做，这使我相信这是与javascript相关的问题。 服务器工作正常，顺便说一句，我在上面部署了其他东西。
我尝试过的事情
- 编辑了.war存档，使index.html和.js文件不在WEB-INF目录中，以便外界可以访问它们。 问题仍然存在。
- 将对index.html中的.js文件的脚本引用更改为
<script src="http://cdn.sockjs.org/sockjs-0.3.4.js"></script> <script src="http://cdnjs.cloudflare.com/ajax/libs/stomp.js/2.3.3/stomp.js"></script>
因此，如果.war文件有任何问题，它们可以通过CDN交付。 问题仍然存在。
- 为Servlet添加了额外的功能，以使其在其他目录中显示一些数据，只是为了确保它可以工作，而.war文件不是问题。 看起来不错，但是上述问题显然仍然存在。
码
入口点
@SpringBootApplication
public class Application extends SpringBootServletInitializer {
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Application.class);
}
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
问候语将被返回。
public class Greeting {
private String content;
public Greeting(String content) {
this.content = content;
}
public String getContent() {
return content;
}
}
控制者
@Controller
public class GreetingController {
@MessageMapping("/hello")
@SendTo("/topic/greetings")
public Greeting greeting(HelloMessage message) throws Exception {
Thread.sleep(3000); // simulated delay
return new Greeting("Hello, " + message.getName() + "!");
}
}
要发送的消息
public class HelloMessage {
private String name;
public String getName() {
return name;
}
}
WebSocket配置
@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer {
@Override
public void configureMessageBroker(MessageBrokerRegistry config) {
config.enableSimpleBroker("/topic");
config.setApplicationDestinationPrefixes("/app");
}
public void registerStompEndpoints(StompEndpointRegistry registry) {
registry.addEndpoint("/hello").withSockJS();
}
}

最后的想法
同样，通过消除过程，.js库未正确导入，或者服务器的WebSocket支持出现问题。 我真的很坚持这一点，我们将不胜感激。

因此，基本上可能会发生的事情是，一旦部署到服务中，您的所有路径都会有些偏离，所以可以说您有一个链接，它表示<a href="/home" > home </a>可以在本地运行，但可以在服务器上不起作用，因为您的应用程序URL现在是host：8080 / appName /，并且当您使用/ home引用任何内容而不是将您带到host：8080 / appName / home时，它将带您到host：8080 / home将其指向损坏的网址。 因此，我认为您可以通过在此处更改/ hello来解决问题
function connect() {
var socket = new SockJS('hello');
stompClient = Stomp.over(socket);
stompClient.connect({}, function(frame) {
setConnected(true);
console.log('Connected: ' + frame);
stompClient.subscribe('/topic/greetings', function(greeting){
showGreeting(JSON.parse(greeting.body).content);
});
});
}

我尝试了春季指南示例，它与Google chrome版本54.0.2840.100（64位）完美配合
