Websocket JSR-356在Jetty 9.4.1中失败 [英] Websocket JSR-356 fail with Jetty 9.4.1
本文介绍了Websocket JSR-356在Jetty 9.4.1中失败的处理方法，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
我当前的Web服务器是嵌入式Jetty 9.1.5。它与JSR-356一起很好地创建websocket。这些天，我正在尝试升级到Jetty 9.4.1。除了websocket之外，其他所有东西都运行良好。
我的代码如下：
My current web server is embedded Jetty 9.1.5. It works well with JSR-356 to create websocket. These days, I am trying to upgrade to Jetty 9.4.1. Everything works nicely except websocket.
My code like below:
- 嵌入式码头和Websocket库：
<dependency>
<groupId>org.eclipse.jetty</groupId>
<artifactId>jetty-server</artifactId>
<version>9.4.1.v20170120</version>
</dependency>
<dependency>
<groupId>org.eclipse.jetty</groupId>
<artifactId>jetty-webapp</artifactId>
<version>9.4.1.v20170120</version>
</dependency>
<dependency>
<groupId>org.eclipse.jetty</groupId>
<artifactId>jetty-annotations</artifactId>
<version>9.4.1.v20170120</version>
</dependency>
<dependency>
<groupId>org.eclipse.jetty.websocket</groupId>
<artifactId>javax-websocket-server-impl</artifactId>
<version>9.4.1.v20170120</version>
</dependency>
- 服务器端点：
@ServerEndpoint(value = "/ws/communication/{officeId}/{username}/{oldWSSession}")
class WSCommunication {
// @OnOpen, @OnMessage, @OnClose methods
}
-
Jetty服务器，Webapp上下文， Websocket配置：
Jetty server, Webapp context, Websocket configuration:
// Jetty server
Server server = new Server();
String[] configFiles = {"./etc/jetty.xml"};
for (String configFile : configFiles) {
XmlConfiguration configuration = new XmlConfiguration(new File(configFile).toURI().toURL());
configuration.configure(server);
Connector[] connectors = server.getConnectors();
if (connectors != null && connectors.length == 2) {
ServerConnector serverConnector = (ServerConnector) connectors[1];
serverConnector.setPort(8443);
}
}
// Webapp context
WebAppContext webContext = new WebAppContext(ResourceManager.getWebappsPath(), "/myContext");
webContext.setContextPath("/myContext");
webContext.setResourceBase(ResourceManager.getWebappsPath() + contextPath);
webContext.setInitParameter("org.eclipse.jetty.servlet.Default.dirAllowed", "false");
private List<WebAppContext> listWebContext = new ArrayList<>();
listWebContext.add(webContext);
ContextHandlerCollection contexts = new ContextHandlerCollection();
contexts.setHandlers(listWebContext.toArray(new WebAppContext[listWebContext.size()]));
server.setHandler(contexts);
// Start server
server.start();
// Websocket
ServerContainer container =
WebSocketServerContainerInitializer.configureContext(webContext);
container.addEndpoint(webContext.getClassLoader().loadClass(
"com.example.WSCommunication"));
container.setDefaultMaxSessionIdleTimeout(84600);
// Dump server log
server.dumpStdErr();

上面的代码在Jetty 9.1.5.v20140505和Java 7上运行良好，但是当我失败时升级到Jetty 9.4.1.v20170120和Java8。
浏览器控制台报告404错误。
The above code works fine with Jetty 9.1.5.v20140505 and Java 7 but when fail when I upgrade to Jetty 9.4.1.v20170120 and Java 8. Browser console report an 404 error.
WebSocket connection to 'wss://localhost:8443/myContext/ws/communication/5/kbui/None' failed: Unexpected response code: 404
升级Jetty时是否错过了某些东西？
预先感谢。
Did I miss something when upgrade Jetty?
Thanks in advance.
推荐答案
从您的设置来看，您将得到...
Judging from your setup, you'll wind up with ...
wss：// localhost：8443 / myContext / ws / communication / 5 / kbui /无
您的 contextPath 不是 / context ，实际上是您设置中的 / myContext 。
Your contextPath isn't /context, its actually /myContext in your setup.
转储上的Servlet映射部分（t帽子是重要的部分。 heh）
You trimmed out the Servlet Mappings section on the dump (that was the important part. heh)
但是尝试手动添加 WebAppContext WSCommunication 端点从 WebAppClassloader 或WebApp的ServletContext外部访问c $ c>也可能是一个问题。
But attempting to manually add the WSCommunication Endpoint contained in WebAppContext from outside of the WebAppClassloader or the WebApp's ServletContext is probably going to be a problem as well.
您有3种选择：
-
JSR356自动方式
为您的 WebAppContext 设置字节码扫描和注释发现，并让启动程序发现并自动加载 WSCommunication 端点。
Setup bytecode scanning and annotation discovery for your WebAppContext and let the startup discover and auto-load the WSCommunication endpoint.
将以下内容添加到您的 webContext ...
Add the following to your webContext ...
webContext.setAttribute("org.eclipse.jetty.websocket.jsr356",Boolean.TRUE);
webContext.setConfigurations(new Configuration[] {
new AnnotationConfiguration(),
new WebXmlConfiguration(),
new WebInfConfiguration(),
new PlusConfiguration(),
new MetaInfConfiguration(),
new FragmentConfiguration(),
new EnvConfiguration()});
并将 jetty-annotations 依赖项添加到您的项目。
And add the jetty-annotations dependency to your project.
-
JSR356手动方式
使用 javax.websocket.server.ServerApplicationConfig 报告 WSCommunication
Servlet规范手册方法
这是最简单的方法。
创建一个 javax.servlet.ServletContextListener ，将 WSCommunication 端点添加到 ServerContainer
This is the easiest approach.
Create a javax.servlet.ServletContextListener that adds the WSCommunication endpoint to the ServerContainer
public class MyContextListener implements ServletContextListener
{
@Override
public void contextDestroyed(ServletContextEvent sce)
{
}
@Override
public void contextInitialized(ServletContextEvent sce)
{
ServerContainer container = (ServerContainer)sce.getServletContext()
.getAttribute(ServerContainer.class.getName());
try
{
container.addEndpoint(WSCommunication.class);
}
catch (DeploymentException e)
{
throw new RuntimeException("Unable to add endpoint",e);
}
}
}
