java - Atmosphere 无法配置 JSR-356

Question

我创建了 Java Web 应用程序并尝试强制使用 JSR-356，因为据我了解，这是使用原始 javax.servlet.HttpSession 的唯一方法。来自AtmosphereResource目的。

当我将应用程序部署到 Jetty(v. 9.3.7)时，出现以下错误:

如果我使用以下代码强制 native API 优先

params.put(ApplicationConfig.WEBSOCKET_SUPPRESS_JSR356, "true");

然后一切正常。

这是我的部署描述符:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
                             http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
         version="3.0">

    <listener>
        <listener-class>com.sample.guice.GuiceContextListener</listener-class>
    </listener>

    <filter>
        <filter-name>guiceFilter</filter-name>
        <filter-class>com.google.inject.servlet.GuiceFilter</filter-class>
    </filter>

    <filter-mapping>
        <filter-name>guiceFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
</web-app>

用于提供所有绑定(bind)的模块:

public class ServerModule extends AbstractModule
{
    @Override
    protected void configure()
    {
        install(new ServletModule() {
            @Override
            protected void configureServlets()
            {
                Map<String, String> params = new HashMap<>();
                // params.put(ApplicationConfig.WEBSOCKET_SUPPRESS_JSR356, "true");
                serve("/atmosphere").with(AtmosphereGuiceServlet.class, params);
            }
        });
    }
}

我省略了用@ManagedService注释的类和其他一些代码，因为没有问题。正如我所说，使用 native websocket API 一切正常。

Answer 1

消息:在该阶段无法配置 jsr356

意味着，需要在ServletContextInitialization阶段添加jsr356支持，最好在ServletContextListener中添加

我的问题是jetty 9.4原生的websocket不再与 Atmosphere 兼容，另一方面jsr356与guice不兼容

我设法使jsr356与vaadin 8.8.1和jetty 9.4一起工作，但它需要VaadinServlet由Jetty直接管理。这不适用于 Guice，它安装了自己的 GuiceFilter，并且 servlet 不直接注册到 Jetty。

查看 JSR356WebsocketInitializer.initAtmosphereForVaadinServlet 了解更多信息
