Spring Boot可执行war文件中的org.atmosphere.cpr.AtmosphereMappingException

我有一个 Spring Boot Application ，我已经整合了 Atmosphere Framework 。

这是Application.java文件：

package com.myproject.something;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;
import org.springframework.core.env.SimpleCommandLinePropertySource;

@SpringBootApplication
public class Application extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Application.class);
    }

    public static void main(String[] args) {
        SpringApplication app = new SpringApplication(Application.class);
        addDefaultProfile(app, new SimpleCommandLinePropertySource(args));
        app.run(args);
    }

    private static void addDefaultProfile(SpringApplication app, SimpleCommandLinePropertySource source) {
        if (!source.containsProperty("spring.profiles.active")
                && !System.getenv().containsKey("SPRING_PROFILES_ACTIVE")) {
            app.setAdditionalProfiles("dev");
        }
    }
}

为了将Atmosphere Framework 集成纳入我的Spring Boot应用程序，我已经松散地关注this resource中official Atmosphere Documentation组合元素。

我最终获得了课程MyAtmosphereConfig.java和MyAtmosphereManagedService.java：

package com.myproject.something.atmosphere;
import java.util.Collections;
import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import org.atmosphere.cpr.AtmosphereServlet;
import org.atmosphere.cpr.ContainerInitializer;
import org.springframework.boot.web.servlet.ServletContextInitializer;
import org.springframework.boot.web.servlet.ServletRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.Ordered;

@Configuration
public class MyAtmosphereConfig {
    @Bean
    public EmbeddedAtmosphereInitializer atmosphereInitializer() {
        return new EmbeddedAtmosphereInitializer();
    }

    @Bean
    public ServletRegistrationBean atmosphereServlet() {
        ServletRegistrationBean registration = new ServletRegistrationBean(new AtmosphereServlet(), "/myAtmosphereUrl");
        registration.addInitParameter("org.atmosphere.cpr.packages", "com.myproject.something.atmosphere");
        registration.setLoadOnStartup(1);
        registration.setOrder(Ordered.HIGHEST_PRECEDENCE);
        return registration;
    }

    private static class EmbeddedAtmosphereInitializer extends ContainerInitializer
            implements ServletContextInitializer {
        @Override
        public void onStartup(ServletContext servletContext) throws ServletException {
            onStartup(Collections.<Class<?>>emptySet(), servletContext);
        }
    }
}

package com.myproject.something.atmosphere;
import java.util.concurrent.ConcurrentHashMap;
import javax.inject.Inject;
import org.atmosphere.config.service.Disconnect;
import org.atmosphere.config.service.ManagedService;
import org.atmosphere.config.service.Ready;
import org.atmosphere.cpr.AtmosphereResource;
import org.atmosphere.cpr.AtmosphereResourceFactory;
import org.json.JSONException;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

@ManagedService(path = "/myAtmosphereUrl")
public class MyAtmosphereManagedService {

    private final Logger log = LoggerFactory.getLogger(MyAtmosphereManagedService.class);

    @Inject
    public static AtmosphereResourceFactory factory;

    @Inject
    public AtmosphereResource resource;

    @Ready
    public void onReady() throws JSONException {
        String atmosJSessionId = resource.getRequest().getRequestedSessionId();
        log.info("Initiating Atmosphere client connection with jsession = " + atmosJSessionId);
    }

    @Disconnect
    public void onDisconnect() {
        String atmosJSessionId = resource.getRequest().getRequestedSessionId();
        log.info("Unregistering Atmosphere client connection with jsession = " + atmosJSessionId);  
    }
}

我一直在 Eclipse IDE 内部开发，将我的Spring Boot Application作为Java应用程序执行。 （右键单击 Application.java - ＆gt;运行方式 - ＆gt; Java应用程序）

按照上述方式运行它 - 从Eclipse IDE中作为 Java Application - 我的应用程序的前端部分可以成功访问公开的URL 通过大气框架如下：

(function() {
  'use strict';
  setTimeout(function() {
    // Setup Atmosphere client
    var myAtmosphereUrl = 'http://localhost:8080/myAtmosphereUrl';
    var socket = atmosphere;
    var subSocket;

    var transport = 'sse';
    var request = {
      url : myAtmosphereUrl,
      contentType : "application/json",
      logLevel : 'debug',
      transport : transport,
      trackMessageLength : true,
      reconnectInterval : 5000
    };
      request.onOpen = function(response) {
      transport = response.transport;
      request.uuid = response.request.uuid;
      console.log("onOpen called!");
    };
      request.onMessage = function(response) {
      transport = response.transport;
      request.uuid = response.request.uuid;
      console.log("onMessage called!");
    };
    subSocket = socket.subscribe(request);
  }, 1000);
})();

在浏览器控制台的前端一侧，我看到HTTP 200状态代码，在 Eclipse IDE控制台的后端一侧，它给了我日志消息Initiating Atmosphere client connection with jsession = A4A8790C27D531FE7B2CD82B5B9C9447。

不幸的是，在打包我的项目进入可执行war文件并在Debian服务器上将其部署为服务之后，它不再起作用了，只留下一条错误消息在后端的日志中：

浏览器控制台为我提供了HTTP 500 - Internal Server Error状态代码。

可执行文件的创建由Maven命令maven package触发，并以pom.xml的方式配置：

我已经尝试将atmosphere.xml文件放入 war文件的WEB-INF文件夹中，但似乎用@ManagedService注释的Servlet仍然是没有拿起。

这是atmosphere.xml的内容，但没有解决错误：

<atmosphere-handlers>
    <atmosphere-handler support-session="true"
                        context-root="/"
                        broadcaster="org.atmosphere.cpr.DefaultBroadcaster"
                        class-name="com.myproject.something.atmosphere.MyAtmosphereManagedService">
    </atmosphere-handler>
</atmosphere-handlers>

有人能告诉我配置有什么问题，或者这可能是与嵌入式Tomcat，Atmosphere和Spring Boot的次要版本相关的一些错误？

编辑：

可以通过克隆official Atmosphere-Spring-Boot Sample project并更改pom.xml以将项目打包到war文件来重现此错误：

我找到了两个修复方法。

首先修复：
1.将pom.xml中的Spring Boot版本更改为：

<parent>
 <groupId>org.springframework.boot</groupId>
 <artifactId>spring-boot-starter-parent</artifactId>
 <version>1.5.7.RELEASE</version>
</parent>

2。完成！

第二次修复：（如果您无法更改版本）

  1. 将项目打包到jar文件中，然后识别@ManagedServices。

    2. 注意：在打包之前，您可能需要在pom.xml中复制静态文件（js和html）。

如果您使用的是 Spring Boot 2，请使用以下经过测试的配置。

@Bean
public ServletRegistrationBean < HttpServlet > PushServlet() {
    ServletRegistrationBean pushServlet = new ServletRegistrationBean(new org.primefaces.push.PushServlet(), "/primepush/*");
    pushServlet.addInitParameter("org.atmosphere.annotation.packages", "org.primefaces.push");
    pushServlet.addInitParameter("org.atmosphere.cpr.packages", "com.ik");
    pushServlet.setAsyncSupported(true);
    pushServlet.setLoadOnStartup(0);
    pushServlet.setOrder(Ordered.HIGHEST_PRECEDENCE);
    return pushServlet;
}

com.ik 是您的项目包名称，即 scan
