J'ai une application Boot Spring dans lequel j'ai intégré le Atmosphere Framework.org.atmosphere.cpr.AtmosphereMappingException dans le fichier exécutable de guerre Spring Boot
Ce fichier est le Application.java:
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");
}
}
}
Afin d'avoir l'atmosphère Cadre intégré dans mon application Boot Spring, j'ai vaguement suivions this resource combinant des éléments du official Atmosphere Documentation.
J'ai fini les classes MyAtmosphereConfig.java et 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);
}
}
je développe dans le Eclipse IDE, exécuter mon application Boot Spring comme Java Application. (Clic droit sur Application.java -> Exécuter en tant que -> Application Java)
Courir comme décrit de la façon ci-dessus -comme application Java à partir de l'Eclipse Front-IDE-End une partie de mon application peut accéder avec succès l'URL exposée par le cadre de l'atmosphère comme ceci:
(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);
})();
sur le Frontend côté dans la console du navigateur Je vois HTTP 200 le statut de co de et sur le côté Backend dans la console IDE Eclipse , il me donne le message de journal Initiating Atmosphere client connection with jsession = A4A8790C27D531FE7B2CD82B5B9C9447.
Malheureusement, après emballage mon projet dans un fichier de guerre exécutable et le déployer en tant que service sur un serveur Debian, il ne me laissant fonctionne plus avec un message d'erreur dans le journal sur le côté back-end:

La console du navigateur me donne un code d'état HTTP 500 - Internal Server Error.

J'ai déjà essayé de placer un fichier atmosphere.xml dans le dossier WEB-INF de le fichier de guerre , mais il semble toujours que la servlet annotée avec @ManagedService ne soit pas ramassée.
C'était le contenu du atmosphere.xml, qui ne résout pas l'erreur:
<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>
Quelqu'un peut-il me dire ce qui est erroné avec ma configuration ou est ce qui a probablement un bug lié aux versions mineures du embarqué Tomcat, atmosphère et botte de printemps?
EDIT:
Il est possible de reproduire cette erreur par clonage du official Atmosphere-Spring-Boot Sample project et en changeant le pom.xml pour emballer le projet dans un fichier war:
