REST async Operation wirft ProcessingException

Ich baue eine REST API mit Jax-rs 2. Ich erhalte immer eine Ausnahme, wenn ich versuche, den REST-Dienst auszuführen. Ich renne, um nach asyncResponse zu suchen. Ich bin mir nicht sicher, was ich mit der asyncResponse falsch mache. Wie ohne es, der Code läuft gut.REST async Operation wirft ProcessingException

Auch der Web-Container ist Tomcat 7.

hier wird der Stack-Trace Ausnahme:

WARNING: Attempt to put servlet request into asynchronous mode has failed. Please check your servlet configuration - all Servlet instances and Servlet filters involved in the request processing must explicitly declare support for asynchronous request processing. 
java.lang.IllegalStateException: A filter or servlet of the current chain does not support asynchronous operations.

arbeitete für mich, danke! – svarog

Ich habe Version 2.5 verwendet und als ich die Version geändert habe, funktioniert es, danke – ganchito55

Tomcat Abhängigkeit

http://tomcat.apache.org/whichversion.html

Also stellen Sie zuerst sicher, dass Sie mindestens Tomcat 7 verwenden Wenn Sie Ihren Kater mit mvn starten sollten Sie

mvn tomcat7:run

Stellen Sie sicher,

INFO: Starting Servlet Engine: Apache Tomcat/7.0.47

Tomcat Protokoll

das NIO-Protokoll für Ihren Anschluss

eingestellt siehe die folgende Zeile verwenden

Wenn Sie mvn verwenden

<plugin> 
    <groupId>org.apache.tomcat.maven</groupId> 
    <artifactId>tomcat7-maven-plugin</artifactId> 
    <configuration> 
    <protocol>org.apache.coyote.http11.Http11NioProtocol</protocol> 
    </configuration> 
</plugin>

sonst in Ihrem server.xml

<Connector port="8080" 
protocol="org.apache.coyote.http11.Http11NioProtocol" 
... 
/>

Sie so etwas in Ihrer tomcat logs

INFO: Starting ProtocolHandler ["http-nio-8080"]

Jar Abhängigkeiten

Überprüfen Sie haben keine Abhängigkeit von Servlet sehen sollte 2.5

mit mvn

mvn dependency:tree

Beachten Sie, dass Sie auch jsp-api v2.2

Web verwenden sollten.xml

Ändern Sie Ihre web.xml verwenden Version 3.0, https://docs.oracle.com/cd/E24329_01/web.1211/e21049/web_xml.htm#WBAPP503

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

Fügen Sie den

<async-supported>true</async-supported>

innen alle <servlet></servlet> und <filter></filter> (keine Notwendigkeit, innerhalb init-param sein)
