Question

我正在使用Atmosphere做一个websocket应用程序，我正在尝试在我自己的环境中重现chat sample。我正在使用TomEE 7 plus服务器，示例工作正常。

我将maven依赖添加到了大气运行时和servlet 3.0，就像它在示例中所做的那样

    <!-- PubSub dependencies -->
    <dependency>
        <groupId>org.atmosphere</groupId>
        <artifactId>atmosphere-runtime</artifactId>
        <version>2.3.3</version>
    </dependency>

    <!-- Spécification servlet 3.0 nécessaire pour atmosphere -->
    <dependency>
        <groupId>org.apache.geronimo.specs</groupId>
        <artifactId>geronimo-servlet_3.0_spec</artifactId>
        <version>1.0</version>
    </dependency>

然后我将我的servlet放在web.xml文件中

<!-- Atmosphere Servlet -->
<servlet>
    <description>AtmosphereServlet</description>
    <servlet-name>AtmosphereServlet</servlet-name>
    <servlet-class>org.atmosphere.cpr.AtmosphereServlet</servlet-class>
    <!-- limit classpath scanning to speed up starting, not mandatory -->
    <init-param>
        <param-name>org.atmosphere.cpr.packages</param-name>
        <param-value>my.package.web.websocket</param-value>
    </init-param>
    <init-param>
        <param-name>org.atmosphere.interceptor.HeartbeatInterceptor.clientHeartbeatFrequencyInSeconds</param-name>
        <param-value>10</param-value>
    </init-param>
    <load-on-startup>0</load-on-startup>
    <async-supported>true</async-supported>
</servlet>
<servlet-mapping>
    <servlet-name>AtmosphereServlet</servlet-name>
    <url-pattern>/chat/*</url-pattern>
</servlet-mapping>

但是当我尝试在AtmosphereResource课程中注入Chat时，我收到了这个错误：

哈和另一个有用的信息我不使用ObjectMapperInjectable.java所以我没有META-INF/Services/org.atmosphere.inject.Injectable文件（它在样本中使用）。我的项目中有一个beans.xml，我可以在Chat.java

注入我的业务服务

我知道它没有找到Default限定符，但我不明白为什么。

我是否需要为AtmospherResource界面指定限定符（我不这么认为）？是不是有默认实现？

有人解决了同样的问题吗？

由于

修改

经过一些测试后，似乎来自beans.xml。如果我在META-INF /下的原始示例项目中添加它，我得到了同样的错误。

找不到限定符的Api类型[org.atmosphere.cpr.AtmosphereResource]
