java - Tomcat 7 上的 RESTEasy CDI 部署异常

Question

我正在尝试使用 RESTEasy 3.0.6 在 Tomcat 7.0 上部署 Web 应用程序以获得 RESTful 服务支持。但是，当我尝试部署应用程序时，出现以下异常:

我关注了the instructions关于如何将 RESTEasy-CDI 合并到我的 Maven 构建中，我看到 WAR 正在正确构建。但是，我在部署时仍然看到异常。

我的 web.xml 文件的相关部分如下所示:

  <listener>
    <listener-class>
            org.jboss.resteasy.plugins.server.servlet.ResteasyBootstrap
        </listener-class>
  </listener>
  <listener>
    <listener-class>org.jboss.weld.environment.servlet.Listener</listener-class>
  </listener>
    <filter>
        <filter-name>ConversationPropagationFilter</filter-name>
        <filter-class>org.jboss.weld.servlet.ConversationPropagationFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>ConversationPropagationFilter</filter-name>
        <url-pattern>*</url-pattern>
    </filter-mapping>

  </servlet-mapping>
  <context-param>

    <param-value>/rest</param-value>
  </context-param>

知道可能导致此错误的原因或如何解决此错误吗？在这一点上，它基本上是一个表演终结者。

发现问题。这只是一个 servlet 监听器排序问题。我在初始化 CDI 之前初始化 RESTEasy。
