我尝试使用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，我得到以下异常：

关于如何将RESTEasy-CDI合并到我的Maven构建中，我跟着the instructions，我看到WAR正在构建正确。但是，我在部署时仍然会看到异常。
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>

知道可能导致此问题的原因或如何解决此错误？在这一点上，它基本上是一个显示阻止。

发现了这个问题。它只是一个servlet监听器排序问题。我在初始化CDI之前初始化了RESTEasy。
