Jboss RESTEasy-在接口中标记@Path时资源类注册失败

我正在JBoss4.3.0.GA上使用RESTEasy 2.0.1.GA。 我的资源类实现的接口如下所示：

@Path("/")
public interface CwindRestfulService {
@GET
@Path("accounts/{email}")
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_FORM_URLENCODED)
public Account getAccountInfo(@PathParam("email") String email) throws Exception;
}

当我在web.xml中设置resteasy.scan=true时，效果很好。但在spring上下文中应该是错误的。现在我的web.xml是：

<web-app>
    <display-name>Archetype RestEasy Web Application</display-name>
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>WEB-INF/applicationContext.xml</param-value>
    </context-param>    
    <context-param>
        <param-name>resteasy.resources</param-name>
        <param-value>com.cwind.rest.CwindRestfulServiceImpl</param-value>
    </context-param>
    <listener>
        <listener-class>org.jboss.resteasy.plugins.server.servlet.ResteasyBootstrap</listener-class>
    </listener>
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <servlet>
        <servlet-name>Resteasy</servlet-name>
        <servlet-class>org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>Resteasy</servlet-name>
        <url-pattern>/*</url-pattern>
    </servlet-mapping>
</web-app>

这表明我错过了@Path，而实际上我没有。但当我将注释放入资源类时，它确实起作用。我在谷歌上搜索并找到了一个解决方案。它需要添加@ApplicationPath注释。现在我的接口在第三方库中，所以我不能修改它。有人有什么建议吗？提前感谢。

您似乎尚未注册特定于Resteasy的

SpringContextLoaderListener

。这是Spring向Resteasy注册扫描的资源类所必需的

下面是web.xml配置示例（它使用注释配置，但也可用于xml配置）：

非常感谢格雷格！现在它起作用了。但还有一件事，@Path必须添加到资源类中，当注释仅在接口中时，它将不起作用。
