将Apache Jersey for REST Web服务与struts2 Web应用程序集成

我有一个使用struts2框架的Web应用程序。我想使用Apache Jersey向其添加REST Web服务支持。我已经按应用程序进行了配置，但是在尝试运行Web服务时却出现404错误。我在互联网上进行搜索，发现过滤器拦截了所有请求，从而使servlet映射无用。我还通过配置struts.xml排除了URL模式，从而找到了解决方案，但仍然存在未找到404的相同问题。我在下面附上我的代码。提前致谢。

import javax.ws.rs.core.MediaType;


@Path("/hello")
public class Hello {
    @GET
