将ContainerResponseFilter添加到jetty服务器

Question

我想将ContainerResponseFilter和ContainerRequestFilter添加到我的jetty-server。但是当我尝试添加它时，我得到的错误是该类不好。

我的码头服务器设置：

ServletContextHandler context = new ServletContextHandler(ServletContextHandler.SESSIONS);
context.setContextPath("/");
context.addFilter(CorsFilter.class, //Error here
    "/*", EnumSet.of(DispatcherType.REQUEST));

Server jettyServer = new Server(8090);
jettyServer.setHandler(context);

ServletHolder jerseyServlet =
    context.addServlet(ServletContainer.class, "/*");
jerseyServlet.setInitOrder(0); 
jerseyServlet.setInitParameter("jersey.config.server.provider.classnames",
    Login.class.getCanonicalName());

Starter.start(jettyServer);

和我的过滤器：

public class CorsFilter implements ContainerRequestFilter, ContainerResponseFilter  {

错误是该方法未解决。谢谢！

ContainerRequestFilter和ContainerResponseFilter不是Servlet过滤器，它们是JAX-RS过滤器。

将它们注册到ResourceConfig实现中。

例：

@ApplicationPath("/")
public class MyApplication extends ResourceConfig {

    public MyApplication() {
        // Register resources and providers using package-scanning.
        packages("my.package");

        // Register my custom provider - not needed if it's in my.package.
        register(CorsFilter.class);
        // Register an instance of LoggingFilter.
        register(new LoggingFilter(LOGGER, true));

        ...
    }
}
