Jersery 请求过滤器后未调用资源

Question

我定义了两个 SpringServlet，其中一个指向自定义过滤器

@WebServlet(urlPatterns = { "/" }, initParams = {
    @WebInitParam(name = "com.sun.jersey.config.property.packages", value = "com.x.y.resource"),
    @WebInitParam(name = "com.sun.jersey.api.json.POJOMappingFeature", value = "true") })
public class JerseyServlet extends SpringServlet
{
}

@WebServlet(name = "secure", urlPatterns = "/secure/*", initParams = {
    @WebInitParam(name = "com.sun.jersey.config.property.packages", value = "com.x.y.resource"),
    @WebInitParam(name = "com.sun.jersey.spi.container.ContainerRequestFilters", value = "com.x.y.resource.OAuthFilter"),
    @WebInitParam(name = "com.sun.jersey.api.json.POJOMappingFeature", value = "true") })
public class JerseySecureServlet extends SpringServlet
{
}

想法是任何包含“/secure/”的 URLs 都被定向到 OAuthFilter 以验证 OAuth headers 的请求。所有其他 URL 都正常处理。

对于发送到不包含“/secure/”的 URL 的任何请求，正确调用适当的 JAX-RS 资源 class。然而，对于包含“/secure/”的 URLs，OAuthFilter 被正确调用，但是 JAX-RS 注释资源 class 之后永远不会被调用。

这是一个安全资源示例

@Component
@Scope("request")
@Path("/secure/example")
public class SecureResource
{
    @GET
    ...
}

这是 OAuthFilter

@Provider
@Component
public class OAuthFilter implements ContainerRequestFilter
{
    public static final String AUTHORIZED_USER = "authorized_user";

    @Autowired
    AccessTokenService accessTokenService;

    @Autowired
    UserService userService;

    @Context
    HttpServletRequest httpRequest;

    @Override
    public ContainerRequest filter(ContainerRequest containerRequest)
    {
        OAuthServerRequest request = new OAuthServerRequest(containerRequest);
        OAuthParameters params = new OAuthParameters();
        params.readRequest(request);

        String accessToken = params.getToken();

        if (accessToken == null)
        {
            throw new WebApplicationException(Status.UNAUTHORIZED);
        }

        String userId = accessTokenService.getUserIdForToken(accessToken);

        if (userId == null)
        {
            throw new WebApplicationException(Status.UNAUTHORIZED);
        }

        User user = userService.get(userId);

        if (user == null)
        {
            throw new WebApplicationException(Status.NOT_FOUND);
        }

        httpRequest.setAttribute(AUTHORIZED_USER, user);

        return containerRequest;
    }
}

看起来一旦选择了带有“/secure/*”映射的 JerseySecureServlet 并调用了 OAuthFilter，baseURI 是 "http:/ip:port/context/secure" 并且路径只是“/example”，没有资源对应这条路径，所以什么都不会被调用。我应该怎么做才能仅将此过滤器应用于包含“/secure/”的 URL？

我已经解决了这个问题，但我不能 100% 确定我的解决方案是否是正确的方法。我已经将过滤后的 serlvet 上的注释更改为 @WebFilter，给我

@WebServlet(urlPatterns = { "/*" }, initParams = {
    @WebInitParam(name = "com.sun.jersey.config.property.packages", value = "com.x.y.resource"),
    @WebInitParam(name = "com.sun.jersey.api.json.POJOMappingFeature", value = "true") })
public class JerseyServlet extends SpringServlet
{
}

@WebFilter(urlPatterns = "/secure/*", initParams = {
    @WebInitParam(name = "com.sun.jersey.config.property.packages", value = "com.x.y.resource"),
    @WebInitParam(name = "com.sun.jersey.spi.container.ContainerRequestFilters", value = "com.x.y.resource.OAuthFilter"),
    @WebInitParam(name = "com.sun.jersey.api.json.POJOMappingFeature", value = "true") })
public class JerseySecureFilter extends SpringServlet
{
}

这行得通。比这个更好的解决方案将被接受。
