java - 使独立的 grizzly2 JAX-RS 接受 URL 中的编码 URL？

Question

我正在尝试将一个可能存在泄漏的库封装在其自己的独立 JVM 中，并使用 REST 调用它。我有一个 Java EE 7 Web 应用程序可以执行此操作，但我想要一个独立版本。为此，我使用创建了一个小型 Maven 项目

mvn archetype:generate -DarchetypeGroupId=org.glassfish.jersey.archetypes \
 -DarchetypeArtifactId=jersey-quickstart-grizzly2 -DarchetypeVersion=2.27

这给了我一个带有这个 Main 的小项目。

public class Main {
    // Base URI the Grizzly HTTP server will listen on
    public static final String BASE_URI = "http://localhost:8080/verapdf/";

    /**
     * Starts Grizzly HTTP server exposing JAX-RS resources defined in this application.
     * @return Grizzly HTTP server.
     */
    public static HttpServer startServer() {
        // create a resource config that scans for JAX-RS resources and providers
        // in dk.kb.dpa.verapdf package
        final ResourceConfig rc = new ResourceConfig().packages("dk.kb.dpa.verapdf");

        // create and start a new instance of grizzly http server
        // exposing the Jersey application at BASE_URI
        return GrizzlyHttpServerFactory.createHttpServer(URI.create(BASE_URI), rc);
    }

    /**
     * Main method.
     * @param args
     * @throws IOException
     */
    public static void main(String[] args) throws IOException {
        final HttpServer server = startServer();
        System.out.println(String.format("Jersey app started with WADL available at "
                + "%sapplication.wadl\nHit enter to stop it...", BASE_URI));
        System.in.read();
        server.stop();
    }
}

我添加了自己的小资源，如下所示:

.
.
.
@Path("validate")
public class JAXRSValidator {

    @GET
    @Path("{url}")
    @Produces(MediaType.APPLICATION_XML)
    public String validate(@PathParam("url") String url) throws Exception 
.
.
.

到目前为止，我可以调用 http://localhost:8080/verapdf/validate/123 并在方法内命中断点，并将 url 设置为123。然而，我想在这里有一个真实的 URL(它是绝对的，并且包含斜杠和井号)，这会给出错误 500。由于未调用该方法，我怀疑 Web 容器和/或 JAX-RS 不喜欢我的编码 URL 位于正确的位置，就像 Tomcat 所做的那样。

如何解决这个问题？另一种方法也不错，只要我最终得到一个提供 REST 服务的独立二进制文件。

正如评论中提到的，斜杠解码存在问题。您可以显式启用解码斜杠:

public static HttpServer startServer() {
    final ResourceConfig rc = new ResourceConfig().packages("dk.kb.dpa.verapdf");
    HttpServer httpServer = GrizzlyHttpServerFactory.createHttpServer(URI.create(BASE_URI), rc);
    httpServer.getHttpHandler().setAllowEncodedSlash(true);
    return httpServer;
}

没有 allowEncodedSlash HTTP 服务器在解码编码斜杠期间抛出并捕获内部异常。默认情况下禁止斜杠解码:
