[英]Creating a simple html server with Jersey and Java only
不知道为什么我很难找到一种使用Jersey制作简单Web服务器的方法。
public class AnotherJerseyHttpServer {
public static void main(String[] args) throws IOException {
System.out.println("Starting Crunchify's Embedded Jersey HTTPServer...\n");
HttpServer webServer = createHttpServer();
webServer.start();
System.out.println(String.format("\nJersey Application Server started with WADL available at " + "%sapplication.wadl\n", getURI()));
System.out.println("Started Crunchify's Embedded Jersey HTTPServer Successfully !!!");
}
public static HttpServer createHttpServer() throws IOException {
ResourceConfig rc = new PackagesResourceConfig("com.daford");
// This tutorial required and then enable below line: http://crunfy.me/1DZIui5
//rc.getContainerResponseFilters().add(CrunchifyCORSFilter.class);
return HttpServerFactory.create(getURI(), rc);
}
private static URI getURI() {
return UriBuilder.fromUri("http://" + sHostname() + "/").port(4444).build();
}
private static String sHostname() {
String hostName = "localhost";
try {
hostName = InetAddress.getLocalHost().getCanonicalHostName();
} catch (UnknownHostException e) {
e.printStackTrace();
}
return hostName;
}
}
和
@Path("api")
public class RestAPI {
@GET
@Produces(MediaType.TEXT_PLAIN)
public String get() {
return "this works";
}
}
而且我可以做http:// localhost:4444 / api并获得“ this works”。 现在,如何允许基于传入URL的html文件? 我获得了各种MediaType / mimi信息,但是我无法在线找到任何内容来告诉我如何仅基于传入URL返回文件。
假设您需要返回的文件打包在您的WAR文件中,则可以尝试以下解决方案:
@Path("/{fileName: .+}")
@Produces(MediaType.TEXT_HTML)
public class HtmlResource {
@GET
public Response getPage(@PathParam("fileName") String fileName) throws IOException {
URL url = Resources.getResource(fileName);
return Response.ok(Resources.toString(url, Charsets.UTF_8)).build();
}
}
@Path("/{fileName: .+}")
@Produces(MediaType.TEXT_HTML)
public class HtmlResource {
@GET
public Response getPage(@PathParam("fileName") String fileName) throws IOException {
InputStream stream = HtmlResource.class.getClassLoader()
.getResourceAsStream(fileName);
String responseContent = read(stream);
return Response.ok(responseContent).build();
}
private String read(InputStream stream) throws IOException {
try (BufferedReader buffer = new BufferedReader(new InputStreamReader(
stream, StandardCharsets.UTF_8))) {
return buffer.lines().collect(Collectors.joining("\n"));
}
}
}
例如, fileName
可以是assets/index.html
