Hello Joakim,
Thank you for the clarification. That is really helpful and I tried making
changes to my Gradle as follows:
plugins {
id 'java'
id "io.swagger.core.v3.swagger-gradle-plugin" version "2.1.9"
}
dependencies {
testImplementation 'org.junit.jupiter:junit-jupiter-api:5.6.0'
testRuntimeOnly 'org.junit.jupiter:junit-jupiter-engine'
compile 'org.eclipse.jetty:jetty-server:11.0.0'
compile 'org.eclipse.jetty:jetty-util:11.0.0'
compile 'org.springframework.data:spring-data-redis:1.8.0.RELEASE'
compile 'redis.clients:jedis:3.5.2'
// https://mvnrepository.com/artifact/org.json/json
compile group: 'org.json', name: 'json', version: '20201115'
compile group: 'org.eclipse.jetty', name: 'jetty-servlet', version: '11.0.0'
compile group: 'io.swagger.core.v3', name:
'swagger-jaxrs2-jakarta', version: '2.1.9'
compile group: 'io.swagger.core.v3',
name:'swagger-jaxrs2-servlet-initializer-v2-jakarta', version: '2.1.9'
// compile group: 'io.swagger', name: 'swagger-jersey2-jaxrs',
version: '1.6.2'
}
The reason for using swagger-jaxrs2-jakarta is that I want to use OpenAPI 3
and according to the documentation here swagger-core-help-page
<https://github.com/swagger-api/swagger-core/wiki/Swagger-2.X---Getting-started>
,
from Swagger-core v2.1.9 they are supporting jakarta namespace.
But when I add dependencies in my jetty server based on above, I am not
able to see the swagger.json. Is anything wrong with my way of adding
dependencies in code below -
import com.cloudian.hfs.handlers.FeatureGroupsHandler;
import com.cloudian.hfs.handlers.FeatureStoreHandler;
import com.cloudian.hfs.handlers.RecordsHandler;
import com.cloudian.hfs.handlers.StreamingHandler;
import jakarta.servlet.Servlet;
import org.eclipse.jetty.server.HttpConfiguration;
import org.eclipse.jetty.server.HttpConnectionFactory;
import org.eclipse.jetty.server.Server;
import org.eclipse.jetty.server.ServerConnector;
import org.eclipse.jetty.server.handler.ContextHandler;
import org.eclipse.jetty.server.handler.ContextHandlerCollection;
import org.eclipse.jetty.servlet.ServletContextHandler;
import org.eclipse.jetty.servlet.ServletHolder;
import org.eclipse.jetty.util.thread.QueuedThreadPool;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.InputStream;
import java.util.Properties;
public static void main(String[] args) throws Exception {
System.out.println("StartHFS");
initProperties();
// Create and configure a ThreadPool.
QueuedThreadPool threadPool = new QueuedThreadPool();
threadPool.setName("server");
// Create a Server instance.
Server server = new Server(threadPool);
// HTTP configuration and connection factory.
HttpConfiguration httpConfig = new HttpConfiguration();
HttpConnectionFactory http11 = new HttpConnectionFactory(httpConfig);
// Create a ServerConnector to accept connections from clients.
ServerConnector connector = new ServerConnector(server, 1, 1, http11);
connector.setPort(8080);
connector.setHost("0.0.0.0");
connector.setAcceptQueueSize(128);
server.addConnector(connector);
// Swagger Setup for Embedded Jetty Server
ServletContextHandler servletContextHandler = new
ServletContextHandler(ServletContextHandler.SESSIONS);
servletContextHandler.setContextPath("/");
server.setHandler(servletContextHandler);
// Setup API resources
ServletHolder apiServlet =
servletContextHandler.addServlet(Servlet.class, "/api/*");
apiServlet.setInitOrder(1);
apiServlet.setInitParameter("com.sun.jersey.config.property.packages",
"com.api.resources;io.swagger.jakarta.json;io.swagger.jakarta.listing");
// Setup Swagger Servlet
ServletHolder swaggerServlet =
servletContextHandler.addServlet("DefaultJakartaConfig.class",
"/swagger-core");
swaggerServlet.setInitOrder(2);
swaggerServlet.setInitParameter("api.version", "1.0.0");
addHandlers(server);
// Start the Server so it starts accepting connections from clients.
server.start();
server.join();
System.out.println("StartHFS DONE");
}
Best,
Aniruddha
