我正在尝试在 RESTlet 上运行第一个服务器教程 docs但是即使我将 jars 添加到我的类路径中，我也会收到错误。我添加了 org.reSTLet.jar 和 org.reSTLet.ext.*
服务器的代码是:
package test;
import org.restlet.Server;
import org.restlet.data.Protocol;
import org.restlet.resource.Get;
import org.restlet.resource.ServerResource;
public class Test extends ServerResource {
public static void main(String[] args) throws Exception {
// Create the HTTP server and listen on port 8182
new Server(Protocol.HTTP, 8182, Test.class).start();
}
@Get
public String toString() {
return "hello, world";
}
}
我得到的错误是:

关于reSTLet - 运行 RESTlet 教程，我收到 java.lang.NoClassDefFoundError，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/4653040/
