java - 我有 Java rest api 异常 java.lang.IllegalArgumentException

Question

我在intellij中创建了一个rest api项目java。 当我运行我的项目时，我收到异常

这是我的主类代码:

import com.sun.jersey.api.container.httpserver.HttpServerFactory;
import com.sun.jersey.api.core.PackagesResourceConfig;
import com.sun.jersey.api.core.ResourceConfig;
import com.sun.net.httpserver.HttpServer;


public class Main {
    public static void main(String[] args) throws Exception {

            ResourceConfig config = new PackagesResourceConfig("controller");
            HttpServer server = HttpServerFactory.create("http://localhost:8070/",config);
            server.start();

    }
}

这是我的计算器类代码:

package controller;

import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.QueryParam;

@Path("/cal")
public class Calculator {
    @Path("/sum")
    @POST
    @Produces("text/plain")
    public String sum(@QueryParam("p1") String x,@QueryParam("p2") String y)
    {
        return String.valueOf(Integer.parseInt(x)+Integer.parseInt(y));
    }
}

请帮助我
