我有一个测试用例来测试 jersey 2.x 休息服务。但得到了 NullPointerException 。在我看来，jsr311 和 javax.ws.rs-api 之间存在 jar 问题。我没有找到任何具有任何依赖关系的 jsr311.. 不知道为什么 servlet 正在引用 jsr311.jar

以下是我的代码更改

HelloWorldServiceTest.java

package test;

import static org.junit.Assert.assertEquals;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.core.Application;

import org.glassfish.jersey.server.ResourceConfig;
import org.glassfish.jersey.servlet.ServletContainer;
import org.glassfish.jersey.test.DeploymentContext;
import org.glassfish.jersey.test.JerseyTest;
import org.glassfish.jersey.test.ServletDeploymentContext;
import org.glassfish.jersey.test.ServletDeploymentContext.Builder;
import org.glassfish.jersey.test.grizzly.GrizzlyWebTestContainerFactory;
import org.glassfish.jersey.test.spi.TestContainerException;
import org.glassfish.jersey.test.spi.TestContainerFactory;
import org.junit.Test;

import com.mkyong.rest.HelloWorldService;

import rest.RestApplication;

public class HelloWorldServiceTest extends JerseyTest{

    @Path("hello")
    public static class HelloResource {
        @GET
        public String getHello() {
            return "Hello World!";
        }
    }



    @Override
    protected Application configure() {
        // TODO Auto-generated method stub

        return new ResourceConfig(HelloWorldService.class );
    }

    @Override
    protected TestContainerFactory getTestContainerFactory() throws TestContainerException {
        return new GrizzlyWebTestContainerFactory();
    }

    @Override
    protected ServletDeploymentContext configureDeployment() {
        return ServletDeploymentContext.forPackages(HelloWorldService.class.getPackage().getName()).build();
        //return ServletDeploymentContext.forServlet(new ServletContainer(new ResourceConfig(HelloWorldService.class))).build();
    }

    @Test
    public void testSingleNode() throws Exception {
        final String hello = target("hello").path("Test").request().get(String.class);
        System.out.println("Response"+ hello);
        assertEquals("Jersey say : Test", hello);
    }
    }

下面是我得到的例外
