韩陆，你好你的书，麻烦写的清楚一点，多写一些，也许还能多点稿费。小韩，写书认真一点。第13页上来就用maven命令行创建项目，这就有问题啊，没有pom.xml文件mvn这个命令怎么跑的起来呢？所以正确的过程是这样的：eclipse上创建项目创建的结果是这样的：创建过程，先创建一个maven项目 然后archetypes选择书中指出的jersey-quickstart-grizzly2创建项目之后，实际上会报错默认情况下eclipse创建出来的pom.xml文件中提供的jersey-version的版本是1.20但实际上mavenrepository上提供的最新版也就是1.19.4，所以修改一下正常情况下，创建项目完毕，我们测试一下：首先当然是参考书中的命令行方式，用curl这个命令去执行，这需要首先下载配置curlhttps://curl.haxx.se/windows/配置环境变量现在都准备好了我们先看看这个项目的内容，它都自动帮我们生成了什么：MyResource.java package my.restfulwork.jerseyone; import javax.ws.rs.GET; import javax.ws.rs.Path; import javax.ws.rs.Produces; // The Java class will be hosted at the URI path "/myresource" @Path("/myresource") public class MyResource { // TODO: update the class to suit your needs // The Java method will process HTTP GET requests @GET // The Java method will produce content identified by the MIME Media // type "text/plain" @Produces("text/plain") public String getIt() { return "Got it!"; } } Main.java package my.restfulwork.jerseyone; import com.sun.jersey.api.container.grizzly2.GrizzlyServerFactory; import com.sun.jersey.api.core.PackagesResourceConfig; import com.sun.jersey.api.core.ResourceConfig; import org.glassfish.grizzly.http.server.HttpServer; import javax.ws.rs.core.UriBuilder; import java.io.IOException; import java.net.URI; public class Main { private static int getPort(int defaultPort) { //grab port from environment, otherwise fall back to default port 9998 String httpPort = System.getProperty("jersey.test.port"); if (null != httpPort) { try { return Integer.parseInt(httpPort); } catch (NumberFormatException e) { } } return defaultPort; } private static URI getBaseURI() { return UriBuilder.fromUri("http://localhost/").port(getPort(9998)).build(); } public static final URI BASE_URI = getBaseURI(); protected static HttpServer startServer() throws IOException { ResourceConfig resourceConfig = new PackagesResourceConfig("my.restfulwork.jerseyone"); System.out.println("Starting grizzly2..."); return GrizzlyServerFactory.createHttpServer(BASE_URI, resourceConfig); } public static void main(String[] args) throws IOException { // Grizzly 2 initialization HttpServer httpServer = startServer(); System.out.println(String.format("Jersey app started with WADL available at " + "%sapplication.wadl\nHit enter to stop it...", BASE_URI)); System.in.read(); httpServer.stop(); } } MainTest.java package my.restfulwork.jerseyone; import org.glassfish.grizzly.http.server.HttpServer; import com.sun.jersey.core.header.MediaTypes; import com.sun.jersey.api.client.Client; import com.sun.jersey.api.client.WebResource; import junit.framework.TestCase; public class MainTest extends TestCase { private HttpServer httpServer; private WebResource r; public MainTest(String testName) { super(testName); } @Override protected void setUp() throws Exception { super.setUp(); //start the Grizzly2 web container httpServer = Main.startServer(); // create the client Client c = Client.create(); r = c.resource(Main.BASE_URI); } @Override protected void tearDown() throws Exception { super.tearDown(); httpServer.stop(); } /** * Test to see that the message "Got it!" is sent in the response. */ public void testMyResource() { String responseMsg = r.path("myresource").get(String.class); assertEquals("Got it!", responseMsg); } /** * Test if a WADL document is available at the relative path * "application.wadl". */ public void testApplicationWadl() { String serviceWadl = r.path("application.wadl"). accept(MediaTypes.WADL).get(String.class); assertTrue(serviceWadl.length() > 0); } } 上述三个文件是项目自己生成的java代码我们运行Main.javaconsole中的信息如下所示： 我们使用cmd客户端，执行命令行语句：执行结果，和书中写的一样。

运行java web项目时，出现了这个错误。com.sun.jersey.api.container.ContainerException: The ResourceConfig instance does not contain any root resource classes.奇怪的是，这个错误有时候出现，有时候不出现。Jersey的配置信息 也没写错啊。还有可能是什么原因呢。
