Jetty具有嵌入各种应用程序的丰富历史。 在本节中，我们将向您介绍我们的git存储库中的embedded-jetty-examples项目下的一些简单示例。

重要：生成此文档时，将直接从我们的git存储库中提取这些文件。 如果行号不对齐，请随时在github中修复此文档，并向我们提供拉取请求，或者至少打开一个问题以通知我们该差异。

简单的文件服务器

此示例显示如何在Jetty中创建简单文件服务器。 它非常适合需要实际Web服务器来获取文件的测试用例，它可以很容易地配置为从src / test / resources下的目录提供文件。 请注意，这在文件缓存中没有任何逻辑，无论是在服务器内还是在响应上设置适当的标头。 它只是几行，说明了提供一些文件是多么容易。

public classFileServer
{public static void main(String[] args) throwsException{//Create a basic Jetty server object that will listen on port 8080.  Note that if you set this to port 0//then a randomly available port will be assigned that you can either look in the logs for the port,//or programmatically obtain it for use in test cases.Server server = new Server(8080);//Create the ResourceHandler. It is the object that will actually handle the request for a given file. It is//a Jetty Handler object so it is suitable for chaining with other handlers as you will see in other examples.ResourceHandler resource_handler = newResourceHandler();//Configure the ResourceHandler. Setting the resource base indicates where the files should be served out of.//In this example it is the current directory but it can be configured to anything that the jvm has access to.resource_handler.setDirectoriesListed(true);resource_handler.setWelcomeFiles(new String[]{ "index.html"});resource_handler.setResourceBase(".");//Add the ResourceHandler to the server.HandlerList handlers = newHandlerList();handlers.setHandlers(new Handler[] { resource_handler, newDefaultHandler() });server.setHandler(handlers);//Start things up!

server.start();server.join();}
}

启动后你应该可以导航到http：// localhost：8080 / index.html（假设一个在资源库目录中）。

Maven坐标

要在项目中使用此示例，您需要声明以下Maven依赖项。

<dependency><groupId>org.eclipse.jetty</groupId><artifactId>jetty-server</artifactId><version>${project.version}</version>
</dependency>

Split File Server

此示例构建在简单文件服务器上，以显示如何将多个ResourceHandler链接在一起可以聚合多个目录以在单个路径上提供内容，以及如何将这些目录与ContextHandler链接在一起。

server.start();//Dump the server state
System.out.println(server.dump());//The use of server.join() the will make the current thread join and//wait until the server is done executing.//Seehttp://docs.oracle.com/javase/7/docs/api/java/lang/Thread.html#join()
server.join();}
}

启动后，你应该可以导航到http：// localhost：8090 / index.html（假设一个在资源库目录中），你可以正常访问。 任何文件请求都将在第一个资源处理程序中查找，然后在第二个资源处理程序中查找，依此类推。

Maven Coordinates

要在项目中使用此示例，您需要声明以下maven依赖项。 我们建议您不要在实际应用程序中使用工具链依赖项。

<dependency><groupId>org.eclipse.jetty</groupId><artifactId>jetty-server</artifactId><version>${project.version}</version>
</dependency>
<dependency><groupId>org.eclipse.jetty.toolchain</groupId><artifactId>jetty-test-helper</artifactId><version>2.2</version>
</dependency>
