在独立的java程序中使用jetty

在独立的java程序中，不使用tomcat，如何产生HTTP请求呢？可以使用jetty

jetty官网: http://www.eclipse.org/jetty/documentation/current/embedding-jetty.html

1.使用jetty，需要引入jar包
maven项目中，在pom.xml添加如下内容：

<!-- jetty -->    <dependency>        <groupId>org.eclipse.jetty</groupId>        <artifactId>jetty-server</artifactId>        <version>9.4.8.v20171121</version>    </dependency>    <!-- https://mvnrepository.com/artifact/org.eclipse.jetty/jetty-servlet -->    <dependency>        <groupId>org.eclipse.jetty</groupId>        <artifactId>jetty-servlet</artifactId>        <version>9.4.8.v20171121</version>    </dependency>

2.参考示例

import java.io.IOException;import javax.servlet.ServletException;import javax.servlet.http.HttpServlet;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.eclipse.jetty.server.Server;import org.eclipse.jetty.servlet.ServletHandler;public class MinimalServlets{    public static void main( String[] args ) throws Exception    {        // 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);        // The ServletHandler is a dead simple way to create a context handler        // that is backed by an instance of a Servlet.        // This handler then needs to be registered with the Server object.        ServletHandler handler = new ServletHandler();        server.setHandler(handler);        // Passing in the class for the Servlet allows jetty to instantiate an        // instance of that Servlet and mount it on a given context path.        // IMPORTANT:        // This is a raw Servlet, not a Servlet that has been configured        // through a web.xml @WebServlet annotation, or anything similar.        handler.addServletWithMapping(HelloServlet.class, "/hello");        // Start things up!        server.start();        // The use of server.join() the will make the current thread join and        // wait until the server is done executing.        // See        // http://docs.oracle.com/javase/7/docs/api/java/lang/Thread.html#join()        server.join();    }    @SuppressWarnings("serial")    public static class HelloServlet extends HttpServlet    {        @Override        protected void doGet( HttpServletRequest request,                              HttpServletResponse response ) throws ServletException,                                                            IOException        {            response.setContentType("text/html");            response.setStatus(HttpServletResponse.SC_OK);            response.getWriter().println("<h1>Hello from HelloServlet</h1>");        }    }}

3.访问
本地运行程序，可以访问：http://localhost:8080/hello
