基于Spring MVC的简单HelloWorld实例

1 首先架构jetty,将相关包导入后

public class ServerMain {
private static final String CONFIG_LOCATION = "com.easysoft.cn.config";
private static final String MAPPING_URL = "/*";
private static final String DEFAULT_PROFILE = "dev";

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

Server server = new Server(8090);

ServletContextHandler context = new ServletContextHandler(ServletContextHandler.SESSIONS);
context.setContextPath("/MyServer");   //这里是请求的上下文，比如http://localhost:8090/MyServer
server.setHandler(context);

WebApplicationContext applicationContext=getContext();
//        context.addServlet(new ServletHolder(new HelloWorld()), "/helloWorld");   //添加servlet，第一是具体的servlet，后面是请求的别名，在http请求中的路径
//        context.addServlet(new ServletHolder(new HelloWorld("chan")), "/HellworldWithParams");

//        context.addServlet(new ServletHolder(new DispatcherServlet( applicationContext)), MAPPING_URL);
//        context.addEventListener(new ContextLoaderListener(applicationContext));
//        context.setResourceBase(new ClassPathResource("webapp").getURI().toString());

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

2 新建servlet

public class HelloWorld extends HttpServlet {

/**
* serialVersionUID
*/
private static final long serialVersionUID = 2271797150647771294L;

private String msg = "hello world~~~~~~";

public HelloWorld() {
}

public HelloWorld(String msg){
this.msg = msg;
}

@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
doPost(req, resp);
}

@Override
protected void doPost(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
String userName = req.getParameter("userName");
String password = req.getParameter("password");
resp.setCharacterEncoding("UTF-8");
resp.setContentType("text/html");
resp.setStatus(HttpServletResponse.SC_OK);
PrintWriter pWriter = resp.getWriter();
pWriter.println("<h1>" + msg + "</h1>");
pWriter.println("测试中文信息:" + req.getSession(true).getId());
pWriter.println("<h3>用户信息:" + userName + "</h3>");
pWriter.println("<h3>用户密码:" + password + "</h3>");
}
}

完了之后，在浏览器中输入http://localhost:8090/MyServer/helloWorld?userName=zhangsan&password=123，得到的结果如下：  

hello world~~~~~~  
  
测试中文信息:haybcp922h6x1v8bh9xeazx96  
用户信息:zhangsan  
  
用户密码:123 

测试jetty安装完毕 可以连接通jetty和servlet
