在几个java IDE中，IntelliJ IDEA应该是最养眼的了，不过免费的社区版不能配置web服务器，所以拿来开发servlet感觉困难重重。经过一番探索，终于闯出了一条便捷的路。快速编码，运行，调试都没问题，我所使用的版本是14.0.1。下面就来介绍一下。
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.io.PrintWriter;
public class MainServlet extends HttpServlet {
/**
* 处理get或post请求
*
* @param request
* @param response
* @throws javax.servlet.ServletException
* @throws java.io.IOException
*/
protected void processRequest(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html;charset=UTF-8");
PrintWriter out = response.getWriter();
out.println("Servlet MainServlet.");
}
// <editor-fold defaultstate="collapsed" desc="HttpServlet 内部处理方法">
@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
processRequest(request, response);
}
@Override
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
processRequest(request, response);
}
@Override
public String getServletInfo() {
return "Short description";
}
// </editor-fold>
}
import org.eclipse.jetty.server.Server;
import org.eclipse.jetty.servlet.ServletContextHandler;
import org.eclipse.jetty.servlet.ServletHolder;
public class Main {
// 端口
private static final int PORT=8090;
// 根路径
private static final String contextPath="/demo";
public static void main(String[] args) throws Exception {
// 建立jetty服务器
Server server=new Server(PORT);
ServletContextHandler context=new ServletContextHandler(ServletContextHandler.SESSIONS);
context.setContextPath(contextPath);
server.setHandler(context);
// 添加servlet，可添加多个
context.addServlet(new ServletHolder(new MainServlet()),"/Main");
// 启动服务器
server.start();
server.join();
}
}
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.1" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd">

#if (${PACKAGE_NAME} && ${PACKAGE_NAME} != "")package ${PACKAGE_NAME};#end
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.io.PrintWriter;
/**
* Created by ${USER} on ${YEAR}-${MONTH}-${DAY} ${HOUR}:${MINUTE}.
*/
public class ${NAME} extends HttpServlet {
/**
* 处理get或post请求
*
* @param request
* @param response
* @throws javax.servlet.ServletException
* @throws java.io.IOException
*/
protected void processRequest(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html;charset=UTF-8");
PrintWriter out = response.getWriter();
out.println("Servlet ${NAME}.");
}
// <editor-fold defaultstate="collapsed" desc="HttpServlet 内部处理方法">
@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
processRequest(request, response);
}
@Override
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
processRequest(request, response);
}
@Override
public String getServletInfo() {
return "Short description";
}
// </editor-fold>
}
到此，整个过程完成了，不过你不要被这么长的步骤吓着，其实很多都是基础，重点也就是如何嵌入jetty而已。
