在 eclipse 中我创建了一个名为 Hello 的动态 Web 项目，然后创建了一个名为 Good 的 serverlet，编译运行，完全正常。代码如下：
package Hello; import java.io.IOException; import javax.servlet.ServletException; import javax.servlet.annotation.WebServlet; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; /** * Servlet implementation class Good */ @WebServlet("/Good") public class Good extends HttpServlet { private static final long serialVersionUID = 1L; /** * @see HttpServlet#HttpServlet() */ public Good() { super(); // TODO Auto-generated constructor stub } /** * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response) */ protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { // TODO Auto-generated method stub response.getWriter().append("Served at: ").append(request.getContextPath()); } /** * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response) */ protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { // TODO Auto-generated method stub doGet(request, response); } /** * @see HttpServlet#doPut(HttpServletRequest, HttpServletResponse) */ protected void doPut(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { // TODO Auto-generated method stub } /** * @see HttpServlet#doDelete(HttpServletRequest, HttpServletResponse) */ protected void doDelete(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { // TODO Auto-generated method stub } }我是在Win7环境下运行的，在路径
C:\Users\Administrator\workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\Hello找到 eclipse 临时部署的文件，把 Hello 文件夹复制到 centOS 的 /var/lib/tomcat/webapps 路径下即可。 输入 http://101.200.56.209:8080/Hello/Good 即可看到结果。
OK，到此为止，我已经知道在 centOS 服务器下用 java 开发 web 项目的套路了。我的目标是开发一个REST API 形式的后台服务系统，现在已经具备最近本的知识了，再了解一下 MySQL 的用法，就可以动手开始干活了。
