eclipse+tomcat+httpServlet初学

1.在eclipse中配置tomcat，参考上一边文章，建立的web项目tomcatWeb目录结构

2.添加Servlet处理类

3. 实现doGet()与doPost()方法：

public class HttpServletDemo extends HttpServlet {

	/**
	 * 
	 */
	private static final long serialVersionUID = 4230239235404655360L;

	public void doGet(HttpServletRequest request, HttpServletResponse response)
			throws IOException {
		response.setContentType("text/html;charset=GB2312");
		PrintWriter printWriter = response.getWriter();
		// printWriter.print("hello, china");
		String title = "HelloServlet";
		String heading1 = "HelloServlet的doGet方法的输出：";
		printWriter = response.getWriter();
		printWriter.print("");
		printWriter.print("");
		printWriter.print(heading1);
		printWriter.println("
:您好
");
		printWriter.print("");
		printWriter.write("");
		printWriter.flush();
		printWriter.close();
	}

	public void doPost(HttpServletRequest request, HttpServletResponse response)
			throws IOException {
		doGet(request, response);
	}
}

4. 在web.xml中配置servlet

 
    TomcatWeb
    tomcat.servlet.HttpServletDemo
  

  
    TomcatWeb
    /servlet/HttpServletDemo
  

5. 用配置好的tomcat容器运行该web项目

方式1：右击项目--run as - run on server - 选择配置好的tomcat容器

方式2：右击运行

6. 在浏览器上输入：http://localhost:8080/TomcatWeb/servlet/HttpServletDemo，即可看到
