1、第一步：新建一个javaweb项目。打开myeclipse file --》new--》web project具体操作如下图所示：
2、第二步：编写代码。1、主要是写一个普通的java类然后集成import javax.ser箪滹埘麽vlet.http.HttpServletpacka爿讥旌护ge com.test.servlet;import java.io.IOException;import javax.servlet.ServletException;import javax.servlet.http.HttpServlet;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;public class UserServlet extends HttpServlet { private static final long serialVersionUID = 1L; public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { this.doPost(request, response); } public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { String sex = request.getParameter("sex"); String[] bobby = request.getParameterValues("bobby"); //new String(sex.getBytes("ISO-8859-1"),"utf-8"); 解决前端乱码 System.out.println("性别 :"+new String(sex.getBytes("ISO-8859-1"),"utf-8")); for (int i = 1; i <= bobby.length; i++) { System.out.println("爱好"+i+" :"+new String(bobby[i-1].getBytes("ISO-8859-1"),"utf-8")); } }}
3、第三步：配置servlet的映射。servlet的映射主要是通过servlet\WebRoot\WEB-INF\web.xmld 配置主要分为两部分1、配置一个servlet名字并指向处理类 <servlet> <servlet-name>userServlet</servlet-name> <servlet-class>com.test.servlet.UserServlet</servlet-class> </servlet>2、配置一个前台拦截请求的URL对应一个servlet名字 <servlet-mapping> <servlet-name>userServlet</servlet-name> <url-pattern>/userServlet.do</url-pattern> </servlet-mapping>3、编写一个前台的简单调用。
4、第四步：测试项目。1、在谷歌浏览器中输入地址打开项目2、填写测试数据
