public class InputServlet extends HttpServlet{ public void doGet(HttpServletRequest req,HttpServletResponse resp) throws ServletException,IOException{ String info = req.getParameter("info") ; // 假设参数名称为info PrintWriter out = resp.getWriter() ; out.println("<html>") ; out.println("<head><title>MLDNJAVA</title></head>") ; out.println("<body>") ; out.println("<h1>" + info + "</h1>") ; out.println("</body>") ; out.println("</html>") ; out.close() ; } public void doPost(HttpServletRequest req,HttpServletResponse resp) throws ServletException,IOException{ this.doGet(req,resp) ; } }
当一个servlet编译之后，需要在WEB-INF/web.xml中进行映射配置。
<servlet> <servlet-name>input</servlet-name> <servlet-class>com.alice.servlet.InputServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>input</servlet-name> <url-pattern>/inputservlet/InputServlet</url-pattern> </servlet-mapping>
现在的servlet是将其路径定义在根目录下的InputServlet
<form action="InputServlet" method="post"> 请输入内容：<input type="text" name="info"> <input type="submit" value="提交"> </form> </body> </html>
由于servlet是配置在根目录下，所以必须先向上一级目录之后才能找到所需要的servlet。
