三.测试

1.使用后台进行验证，在Test下建立class名为testlogin，使用debug验证

代码如下：

package Test;import swsm.news.biz.NewsUserBiz;import swsm.news.entity.NewsUser;import swsm.news.iface.INewsUserBiz;public class testlogin {    public static void main(String args[]){        INewsUserBiz ubiz = new NewsUserBiz();        NewsUser user = ubiz.doLogin("张三", "888888");        System.out.println(user);    }}

2.使用jsp验证，在index.jsp下body内插入以下代码

 <form action="${pageContext.request.contextPath}/LoginValidate" method="get">       <p>用户名：<input type='text' name='un' placeholder='请输入用户名' /></p>       <p>密码：<input type='password' name='pwd' placeholder ="密码"/></p>       <input type='submit' value='登陆'>    </form>

3.在swsm.news.control创建sevlet类名为：LoginValidate

代码为：

package swsm.news.control;import java.io.IOException;import java.io.PrintWriter;import javax.servlet.ServletException;import javax.servlet.http.HttpServlet;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import swsm.news.biz.NewsUserBiz;import swsm.news.entity.NewsUser;import swsm.news.iface.INewsUserBiz;public class LoginValidate extends HttpServlet {    public void doGet(HttpServletRequest request, HttpServletResponse response)            throws ServletException, IOException {        doPost(request, response);    }    public void doPost(HttpServletRequest request, HttpServletResponse response)            throws ServletException, IOException {        String username = new String(request.getParameter("un").getBytes("ISO-8859-1"),"utf-8");        String password = request.getParameter("pwd");        System.out.println(username+password);        INewsUserBiz ubiz = new NewsUserBiz();        NewsUser user = ubiz.doLogin(username, password);        if(user!=null){            System.out.println("登录成功");            //response.sendRedirect("LoginSuccess.jsp");        }else{            System.out.println("登录失败");        }    }}

4.部署web项目在jsp页面输入用户名密码，然后再console看测试结果。
