简单实现登录重定向

loin.jsp界面

<html>
<body>
<h2>Hello World!</h2>
<%--这里的提交路径，需要寻找到项目的路径--%>
<%--${pageContext.request.contextPath}代表当前的项目--%>
<form action="${pageContext.requset.contexPath}/login" method="get">
    用户名：<input type="text" name="username"><br>
    密码：<input type="password" name="password"><br>
    <input type="submit" value="登录">
</form>
</body>
</html>

Servlet

public class RequestTest extends HttpServlet {
    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        System.out.println("请求到了这个页面");
        resp.setCharacterEncoding("utf-8");
        req.setCharacterEncoding("utf-8");
        String username = req.getParameter("username");
        String password = req.getParameter("password");

        //重定向
        resp.sendRedirect("/response_war/success.jsp");
    }

    @Override
    protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        doGet(req, resp);
    }
}

web.xml配置

  <servlet>
    <servlet-name>requset</servlet-name>
    <servlet-class>com.kuang.servlet.RequestTest</servlet-class>
  </servlet>
  <servlet-mapping>
    <servlet-name>requset</servlet-name>
    <url-pattern>/login</url-pattern>
  </servlet-mapping>
