Servlet和jsp运用session

HttpSession session=request.getSession();

session.setAttribute("sessions", session);

response.sendRedirect("***.jsp");

在****.jsp中通过sessions取到session对象；

<ahref="在web.xml中配置 sess?name=${一个对象 }">你好</a>

?模拟传值

web.xml配置

<servlet>
  <servlet-name>sess</servlet-name>
  <servlet-class>****.sess</servlet-class>
  </servlet>
    <servlet-mapping>
  <servlet-name>sess</servlet-name>
  <url-pattern>/sess</url-pattern>
  </servlet-mapping>

对象属性若是字符串

String name=requst.getParameter("name");
