它们三个是Servlet中可以使用的域对象,而JSP中可以多使用一个域对象,明天我们再讲解JSP的第四个域对象。 l HttpServletRequest:一个请求创建一个request对象,所以在同一个请求中可以共享request,例如一个请求从AServlet转发到BServlet,那么AServlet和BServlet可以共享request域中的数据; l ServletContext:一个应用只创...
public Object getSession(HttpServletRequest request) { HttpSession session = request.getSession(false); String id = session.getId(); System.out.println("获取Session sessionid:信息" + session.getId()); Object value = session.getAttribute("name"); ...
Object msg = session.getAttribute("msg"); System.out.println(msg); 1. 2. 3. 4. *移除session HttpSession session = req.getSession(); System.out.println("Demo03Servlet" +session.getId()); session.removeAttribute("msg"); 1. 2.
HttpServletRequest // 获取session对象HttpSessiongetSession() HttpSession // 在session中保存数据voidsetAttribute(String name, Object value)// 从session中获取数据。注意:返回值是Object,因此需要将返回值强制转换才能方便使用ObjectgetAttribute(String name)// 从session中移除数据voidremoveAttribute(String name) ...
说明:下面出现的Session是Tomcat内定义的一个接口,而我们通常所说的Session,是jakarta.servlet.http(或java.servlet.http)中定义的HttpSession接口,在Tomcat中它们有一个共同的实现类为StandardSession,通过门面模式,最终实际操作的都是StandardSession对象。 在Tomcat中,主要由ManagerBase负责维护Session对象,源码如下,可以看...

According to the Java Servlet API, which WebLogic Server implements and supports, each servlet can access a server-side session by using itsHttpSessionobject. You can access anHttpSessionobject in theservice()method of the servlet by using theHttpServletRequestobject with the variablerequestvariable...
