取出session中的所有值

/获取

sessionHttpSession session = request.getSession();

//获取键名String[] names = session.getValueNames();

//循环遍历 for (int i = 0; i < names.length; i++) {

//打印 out.println(names[i] + “: ” + session.getValue(names[i]) + “
”);

}

最简形式

//形式一
sessionHttpSession session = request.getSession();

String[] names = session.getValueNames();

for (int i = 0; i < names.length; i++) {

System.out.println(names[i] + “±–+” + session.getValue(names[i]).toString());

}

//形式二
String[] names = request.getSession().getValueNames();

for (int i = 0; i < names.length; i++) {

System.out.println(names[i] + “±–+” + request.getSession().getValue(names[i]).toString() );

}
