session对象能不能传数组?
String[] a = {"1","2","3"};
session.putAttribute("test",a);
String[] b = new String[3];
session.getAttribute("test",b);
以上语法有问题吗?
String[] a = {"1","2","3"};
session.putAttribute("test",a);
String[] b = new String[3];
session.getAttribute("test",b);
以上语法有问题吗?

可以,取:String [] b = (String[])session.getAttribute("test");
|
呵呵,当然可以传了。

String[] b = (String[])session.getAttribute("test");

API如是说到:
HttpSession
public void setAttribute(java.lang.String name,
java.lang.Object value)Binds an object to this session, using the name specified. If an object of the same name is already bound to the session, the object is replaced.
After this method executes, and if the object implements HttpSessionBindingListener, the container calls HttpSessionBindingListener.valueBound.
Parameters:
name - the name to which the object is bound; cannot be null
value - the object to be bound; cannot be null
由此看来是不行,他需要的对象是一个OBJECT的,不是String[]的.
