jsp内置对象与jsp域对象

Posted 2020-09-13 Legolas

自己回忆，好像是9个内置对象：

自己回忆	类	正确与否	正确答案
1.page	Page	错	page	Object(this)
2.pageContext	PageContext	对	2.pageContext	PageContext
3.request	HttpServletRequest	对	3.request	HttpServletRequest
4.session	HttpSession	对	4.session	HttpSession
5.out	printWriter	错	out	JspWriter
6.exception	Throwable	对	6.exception	Throwable
7.context	ServletContext	错	application	ServletContext
8.		错	response	HttpServletResponse
9.		错	config	ServletConfig

           

request	HttpServletRequest
response	HttpServletResponse
config	pageConfig
session	HttpSession
out	JspWriter
application	ServletContext
exception	Throwable
page	Object(this)
pageContext	PageContext

 

 

　　　　4个域对象

1.HttpServletRequest	request	Request域
2.HttpSession	session	Session域
3.ServletContext	context	Application域
4.PageContext	page	Page域
