容器如何管理JSP、JSP的生命周期(七個階段)_jspInit()_jspService(HttpServletRequest,HttpServletResponse)_jspDestroy()

Servlet與JSP的相同點與不同點

JSP的組成:元素與模板數(shù)據(jù)標簽)

JSP腳本元素:

聲明:%!%

Scriplet:%%

腳本表達式:%=%

JSP注釋%----%!----///**/

JSP指令:%@pageimport=,contentType=pageEncoding=errorPage=err.jspisErrorPage=true|false......%

%@includefile=%靜態(tài)包含:包含另一個頁面的源代碼

%@taglibprefix=uri=%

JSP標準動作:jsp:includepage=urlflush=true/動態(tài)包含:包含另一個頁面的輸出

jsp:forwardpage=url/requestDispatcher.forwart(request,response);

jsp:paramname=keyvalue=value/

JavaBean規(guī)范:

1.公共類

2.實現(xiàn)序列化

3.公共的空構(gòu)造方法

4.屬性私有化，setters.....andgetters.....

jsp:useBeanid=class=scope=page|request|session|application/

jsp:setPropertyname=property=value=/jsp:setPropertyname=property=param=/jsp:setPropertyname=property=*/

jsp:getPropertyname=property=/

JSP九個內(nèi)置隱式對象:request、response、session、page、pageContext、application、config、out、exception

jsp:forwardpage=url

jsp:paramname=keyvalue=value/

/jsp:forward

jsp:includepage=xx.jspflush=true

jsp:paramname=keyvalue=value/

/jsp:include
