JSP语法的xml表达

大家总是不喜欢看到<%和%>在jsp页面上,其实我们可以使用比较优雅的xml方式来表达
1 ,隐含的注释
JSP语法:<%--?内容?--%>
XML语法:无
2 ,变量或函数的声明
JSP语法:<%!?declaration; [ declaration; ] +...?%>
例如:
<%!?
??? int? i= 0 ; int? a,b,c;
??? Color?red= new? Color ( 255 , 0 , 0 ) ;
??? private?static?final? String?OK= "ok" ;
??? public? String?getAnswer (){
??????? return? OK;
??? }
%>
XML语法:
<jsp:declaration>
???? declartion; [ declaration; ] +...
</jsp:declaration>
例如:
<jsp:declaration>
??? int? i= 0 ; int? a,b,c;
??? Color?red= new? Color ( 255 , 0 , 0 ) ;
??? private?static?final? String?OK= "ok" ;
