在不使用scriptlet的情况下引用JSP中的静态字段 [英] Reference static fields in JSP without using scriptlets

问题描述

可能重复：

来自EL的参考界面常量

所以我有一个JSP当前没有scriptlet，即没有出现<％（<％@除外），而是多次出现$ {javaVar}，即EL。

So I have a JSP that currently has no scriptlets in it, i.e. there are no occurrences of "<%" (with the exception of "<%@") and instead multiple occurrences of "${javaVar}", which is EL.

我现在需要添加如下内容：

I now need to add something like this:

<security:hasPermissionTo functionKey="<%= FunctionKeyConstants.CREATE %>" ... 

但我不想破坏这个JSP的约定。我可以用EL吗？或者其他任何建议？

But I don't want to break the convention of this JSP. Can I do this using EL? Or any other suggestions?

推荐答案

Java Class

Java Class

public class FunctionKeyConstants{
        public static final String NAME="Jigar";
        public String getNAME(){//NOTE THAT ITS NOT STATIC
             return NAME;
        }
}

JSP

<jsp:useBean id="cons" class="com.example.FunctionKeyConstants" scope="session"/>

然后

${cons.NAME}
