Accessing Java Constants from JSTL or OGNL
Accessing Java Constants from JSTL
Even there could be many variations to the above code, more creative, funnyer or smarter, this is not my recommended solution. Following the Principle No. 6 from our internal guide, the “DRW concept” (don’t reinvent the wheel :) ), the solution is simple: the unstandard tag library from Apache. Here’s how to use it: and later in you code, an expression like: ${users[Constants.NAME]}
and later in you code, an expression like:
${users[Constants.NAME]}
OGNL - Getting Static Fields
Getting Static Fields
You can refer to a static field using the syntax @class@field. The class must be fully qualified.
用appfuse的方法使用常量定義ConstantsTag, constants.tld
然後在使用的時候
在header.jsp中
然後在使用的地方
