java - JSP Expression Language get parameter

Question

I am trying to get a String parameter "username" from the request with Expression Language. I've done some research, but couldn't find a way to do so, I would like something similar to ${pageContext.request.parameter.username}

How get a specific request parameter, using only expression language?

Answer 1

If get an attribute from 'session', try this ${username}.

If get an parameter from 'request', try this ${param.username}.
