Method for obtaining Model.addattribute () values in an El expression in the SSM framework

Recently in writing a graduation thesis with the SSM framework, found that the value of El expression can not be obtained, looked at some methods on the Internet found added <%@ page iselignored= "false"%> also no use.

After constantly groping to find a solution to the problem:

1. The @sessionattributes ("CurrentID") of the method inside the controller class is annotated with the name in parentheses and the Model.addattribute ("CurrentID",  Userresult.getuserid ()); The same name.

El expression: ${currentid}

That's all you can do.
