One: What is it:JSTL is the Apache extension to El expression, Jstl is the tag language! Jstl tag has been very convenient since its use, it is the same as the JSP action tag, but it is not a JSP built-in tag, we need to guide the package, as well as the designated tag library!Two: Why? What's the effect?JSP is mainly used to show the data results after the business logic code processing, the inevitable use of loops, Boolean logic, data format conversion and other statements, using JSTL can simp
