Let's see a few examples.${test} will be translated into Only Sessionscope, Requestscope, etc. will be translated into getattribute ("xxx"), while other objects will be translated into getxxx ().El also supports arithmetic, logical operations, and syntax as in Java.

InIn the popular MVC open mode, JSP is only responsible for Data Rendering. the java code in JSP is a bit "cool" and the code is too messy, the combination of JSTL + EL effectively solves this problem. This article illustrates its role from the perspective of actual practice.

Take the jsp page title as an example:
To read multiple languages, you must put them in properties and return their values by reading the key corresponding to properties in the background. Then, the jsp page needs to introduce the class:
