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. 0. EL:In JSP, you can extract objects from the context and output simplified languages

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: Public class extends extconfig {private static Properties properties = null; // read the properties resource file private static long lastModified = 0; // The last modi

For the servlet that inherits this class, it should be noted that the "standard" getparameter cannot read the post Data, because the data is already read from the ServletInputStream in this class. So we should make Use the GetParameter method provided in this class. The rest is the output problem, we want to transfer the output of the information to the UTF8 of the binary stream output.
