General web Landing, the simplest is the user name and password, but the user may not follow the correct format to enter the resulting SQL query will be triggered, but this kind of query will greatly increase the burden on the site. To avoid such problems, we can use the STRUTS2 validator to accomplish the results we want.Let's say we have a form like this:User name: Password: now we need to set the calibration configuration, generally in the developm

Collections. Generic;3 using System. L
With the application of the orm framework, development is more object-oriented, and there is no need to design a database specifically, instead of writing entities and object ing.
Therefore, entity writing is a very basic and important task. Do not drag your development work back when you do it. For example, to verify the validity of data, we are used to doing it in action or controller. In fact, this work can be done in advance in entity.
