The simple Factory mode is also called the Static factory method pattern, and the main function is to instantiate (create) objects of each class through a simple factory class, without having to instantiate the object through new. The advantage is that the factory class contains certain logical judgments that dynamically instantiate related classes based on the client's selection criteria. The downside is t

Features: 1: The amount of code is small, and the learning cost is low; 2: The default jsp syntax TAG method. jsp-related users can directly write templates Based on jsp syntax; 3: use nativ

" command will be executed, such: Myisamchk-o phpbb2_users.MYI This action may take 2 ~ 3 times until no error message appears! After repair, after restarting the MySQL service, you can use the mysql client command to Query the database content and test whether it is normal. fortunately, the database works normally at this time. Of course, before you back up the data, it would be better to check whether the data is correct first. If necessary, you can schedule the detection before the backup, bu

before explaining the simple factory pattern, it is necessary to understand some of the principles of OO NBSP;1.OCP (opening and closing principles, open-closed principle): A software entity should be open to extension and closed to modifications. That is, for an existing software, if it needs to be extended, it should be done on the basis that there is no need to modify the existing code. 2.DIP (relying on the reverse principle, dependence inver

If you define a spring configuration file, Applicationcontext.xml contains the following scan configurations:When the container starts, all the annotated classes are instantiated in the package that is being scanned. However, if the scan configuration describe

Introduction to the first chapter 1. Here is a simple example of a duck example. Ducks will bark, they'll go, they'll swim (the same part). But some ducks can fly, some ducks look different and so on (become part), how to design it. By separating the invariant and variable parts, we draw our first design principle: Identify the changes that might be needed in the application, separate them, and not mix with the code that doesn't need to change. 2.
