Well, decorator mode comes out and we see how to call:
Copy Code code as follows:
Work squarepeg = new Squarepeg ();
Work decorator = new Decorator (squarepeg);
Decorator.insert ();
The decorator mode is complete.
If you are careful, you will notice that the call is similar to the one we read when reading the file:
Copy Code code as follows:
FileReader FR = new FileR
Java Factory mode (Factory Mode)The factory mode is the most common mode. The famous Jive forum has used the factory mode extensively. The factory mode can be seen everywhere in Java program systems. Why is the factory model so commonly used? Because the factory mode is equivalent to creating the new instance object, we often need to generate instance objects according to Class, for example, A a = new A () Factory mode is also used to create instance

Since we encapsulate database access, if we query a series of results returned by the database, for example, we get the username of all users from the database, and then display it on the JSP page.
There is a general question here: Is this JavaBean that returns resultset to JSP or collection?
I used to save some time and directly return the resultset, and then traverse a large number of resultsets on my JSP page. This actually obfuscated the data layer and the display layer. In the ejb cmp, the
