Implementation of Spring IOC + AOP

Spring thought very well and minimized intrusive programming. It is now understood that spring provides features, DI,IOC, database operations, AOP,MVC. Wrote some small demo for DI,AOP.

PS:AOP is really good.

Code reference: "Spring Combat" third edition

Environment:

Win7 64

IDE Eclipse

JDK 1.8

Spring 4.1.7

------------------------------------------------I'm a code splitting line---------------------------------------------------------

Ideas:

A performer and audience, performers and viewers are injected through DI (XML and annotation injections), and the audience moves through AOP (the database writes some configuration files) before the performer's performance.

Performer Performer.java

1  PackageCom.gxf.beans;2 3 /**4 * Performers5  * @authorGXF6  *7  */8  Public classPerformer {9     Ten     /** One * performers ' performance behavior A      */ -      Public voidperform () { -SYSTEM.OUT.PRINTLN ("Performers begin to perform"); the     } -}

Audience Audience.java

1 /**2 * Audience3  * @authorGXF4  *5  */6  Public classAudience {7     8     /**9 * Before the show, the audience began to find seatsTen      */ One      Public voidtakeseats () { ASystem.out.println ("Audience starts looking for seats"); -     } -      the     /** - * Audience shutdown before the show -      */ -      Public voidTurnoffcellphone () { +System.out.println ("Audience will hand machine"); -     } +      A     /** at * The show's over, the audience starts clapping -      */ -      Public voidapplaud () { -System.out.println ("Audience starts clapping"); -     } -      in     /** - * The performance failed, the audience demanded a refund to      */ +      Public voidDemandrefund () { -SYSTEM.OUT.PRINTLN ("Hush! Refund! "); the     } *}

There are some test Di and database code not completed, database I think it is better to use the ORM Framework, although spring provides some template methods to manage the database, but it is not easy to use the ORM framework.
