Spring uses annotation methods to inject multiple cases

At present Spring+netty development way so hot, want to register Netty spring components must be used in a number of ways, I can't help but want to spit groove obviously so common demand online related blog are less very, here give spring use annotation to inject many examples of way:

1. On classes that require multiple calls, add the@Scope("prototype")

2. In the injection, can not be used directly @Autowired , otherwise injected or singleton, need to use the factory, the simplest is to use

   @Autowiredprivate ObjectFactory<T> objectFactory;

   object is injected (T is the class you want to inject), and when you want to use the multi-instance object,

   T t = objectFactory.getObject();

   Method.
