However, the dynamic property is the interface default support. Ducktype can be easily injected.

Full class name (FQCN) is an identifier

to compensate for the type safety problem in the pure string request pattern, the full class name ( FQCN) The request pattern was born. The idea is that dependencies are not passed through the identifier of the string, but by the full class name of the requested dependency, when the object is requested by the container. This will prompt the "class does not exist" at compile time if the developer mistakenly writes the full class name identifier incorrectly. And, if you use IDE development tools such as Eclipse, it's easy to define the full class name identifier of the dependency into your code with the functionality of the automatic full code it provides

Mixed Request Mode

The previous section talked about The FQCN (full class name) request pattern leads to a poor softness of the dependency definition, so that the pattern of string and full-class name blending has emerged. For example, just the API in spring to declare the injection point example can be changed to use the following API:

//Spring string + API for full class name injection beanfactory Injector = new  filesystemapplicationcontext (" Depositconfiguration.xml ") this .bank = (Bank) Injector.getbean ("bank", Bank. class ); //request named "Bank" and the class is Bank dependent  

you can use the in-class builder.
