Java – spring autowire using the types defined in the comments and properties file?

My goal is a framework in which specific types of beans can be easily changed through property files I also prefer annotations to XML Ideally, I would use a combination of @ resource and spiel, as follows:

@Resource(type="#{myProperties['enabled.subtype']}")
SomeInterface foo;

I've loaded myproperties using properties for actor bean or < util: Properties > From a file containing:

enabled.type = com.mycompany.someClassA; // which implements SomeInterface

This does not work because parameters of type must be literal, i.e. spel. Is not allowed What are the best practices here?

Update: please refer to the answers below

Solution

This is the use case of spring Java configuration

http://static.springsource.org/spring/docs/3.0.x/spring-framework-reference/html/beans.html#beans -java

Or you can build a factory

Use: org springframework. beans. factory. factorybean< SomeInterface>

The name of the bean that implements the factorybean will be treated as "someinterface", even if it is not
