Difference between spring setter and interface injection?
- by Satish Pandey
I know how constructor and setter injection works in spring.
Normally I use interfaces instead of classes to inject beans using setter and I consider it as interface injection, but in case of constructor we also use interfaces (I am confused). In following example I use JobProcessor interface instead of JobProcessorImpl class.
public class JobScheduler {
// JobProcessor interface
private JobProcessor jobProcessor;
// Dependecy injection
public void setJobProcessor(JobProcessor jobProcessor){
this.jobProcessor = jobProcessor;
}
}
I tried to find a solution by googling but there are different opinions by writers. Even some people says that spring doesn't support interface injection in their blogs/statements.
Can someone help me by example?
