Could not instantiate bean class: Specified class is an interface

Question

I know there are threads similar to this issue. Below is my class and I am configuring it in spring.xml file. Actually HumanResourceService is an interface having only one m

Answer 1

You can't, Spring needs something it can make an instance from, the interface isn't enough.

In your spring.xml, the value of the class attribute for your bean with id="humanResourceService" should be the name of your implementation class, not the interface. Spring needs you to tell it what implementation class you want it to use for this.
