What do you understand by auto wiring and name the different modes of it?

Accepted Answer

The Spring container is able to autowire relationships between the collaborating beans. That is, it is possible to let
Spring resolve collaborators for your bean automatically by inspecting the contents of the BeanFactory.

Different modes of bean auto-wiring are:

1) no : This is default setting which means no autowiring. Explicit bean reference should be used for wiring.

2) byName : It injects the object dependency according to name of the bean. It matches and wires its properties with
the beans defined by the same names in the XML file.

3) byType : It injects the object dependency according to type. It matches and wires a property if its type matches with
exactly one of the beans name in XML file.

4) constructor : It injects the dependency by calling the constructor of the class. It has a large number of parameters.

5) autodetect : First the container tries to wire using autowire by constructor, if it can’t then it tries to autowire by
byType.
