Spring bean destroy-method , singleton and prototype scopes

Question

I am new to the spring framework, started with some tutorials to learn it.

I have following files,

# MainProgram.java

package test.spring;
im         


        

Answer 1

xmlDestroy() method is called with singleton scope bean but not with prototype because

Spring does not manage the complete lifecycle of a prototype bean: the container instantiates, configures, decorates and otherwise assembles a prototype object, hands it to the client and then has no further knowledge of that prototype instance. For releasing resources try to implement a custom bean post processor.

Unlike singleton beans where the spring container manages the complete life-cycle

You can have a look at this basic tutorial for differences between different contexts
