when spring bean is loaded and if i have a constructor and setters which one will be called first?

Question

This is a basic question - when spring bean is loaded and if i have a constructor and setters which one will be called first?

Thanks

Answer 1

The constructor must be called before any setter methods are called. Use the init-method to tell Spring to invoke some logic after the setters are called:

<bean class="my.CoolClass" init-method="startup">
    <constructor-arg value="Foo" />
    <property name="bar" value="baz" />
</bean>

Answer 2

Doesn't the constructor have to be called first? The setters are instance methods so that can't called until the object is instantiated.
