Spring injection using setter and constructor, use inti and destroy method in bean

Whenever a single bean object is created in a this config file, all of the beans declared in this file will be created.

Using setter-------------------

 <bean class="" name="" init-method="" destroy-method="">

    <properties name="">

        <value>

         //give value here

        </value>

    </properties>

</bean>

or

<bean class="" name="" init-method="" destroy-method="">

    <properties name="" value="">

    </properties>

</bean>

or

<bean class="" name="" p:nameOfVariable="" init-method="" destroy-method=""/>          //this is using p schema

Using constructor 

Using setter-------------------

 <bean class="" name="" init-method="" destroy-method="">

    <constructor-args name="">

        <value>

         //give value here

        </value>

    </constructor-args>

</bean>

or

<bean class="" name="" init-method="" destroy-method="">

    <constructor-args name="" value="">

    </constructor-args>

</bean>

or

<bean class="" name="" c:nameOfVariable="" init-method="" destroy-method=""/>        //this is using c schema

Using annotation

@PostConstruct

@PreDestroy

This two annotation is used before init and destroy method

It is enabled by using both way in xml file.

<context:annotation-config/>

or

<bean class="org.springframework.context.annotation.CommonAnnotationBeanPostProcessor/>
