How to use Initialization callbacks in Spring Framework

[JavaBean]

org.springframework.beans.factory.InitializingBean interface exactly specifies following one method:

Code:

     void afterPropertiesSet() throws Exception;

But this is not a good approach as code will be coupled with Spring. So Spring have an feature .In XML-based configuration metadata, this can be done using the 'init-method' attribute.

Code:

<bean id="sampleInitBean" class="sample.SampleBean" init-method="init"/>

public class SampleBean {
public void init() {
// initialization code
}
}

This code is same as

Code:

<bean id="sampleInitBean" class="sample.AnotherSampleBean"/>
public class SampleExampleBean implements InitializingBean {
public void afterPropertiesSet() {
//  initialization coding
}
}
