Better to take many small steps

“It is better to take many small steps in the right direction than to make a great leap forward only to stumble backward.”

3 ways to initialize and destroy Spring beans

There are 3 ways to initialize (and destroy) spring beans
1. Using init-method and destroy-method attributes
2. Implementing InitializingBean and DisposableBean interfaces
3. Using @PostConstruct and @PreDestroy Annotations (available only in Spring >=2.5)


1. Using init-method and destroy-method attributes
Certain bean methods can designated as initializing and destroying methods using the init-method and destroy-method attributes. Like so:

---

<bean
    id="studentService"

    class="initMethod.StudentServiceImpl"

    init-method="subscribe"

    destroy-method="unsubscribe"/>

---

2. Implementing InitializingBean and DisposableBean interfaces
The bean can implement these methods InitializingBean.afterPropertiesSet() and DisposableBean.destroy(). Like so:

---

public class StudentServiceImpl implements StudentService, InitializingBean, DisposableBean {

    @Override

    public boolean isExists(long studentId) {

        // A fake implementation

        if ( studentId % 2 == 0 )

        {

            return true;

        }

        else

        {

            return false;

        }

    }

    @Override

    public void afterPropertiesSet() throws Exception 

    {

        // subscribe logic goes here

    }

    @Override

    public void destroy() throws Exception 

    {

       // unsubscribe logic goes here

    }

}

---

3. Using @PostConstruct and @PreDestroy Annotations
Note that both of these are JSR-250 annotations (here is a nice introduction to JSR-250 support introduced in spring 2.5).

---

@PostConstruct
public void subscribe()
{
  // subscribe logic goes here
}


@PreDestroy
public void unsubscribe()
{
  // unsubscribe logic goes here
}

If the work is worthwhile, then whether we can complete it or not, it's worth making the attempt

If the work is worthwhile, then whether we can complete it or not, it's worth making the attempt. That's why courage is important.

Actions driven solely by anger are of no use at all

Actions driven solely by anger are of no use at all; realizing this can help strengthen your determination to resist it. - DalaiLama

One hand

"We are afraid of losing what we have, whether it's our life or our possessions and property. But this fear evaporates when we understand that our life stories and the history of the world were written by the same hand." Sometimes, the caravan (in the middle of a desert) met with another. One always had something that the other needed - as if everything were indeed written by one hand. - The Alchemist by Paulo Coelho

No matter how many detours and adjustments it made, the caravan moved towards the oasis.

"The desert was all sand in some stretches, and rocky in others. When the caravan was blocked by a boulder, it had to go around it; if there was a large rocky area, they had to make a major detour. If the sand was too fine for the animal's hooves, they sought a way where the sand was more substantial... If a guide were to fall ill or die, the camel driver would draw lots and appoint a new one. But all this happened for one basic reason: no matter how many detours and adjustments it made, the caravan moved towards the same compass point. Once obstacles were overcome, it returned to its course, sighting on a star that indicated the location of the oasis." - The Alchemist by Paulo Coelho

Don’t ask yourself what the world needs, ask yourself what makes you come alive

“Don’t ask yourself what the world needs, ask yourself what makes you come alive. And then go and do that. Because what the world needs is people who are alive.” - Howard Thurman through Think Simple Now

Nice article on Spring 2.5 features

Here is a nice article on Spring 2.5 features.

I am a parent and do not have the luxury of principles.

Father (who doesn't like his state going to war): I am a parent and do not have the luxury of principles.
...
Son (who is enlisting in the army): Father, I thought you were a man of principles.

Father: When you have a family of your own perhaps you will understand.

Son: When I have a family of my own I won't hide behind them.

- "The Patriot"

when each day is the same as the next

"...when each day is the same as the next, it's because people fail to
recognize the good things that happen in their lives every day that the
sun rises."

There isn’t a way things should be. There’s just what happens, and what we do.

This is your life. Learn to enjoy what you’ve got.

“This is your life. Learn to enjoy what you’ve got.”

- Mr. Destiny through Julie911

If we cannot love ourselves, we cannot fully open to our ability to love others or our potential to create.

“There are two basic motivating forces: fear and love. When we are afraid, we pull back from life. When we are in love, we open to all that life has to offer with passion, excitement, and acceptance. We need to learn to love ourselves first, in all our glory and our imperfections. If we cannot love ourselves, we cannot fully open to our ability to love others or our potential to create. Evolution and all hopes for a better world rest in the fearlessness and open-hearted vision of people who embrace life.”

- John Lennon through Juliee911

Everybody is a genius

“Everybody is a genius. But if you judge a fish by its ability to climb a tree, it will live its whole life believing that it is stupid.”

Reliable and genuine discipline

Reliable and genuine discipline comes not from repression, but from an
understanding of all the whys and wherefores of our actions.

- Dalai Lama

The day we fret about the future is the day we leave our childhood behind.

“When we are children we seldom think of the future. This innocence leaves us free to enjoy ourselves as few adults can. The day we fret about the future is the day we leave our childhood behind.”
