Hey, in this video, 2

2

we're gonna learn how to use components 3

3

in the default bean id. 4

4

Well, so far we've already learned 5

5

how to specify the bean id in the component annotation. 6

6

So with our previous example, 7

7

we had tennis coach 8

8

and we have at component, 9

9

and we give that silly coach. 10

10

That's the bean id that we'll use 11

11

in our application. 12

12

So we can actually remove the actual bean id 13

13

and let Spring generate a default bean id. 14

14

The default bean id is basically the class name 15

15

and they simply make the first letter lowercase. 16

16

As an example, if we are a class of tennis coach 17

17

with a capital t, 18

18

then if we don't specify a bean id, 19

19

the default bean id will be tennis coach 20

20

with a lowercase t. 21

21

Okay, so let's kind of walk through this 22

22

with a code example. 23

23

So notice here I have tennis coach 24

24

and I have at component. 25

25

Note here, I didn't explicitly specify a bean id. 26

26

So again, we have the class name of tennis coach, 27

27

our default bean id will be tennis coach 28

28

with a lowercase t, 29

29

so they'll take the first letter of the class 30

30

and make it lowercase. 31

31

Now let's look at how we could use this in code now. 32

32

In our code to actually retrieve the bean 33

33

from the container, 34

34

I'd say context get bean, 35

35

and I give the default bean id, 36

36

which is tennis coach, 37

37

which starts with a lowercase t, 38

38

and that'll actually give me the bean 39

39

from the Spring container. 40

40

So again, notice here we're using the default bean id 41

41

since our class didn't explicitly specify a bean id. 42

42

And that's pretty much it. 43

43

So what we'll do in the next video 44

44

is we'll actually move into Eclipse 45

45

and we'll actually work through this example, 46

46

and we'll see how we can actually modify our code 47

47

to make use of the default bean id, 48

48

and then also retrieve it from the container. 49

49

So I'll see you in the next video.
