Hello sir, do you know how to configure connection with druid database
How do you have so vast knowledge on so many technologies?
ma'em could you please help me in this regards ?
why you created the findById method sir! isn't it the default method of CrudRepository interface?
Please let me know this ans.
I have the same doubt that CrudRepository is an interface itself by why you have written body of FindById() as we know that we can get this method by CrudRepository itself.
Please ans
sir is this ths end of spring boot?
please did this with h2 memory database
java.lang.IllegalArgumentException: Entity must not be null show error please tell me sir how to solve this problem
Can any one explain why there is need of creating an abstract method findbyId specially in interface while others methods like save, deleteById is method is not declare in interface and my compiler is also shown error.
yes , it is because save() return type is Entity class . deleteById() return type is void . But findById() retrun type is Optional , so basically, we are overriding this method in interface by giving return type as Entity class .
if u give password to my sql then we write in app properties root as a password, if u dont give any password then dont write it it give u error.
Hey if your database value not inserted than you use the your Book repository interface @Repository annotation than problems is solve try this....👈🌟

@Durgesh sir ,
Please ap ye doubt clear kro ke apne CrudRepository m FindById () q use keya h apne ?
CrudRepository is an interface and it contains implementation of create,read/retrieve, update and delete then what is the use to just providing body of FindById () in CrudRepository interface.
Anyone please help me here
CrudRepository have FindById of type Optional but we need of type Book
Bro it’s a custom finder method please watch the previous video
I am getting an error under //get all books on line 29 saying Cannot cast from Iterable to List tried multiple times getting the same please help me to get through this issue
See I think it’s not possible because we can’t cast parent class obj into child class
Make sure you are not autowiring static variable it will fail.
sir next video kb aayge
why did we make find book by id in the repository and not in service??
We can make it , but we will have one problem as findById() returns Optional but we need entity class object .So method overriding happened in repository class .
U explained very well.....thank u......
But i hv question how do we handle with 2 db.
you have to add @Configuration and have two separate configuration for each dbs
Hello sir,
Yaha par photos ko kaise upload kare ?
Thank you sir
Sir database connection m problem ho rha h help kryega ?
What is mean by iterable
here you are not taking Optional when using findById() function
Agar update mai aise I'd update krege to database mai faltu entries badh jayegi
sir BookRepository ka object kaise ban skta hai bo to interface hai and BookRepository k upar koi annotation bhi nhi lagayi jabki BookService ko Autowired kiya hai BookController me to BookService k upar apne @component annotation use ki hai ..................Any one help me plz
use @Repository annotation on top of BookRepository class
I think it should work without annotation on Repository interface. Perhaps you have not made the dao package with the right path like com.api.book.dao.BookRepository. That was my problem and after the right path, I didn't get error like "Consider defining a bean of type 'dao.BookRepository' in your configuration."
@Service bhi use kro ge toh obj ban jaaye ga
sir can you upload this raw code
In application.properties this line needs to be added-->spring.jpa.hibernate.ddl-auto=create, else error is coming that table not found
hy i am sunny kosle i am getting some problem can you please fix my bugs
Why someone will buy your source code, while other youtube are giving free and you are asking student to pay for source code, Teacher.
sir source code kha mile ...kisi ko pta h toh plz btaae
sir update karne ke bad entry duplicate ban ja rahi hai ..aur kisika ho rah h aisa
Bhai vo islie ho rha kyunki jo book ki id hai vo auto generated hai toh agr hm kuch b update krte hai to tun book ki id ya toh vo wali id daalo jis book ko update kr rhe ho aur vo id data base me same ho...
Kyunki database me book ki id 1,2,3 bn rhi hai naa ki jo hum de rhe hai jaise 12, 24 ye nhi hai book id ...
Hope so tum smze hoge...
make sure ke URL me jo id hai aur body me jo id hai vo dono same ho
