RestFulClient CRUDRepository Implementation - spring-boot

Question

I am using SpringBoot to write web service client. How to use CRUDRepository inside the client? I have to save the data from the webservice to a database table? How do I get the handle to BookRepository inside my client?
public interface BookRepository extends CrudRepository<BooksStage, Long> {}
RestTemplate restTemplate = new RestTemplate();
ResponseEntity<Books[]> responseEntity = restTemplate.getForEntity("http://localhost:8080/booksList", Books[].class);
Books[] books=responseEntity.getBody();
if(books!=null){
log.info("booksreceived -"+books.length);
for (Books c : books){
//Insert into database
}
}

Answer 1

1) Interface BookRepository shall be annotated with #Repository. You should autowire interface BookRepository in your Web Service Client class.
2) The RestTemplate shall be inside a Web Service Client class annotated with #Service
3) Since your entity name is BooksStage, you should only save entity of type BooksStage (and not Books).
#Repository
public interface BookRepository extends CrudRepository<BooksStage, Long> {
}
#Service
public class MyWebServiceClient{
#Autowired
private BookRepository bookRepo;
public boolean updateSomeBook() {
RestTemplate restTemplate = new RestTemplate();
ResponseEntity<BooksStage[]> responseEntity =
restTemplate.getForEntity ("http://localhost:8080/booksList", Books[].class);
BooksStage[] books=responseEntity.getBody();
if(books!=null){
log.info("booksreceived -"+books.length);
for (BooksStage c : books){
bookRepo.save(c);
}
return true;
}
}
#Entity
#Table(name = "books_stage")
public class BooksStage {
#Id
#Column(name = "ID")
private long id;
//other related fields
}
