I have 4 databases with similar schema on PostgreSQL
My current code is like this
ressources
spring.datasource.url=jdbc:postgresql://localhost:5432/postgres
spring.datasource.username=postgres
spring.datasource.password=postgres
DAO
public interface AccountRepository extends JpaRepository<Account, Long>{}
Configuration
@Configuration
public class AccountServiceConfiguration {
@Autowired
private AccountRepository accountRepository;
@Bean
public AccountService accountService() {
return new AccountService(accountRepository);
}
}
Controller
@RestController
@RequestMapping("/accounts")
public class AccountController {
@Autowired
private AccountService accountService;
@RequestMapping(name = "/", method = RequestMethod.GET)
public Page<Account> getAccounts(Integer page, Integer size) {
return accountService.getAll(page, size);
}
}
Service
public class AccounttService {
public AccounttService(AccountRepository accountRepository) {
this.accountRepository = accountRepository;
}
public Page<Account> getAll(Integer page, Integer size) {
PageRequest pageRequest = new PageRequest(page, size);
return accountRepository.findAll(pageRequest);
}
}
I want to change like this
ressources
spring.db1.url=jdbc:postgresql://db1:5432/postgres
spring.db1.username=postgres1
spring.db1.password=postgres1
spring.db2.url=jdbc:postgresql://db2:5432/postgres
spring.db2.username=postgres2
spring.db2.password=postgres2
spring.db3.url=jdbc:postgresql://db3:5432/postgres
spring.db3.username=postgres3
spring.db3.password=postgres3
spring.db4.url=jdbc:postgresql://db4:5432/postgres
spring.db4.username=postgres4
spring.db4.password=postgres4
Controller
...
public Page<Account> getAccounts(Integer page, Integer size, string env) {
return accountService.getAll(page, size, env);
}
...
Service
public class AccounttService {
public AccounttService(Map<AccountRepository> mapAccountRepository) {
this.mapAccountRepository = mapAccountRepository;
}
public Page<Account> getAll(Integer page, Integer size, String env) {
PageRequest pageRequest = new PageRequest(page, size);
// search in specific env
}
}
How to load 4 data sources (may be on map) and search by environnement ! If i send env=db1 i want to run my request on db1
If you have other solution, i take it, but must use one repository and one entity to search in all databases.
Thank you :)
