具有相似模式的java Spring多数据源

Question

我在PostgreSQL上有4个模式类似的数据库

我现在的代码是这样的

资源

spring.datasource.url=jdbc:postgresql://localhost:5432/postgres
spring.datasource.username=postgres
spring.datasource.password=postgres

DAO

public interface AccountRepository extends JpaRepository<Account, Long>{}

配置

@Configuration
public class AccountServiceConfiguration {
    @Autowired
    private AccountRepository accountRepository;

    @Bean
    public AccountService accountService() {
        return new AccountService(accountRepository);
    }
}

控制器

@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);
    }
}

服务

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);
    }
}

我想这样改变

资源

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

控制器

...
public Page<Account> getAccounts(Integer page, Integer size, string env) {
    return accountService.getAll(page, size, env);
}
...

服务

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
    }
}

如何加载4个数据源（可能在地图上）并按环境搜索！ 如果我发送env=db1，我想在db1上运行我的请求

如果您有其他解决方案，我接受它，但必须使用一个存储库和一个实体来搜索所有数据库

谢谢：）
