Question

我有购买的简单REST，我需要做的最后一件事是方法：报告2019 UAH —此命令应从http://fixer.io获取交叉货币汇率的列表（免费注册）计划），计算指定年份的总收入，将其转换并以指定货币显示，其中： 2019年–应计算总收入的年份 UAH-表示总收入的货币。我什至不知道如何处理它。甚至不知道保存货币和鞭子数据的最佳方法是什么。

 @Entity
@Table (name="purchase")
public class Purchase {

@Id
@Column(name = "id")
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;

 @Column(name = "name")
 private String name;

 @CreationTimestamp
 @Temporal(TemporalType.DATE)
 @Column(name="createat")
    private Date created;

 @Column(name="price")
 private BigDecimal price;


@Column(name="currency")
private String currency;}

 @Repository
public interface PurchaseRepository extends CrudRepository<Purchase, Long 
> {
List<Purchase> findById(Long id);
List<Purchase> findAllByOrderByCreatedAsc();
String deleteByCurrency(String currency);
long deleteByCreated(Date date);
}

@Service
public class PurchaseService {

@Autowired
private PurchaseRepository purchaseRepository;

public void addPurchase(Purchase purchase) {
    purchaseRepository.save(purchase);
}

public List<Purchase> getAllPurchase(){
    List<Purchase> purchase = new ArrayList<>();
    purchaseRepository.findAll().forEach(purchase::add);
    return purchase;
}
public List<Purchase> findAllSorted(){
    List<Purchase> persons = purchaseRepository.findById((long) 2);
    return persons;

}

@Transactional
public List<Purchase> findAllByOrderByCreatedAsc() {
    List<Purchase> persons = 
purchaseRepository.findAllByOrderByCreatedAsc();
    return persons;
}

@Transactional
public String deleteByCurrency(String currency) {
    return purchaseRepository.deleteByCurrency(currency);

};

@Transactional
public long deleteAllByDate(Date date){
    return purchaseRepository.deleteByCreated(date);
}
}

@RestController
public class PurchaseController {

@Autowired
private PurchaseService purchaseService;

@PostMapping("/purchase")
public void addPurchase (@RequestBody Purchase purchase) {
    purchaseService.addPurchase(purchase);}

    @RequestMapping("/purchase")
    public List<Purchase> getAllTopics(){
        return purchaseService.getAllPurchase();            
    }
    @RequestMapping("/purchasee")
    public List<Purchase> getAllbyName(){
        return purchaseService.findAllSorted();         
    }

    @RequestMapping("/purchases")
    public List<Purchase> getAllByDate(){
        return purchaseService.findAllByOrderByCreatedAsc();            
    }

    @RequestMapping(method=RequestMethod.DELETE, 
 value="/purchase/{created}")
    String deleteByDate(@PathVariable  String currency) {
        return purchaseService.deleteByCurrency(currency);

Method Report 2019 UAH —此命令应从http://fixer.io（注册免费计划）中获取交叉货币汇率列表，计算指定年份的总收入，将其转换为指定货币，其中：

2019年-应计算总收入的年份 UAH-表示总收入的货币

如何将货币兑换http://fixer.io添加到我的REST Api
