Column(unique true, nullable false) private String username; Column(nullable false) private String password; OneToMany(mappedBy user, cascade CascadeType.ALL) private ListCreditCard creditCards; // Getters and Setters } Repository public interface UserRepository extends JpaRepositoryUser, Long { User findByUsername(String username); } Service public class UserService { Autowired private UserRepository userRepository; Autowired private PasswordEncoder passwordEncoder; public User registerUser(User user) { user.setPassword(passwordEncoder.encode(user.getPassword())); return userRepository.save(user); } }信用卡管理模块Entity Table(name credit_cards) public class CreditCard { Id Column(unique true, nullable false) private String cardNumber; ManyToOne JoinColumn(name user_id, nullable false) private User user; private BigDecimal creditLimit; private BigDecimal availableBalance; private LocalDate expiryDate; private String cvv; // Getters and Setters } Repository public interface CreditCardRepository extends JpaRepositoryCreditCard, String { ListCreditCard findByUser(User user); } Service public class CreditCardService { Autowired private CreditCardRepository creditCardRepository; public CreditCard createCard(CreditCard card) { // 生成随机卡号逻辑 String cardNumber generateCardNumber(); card.setCardNumber(cardNumber); return creditCardRepository.save(card); } private String generateCardNumber() { // 实现卡号生成逻辑 } }交易处理模块Entity Table(name transactions) public class Transaction { Id GeneratedValue(strategy GenerationType.IDENTITY) private Long id; ManyToOne JoinColumn(name card_number, nullable false) private CreditCard creditCard; private BigDecimal amount; private String merchant; private LocalDateTime transactionDate; private TransactionType type; // PURCHASE, PAYMENT, etc. // Getters and Setters } public enum TransactionType { PURCHASE, PAYMENT, CASH_ADVANCE, FEE } Service public class TransactionService { Autowired private CreditCardRepository creditCardRepository; Autowired private TransactionRepository transactionRepository; Transactional public Transaction processTransaction(TransactionDTO dto) { CreditCard card creditCardRepository.findById(dto.getCardNumber()) .orElseThrow(() - new CardNotFoundException()); if (dto.getType() TransactionType.PURCHASE) { if (card.getAvailableBalance().compareTo(dto.getAmount()) 0) { throw new InsufficientFundsException(); } card.setAvailableBalance(card.getAvailableBalance().subtract(dto.getAmount())); } else if (dto.getType() TransactionType.PAYMENT) { card.setAvailableBalance(card.getAvailableBalance().add(dto.getAmount())); } creditCardRepository.save(card); Transaction transaction new Transaction(); // 设置transaction属性 return transactionRepository.save(transaction); } }账单生成模块Service public class BillingService { Autowired private TransactionRepository transactionRepository; public Bill generateMonthlyBill(String cardNumber, YearMonth yearMonth) { LocalDate startDate yearMonth.atDay(1); LocalDate endDate yearMonth.atEndOfMonth(); ListTransaction transactions transactionRepository .findByCreditCardCardNumberAndTransactionDateBetween( cardNumber, startDate.atStartOfDay(), endDate.atTime(23, 59, 59)); Bill bill new Bill(); // 计算总消费、最低还款额等 return bill; } }风控模块Service public class RiskControlService { Autowired private TransactionRepository transactionRepository; public boolean isTransactionSuspicious(TransactionDTO dto) { // 检查异常交易模式 ListTransaction recentTransactions transactionRepository .findTop10ByCreditCardCardNumberOrderByTransactionDateDesc(dto.getCardNumber()); // 实现风控逻辑 return false; } }REST API控制器RestController RequestMapping(/api/credit-cards) public class CreditCardController { Autowired private CreditCardService creditCardService; PostMapping public ResponseEntityCreditCard createCard(RequestBody CreditCardDTO dto) { CreditCard card creditCardService.createCard(convertToEntity(dto)); return ResponseEntity.ok(card); } GetMapping(/{cardNumber}/transactions) public ResponseEntityListTransaction getTransactions( PathVariable String cardNumber, RequestParam(required false) YearMonth month) { // 实现获取交易记录逻辑 } }安全配置Configuration EnableWebSecurity public class SecurityConfig extends WebSecurityConfigurerAdapter { Override protected void configure(HttpSecurity http) throws Exception { http.csrf().disable() .authorizeRequests() .antMatchers(/api/auth/**).permitAll() .anyRequest().authenticated() .and() .addFilter(new JWTAuthenticationFilter(authenticationManager())) .addFilter(new JWTAuthorizationFilter(authenticationManager())) .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS); } }数据库配置Configuration EnableTransactionManagement EnableJpaRepositories(basePackages com.example.creditcard.repository) public class DatabaseConfig { Bean public DataSource dataSource() { // 配置数据源 } Bean public JpaTransactionManager transactionManager(EntityManagerFactory emf) { return new JpaTransactionManager(emf); } }以上代码展示了信用卡管理系统的核心模块实现实际开发中需要根据具体需求进行调整和完善。系统还应该包括异常处理、日志记录、测试等辅助功能。
