协同伙伴充值平台 J影音a 示例源码 本示例源码实现了一个简单的业务伙伴充值平台，允许用户通过合作伙伴进行在线充值。 数据库表结构 ``` CREATE TABLE users ( id INT NOT NULL AUTO_INCREMENT, username VARCHAR(255) NOT NULL, password VARCHAR(255) NOT NULL, PRIMARY KEY (id) ); CREATE TABLE games ( id INT NOT NULL AUTO_INCREMENT, name VARCHAR(255) NOT NULL, PRIMARY KEY (id) ); CREATE TABLE orders ( id INT NOT NULL AUTO_INCREMENT, user_id INT NOT NULL, game_id INT NOT NULL, amount INT NOT NULL, created_at TIMESTAMP NOT NULL, PRIMARY KEY (id), FOREIGN KEY (user_id) REFERENCES users (id), FOREIGN KEY (game_id) REFERENCES games (id) ); ``` 实体类 ```j影音a import j影音ax.persistence.; @Entity @Table(name = "users") public class User { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) private Integer id; private String username; private String password; // getters and setters } @Entity @Table(name = "games") public class Game { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) private Integer id; private String name; // getters and setters } @Entity @Table(name = "orders") public class Order { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) private Integer id; private Integer userId; private Integer gameId; private Integer amount; private Date createdAt; // getters and setters } ``` 服务层 ```j影音a import j视频a.util.List; public interface UserService { List findAll(); User findByUsername(String username); void createOrder(Order order); } ``` ```j多媒体a import j视频a.util.List; public interface GameService { List findAll(); Game findById(Integer id); } ``` ```j影音a import j视频a.util.List; public interface OrderService { List findAll(); void createOrder(Order order); } ``` 控制器 ```j影音a import org.springframework.web.bind.annotation.; @RestController @RequestMapping("/api") public class UserController { private final UserService userService; public UserController(UserService userService) { this.userService = userService; } @GetMapping("/users") public List getAllUsers() { return userService.findAll(); } @GetMapping("/users/{username}") public User getUserByUsername(@PathVariable String username) { return userService.findByUsername(username); } @PostMapping("/users") public User createUser(@RequestBody User user) { return userService.create(user); } } ``` ```j多媒体a import org.springframework.web.bind.annotation.; @RestController @RequestMapping("/api") public class GameController { private final GameService gameService; public GameController(GameService gameService) { this.gameService = gameService; } @GetMapping("/games") public List getAllGames() { return gameService.findAll(); } @GetMapping("/games/{id}") public Game getGameById(@PathVariable Integer id) { return gameService.findById(id); } } ``` ```j视频a import org.springframework.web.bind.annotation.; @RestController @RequestMapping("/api") public class OrderController { private final OrderService orderService; public OrderController(OrderService orderService) { this.orderService = orderService; } @GetMapping("/orders") public List getAllOrders() { return orderService.findAll(); } @PostMapping("/orders") public Order createOrder(@RequestBody Order order) { return orderService.create(order); } } ``` 运行示例 导入本示例源码到您喜欢的 J多媒体a IDE 中。 创建一个数据库并调整数据库连接配置。 运行该应用程序。 4. 打开浏览器并访问 `http://localhost:8080/api/users` 以获取所有用户的列表。 注意： 实际的充值逻辑可能涉及与第三方支付网关的集成。 您还需要处理安全和验证以确保平台安全。
