代理充值平台 Java 示例源码

本示例源码实现了一个简单的代理充值平台，允许用户通过代理进行在线充值。

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

```java

import javax.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

```java

import java.util.List;

public interface UserService {

List findAll();

User findByUsername(String username);

void createOrder(Order order);

}

```

```java

import java.util.List;

public interface GameService {

List findAll();

Game findById(Integer id);

}

```

```java

import java.util.List;

public interface OrderService {

List findAll();

void createOrder(Order order);

}

```

控制器

```java

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);

}

}

```

```java

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);

}

}

```

```java

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 Java 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。
