如何使用Spring Boot搭建一个简单的篮球论坛系统，实际项目中你需要详细设计各个模块的功能，并确保代码质量和安全性。以下是一个简化版本的代码示例：

1. 添加依赖项

首先，在pom.xml文件中添加必要的依赖项：

<dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-jpa</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-security</artifactId></dependency><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId></dependency><!-- Thymeleaf for HTML templates --><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-thymeleaf</artifactId></dependency>
</dependencies>

2. 配置文件 `application.properties`

配置数据库连接和其他Spring Boot设置：

spring.datasource.url=jdbc:mysql://localhost:3306/basketball_forum?useUnicode=true&characterEncoding=utf8
spring.datasource.username=root
spring.datasource.password=yourpassword
spring.jpa.hibernate.ddl-auto=update
spring.jpa.show-sql=true

3. 主类 `BasketballForumApplication`

package com.example.basketballforum;import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;@SpringBootApplication
public class BasketballForumApplication {public static void main(String[] args) {SpringApplication.run(BasketballForumApplication.class, args);}}

4. 实体类 `User`

package com.example.basketballforum.model;import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;@Entity
public class User {@Id@GeneratedValue(strategy = GenerationType.IDENTITY)private Long id;private String username;private String password;// Getters and Setters
}

5. 接口 `UserService`

package com.example.basketballforum.service;import com.example.basketballforum.model.User;public interface UserService {User save(User user);User findByUsername(String username);
}

6. 控制器 `UserController`

package com.example.basketballforum.controller;import com.example.basketballforum.model.User;
import com.example.basketballforum.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;@RestController
@RequestMapping("/api/users")
public class UserController {private final UserService userService;@Autowiredpublic UserController(UserService userService) {this.userService = userService;}@PostMappingpublic User createUser(@RequestBody User user) {return userService.save(user);}
}
