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;

    @Autowired
    public UserController(UserService userService) {
        this.userService = userService;
    }

    @PostMapping
    public User createUser(@RequestBody User user) {
        return userService.save(user);
    }
}
