写基于ssm框架出道选秀管理系统实现选手上传视频，查看选手个人页面，提交退赛申请表代码

很抱歉，我作为一个 AI 语言模型，并不能直接为您提供完整的代码。但是，我可以为您提供一些代码片段和思路，帮助您实现选手上传视频、查看选手个人页面和提交退赛申请表的功能。

1. 选手上传视频

首先，在选手实体类中添加一个视频链接属性：

public class Player {
    private Integer id;
    private String name;
    private String gender;
    private Integer age;
    private String contact;
    private String videoUrl;
    // getter 和 setter 方法
}

然后，在选手管理模块中添加一个上传视频的接口：

@Controller
@RequestMapping("/player")
public class PlayerController {
    @Autowired
    private PlayerService playerService;

    @PostMapping("/upload")
    @ResponseBody
    public String uploadVideo(@RequestParam("file") MultipartFile file, @RequestParam("playerId") Integer playerId) {
        if (file.isEmpty()) {
            return "文件为空";
        }
        try {
            byte[] bytes = file.getBytes();
            String fileName = file.getOriginalFilename();
            String videoUrl = "http://localhost:8080/video/" + fileName;
            // 将视频链接更新到选手信息中
            playerService.updatePlayerVideo(playerId, videoUrl);
            // 将视频保存到本地磁盘
            Path path = Paths.get("src/main/resources/static/video/" + fileName);
            Files.write(path, bytes);
            return "上传成功";
        } catch (IOException e) {
            e.printStackTrace();
            return "上传失败";
        }
    }
}

2. 查看选手个人页面

在选手管理模块中添加一个查看选手个人页面的接口：

@Controller
@RequestMapping("/player")
public class PlayerController {
    @Autowired
    private PlayerService playerService;

    @GetMapping("/{id}")
    public String getPlayerPage(@PathVariable("id") Integer id, Model model) {
        Player player = playerService.getPlayerById(id);
        model.addAttribute("player", player);
        return "player";
    }
}

在前端页面中展示选手的基本信息和上传的视频链接：

<div>
    <p>姓名：${player.name}</p>
    <p>性别：${player.gender}</p>
    <p>年龄：${player.age}</p>
    <p>联系方式：${player.contact}</p>
    <p>视频链接：<a href="${player.videoUrl}">${player.videoUrl}</a></p>
</div>

3. 提交退赛申请表

在选手实体类中添加一个退赛状态属性：

public class Player {
    private Integer id;
    private String name;
    private String gender;
    private Integer age;
    private String contact;
    private String videoUrl;
    private Integer quitStatus;
    // getter 和 setter 方法
}

在选手管理模块中添加一个提交退赛申请表的接口：

@Controller
@RequestMapping("/player")
public class PlayerController {
    @Autowired
    private PlayerService playerService;

    @PostMapping("/quit")
    @ResponseBody
    public String quitPlayer(@RequestParam("playerId") Integer playerId) {
        playerService.updatePlayerQuitStatus(playerId, 1);
        return "提交成功";
    }
}

在管理员管理模块中添加一个审核退赛申请的接口：

@Controller
@RequestMapping("/admin")
public class AdminController {
    @Autowired
    private PlayerService playerService;

    @GetMapping("/quit")
    public String getQuitPlayerList(Model model) {
        List<Player> players = playerService.getQuitPlayerList();
        model.addAttribute("players", players);
        return "quitList";
    }

    @PostMapping("/quit")
    @ResponseBody
    public String approveQuitPlayer(@RequestParam("playerId") Integer playerId) {
        playerService.updatePlayerQuitStatus(playerId, 2);
        return "审核成功";
    }
}

以上仅仅是一个大致的思路和代码片段，具体的实现过程还需要深入研究和实践。
