假设您的实体类为Score，您可以使用Spring Data JPA来完成对scores表的操作。首先，在Score实体类中添加一个名为admins的属性，并生成对应的getter和setter方法，然后在UserController中注入ScoreRepository，如下所示：

@RestController
@RequestMapping("/api")
public class UserController {

    @Autowired
    private ScoreRepository scoreRepository;

    @PostMapping("/scores")
    public Score addScore(@RequestBody Score score) {
        score.setAdmins(0.0f); // 设置admins属性为0
        return scoreRepository.save(score);
    }
}

在上面的代码中，我们使用了@PostMapping注解来处理POST请求，并使用@RequestBody注解将请求体映射为Score对象。然后，我们设置admins属性的默认值为0，并将Score对象保存到数据库中。

当您发送一个POST请求到/api/scores路径时，该方法将被调用，Score对象将从请求体中解析出来，并设置默认值后保存到数据库中。

已知scores数据表：-- aokace.scores definition CREATE TABLE `scores` ( `scoresid` int NOT NULL AUTO_INCREMENT, `scorestime` date DEFAULT NULL, `departname` varchar(100) NOT NULL, `positname` varchar(100) NOT NULL, `gradesname` varchar(100) NOT NULL, `emploname` varchar(100) NOT NULL, `scoresa` float NOT NULL, `scoresb` float NOT NULL, `scoresc` float NOT NULL, `scoresd` float NOT NULL, `overviw` text CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci NOT NULL, `manager` float NOT NULL, `admins` float DEFAULT NULL, `average` float DEFAULT NULL, PRIMARY KEY (`scoresid`), KEY `scores_FK` (`departname`), KEY `scores_FK_1` (`positname`), KEY `scores_FK_2` (`gradesname`), KEY `scores_FK_3` (`emploname`), CONSTRAINT `scores_FK` FOREIGN KEY (`departname`) REFERENCES `department` (`departname`), CONSTRAINT `scores_FK_1` FOREIGN KEY (`positname`) REFERENCES `position` (`positname`), CONSTRAINT `scores_FK_2` FOREIGN KEY (`gradesname`) REFERENCES `grades` (`gradesname`), CONSTRAINT `scores_FK_3` FOREIGN KEY (`emploname`) REFERENCES `employe` (`emploname`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci; 如何在ScoresController（ package com.aokace.controller; import com.aokace.service.ScoresService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; /** * <p> * 前端控制器 * </p> * * @author aokace * @since 2023-06-12 */ @RestController @RequestMapping("/scores") public class ScoresController { @Autowired private ScoresService scoresService; } ）中实现在scores表的数据中修改admin数据 保存但不改变 数据的id

您可以在ScoresController中添加一个@RequestMapping映射，来处理修改admin数据的请求。然后在该方法中，可以调用ScoresService中的方法来获取要修改的数据，并更新其中的admin字段。最后，调用ScoresService中的另一个方法来保存修改后的数据，但不改变数据的id。

具体实现如下：

@RestController
@RequestMapping("/scores")
public class ScoresController {

    @Autowired
    private ScoresService scoresService;

    @RequestMapping("/updateAdmin")
    public void updateAdmin(@RequestParam("id") int id, @RequestParam("admin") float admin) {
        // 调用ScoresService中的方法获取要修改的数据
        Scores scores = scoresService.getById(id);
        // 更新admin字段
        scores.setAdmins(admin);
        // 调用ScoresService中的方法保存修改后的数据，不改变数据的id
        scoresService.updateWithoutChangingId(scores);
    }
}

需要注意的是，这里使用了@RequestParam注解来获取请求参数，其中id是要修改的数据的id，admin是要更新的admin字段的值。ScoresService中的方法需要自行实现。

学生成绩mvc mysql_大作业练习:用Asp.net Mvc4做一个:学生考试成绩管理系统-简易版...

好的，下面是一个简单的学生考试成绩管理系统的实现：

1. 创建数据库

首先在 MySQL 中创建一个名为 `student_score` 的数据库，然后创建以下两个表：

- `students` 表，用于存储学生信息，包括学生 ID、姓名和班级。

CREATE TABLE `students` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(50) DEFAULT NULL,
  `class` varchar(50) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

- `scores` 表，用于存储学生考试成绩，包括学生 ID、科目和成绩。

CREATE TABLE `scores` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `student_id` int(11) DEFAULT NULL,
  `subject` varchar(50) DEFAULT NULL,
  `score` int(11) DEFAULT NULL,
  PRIMARY KEY (`id`),
  KEY `FK_scores_students` (`student_id`),
  CONSTRAINT `FK_scores_students` FOREIGN KEY (`student_id`) REFERENCES `students` (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

2. 创建 ASP.NET MVC4 项目

在 Visual Studio 中创建一个 ASP.NET MVC4 项目，选择 Empty 模板。

3. 添加模型

在项目中添加两个模型类 `Student` 和 `Score`，代码如下：

public class Student
{
    public int Id { get; set; }
    public string Name { get; set; }
    public string Class { get; set; }
}

public class Score
{
    public int Id { get; set; }
    public int StudentId { get; set; }
    public string Subject { get; set; }
    public int Score { get; set; }
}

4. 添加控制器

在 Controllers 文件夹中添加一个名为 `HomeController` 的控制器，其中包含以下几个动作方法：

- `Index` 方法，用于显示学生列表和成绩列表。

public ActionResult Index()
{
    var students = db.Students.ToList();
    var scores = db.Scores.ToList();
    ViewBag.Students = students;
    ViewBag.Scores = scores;
    return View();
}

- `AddStudent` 方法，用于添加新的学生信息。

[HttpPost]
public ActionResult AddStudent(Student student)
{
    db.Students.Add(student);
    db.SaveChanges();
    return RedirectToAction("Index");
}

- `AddScore` 方法，用于添加新的成绩信息。

[HttpPost]
public ActionResult AddScore(Score score)
{
    db.Scores.Add(score);
    db.SaveChanges();
    return RedirectToAction("Index");
}

5. 添加视图

在 Views 文件夹中添加一个名为 `Index.cshtml` 的视图，用于显示学生列表和成绩列表。

@model IEnumerable<StudentScore.Models.Student>

@{
    ViewBag.Title = "学生考试成绩管理系统";
}

<h2>学生列表</h2>
<table class="table">
    <thead>
        <tr>
            <th>ID</th>
            <th>姓名</th>
            <th>班级</th>
        </tr>
    </thead>
    <tbody>
        @foreach (var student in ViewBag.Students)
        {
            <tr>
                <td>@student.Id</td>
                <td>@student.Name</td>
                <td>@student.Class</td>
            </tr>
        }
    </tbody>
</table>

<h2>成绩列表</h2>
<table class="table">
    <thead>
        <tr>
            <th>ID</th>

            <th>成绩</th>
        </tr>
    </thead>
    <tbody>
        @foreach (var score in ViewBag.Scores)
        {
            <tr>
                <td>@score.Id</td>
                <td>@score.StudentId</td>
                <td>@score.Subject</td>
