校园管理系统的前后端实现代码

校园管理系统的前后端实现代码比较复杂，需要涉及多种技术和语言。以下是一个基于Java语言和MySQL数据库的简单校园管理系统的前后端实现代码示例，仅供参考：

后端代码（Java + Spring Boot + MyBatis）：

1. 学生实体类

public class Student {
    private Integer id;
    private String name;
    private String gender;
    private Integer age;
    private String major;
    // 省略getters和setters
}

2. 学生DAO接口

public interface StudentMapper {
    List<Student> findAll();
    Student findById(Integer id);
    void add(Student student);
    void update(Student student);
    void delete(Integer id);
}

3. 学生DAO实现类

@Repository
public class StudentMapperImpl implements StudentMapper {
    @Autowired
    private JdbcTemplate jdbcTemplate;

    @Override
    public List<Student> findAll() {
        List<Student> students = jdbcTemplate.query("SELECT * FROM student", new BeanPropertyRowMapper<>(Student.class));
        return students;
    }

    @Override
    public Student findById(Integer id) {
        Student student = jdbcTemplate.queryForObject("SELECT * FROM student WHERE id=?", new Object[]{id}, new BeanPropertyRowMapper<>(Student.class));
        return student;
    }

    @Override
    public void add(Student student) {
        jdbcTemplate.update("INSERT INTO student(name, gender, age, major) VALUES(?,?,?,?)", student.getName(), student.getGender(), student.getAge(), student.getMajor());
    }

    @Override
    public void update(Student student) {
        jdbcTemplate.update("UPDATE student SET name=?, gender=?, age=?, major=? WHERE id=?", student.getName(), student.getGender(), student.getAge(), student.getMajor(), student.getId());
    }

    @Override
    public void delete(Integer id) {
        jdbcTemplate.update("DELETE FROM student WHERE id=?", id);
    }
}

4. 学生Service接口

public interface StudentService {
    List<Student> findAll();
    Student findById(Integer id);
    void add(Student student);
    void update(Student student);
    void delete(Integer id);
}

5. 学生Service实现类

@Service
public class StudentServiceImpl implements StudentService {
    @Autowired
    private StudentMapper studentMapper;

    @Override
    public List<Student> findAll() {
        return studentMapper.findAll();
    }

    @Override
    public Student findById(Integer id) {
        return studentMapper.findById(id);
    }

    @Override
    public void add(Student student) {
        studentMapper.add(student);
    }

    @Override
    public void update(Student student) {
        studentMapper.update(student);
    }

    @Override
    public void delete(Integer id) {
        studentMapper.delete(id);
    }
}

6. 学生Controller

@RestController
@RequestMapping("/students")
public class StudentController {
    @Autowired
    private StudentService studentService;

    @GetMapping("")
    public List<Student> list() {
        return studentService.findAll();
    }

    @GetMapping("/{id}")
    public Student findById(@PathVariable Integer id) {
        return studentService.findById(id);
    }

    @PostMapping("")
    public void add(@RequestBody Student student) {
        studentService.add(student);
    }

    @PutMapping("/{id}")
    public void update(@PathVariable Integer id, @RequestBody Student student) {
        student.setId(id);
        studentService.update(student);
    }

    @DeleteMapping("/{id}")
    public void delete(@PathVariable Integer id) {
        studentService.delete(id);
    }
}

前端代码（Vue.js）：

1. 学生列表页面

<template>
  <div>
    <h1>学生列表</h1>
    <table>
      <thead>
        <tr>
          <th>ID</th>
          <th>姓名</th>
          <th>性别</th>
          <th>年龄</th>
          <th>专业</th>
        </tr>
      </thead>
      <tbody>
        <tr v-for="student in students" :key="student.id">
          <td>{{ student.id }}</td>
          <td>{{ student.name }}</td>
          <td>{{ student.gender }}</td>
          <td>{{ student.age }}</td>
          <td>{{ student.major }}</td>
        </tr>
      </tbody>
    </table>
  </div>
</template>

<script>
import axios from 'axios'

export default {
  data() {
    return {
      students: []
    }
  },
  mounted() {
    axios.get('/students').then(response => {
      this.students = response.data
    })
  }
}
</script>

2. 学生详情页面

<template>
  <div>
    <h1>学生详情</h1>
    <div>ID：{{ student.id }}</div>
    <div>姓名：{{ student.name }}</div>
    <div>性别：{{ student.gender }}</div>
    <div>年龄：{{ student.age }}</div>
    <div>专业：{{ student.major }}</div>
  </div>
</template>

<script>
import axios from 'axios'

export default {
  data() {
    return {
      student: {}
    }
  },
  mounted() {
    const id = this.$route.params.id
    axios.get(`/students/${id}`).then(response => {
      this.student = response.data
    })
  }
}
</script>

3. 添加学生页面

<template>
  <div>
    <h1>添加学生</h1>
    <form @submit.prevent="add">
      <div>
        <label>姓名：</label>
        <input type="text" v-model="student.name" required>
      </div>
      <div>
        <label>性别：</label>
        <input type="radio" v-model="student.gender" value="男" required>男
        <input type="radio" v-model="student.gender" value="女" required>女
      </div>
      <div>
        <label>年龄：</label>
        <input type="number" v-model="student.age" required>
      </div>
      <div>
        <label>专业：</label>
        <input type="text" v-model="student.major" required>
      </div>
      <button type="submit">添加</button>
    </form>
  </div>
</template>

<script>
import axios from 'axios'

export default {
  data() {
    return {
      student: {
        name: '',
        gender: '',
        age: '',
        major: ''
      }
    }
  },
  methods: {
    add() {
      axios.post('/students', this.student).then(() => {
        this.$router.push('/')
      })
    }
  }
}
</script>

4. 修改学生页面

<template>
  <div>
    <h1>修改学生</h1>
    <form @submit.prevent="update">
      <div>
        <label>姓名：</label>
        <input type="text" v-model="student.name" required>
      </div>
      <div>
        <label>性别：</label>
        <input type="radio" v-model="student.gender" value="男" required>男
        <input type="radio" v-model="student.gender" value="女" required>女
      </div>
      <div>
        <label>年龄：</label>
        <input type="number" v-model="student.age" required>
      </div>
      <div>
        <label>专业：</label>
        <input type="text" v-model="student.major" required>
      </div>
      <button type="submit">保存</button>
    </form>
  </div>
</template>

<script>
import axios from 'axios'

export default {
  data() {
    return {
      student: {
        name: '',
        gender: '',
        age: '',
        major: ''
      }
    }
  },
  mounted() {
    const id = this.$route.params.id
    axios.get(`/students/${id}`).then(response => {
      this.student = response.data
    })
  },
  methods: {
    update() {
      const id = this.$route.params.id
      axios.put(`/students/${id}`, this.student).then(() => {
        this.$router.push('/')
      })
    }
  }
}
</script>

以上是一个简单的校园管理系统的前后端实现代码示例，具体实现还需要根据实际情况进行调整。
