帮我写基于springboot+vue考勤管理功能代码

好的，我会尝试帮您编写这部分代码。以下是一个简单的代码示例，供您参考：

后端代码（基于 Spring Boot）：

@RestController
public class AttendanceController {

    @Autowired
    private AttendanceService attendanceService;

    @PostMapping("/attendance")
    public void addAttendance(@RequestBody Attendance attendance) {
        attendanceService.addAttendance(attendance);
    }

    @GetMapping("/attendance")
    public List<Attendance> getAllAttendances() {
        return attendanceService.getAllAttendances();
    }

    @GetMapping("/attendance/{id}")
    public Attendance getAttendanceById(@PathVariable("id") Long id) {
        return attendanceService.getAttendanceById(id);
    }

    @PutMapping("/attendance/{id}")
    public void updateAttendance(@PathVariable("id") Long id, @RequestBody Attendance attendance) {
        attendanceService.updateAttendance(id, attendance);
    }

    @DeleteMapping("/attendance/{id}")
    public void deleteAttendance(@PathVariable("id") Long id) {
        attendanceService.deleteAttendance(id);
    }
}

@Service
public class AttendanceServiceImpl implements AttendanceService {

    @Autowired
    private AttendanceRepository attendanceRepository;

    @Override
    public void addAttendance(Attendance attendance) {
        attendanceRepository.save(attendance);
    }

    @Override
    public List<Attendance> getAllAttendances() {
        return attendanceRepository.findAll();
    }

    @Override
    public Attendance getAttendanceById(Long id) {
        return attendanceRepository.findById(id).orElse(null);
    }

    @Override
    public void updateAttendance(Long id, Attendance attendance) {
        Attendance existingAttendance = attendanceRepository.findById(id).orElse(null);
        if(existingAttendance != null) {
            existingAttendance.setEmployeeId(attendance.getEmployeeId());
            existingAttendance.setDate(attendance.getDate());
            existingAttendance.setStatus(attendance.getStatus());
            attendanceRepository.save(existingAttendance);
        }
    }

    @Override
    public void deleteAttendance(Long id) {
        attendanceRepository.deleteById(id);
    }
}

@Entity
@Table(name = "attendance")
public class Attendance {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    private Long employeeId;

    private LocalDate date;

    private AttendanceStatus status;

    // getters and setters
}

public enum AttendanceStatus {
    PRESENT, ABSENT, LEAVE
}

public interface AttendanceRepository extends JpaRepository<Attendance, Long> {

}

前端代码（基于 Vue.js）：

<template>
  <div>
    <h1>考勤管理</h1>
    <router-link to="/add-attendance">新增考勤</router-link>
    <table>
      <thead>
        <tr>
          <th>ID</th>
          <th>员工ID</th>
          <th>日期</th>
          <th>状态</th>
          <th>操作</th>
        </tr>
      </thead>
      <tbody>
        <tr v-for="(attendance, index) in attendances" :key="attendance.id">
          <td>{{ attendance.id }}</td>
          <td>{{ attendance.employeeId }}</td>
          <td>{{ attendance.date }}</td>
          <td>{{ attendance.status }}</td>
          <td>
            <router-link :to="{ name: 'edit-attendance', params: { id: attendance.id } }">编辑</router-link>
            <button @click="deleteAttendance(index, attendance.id)">删除</button>
          </td>
        </tr>
      </tbody>
    </table>
  </div>
</template>

<script>
import axios from 'axios'

export default {
  name: 'AttendanceList',
  data() {
    return {
      attendances: [],
    }
  },
  mounted() {
    this.loadAttendances()
  },
  methods: {
    loadAttendances() {
      axios.get('/attendance')
        .then(response => {
          this.attendances = response.data
        })
    },
    deleteAttendance(index, id) {
      axios.delete(`/attendance/${id}`)
        .then(() => {
          this.attendances.splice(index, 1)
        })
    },
  },
}
</script>
