企业人员管理系统到底是怎么回事?一文搞懂

// 员工实体类定义
public class Employee
{
    public int Id { get; set; }
    public string EmployeeId { get; set; }
    public string Name { get; set; }
    public string Department { get; set; }
    public string Position { get; set; }
    public DateTime HireDate { get; set; }
    public string Email { get; set; }
    public string Phone { get; set; }
    
    // 导航属性
    public virtual ICollection AttendanceRecords { get; set; }
    public virtual ICollection SalaryRecords { get; set; }
}

// 考勤记录实体
public class AttendanceRecord
{
    public int Id { get; set; }
    public int EmployeeId { get; set; }
    public DateTime CheckInTime { get; set; }
    public DateTime CheckOutTime { get; set; }
    public AttendanceStatus Status { get; set; }
    
    // 外键关系
    public virtual Employee Employee { get; set; }
}

// 员工管理前端组件
class EmployeeManagement extends React.Component {
  state = {
    employees: [],
    loading: false,
    searchKeyword: ''
  };
  
  // 获取员工列表
  fetchEmployees = async () => {
    this.setState({ loading: true });
    try {
      const response = await fetch('/api/employees');
      const data = await response.json();
      this.setState({ employees: data, loading: false });
    } catch (error) {
      console.error('获取员工数据失败:', error);
      this.setState({ loading: false });
    }
  };
  
  // 搜索员工
  handleSearch = (keyword) => {
    this.setState({ searchKeyword: keyword });
    // 实现搜索逻辑
  };
  
  render() {
    const { employees, loading, searchKeyword } = this.state;
    
    return (
      

        
        {loading ?  : }
      
    );
  }
}
