springboot229基于Spring Boot的企业员工薪酬关系系统的设计

由于原始代码已经非常接近完整，以下是核心函数的示例，展示了如何使用Spring Data JPA和Spring Security实现员工信息的查询和修改：

@Service
public class EmployeeService {
 
    @Autowired
    private EmployeeRepository employeeRepository;
 
    @Autowired
    private DepartmentRepository departmentRepository;
 
    @Autowired
    private PositionRepository positionRepository;
 
    public List<Employee> getAllEmployees() {
        return employeeRepository.findAll();
    }
 
    public Employee getEmployeeById(Long id) {
        return employeeRepository.findById(id).orElse(null);
    }
 
    @Transactional
    public Employee updateEmployee(Long id, EmployeeDto employeeDto) {
        Employee employee = employeeRepository.findById(id).orElseThrow(() -> new RuntimeException("Employee not found"));
        Department department = departmentRepository.findById(employeeDto.getDepartment().getId())
                .orElseThrow(() -> new RuntimeException("Department not found"));
        Position position = positionRepository.findById(employeeDto.getPosition().getId())
                .orElseThrow(() -> new RuntimeException("Position not found"));
 
        employee.setName(employeeDto.getName());
        employee.setDepartment(department);
        employee.setPosition(position);
        employee.setHireDate(employeeDto.getHireDate());
        employee.setPhoneNumber(employeeDto.getPhoneNumber());
        employee.setEmail(employeeDto.getEmail());
        employee.setEnabled(employeeDto.isEnabled());
 
        return employeeRepository.save(employee);
    }
 
    // ... 其他方法略 ...
}

在这个示例中，我们定义了一个服务类EmployeeService，它使用自动装配的EmployeeRepository来查询和保存员工信息。updateEmployee方法接收一个员工ID和一个DTO对象，然后根据DTO中的信息更新对应员工的信息。这里使用了Spring Data JPA的查询方法findById，以及Spring的事务管理注解@Transactional来确保更新操作的完整性。
