您提供的代码片段不完整，EmployeeService类的最后部分被截断了。以下是完整的EmployeeService实现： ```java package com.dfxy.service; import com.dfxy.mapper.EmployeeMapper; import com.dfxy.model.Employee; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import java.util.List; @Service public class EmployeeService { @Autowired private EmployeeMapper employeeMapper; public Employee getEmployeeById(Integer id) { return employeeMapper.getEmployeeById(id); } public void addEmployee(Employee employee) { employeeMapper.addEmployee(employee); } public void updateEmployee(Employee employee) { employeeMapper.updateEmployee(employee); } public void deleteEmployee(Integer id) { employeeMapper.deleteEmployee(id); } public List<Employee> getAllEmployees() { return employeeMapper.getAllEmployees(); } } ``` 这段代码实现了： 1. 通过EmployeeMapper与数据库交互 2. 提供基本的CRUD操作 3. 使用Spring的@Service注解标记为服务层组件 4. 通过@Autowired自动注入EmployeeMapper 完整的代码结构包含： - Controller层处理HTTP请求 - Service层实现业务逻辑 - Mapper层处理数据库操作 - Model层定义数据实体 如果需要任何其他部分的补充或解释，请告诉我。 [2025-04-21 11:41:02 | AI问答 | 282点数解答]
