本文详细介绍了在Java Spring Boot框架中如何通过注入DAO层和Service层实现用户登录功能，包括登录验证逻辑及返回状态代码。

/**@Component（不推荐使用）、@Repository Dao层、@Service Service层、@Controller action层*/
@Resource
private EmployeeDao employeeDao;

public void setEmployeeDao(EmployeeDao employeeDao) {
this.employeeDao = employeeDao;
}

public EmployeeDao getEmployeeDao() {
return employeeDao;
}

@Override
public int login(Employee employee) {
List<Employee> employeeList= employeeDao.selectEmployee(employee);
if(employeeList.isEmpty()){
return -1;
}
return 1;
}

@Autowired @Qualifier("employeeDao")
private EmployeeDao employeeDao;

public void setEmployeeDao(EmployeeDao employeeDao) {
this.employeeDao = employeeDao;
}

public EmployeeDao getEmployeeDao() {
return employeeDao;
}

@Override
public int login(Employee employee) {
List<Employee> employeeList= employeeDao.selectEmployee(employee);
if(employeeList.isEmpty()){
return -1;
}
return 1;
}
