我有一个组件

@Component
public class ExpenseCalculator {
    @Autowired
    private TaxService taxService;

    @Autowired
    private EmployeeService employeeService;

    @Autowired
    @Lazy
    private PurchaseService purchaseService;
}

在这里，只有当使用purchaseService的代码的任何部分被调用（？）时，PurchaseService才被初始化。
现在我必须将ExpenseCalculator移动到一个配置类（它没有@Component注解）

@Configuration
public class ExpenseConfig {
    @Bean
    @Lazy
    public ExpenseCalculator getExpenseCalculator(
        TaxService taxService, 
        EmployeeService employeeService,
        PurchaseService purchaseService
    ) {
        return new ExpenseCalculator(taxService, employeeService, purchaseService);
    }
}

但是当ExpenseCalculator初始化时，purchaseService不再是@Lazy组件，purchaseService也被初始化。
有没有什么方法可以使用configuration延迟初始化purchaseService？
