java - @Repository 的 @Autowire 失败

Question

我是一名java开发人员，正在使用公司所需的自定义框架，该框架基于spring。我设法让旧版本工作，但这个新版本的 @Repository 有问题，尽管 bean 正在被扫描，但它不能是 @Autowired。

这是错误

我可能错过了一些东西，但我看不到它。

提前致谢。

您的 JobInvoiceRepositoryImpl 类实现 CustomJobInvoiceRepository 接口(interface)并使用 @Transactional 进行注释。

Spring AOP 事务基础架构检测其事务性并创建一个事务性 JDK 代理，该代理实现 CustomJobInvoiceRepository 并委托(delegate)给 JobInvoiceRepositoryImpl。

应用程序上下文中的实际 bean 不再是 JobInvoiceRepositoryImpl，而是一个代理。

您不能注入(inject) JobInvoiceRepositoryImpl，而是使用如下接口(interface)

@Service
public class JobInvoiceServiceImpl implements JobInvoiceService {

    @Autowired
    private CustomJobInvoiceRepository jobInvoiceRepository;

    @Override
    public List<JobInvoiceBean> getAllJobInvoice() {
        return jobInvoiceRepository.getAllInvoices();
    }

}

否则指示 Spring 使用 CGLIB 例如基于类的代理

@EnableTransactionManagement(proxyTragetClass = true) 

或 xml 中的等效项

<tx:annotation-driven proxy-target-class="true"/>
