java - @Repository的@Autowire失败

我是一名Java开发人员，使用的是公司的必需框架，该框架基于Spring。我设法使其旧版本正常工作，但是此新发行版的@Repository存在问题，尽管正在扫描Bean，但无法将@Autowired转换为问题。

这是错误

我可能缺少某些东西，但看不到。

提前致谢。

最佳答案

您的JobInvoiceRepositoryImpl类实现CustomJobInvoiceRepository接口，并使用@Transactional进行注释。

Spring AOP事务性基础结构检测到其事务性，并创建一个事务性JDK代理，该代理实现CustomJobInvoiceRepository并委托给JobInvoiceRepositoryImpl。

应用程序上下文中的实际bean不再是JobInvoiceRepositoryImpl而是代理。

您不能注入JobInvoiceRepositoryImpl而是使用如下界面

@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使用基于类的代理，例如

@EnableTransactionManagement(proxyTragetClass = true)

或等价于xml

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