从 Spring 3 升级到 Spring 5 - 现在自动装配出错

Question

有一个项目要升级 Java，weblogic 并且最终在我们的一个网络应用程序中 spring。曾经是 java 6，weblogic 10 和 spring 3。移动到 java 8，weblogic 12 和 spring 5.

在编译时经历了很多依赖地狱并且不得不重构一些已贬值的 spring 类我已经开始构建它了。

而这才是真正的问题开始的时候。

部署应用程序时出现以下异常。

组件是：

@Component
@Qualifier("healthPlanCheckoutFunnelStateHolderMapper")
public class HealthPlanCheckoutFunnelStateHolderMapper extends CommonHealthCheckoutFunnelStateHolderMapper<HealthPlanCheckoutBean>
{
    @Override
    protected HealthPlanCheckoutBean createBean() {
        return new HealthPlanCheckoutBean();
    }
}

并且该组件的自动装配是：

@Autowired
@Qualifier("healthPlanCheckoutFunnelStateHolderMapper")
private FunnelStateHolderMapper<HealthPlanCheckoutBean, HealthPlanFunnelStateHolder> funnelStateHolderMapper;

FunnelStateHolderMapper 接口

/**
 * Interface defines methods for mapping to and from a {@link FunnelStateHolder}. This is the top level mapper that
 * should be used by each controller for handling GET and POST requests. The implementation may delegate to other
 * underlying mappers but this should always be the interface to which the controller talks.
 */
public interface FunnelStateHolderMapper<B, F extends FunnelStateHolder> {

    B toScreenBean(F funnelStateHolder);

    F fromScreenBean(F funnelStateHolder, B screenBean);
}

配置中有组件扫描，其中包含此代码所在的包。

这在 spring 3 上运行良好，但自从更改为 spring 5 后，就出现了这个问题。我想可能是我必须做一些重构才能让它编译导致这个问题，但我不这么认为。 None 个包含上述代码的文件已更新。

到目前为止，我还没有更新任何 spring 配置。 spring 3 和 spring 5 搜索组件的方式有区别吗？

Answer 1

字段

private FunnelStateHolderMapper<...> funnelStateHolderMapper;

不是的@Component/@Qualifier注解class

的同类型

HealthPlanCheckoutFunnelStateHolderMapper

你不能期望 Spring 到 @Autowire 会抛出 compile/runtime 错误的东西.

如果 HealthPlanCheckoutFunnelStateHolderMapper 是层次结构的一部分，请显示。
