自动连接到列表中时的Bean顺序 [英] Bean order when autowired into list

问题描述

我已经定义了接口IWorker及其一些实现，分别为WorkerA和WorkerB，均用@Component注释.

I have defined an interface IWorker and some implementations of it as WorkerA and WorkerB, both annotated with @Component.

然后我通过以下方式将它们自动连接到我的应用程序中:

I then autowire them into my app via:

@Autowired
private List<IWorker> workers = new ArrayList<IWorker>();

• 根据什么顺序将工人放入列表中?

  • From what does the order the workers are put into the list depend on?

    如何通过我的applicationContext.xml将未使用@Component注释的其他WorkerC和WorkerD(也是IWorker的实现)自动连接到同一列表中?

    How can I let additional WorkerC and WorkerD (also implementations of IWorker) not annotated with @Component be autowired into the same list via my applicationContext.xml?

    是否保留了xml中WorkerC和WorkerD的顺序?

    Is the order of WorkerC and WorkerD from the xml preserved?

    我是否可以依靠规则将工作人员A，B，C和D放入列表的顺序?

    Is there a rule I can rely on in which order worker A, B, C and D will be put into the list?

    推荐答案

    如果要在Spring注入的List中对这些依赖项进行排序，请使用@Order批注.

    If you want to order these dependencies in the List injected by Spring, then use @Order annotation.
