如果在自动装配中使用（required = false），则@Autowired与@Qualifier不起作用

Question

我正在尝试将@Autowired与@Qualifier一起使用，在这样的Autowired批注中具有required = false

@Autowired(required=false)
@Qualifier("myValidator")
private MyValidatorClass validator;

如果我没有在上下文xml文件中初始化此特定的bean，则它不应给出错误。

根据我的业务需求，我希望在属性上同时添加两个注释。我是春季新手，请帮助我解决此问题。
