在自定义组件中获取spring底层组件

public class Candy implements ApplicationContextAware, BeanNameAware, EmbeddedValueResolverAware {
    //bean的名称
    private String name;
    //容器
    private ApplicationContext applicationContext;
    //配置文件中的值
    private String nickname;

    @Override
    public void setBeanName(String name) {
        this.name = name;
    }
    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        this.applicationContext = applicationContext;
    }
    @Override
    public void setEmbeddedValueResolver(StringValueResolver resolver) {
        this.nickname = resolver.resolveStringValue("${bottle.nickname}");
    }
}
