IDEA spring-boot 绑定ApplicationContext

要获取各种bean，需要用到 ApplicationContext

获取它的引用方式是先绑定它：

@Component
public class AppContext implements ApplicationContextAware
{
    private static ApplicationContext context;

    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException
    {
        context = applicationContext;
    }

    public static ApplicationContext getContext()
    {
        return context;
    }
}

然后通过此类型的静态方法 getContext 获取。
