IDEA spring-boot 綁定ApplicationContext

要獲取各種bean，需要用到 ApplicationContext

獲取它的引用方式是先綁定它：

@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;
    }
}

然後通過此類型的靜態方法 getContext 獲取。
