SpringBoot项目获取ApplicationContext

1. 直接使用@Autowired注入

   @Autowired
   private ApplicationContext ctx;
   

2. 实现ApplicationContextAware接口，重写setApplicationContext方法（推荐）

   @Component
   public class ApplicationContextProvider implements ApplicationContextAware{
       
       private ApplicationContext applicationContext;
   
       @Override
       public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
           this.applicationContext = applicationContext;
       }
       
       public ApplicationContext getApplicationContext() {
           return applicationContext;
       }
   }
   

3. 继承抽象类ApplicationObjectSupport

   @Component
   public class DashboardServiceConfig extends ApplicationObjectSupport {
   
   	private ApplicationContext ctx;
   
   	@Override
   	protected void initApplicationContext(ApplicationContext context) throws BeansException {
   		super.initApplicationContext(context);
   		ctx = context;
   	}
