Spring boot随时获取ApplicationContex

@Service
public class SpringManager implements ApplicationListener<ContextRefreshedEvent> {
    private static ApplicationContext applicationContext = null;
    @Override
    public void onApplicationEvent(ContextRefreshedEvent event) {
        if(applicationContext == null){
            applicationContext = event.getApplicationContext();
        }
    }
    /*ApplicationContext context= ContextLoader.getCurrentWebApplicationContext();//尝试下这个方法*/
    public static ApplicationContext getApplicationContext() {
        return applicationContext;
    }
}

@Service
public class SpringManager implements ApplicationListener<ContextRefreshedEvent> {
    private static ApplicationContext applicationContext = null;
    @Override
    public void onApplicationEvent(ContextRefreshedEvent event) {
        if(applicationContext == null){
            applicationContext = event.getApplicationContext();
        }
    }
    /*ApplicationContext context= ContextLoader.getCurrentWebApplicationContext();//尝试下这个方法*/
    public static ApplicationContext getApplicationContext() {
        return applicationContext;
    }
}

或者
@Service
public class SpringTool implements ApplicationContextAware {
    private static ApplicationContext context = null;
    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        context = applicationContext;
    }
    public static ApplicationContext getApplicationContext() {
        return context;
    }


}

或者
@Service
public class SpringTool implements ApplicationContextAware {
    private static ApplicationContext context = null;
	@Override
	public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
		context = applicationContext;
	}
    public static ApplicationContext getApplicationContext() {
        return context;
    }
}

或者直接
    @Autowired
    ApplicationContext context;

或者直接

@Autowired

ApplicationContext context;
