当我们
 

    @Autowired
    private IBroadcastingEquipmentOnService iBroadcastingEquipmentOnService;

注入失败的时候如果你的类并不是正常controller    可以使用下面的方式  通过class获取Bean
当有需要的时候  复制下方代码  类名  SpringUtils    后  在需要调用的地方  使用下面的方式

SpringUtils.getBean(xxxxxx.class).getBroadcastingEquipmentById();

package sys_terminal.broadcastSDK.api;

import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;

public class SpringUtils implements ApplicationContextAware {

    private static ApplicationContext applicationContext;

    @SuppressWarnings("static-access")
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        this.applicationContext = applicationContext;
    }

    /**

      */
    public static ApplicationContext getApplicationContext() {
        return applicationContext;
    }

        return getApplicationContext().getBean(name);
    }
