关于Springboot如何获取IOC容器

SpringApplication.run(Application.class, args);

public class SpringApplication {
    public static void main(String[] args) {
        ApplicationContext applicationContext = SpringApplication.run(Application.class, args);
        Object startSerive = applicationContext.getBean("startSerive");
    }
}

public class SpringContextUtil implements ApplicationContextAware {
    private static ApplicationContext applicationContext;
    public SpringContextUtil() {
    }
    /**
     * 设置上下文
     * @param applicationContext
     * @throws BeansException
     */
    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        if (SpringContextUtil.applicationContext == null) {
            SpringContextUtil.applicationContext = applicationContext;
        }
    }
    /**
     * 获取上下文
     * @return
     */
    public static ApplicationContext getApplicationContext() {
        return applicationContext;
    }
    /**
     * 通过名字获取上下文中的bean
     * @param name
     * @return
     */
    public static Object getBean(String name){
        return applicationContext.getBean(name);
    }
    /**
     * 通过类型获取上下文中的bean
     * @param requiredType
     * @return
     */
    public static Object getBean(Class<?> requiredType){
        return applicationContext.getBean(requiredType);
    }
}

@SpringBootApplication
@Import({SpringContextUtil.class})
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}
