netty的handler在注入spring管理下的bean时出现了空指针，如下：

63行代码：

不知道是什么原因引起的，下面是解决办法：
1.首先写一个spring的工具类

@Component
public class SpringUtil implements ApplicationContextAware {private static ApplicationContext applicationContext;@Overridepublic void setApplicationContext(ApplicationContext applicationContext) throws BeansException {if(SpringUtil.applicationContext == null) {SpringUtil.applicationContext = applicationContext;}}//获取applicationContextpublic static ApplicationContext getApplicationContext() {return applicationContext;}//通过name获取 Bean.public static Object getBean(String name){return getApplicationContext().getBean(name);}//通过class获取Bean.public static <T> T getBean(Class<T> clazz){return getApplicationContext().getBean(clazz);}//通过name,以及Clazz返回指定的Beanpublic static <T> T getBean(String name,Class<T> clazz){return getApplicationContext().getBean(name, clazz);}}

2.更改注入方法：

    //用此方法代替掉autowired注入private static ClientLogService clientLogService;static {clientLogService = SpringUtil.getBean(ClientLogService.class);}
