springboot 拦截器中 @Autowire注入不进去

1. if (null ==redisUtil){
       BeanFactory factory = WebApplicationContextUtils.getRequiredWebApplicationContext(request.getServletContext());
       redisUtil = (RedisUtil) factory.getBean("redisUtil");
   }

      在别的博客中看到的方法 我的是redisUtil注入不进来 然后这样自己去取 就ok了 具体的出处不明白了 ：）

   if (null ==redisUtil){
       BeanFactory factory = WebApplicationContextUtils.getRequiredWebApplicationContext(request.getServletContext());
       redisUtil = (RedisUtil) factory.getBean("redisUtil");
   }

 

 

if (null ==redisUtil){
    BeanFactory factory = WebApplicationContextUtils.getRequiredWebApplicationContext(request.getServletContext());
    redisUtil = (RedisUtil) factory.getBean("redisUtil");

}
