OncePerRequestFilter接口看注入userServiceBean吗

根据您提供的引用内容，OncePerRequestFilter接口本身不会对注入的userServiceBean进行处理。OncePerRequestFilter是Spring Boot中的一个过滤器抽象类，主要用于在每次请求时执行一次过滤操作。OncePerRequestFilter的子类可以通过注入userServiceBean来使用该服务，但是是否成功注入serviceBean取决于具体实现类的配置。如果您发现在继承OncePerRequestFilter的类中，userService一直为null，可能是由于未正确配置依赖注入导致的。请确保在您的类中正确配置了userServiceBean的注入方式，并且容器能够正确识别和注入该依赖。同时，还需要确保userServiceBean已被正确实例化和初始化，以便在注入时能够成功引用。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
