这个 Bean 没有配置 xml 文件
或者没有配置 Bean 注解
或者容器启动没有扫描到改类，packageScan 配置不对 仔细检查下cn.itcast.goods.web.filter.LoginFilter 这个类是否有问题，以及配置这个类以及包的配置文件或注解是否正确，问题应该就能解决了。:loveliness: 前面两层楼的说得对 Vvvvvoid 发表于 2021-12-9 16:08

看了下，没啥问题啊 Goldrepo 发表于 2021-12-9 17:24

编辑了，回复错了 987857149 发表于 2021-12-9 18:42

检查下报错的环境是不是少了jar包，看你这个类是继承javax.servlet.Filter（来自servlet-api-XXX.jar）
java.lang.ClassNotFoundException: cn.itcast.goods.web.filter.LoginFilter
删除一下缓存重新启动一下 这个报错很明显了，你用到了这个类的依赖，但是在容器中没有找到这个类的实例，应该是在项目启动的时候没有加载类对象到容器中，看下是不是注解或者配置文件没加
