Maven 错误:包javax.servlet不存在
我正试图使用jsf 2在我的web应用程序中实现登录过滤器,遵循以下指南: 在我编译了我的过滤器并在“web inf/classes”中添加了.class之后(正如指南所说),过滤器工作了,但我把错误的url重定向到登录页面,所以我从文件夹(web inf/classes)中删除了filter.class,并尝试再次编译该项目,但失败了,从那以后我得到了“package javax.servlet不存在” 这很奇怪,因为在它工作之前,我在pom.xml中有javax.servlet。。我试图清理这个项目,但什么也没有 这是我的筛选器类:Maven 错误:包javax.servlet不存在,maven,servlet-filters,Maven,Servlet Filters,我正试图使用jsf 2在我的web应用程序中实现登录过滤器,遵循以下指南: 在我编译了我的过滤器并在“web inf/classes”中添加了.class之后(正如指南所说),过滤器工作了,但我把错误的url重定向到登录页面,所以我从文件夹(web inf/classes)中删除了filter.class,并尝试再次编译该项目,但失败了,从那以后我得到了“package javax.servlet不存在” 这很奇怪,因为在它工作之前,我在pom.xml中有javax.servlet。。我试图清
