'org.springframework.web.filter.CharacterEncodingFilter' is not assignable to 'javax.servlet.Filter'

记录一下…
今天在配置web.xml文件的过滤器时一直报这个错,之前貌似没碰到过,将处理方法记录一下:
'org.springframework.web.filter.CharacterEncodingFilter' is not assignable to 'javax.servlet.Filter'

解决办法:

File–>Project Structer–>选中项目–>点击+号–>将Tomcat添加进来–>apply–>OK 'org.springframework.web.filter.CharacterEncodingFilter' is not assignable to 'javax.servlet.Filter'
