java.lang.ClassNotFoundException 过滤器，启动tomcat报错如下

[云风_]

ps：能正常解决编码问题（编码过滤），就是出现以下错误，求怎么解决

[夜空中苦逼的程序员]

com.zzab.yf.filter01.Encoding 没有找到... 自己配置的过滤器 url-pattern 指定的类的完整限定名错了

应该就是这样

[oh_Maxy]

LZ看看com.zzab.yf.filter01.Encoding这个类在服务器工程下能否找到对应.class文件。

我的意思是工程部署没把相关类部署进去。

[键盘上的舞者_java]

先看看有没有这个类，然后重新部署

[w_k_n_h]

类找到了的 而且安装Ctrl+鼠标右键可以点击跳到那个类中

[w_k_n_h]

如果删除过滤器配置文件： <filter> <filter-name>encoding1</filter-name> <filter-class>filter.EncodingFilter</filter-class> </filter> <filter-mapping> <filter-name>encoding1</filter-name> <url-pattern>*.do</url-pattern> </filter-mapping> 可以正常运行
