<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
<filter>
<filter-name>MyFilter</filter-name>
<filter-class>/struts2-day01/app01/MyFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>MyFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

</web-app>

[紫雨冰人]

没有找到这个类 这个类应该是个自定义过滤器的。 struts2-day01.app01.MyFilter 应该在struts2-day01.app01包下有MyFilter .java 文件。 如果是使用struts2 应该配置struts2的核心过滤器 而不是自定义的这个过去器

[逗号xzlhs]

这个错误很泛滥的，你要看具体的

[执笔记忆的空白]

为什么filter-class 里面配置 /struts2-day01/app01/MyFilter？

<filter-class>
            org.springframework.web.filter.CharacterEncodingFilter
        </filter-class>

这个里面要配置class路径，而不是你映射路径

[Giberson1]

看报错第一行

at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1680)

看它涉及到什么类了。

谢谢各位大神

[我的努力我的进步]

类没找到，问题都说的这么明显了，去那个包下找 那个类
