Answer 1

看下你的struts.xml 里面配置的
<action name="llll" class="..............BlogUsers"> <!-- 配置action的物理映射 -->

这种类型的句子 看看class有没有配置错路径，或者看看你的action文件名字是不是BlogUsers

还有种可能看看struts.xml 里面的namespace有没有弄错，要在jsp页面里面调用action的时候加上namespace的，如namespace=“test/” 你在表单跳转中action="test/....."要写成这样

Answer 2

是不是配置文件没写对？这个错误很常见的，用url重写了么？如果有看看url重写的配置文件，看看struts配置文件，再看看要定位的是execute方法还是自己定义的方法，还有在web.xml中配置的struts的后缀，是不是吧*.action改成别的了？等等。这个错误应该跟代码无关，配置或者访问路径问题。

Answer 3

BlogUsers在struts.xml中action配置有问题

Answer 4

BlogUsers在struts.xml中action配置有问题
