web.xml配置如下：
<servlet>
<description></description>
<display-name>ArticleServlet</display-name>
<servlet-name>ArticleServlet</servlet-name>
<servlet-class>servlet.ArticleServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>ArticleServlet</servlet-name>
<url-pattern>/articleservlet</url-pattern>
</servlet-mapping>
[解决办法]
/articleservlet/*
[解决办法]
/articleservlet
如果你项目是blog
/blog/articleservlet
这2个试试
[解决办法]
改成这样：
- Java code
<servlet-mapping> <servlet-name>ArticleServlet</servlet-name> <url-pattern>/blog/admin/articleservlet</url-pattern> </servlet-mapping>
[解决办法]
404 错误 是页面没找到
你看看你的 XML servlet配置的路径是这么写得么
