这个问题已被问过几次，我看了很多。我尝试了所有的建议，加上一些。首先，我将显示我的代码并告诉您我是如何尝试调试它的。

WARNING: No mapping found for HTTP request with URI [/SpringMVCpractice/WEB-INF/jsps/index.jsp] in DispatcherServlet with name 'dispatcher'
现在我试图像这样改变servlet-mapping，因为上面的警告说没有找到带有URI [/ SpringMVCpractice /]的HTTP请求的映射。
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>/SpringMVCpractice/*</url-pattern>
</servlet-mapping>
然后警告消失但我仍然收到404错误。

是的，这确实有效，但为什么呢？这不仅仅是我的页面的样子：
1 个答案:
答案 0 :(得分：0)
您应该在<mvc:default-servlet-handler />中添加dispatcher-servlet.xml。添加此内容后应该有效。
