Intellij搭建springmvc常见问题解决方案

注意是maven的webapp：

选择maven下一步下一步。

maven下载过慢在setting中加入镜像。 我也有疑问这是什么鬼格式，但是证明，格式不用调整，直接粘贴进去：

<mirror>
　　 <id>
　　　　nexus-aliyun
　　 </id>
<mirrorOf>
*
</mirrorOf>
<name>
Nexus aliyun
</name>
<url>
http://maven.aliyun.com/nexus/content/groups/public
</url>
</mirror>

我在这里踩了一个特郁闷的坑，注意看这里，没有package war, 这里有毒，导致我的tomcat一直加不进去artifacts

暂时就是这个鬼样子的结构，手动补全结构，

调整一下包：

加入和pom中的依赖 和 web.xml和 springmvc.xml

注意这里别丢了 pom:

pom.xml:

<!--能访问到静态资源,但是URL和控制器中对应的方法没有映射关系-->
<mvc:default-servlet-handler/>

</beans>

这已经是很精简版的了。

配置tomcat， 我在这里遇到了问题，记录详细点：

（上面删除了mymvc:war也是可以的。图就懒得替换了。）

ok

启动tomcat成功：

而且注意这里不要用http://localhost:8080/ 去试，会404.
