启动tomcat后报了下面的错：

intellij idea 使用Tomcat部署的项目在哪里,为什么不在Tomcat的webapps目录下面  
首先说明怎么找到已经部署好的项目,再来解释原因.  
首先点击项目,右键点击Show in Explorer.

此时部署的web项目已经找到.  
intellij idea使用Tomcat部署项目后并不会把编译后的项目复制到tomcat的webapps目录下,但是它会把编译好的项目路径告诉Tomcat,让Tomcat来找到这个项目,其它的项目比如Tomcat的主页项目ROOT是打不开的,因为intellij idea 只让Tomcat运行了一个项目.  
接下来看一下war包的目录结构,也就是整个web项目编译后的目录结构

然后就去/WEB-INF/classes/去找是否生成了mvc.xml文件，一查才发现根本就没有生成，连config文件夹都没有，导致tomcat启动时根本就知道他的存在。  
接着我把config文件夹及其内部文件移到src文件夹中，接着重启tomacat服务器发现还是报错。

\*\*tomcat加载spring的配置文件默认位置是在/WEB-INF/下找springmvc.xml文件，\*\*而IDEA文件编译后生成的springmvc.xml配置文件放在/WEB-INF/classes/springmvc.xml，所以加载时找不到springmvc.xml文件  
解决方法：  
在web.xml配置文件加上

<param-name>contextConfigLocation</param-name>
                <param-value>classpath:config/springmvc.xml</param-value>
