开心最重要
在Tomcat中启动项目是出现java.lang.ClassNotFoundException: org.springframework.web的错误解决方式
1、点击 properties-----&Deployment Assembly-----&Add -& Java Build Path Entries -& Next------& Maven Dependencies -& Finish -& Apply -& OK2、Clean project and server. 重启server
没有更多推荐了，tomcat在发布项目的时候没有同时发布maven依赖所添加的jar包，所以找不到解决方法：设置一下eclipse：项目 && properties -& Deployment Assembly -& Add -& Java Build Path Entries -& 选择Maven Dependencies -& Finish -& OK把对应的Maven依赖包也发布到tomcat，调试时会自动把那些jar发布到指定目录下，tomcat也能找到那些jar了。

一般是项目的Maven Dependencies没有添加到项目的编译路径下。
解决办法：选中项目名称右键 --& Properties --& Deployment Assemby --& Add --& Java Build Path Entries --& Finish --& Apply --& OK
添加完成之后如下图所示：

java.lang.ClassNotFoundException: org.springframework.web.util.Log4jConfigListener
运行环境中没有导入jar包,仔细查看.classpath和.project文件,加入应有的jar包.
如果上述方式仍然不能找到原因,请尝试以下办法:
1,删除服务器下的工程,重新启动服务器;
2,如果不行,删除Server Runtime Environments下的server,重新建立一个server,发布工程;
3,如果还是不行,注销或重启系统,一般到这一步就可以解决了;

原因：项目编译的时候相应的jar包没有被引入
解决方法：右击项目，选择properties——deployment Assembly——add——java
Path Entries——maven Dependencies
重新编译项目即可
