问题
整合Spring MVC由于用到jstl，所以引入jstl标签用的jar包，启动tomcat时控制台出现了如下的输出：

解决方法
由于standard.jar与jstl.jar需一起使用，但是jstl 1.2版本的就不需要这个standard.jar包了，而本人使用的正是jstl 1.2.jar这个jar包，去掉standard.jar文件后重启tomcat就不会再出现上述信息。
<dependency>
<groupId>taglibs</groupId>
<artifactId>standard</artifactId>
<version>1.1.2</version>
</dependency>
