解决At least one JAR was scanned for TLDs yet contained no TLDs. 问题

启动tomcat运行项目时，总是提示：

At least one JAR was scanned for TLDs yet contained no TLDs. Enable debug logging for this logger for a complete list of JARs that were scanned but no TLDs were found in them. Skipping unneeded JARs during scanning can improve startup time and JSP compilation time.

解决方案：
pom.xml中添加：

<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
<version>1.2</version>
</dependency>

之前自己pom.xml中导入的为：

<dependency>
<groupId>jstl</groupId>
<artifactId>jstl</artifactId>
<version>1.2</version>
</dependency>

因此，一直报错。
