解決At least one JAR was scanned for TLDs yet contained no TLDs. 問題

啟動tomcat運行項目時，總是提示：

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.

解決方案：
pom.xml中添加：

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

之前自己pom.xml中導入的為：

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

因此，一直報錯。
