> Tomcat启动提示At least one JAR was scanned for TLDs yet contained no TLDs

tomcat启动速度总是很慢，检查后发现tomcat启动时总是卡在这个地方  
经查阅得知Tomcat在启动过程中加载众多jar文件，默认会对其做 TLDs 扫描，\{CATALINA-HOME\}/logs/catalina.xxxx-xx-xx.log文件中会出现大量下面的 log：

### 修改配置 ###

1.打开tomcat安装目录/conf/catalina.properties  
2.找到代码`tomcat.util.scan.StandardJarScanFilter.jarsToScan=\`  
3.这行代码下面的jar包的都是需要扫描的，这也是导致tomcat启动过慢的元凶，所以删除下面的jar包即可  
4.将`tomcat.util.scan.StandardJarScanFilter.jarsToScan=\`修改为`tomcat.util.scan.StandardJarScanFilter.jarsToSkip=*.jar`  
5.修改完之后保存回到eclipse删除以前的tomcat配置，并重新配置
