Tomcat9在CentOS7上启动慢解决办法，实测可行

1.修改jdk目录下的java.security文件

vim /usr/lib/jvm/jdk1.8.0/jre/lib/security/java.security

将如下配置
securerandom.source=file:/dev/random

改为
securerandom.source=file:/dev/urandom

2.修改tomcat9下conf的catalina.properties

将tomcat.util.scan.StandardJarScanFilter.jarsToSkip=后面加载的jar包删除

改为tomcat.util.scan.StandardJarScanFilter.jarsToSkip=*.jar
