springboot打成war包后，在tomcat中启动时间不稳定，时慢时快

Question

昨天的启动日志：

19-Apr-2018 17:55:53.410 INFO [main] org.apache.catalina.startup.HostConfig.deployWAR Deploying web application archive [/root/testtomcat/apache-tomcat-9.0.7/webapps/dingdongfm.war]
19-Apr-2018 17:55:56.317 INFO [main] org.apache.jasper.servlet.TldScanner.scanJars 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.《-----一直卡在这里

springboot打成war包部署到tomcat上，昨天和今天的启动时间差很多。环境没有动过，tomcat关于熵池的配置都是一致的。有人碰到过这个问题么？

Answer 1

"tomcat关于熵池的配置都是一致的"。这个配置已经改过且生效了。

Answer 2

不太懂你的意思，能具体说下么？

Answer 4

看下你的缓存机制

Answer 5

同一个web应用，在同一台服务器的同一个tomcat上运行，昨天和今天的启动时间差别很大。昨天每次启动基本都在4分钟左右，今天在40秒左右。想知道什么原因，但是没有定位思路，所以来这请教。

Answer 6

没明白你要表达的意思

Answer 7

你的意思是直接用内嵌的容器启动？

Answer 8

内置的有坑。。。

@zjg23 : 对啊

Answer 11

既然用了springboot，为什么还要用tomcat？这不是脱裤子放屁嘛！
