Tomcat9控制台中文乱码和缓存不足

1、Tomcat9.0.2之后控制台出现中文乱码

Tomcat9.0.2之后在${CATALINA_HOME}/conf/logging.properties中增加了一句java.util.logging.ConsoleHandler.encoding = UTF-8，导致在有些windows系统中出现中文乱码。修改方法：

1、改成GBK后问题解决。

2、把这句话去掉

2、springboot tomcat 缓存

org.apache.catalina.webresources.Cache.getResource 无法将位于[/WEB-INF/classes/templates/]的资源添加到Web应用程序[/b]的缓存中，因为在清除过期缓存条目后可用空间仍不足 - 请考虑增加缓存的最大空间。

org.apache.catalina.webresources.Cache.getResource Unable to add the resource at [**] to the cache because there was insufficient free space available after evicting expired cache entries - consider increasing the maximum size of the cache

${CATALINA_HOME}/conf/context.xml
