今天遇到一个问题，要在一个tomcat中部署多个war文件，在此之前对tomcat的了解就是，默认配置下，在webapp文件夹下新建的文件夹即可通过ip+端口+文件夹名 被访问到，所以多个war包直接扔里就应该是没问题，但是：

经过查询才知道，如果多个springboot项目，都通过atomikos配置了多数据源，在同一服务器主机上启动运行，就会报错：
com.atomikos.recovery.LogException: Log already in use?
出错原因：atomikos默认日志打印：tomcat\transaction-logs\tmlog.lck 和 tomcat\transaction-logs\tmlog0.log，导致多项目共用同一日志文件，前面的项目将会锁定文件，后面启动的项目将会无法写入。所以解决方案就有了，既然是公用同一个日志文件导致的，那就自己用自己的不就好了，修改文件名称或路径，或者干脆不用日志，于是乎，解决方案就是：
1.在配置文件中修改日志文件名称，一个项目一个不重复，spring.jta.atomikos.properties.log-base-name=name1（name2，name3.。。）
2.在配置文件中修改日志文件路径，一个项目一个不重复，spring.jta.atomikos.properties.log-base-dir=./log/name1（./log/name2,name3..）
3.在配置文件中关闭日志打印（可以开一个），spring.jta.atomikos.properties.enable-logging=false
