编译好的war包部署到tomcat时报错Element does not allow nested elements， 经过反复检查，发现是ehcache 依赖冲突造成的， `排除mybatis-ehcache的ehcache依赖后，war恢复正常，可以顺利的部署到Tomcat中，也可以使用jetty:run-exploded运行
报错日志如下：
org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘org.springframework.cache.interceptor.CacheInterceptor#0’: Cannot resolve reference to bean ‘cacheManager’ while setting bean property ‘cacheManager’; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘cacheManager’ defined in file [/home/donaldjohn/installed_software/apache-tomcat-8.5.15/webapps/zheng-upms-server/WEB-INF/classes/applicationContext-ehcache.xml]: Cannot resolve reference to bean ‘cacheManagerFactory’ while setting bean property ‘cacheManager’; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘cacheManagerFactory’ defined in file [/home/donaldjohn/installed_software/apache-tomcat-8.5.15/webapps/zheng-upms-server/WEB-INF/classes/applicationContext-ehcache.xml]: Invocation of init method failed; nested exception is net.sf.ehcache.CacheException: Error configuring from input stream.
