Answer 1

Consider using another XML parser or at least newer version of dom4j, for example version 2.1.1, since it is better compatible with Java8.

Also simplify your mybatis config (without classpath: or invalid classpath*: prefix):

mybatis.config-location: mybatis-config.xml
mybatis.mapper-locations: mapper/*.xml
