Use the version from parent pom.xml where possible
| SqlSession sqlSession; | ||
| MapperPlayer playerMapper; | ||
| sqlSession = Mybatis3Utils.getCurrentSqlSession(); | ||

This can be reduced to 2 lines. Use var where possible.
| final Player player = new Player(); | ||
| player.setName("player1"); | ||
| playerMapper.insertPlayer(player); | ||
| sqlSession.commit(); |
