SqlSession [org.apache.ibatis.session.defaults.DefaultSqlSession@ec18b38] was not registered for synchronization because synchronization is not active JDBC Connection [com.mysql.jdbc.JDBC4Connection@749d2bf5] will not be managed by Spring原因：出现报错就是因为某个字段是null，而数据库设计的时候，这个字段不能为null，所以报错，所以只需要传个数据给该字段就行。
