日志卡在：
[18:18:02.928][DEBUG][org.mybatis.spring.SqlSessionUtils][http-nio-8088-exec-5] Creating a new SqlSession
[18:18:02.939][DEBUG][org.mybatis.spring.SqlSessionUtils][http-nio-8088-exec-5] SqlSession [org.apache.ibatis.session.defaults.DefaultSqlSession@7eaa1158] was not registered for synchronization because synchronization is not active

过了约4分钟才连接成功，接口返回是正确的

[18:21:59.030][DEBUG][o.m.s.t.SpringManagedTransaction][http-nio-8088-exec-5] JDBC Connection [jdbc:mysql://192.168.0.99:3306/mmall_learning?characterEncoding=utf-8&serverTimezone=UTC&useSSL=false, UserName=root@192.168.0.102, MySQL Connector/J] will not be managed by Spring

后续接口调用就没问题了。请问有其他同学有这个情况吗？
