使用spring+Mybatis報錯org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.builder.BuilderException: Error invoking SqlProvider method (tk.mybatis.mapper.provider.base.BaseSelectProvider.dynamicSQL). Cause: java.lang.InstantiationException: tk.mybatis.mapper.provider.base.BaseSelectProvider
具体如下：
SqlSession [org.apache.ibatis.session.defaults.DefaultSqlSession@1e5f4cdb] was not registered for synchronization because synchronization is not active
Closing non transactional SqlSession [org.apache.ibatis.session.defaults.DefaultSqlSession@1e5f4cdb]
