Main problem stack: sqlsession [org. Apache. Ibatis. Session. Defaults DefaultSqlSession@7e35f105 ]Was not registered for synchronization because synchronization is not active
scenario: spring boot + mybatis
reason: some mybatis do not output detailed stack information, such as the use of @ param parameter and the mapping of corresponding SQL variables, If you don’t manually try catch, you won’t see the problem or error.
solution: just try catch yourself and solve it according to the stack information
