How to solve the sql execution timeout of springboot configuration mybatis

When some SQL is blocked due to unknown reasons, in order not to affect the running of the background service, we want to increase the execution time limit for the SQL and throw an exception after the timeout to ensure that the background thread will not be blocked due to SQL congestion.

1. Yml global configuration

Single data source is OK, but it will be invalid when using multiple data sources

2.Java configuration class configuration

A timeout exception was successfully thrown.
