程序报错：jdbcconnection will not be managed by spring

This error message typically occurs when you are using Spring framework to manage database connections, but the JDBC connection is not being properly managed by Spring.

To resolve this issue, you need to make sure that you are using the correct Spring JDBC templates and that you have properly configured your data source. Here are some steps that you can follow to fix this error:

1. Make sure that you are using the correct Spring JDBC templates. Depending on your project setup, you may need to use either the JdbcTemplate or NamedParameterJdbcTemplate.

2. Ensure that you have properly configured your data source. You can do this by defining a DataSource bean in your Spring configuration file and setting the necessary properties (e.g. URL, username, password, etc.).

3. Make sure that you are using the correct transaction management settings. If you are using Spring's declarative transaction management, make sure that you have properly annotated your service methods with the @Transactional annotation.

4. Check your code for any manual creation or management of JDBC connections. This can interfere with Spring's management of database connections and cause the error message.

By following these steps, you should be able to resolve the "jdbcconnection will not be managed by spring" error and properly manage your database connections using Spring.
