How to use
- What is commons-pool.jar?
Answer: java database connection pool package
- My database connection pool uses the classes provided by spring. Why do I need to import this package?
That depends on which link method you use.
Some packages in spring also depend on other packages.
For example: DBCP class package commons-dbcp.jar. DBCP is a database connection pool that relies on the commons-pool object pool mechanism, so commons-pool.jar must also be included in the class path.
