Springboot 2.x 需要 c3p0 吗？

Question

I am migrating a existing Spring application (non Spring boot) to Springboot 2.x. I see there is a c3p0.properties file with following configuration: com.mchange.v2.c3p0.management.ExcludeIdentityToken=true . What does this does exactly? Do I need this if I am using Springboot 2.x? Or do I need to setup something else configuration in my application.properties file?

Thank you for help.

Answer 1

Spring Boot 2.x use HikariCp as a default JDBC connection pool. It is faster then c3p0. You should use Hikari.

You can read about it compared with c2p0:

Hikari vs other CPs

Spring Boot will autoconfig it to you, but you can customize it (for example in application.properties)

For the com.mchange.v2.c3p0.management.ExcludeIdentityToken visit the documentation page's Jmx configuration section
