This article mainly introduces how to set SpringBoot+Quartz+ database storage, the article is very detailed, has a certain reference value, interested friends must read it!

The database we need

The default connection pool for Quartz is c3p0. If your connection pool is different, you need to replace its configuration file directly. For example, if the connection pool I use is druid, you need to change the configuration yourself (if you use c3p0, you don't need to change it) tool class utils MyJobFactory
