spring3. For versions 1.0 and below, use versions below quartz2. OK

spring3. For versions 1.1 and above, the version below quartz2 is OK

This example: using spring 3 1.0 + quartz1. 8.2 OK

Tested: spring 3 1.1+quartz2. 1.0 OK

However, org. Org is required in the above configuration file springframework. scheduling. quartz. Crontriggerfactorybean (the lower version uses crontriggerbean)
