spring boot加载第三方jar包的配置文件的方法

  ……省略getter、setter方法…… 
} 

quartz.config.targetObject=taskJob ## 待执行对象的名字 
quartz.config.targetMethod=doJob ## 待执行的方法的名字 
quartz.config.concurrent=false ## 是否并发，如果上一个定时任务还没有执行完，又被触发了，如果配置为false，则需等待上个任务执行完，才触发 
quartz.config.cronExpression=0/5 * * * * ? ## 任务触发表达式 
quartz.config.applicationContextSchedulerContextKey=applicationContextKey ## 通过该key可以获取spring上下文 
quartz.config.waitForJobsToCompleteOnShutdown=true ## 是否等待任务完全执行完后，再销毁线程池
