listener配置可以看源碼，主要的上面的參數配置為<context-param>,再加一個<listener>.

上面提到了quartz.properties,這是自行指定的，Quartz提供了一個默認的配置文件，可以滿足基本的j2se應用，如果在web應用中，我們想把job,trigger配置都寫到文件中，就需要自己來寫，并指定在初始化時加載我們自己的quratz.properties，位置放在classes下。

org.quartz.plugin.jobInitializer.overWriteExistingJobs = true
org.quartz.plugin.jobInitializer.failOnFileNotFound = true
org.quartz.plugin.jobInitializer.scanInterval = 10

quartz要使用插件來加載自己的xml配置文件，上邊我們指定了在初始化時加載classes/scheduler/quartz_jobs.xml，默認的是加載classes/quartz_jobs.xml文件。

quartz_jobs.xml文件：
<?xml version='1.0' encoding='utf-8'?>
