Spring Quartz 持久化解决方案
Quartz是实现了序列化接口的，包括接口，所以可以使用标准方式序列化到数据库。
而Spring2.5.6在集成Quartz时却未能考虑持久化问题。
Spring对JobDetail进行了封装，却未实现序列化接口，所以持久化的时候会产生NotSerializable问题，这也是网上一直在那边叫嚣为什么不能持久化到数据库问题，哥今天看了下Spring源码，发现Spring对Quartz持久化的问题.
1. 不知道Spring未来会不会对持久化的支持，不过我们可以有如下解决方案，比如改写
Spring的代码，实现序列化接口.
2. 不使用Spring的Fatory,自己实现任务的初始化.
既然Spring不支持持久化，那么持久化任务还是自己编写实现吧，否则每次都需要打包发布，麻烦，自己编写的类与Quartz完全兼容.
注意:为什么Spring不支持外配置任务，可能也是考虑到这方面问题所以才不提供这些任务的执行化支持.[配置文件配置与数据库配置重复]
直接使用Quartz是支持序列化功能，比如直接使用页面配置Quartz界面，设置任务执行时间等属性。
通过配置实现的是不应该初始化到数据库，否则直接在数据库中配置了。不过也是可以配置的，通过改写JobDetailBean.代码如下:
