BeanFactory与FactoryBean的区别

有很多常用的FactoryBean类:

1.org.springframework.scheduling.quartz.SchedulerFactoryBean

2.org.springframework.scheduling.quartz.CronTriggerFactoryBean

3.org.springframework.scheduling.quartz.SimpleTriggerFactoryBean

4.org.springframework.scheduling.quartz.JobDetailFactoryBean

5.org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean

6.org.springframework.beans.factory.config.PropertiesFactoryBean

这些类都实现了org.springframework.beans.factory.FactoryBean<Object>接口、org.springframework.beans.factory.InitializingBean接口(在spring-beans-xxx.jar包中)

创建jedisCluster时，要创建一个JedisClusterFactory工厂类，需实现FactoryBean接口。

BeanFactory接口，全类名是org.springframework.beans.factory.BeanFactory，是访问spring容器的根接口，spring-context-xxx.jar包中的org.springframework.context.ApplicationContext接口是其子接口
