springboot集成redis报错-ClassNotFoundException: org.apache.commons.pool2.impl.GenericObjectPoolConfig
当使用Springboot 2.0以上版本集成redis的时候遇到报错信息如下：
Application run failed

看提示信息是GenericObjectPoolConfig类无法找到。

https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-2.0-Migration-Guide#redis
特别介绍下在2.x版本中，默认是使用lettuce；1.x版本的时候，默认使用的就是Jedis；关于两个的区别：
Jedis和Lettuce都是Redis Client
Jedis 是直连模式，在多个线程间共享一个 Jedis 实例时是线程不安全的。
如果想要在多线程环境下使用 Jedis，需要使用连接池。
每个线程都去拿Jedis 实例，当连接数量增多时，物理连接成本就较高了。
Lettuce 是基于 netty 的，netty 是一个多线程、事件驱动的 I/O 框架，连接实例可以在多个线程间共享，通过异步的方式可以让我们更好的利用系统资源，而不用浪费线程等待网络或磁盘I/O。
可以在pom文件加上依赖：
<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
<version>2.6.2</version>
</dependency>
或者：
<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-pool2</artifactId>
<version>2.6.2</version>
</dependency>
