2、问题分析

        这一块的主要原因是redis配置的连接池原因，我们目前配置的连接池如下：

  1. jedis:
  2.       pool:
  3.         max-active: 50
  4.         max-wait: 50
  5.         max-idle: 50
  6.         min-idle: 0

后来通过翻阅资料，查看其底层配置发现，在 Spring Boot 1.x 版本默认使用的是 Jedis ，而在 Spring Boot 2.x 版本默认使用的就是Lettuce。而我们的springboot版本已经使用到了 2.2.5.RELEASE 版本了，所以上述配置，其实是无效的！！！

        那么此时，通过查看源码发现：

watermark,type_d3F5LXplbmhlaQ,shadow_50,text_Q1NETiBA5ZaE6Imv5Yuk5Yqz5YuH5pWi6ICM5Y-I6IGq5piO55qE6ICB5p2o,size_8,color_FFFFFF,t_70,g_se,x_16

         所以，因为配置的最大可用数量是不满足业务的，因此导致了上述的报错！！！

3、问题解决

        加上如下配置即可（具体配置可用数量，请根据业务具体情况使用）：

  1. spring:
  2.   redis:
  3.     lettuce:
  4.       pool:
  5.         max-active: 50
  6.         max-wait: 50
  7.         max-idle: 50
  8.         min-idle: 0
