介绍

这里是小编成长之路的历程，也是小编的学习之路。希望和各位大佬们一起成长！

以下为小编最喜欢的两句话：

要有最朴素的生活和最遥远的梦想，即使明天天寒地冻，山高水远，路远马亡。

一个人为什么要努力？ 我见过最好的答案就是：因为我喜欢的东西都很贵，我想去的地方都很远，我爱的人超完美。因此，小编想说：共勉！

小编今天使用Springboot+redis，将数据添加到redis中发生错误

问题描述：

以下是报错的代码，表示在连接redis的时候报错，找不到redis的配置文件

解决方法：

下面的代码是application.properties的配置 ，小编就犯了一个错误，在spring配置文件中加入redis的时候没有在前面加入spring

# 这个是整合swagger文档的时候，启动出现报错的解决，主要原因是springboot parent版本过高，与swagger不兼容spring.mvc.pathmatch.matching-strategy=ANT_PATH_MATCHERredis.host=localhostredis.port=6379redis.password=123456redis.maxIdle=50redis.maxTotal=100redis.maxWaitMillis=3000redis.testOnBorrow=trueredis.timeout=5000redis.nowDatabase=0

这个时候就更改一下application.properties配置文件

# 这个是整合swagger文档的时候，启动出现报错的解决，主要原因是springboot parent版本过高，与swagger不兼容spring.mvc.pathmatch.matching-strategy=ANT_PATH_MATCHERspring.redis.host=localhostspring.redis.port=6379spring.redis.password=123456spring.redis.maxIdle=50spring.redis.maxTotal=100spring.redis.maxWaitMillis=3000spring.redis.testOnBorrow=truespring.redis.timeout=5000spring.redis.nowDatabase=0

以上就是小编所实践的内容，希望能够帮助到大家，感谢各位大佬的观看！！！
