【redis实战篇】第一天

摘要：

主要是完成点评项目的搭建，以及aplication.yaml文件的填写修改，主要包括数据库连接，redis连接配置

1，aplication.yaml文件

如果是较新版本jdk或者springboot依赖，yaml文件会提示redis的写法过时，所以需要修改一下：

spring: 
  data:
    redis:
      host: 192.168.xxx.xxx
      port: 6379
      password: xxxx
      lettuce:
        pool:
          max-active: 10
          max-idle: 10
          min-idle: 1
          time-between-eviction-runs: 10s
      database: 1 #默认库为0，自行选择

2，修改pom文件，添加了javax的annotation和servlet的api

点评项目默认的jdk(1.8)和springboot(2.x.x)版本较老，我这里就jdk21进行了更新，主要是springboot依赖，mybatisplus依赖（再次强调springboot与mybatisplus版本一定要匹配！！！）

如果还是不清楚自己的版本问题可以参考springboot和mybatisplus的版本匹配与整合问题：Invalid bean definition with name ‘xxxMapper‘ defined in flle解决方法_invalid bean defintion with name trunipmapper defi-优快云博客
