springboot升级到3.2redis配置变化导致连接失败

2023-12-16 13:03:02

想体验一下java的虚拟线程,新建一个springboot项目,使用版本是3.2。其他功能测试还好,当测试到redis功能时,发现连接不上服务器了。经过检查是因为redis配置文件读取配置前缀发生了变化,2.x版本的配置前缀是 spring.redis 到 3.x变为了 spring.data.redis,所以配置文件也要做相应的改变,否则读取配置文件读取不到。
2.x的配置文件:

spring:
  redis:
    host: 192.168.56.101
    port: 6379
    password: 123456
    database: 1
    timeout: 3000
    lettuce:
      pool:
        max-active: 16
        max-idle: 8
        max-wait: -1
        min-idle: 1

3.x的配置文件:

spring:
  data:
    redis:
      host: 192.168.56.101
      port: 6379
      password: 123456
      database: 1
      timeout: 3000
      lettuce:
        pool:
          max-active: 16
          max-idle: 8
          max-wait: -1
          min-idle: 1

如果你刚好测试服务和redis在一个机器上,可能不会出现问题,因为读取不到配置内容默认也会连接到本地的redis服务器。redis配置信息会加载到配置类 org.springframework.boot.autoconfigure.data.redis.RedisProperties 中。
