Java连接redis报错timed out问题解决

现象

• 之前写了一篇文章：Spring redis使用报错Read timed out排查解决，解决超时问题
• 后面发现解决的不彻底，仍有报错
• 详细查看了下源码，发现不同版本里，参数名不一样，之前的参数设置，并没有在新版本里生效

解决

• 原有配置

spring:
  redis:
    host: 192.168.1.50
    port: 6379
    password:
    database: 0
    jedis:
      pool:
        min-idle: 10
        max-idle: 400
        max-wait: 30000
        max-active: 200

• 少了对于redis客户端连接维护的超时时间设置，默认是2s
• 当大并发量来临，阻塞超过2s时，就会报错
• 新的配置（时间可以写毫秒，也可以带单位）

spring:
  redis:
    host: 192.168.1.50
    port: 6379
    password:
    database: 0
    timeout: 30s # 读写超时
    connect-timeout: 60s #连接超时
    jedis:
      pool:
        min-idle: 8 # 最小空闲连接
        max-idle: 200 # 最大空闲连接
        max-wait: 30s # 连接池最大阻塞等待时间（使用负值表示没有限制）
        max-active: 256 # 连接池最大连接数（使用负值表示没有限制）
