Spring boot 3.0 cannot connect to Redis

[wangtianruipopo]

本地电脑启动一个springboot3.0服务，再在本地启动一个redis，这样是可以连接的，但是本地服务无法连接到外部的redis，redis配置肯定没有问题，因为我将版本转换到2.7.9就可以连接了

Start a springboot 3.0 service on the local computer, and then start a Redis locally. This allows for connection, but the local service cannot connect to external Redis. There must be no problem with Redis configuration, as I can connect by converting the version to 2.7.9

but the local service cannot connect to external Redis

How does it fail? Please share the log output that's produced.

There must be no problem with Redis configuration, as I can connect by converting the version to 2.7.9

Spring Boot 3.0 has upgraded to new versions of both Jedis and Lettuce. Which one are you using?

@wilkinsona Connecting to Redis on one's own computer is sufficient, but connecting to external Redis, i.e. Redis not on one's own computer, is not sufficient
But spring boot version 2.7.9 can connect normally
3.0 and above failed with this error reported

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>

This is my pom file

Have you updated your Redis configuration properties, as described in the migration guide?

[wangtianruipopo]

spring:
  data:
    redis:
      host: lms-cloud-redis #服务器地址 你服务器或本机地址
      port: 6379 #连接端口
      database: 0 #数据库索引，默认0
      password: 000415 #密码
      jedis:
        pool:
          max-active: 8 #连接池最大连接数(使用负值表示没有限制)
          max-wait: -1 #最大阻塞等待时间(使用负值表示没有限制)
          max-idle: 8 #最大空闲连接数
          min-idle: 0 #最小空闲连接数
      timeout: 5000 #连接超时时间（毫秒）

Is this right? Still reporting the same error

[wilkinsona]

Yes, that looks right.

If you would like us to spend some more time investigating, please spend some time providing a complete yet minimal sample that reproduces the problem. You can share it with us by pushing it to a separate repository on GitHub or by zipping it up and attaching it to this issue.
