java - Springboot2使用StringRedisTemplate无法连接docker中的redis集群
问题描述
我在 aws ec2 的 docker 中设置了 redis-cluster。他们使用 docker swarm 网络。ip 是从 10.0.0.6:6379 到 10.0.0.11:6379 并映射到 ec2 静态地址（公共地址：5001 到公共地址：5006） 我可以使用 TablePlus 之类的客户端工具使用公共地址成功访问它们. 但是当我使用spring boot（2.1.1版）和StringRedisTemplate在redis中设置值时，（配置文件是
spring.redis.database=0
spring.redis.password=xxxxxx
spring.redis.cluster.nodes=public address:5001,public address:5002,public address:5003,public address:5004,public address:5005,public address:5006
spring.redis.timeout=5000
pom是
<!-- redis -->

看起来它直接访问 docker swarm net 中的 IP 地址，而不是暴露的公共 IP 地址。我花了很长时间尝试找到解决方案，但仍然无法解决此问题。谁能帮助弄清楚如何解决这个问题？先感谢您。
