UnknownHostException: failed to resolve 'my-redis-host' after 6 queries after switching from Jedis to Redisson

问题

切换从Jedis到Redisson后，我遇到了一个类似的问题：

我尝试了我提到的问题的评论中的所有解决方案和解决方法，但我仍然遇到以下错误：

[java] 20:46:08.537 ERROR [main] o.s.web.context.ContextLoader (ContextLoader.java:313): Context initialization failed org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'MyRedissonConnectionFactory': Invocation of init method failed; nested exception is java.net.UnknownHostException: failed to resolve 'my-redis-host' after 6 queries
...
[java] Caused by: java.net.UnknownHostException: failed to resolve 'my-redis-host' after 6 queries

[java] 20:46:08.606 WARN [main] o.e.jetty.webapp.WebAppContext (WebAppContext.java:554): Failed startup of context o.e.j.w.WebAppContext@19f1f330{/,} org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'myRedissonConnectionFactory': Invocation of init method failed; nested exception is java.net.UnknownHostException: failed to resolve 'my-redis-host' after 6 queries
...
[java] Caused by: java.net.UnknownHostException: failed to resolve 'my-redis-host' after 6 queries
...

我的配置如下：

String host = "my-redis-host";
int port = 6379;
Config config = new Config();
config.useSingleServer()
      .setAddress(String.format("redis://%s:%s", host, port))
      .setPassword("password");

RedissonClient redissonClient = Redisson.create(config);
return new RedissonConnectionFactory(redissonClient);

在docker-compose文件中的服务定义如下：

my-redis-host:
   image: 'bitnami/redis:latest'
   hostname: redis
   container_name: contaner_my-redis-host
   environment:
     - REDIS_PASSWORD=password
   ports:
     - '6379:6379'

版本：

compile group: 'org.redisson', name: 'redisson-spring-data-21', version: '3.12.0'
compile group: 'io.netty', name: 'netty-common', version: '4.1.47.Final'

我做错了什么？如何修复这个问题？

After switching from Jedis to Redisson I have an issue which looks similar

I tried all solutions and workarounds from comments of issues I mentioned but I still experience

my config looks like:

int port = 6379;
Config config = new Config();
config.useSingleServer()
.setAddress(String.format("redis://%s:%s", host, port))
.setPassword("password");
RedissonClient redissonClient = Redisson.create(config);
return new RedissonConnectionFactory(redissonClient);

service definition in docker-compose file:

my-redis-host:
image: 'bitnami/redis:latest'
hostname: redis
container_name: contaner_my-redis-host
environment:
- REDIS_PASSWORD=password
ports:
- '6379:6379'

versions:

compile group: 'org.redisson', name: 'redisson-spring-data-21', version: '3.12.0'
compile group: 'io.netty', name: 'netty-common', version: '4.1.47.Final'

What do I wrong ? How to fix it ?

答案1

得分: 1

确保您的本地 DNS 正确解析 my-redis-host。

英文:

Make sure your local dns resolves my-redis-host correctly
