I used spring boot data redis to connect to the redis cluster, using version 2.1.3 The configuration is as follows:
@Bean
@Primary
public RedisConnectionFactory myLettuceConnectionFactory(GenericObjectPoolConfig poolConfig) {
RedisClusterConfiguration redisClusterConfiguration = new RedisClusterConfiguration();
final List<String> nodeList = redisProperties.getCluster().getNodes();
Set<RedisNode> nodes = new HashSet<RedisNode>();
for (String ipPort : nodeList) {
String[] ipAndPort = ipPort.split(":");
nodes.add(new RedisNode(ipAndPort[0].trim(), Integer.valueOf(ipAndPort[1])));
}
redisClusterConfiguration.setPassword(RedisPassword.of(redisProperties.getPassword()));
redisClusterConfiguration.setClusterNodes(nodes);
redisClusterConfiguration.setMaxRedirects(redisProperties.getCluster().getMaxRedirects());
LettuceClientConfiguration clientConfig = LettucePoolingClientConfiguration.builder()
.commandTimeout(redisProperties.getTimeout())
.poolConfig(poolConfig)
.build();
RedisClusterClient clusterClient ;
LettuceConnectionFactory factory = new LettuceConnectionFactory(redisClusterConfiguration,clientConfig);
return factory;
}
However, during the operation, a WARN exception message will always be received as follows:
Well, this seems to be a problem with lettuce, How to map remote host & port to localhost using Lettuce,but I don't know how to use it in spring boot data redis. Any solution is welcome, thank you
I've got the answer, so let's define a ClinentRourse like this:
MappingSocketAddressResolver resolver = MappingSocketAddressResolver.create(DnsResolvers.UNRESOLVED ,
hostAndPort -> {
if(hostAndPort.getHostText().startsWith("172.31")){
return HostAndPort.of(ipStr, hostAndPort.getPort());
}
return hostAndPort;
});
ClientResources clientResources = ClientResources.builder()
.socketAddressResolver(resolver)
.build();
Then through LettuceClientConfiguration.clientResources method set in, the normal work of the lettuce.
