import org.springframework.data.redis.connection.RedisClusterConfiguration;
import org.springframework.data.redis.connection.RedisNode;
import org.springframework.data.redis.connection.RedisStandaloneConfiguration;
import org.springframework.data.redis.connection.jedis.JedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.core.ValueOperations;

import java.util.Collections;
import java.util.List;
import java.util.Objects;
public class RedisTest {
    public static void main(String[] args) {
        //单机模式
        RedisStandaloneConfiguration rsc = new RedisStandaloneConfiguration();
        rsc.setPort(6379);
        rsc.setPassword("123456");
        rsc.setHostName("192.168.1.1");

        //集群模式
        RedisClusterConfiguration rcc = new RedisClusterConfiguration();
        rcc.setPassword("123456");
        List<RedisNode> nodes = Collections.singletonList(new RedisNode("192.168.1.1", 6379));
        rcc.setClusterNodes(nodes);

        RedisTemplate<String, String> template = new RedisTemplate<>();
        //单机模式
        JedisConnectionFactory fac = new JedisConnectionFactory(rsc);
        //集群模式
        //JedisConnectionFactory fac = new JedisConnectionFactory(rcc);
        fac.afterPropertiesSet();
        template.setConnectionFactory(fac);
        template.setDefaultSerializer(new StringRedisSerializer());
        template.afterPropertiesSet();
        ValueOperations<String, String> op = template.opsForValue();
        final String key = "123_tmp";
        final String value = "abc";
        template.delete(key);
        op.set(key, value);
        assert Objects.equals(op.get(key), value);
    }
}

集群方式运行报错

Exception in thread "main" redis.clients.jedis.exceptions.JedisDataException: ERR This instance has cluster support disabled

解决

1. 在redis.conf下将cluster-enabled改为yes
2. 如果只有一个节点, 改为单机模式
