一、导入Maven依赖

<!-- redisson-springboot -->
      <dependency>
          <groupId>org.redisson</groupId>
          <artifactId>redisson-spring-boot-starter</artifactId>
          <version>3.11.4</version>
          <exclusions>
              <exclusion>
                  <groupId>org.springframework.boot</groupId>
                  <artifactId>spring-boot-starter-web</artifactId>
              </exclusion>
              <exclusion>
                  <groupId>org.springframework.boot</groupId>
                  <artifactId>spring-boot-starter-webflux</artifactId>
              </exclusion>
          </exclusions>
      </dependency>

二、核心配置文件

redis:
   cluster:
     nodes: "192.168.52.1:7000,192.168.52.1:7001,192.168.52.1:7002,192.168.52.1:7003,192.168.52.1:7004,192.168.52.1:7005"
   password: 123456
   lettuce:
     pool:
       max-active: 1500
       max-wait: 5000
       max-idle: 500
       min-idle: 100
       shutdown-timeout: 1000
   timeout: 60000

三、核心代码配置

RedisConfigProperties.java

import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;
import java.util.List;
@Component
@ConfigurationProperties(prefix = "spring.redis")
public class RedisConfigProperties {
    private String password;
    private cluster cluster;

    public static class cluster {
        private List<String> nodes;

        public List<String> getNodes() {
            return nodes;
        }

        public void setNodes(List<String> nodes) {
            this.nodes = nodes;
        }
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public RedisConfigProperties.cluster getCluster() {
        return cluster;
    }

    public void setCluster(RedisConfigProperties.cluster cluster) {
        this.cluster = cluster;
    }
}

RedissonConfig.java

import org.redisson.Redisson;
import org.redisson.config.ClusterServersConfig;
import org.redisson.config.Config;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import java.util.ArrayList;
import java.util.List;
@Configuration
public class RedissonConfig {
    @Autowired
    private RedisConfigProperties redisConfigProperties;

    //添加redisson的bean
    @Bean
    public Redisson redisson() {
        //redisson版本是3.5，集群的ip前面要加上“redis://”，不然会报错，3.2版本可不加
        List<String> clusterNodes = new ArrayList<>();
        for (int i = 0; i < redisConfigProperties.getCluster().getNodes().size(); i++) {
            clusterNodes.add("redis://" + redisConfigProperties.getCluster().getNodes().get(i));
        }
        Config config = new Config();
        ClusterServersConfig clusterServersConfig = config.useClusterServers()
                .addNodeAddress(clusterNodes.toArray(new String[clusterNodes.size()]));
        clusterServersConfig.setPassword(redisConfigProperties.getPassword());//设置密码
        return (Redisson) Redisson.create(config);
    }
}

四、启动项目，只要不报错就表示配置集群成功，同时启动过程中也会显示连接的各个redis
