一、安裝Redis叢集

安裝步驟參照網上教程，Mac安裝步驟參照https://github.com/muyl/mac-docker-redis-cluster

二、建立SpringBoot工程

1. 建立Redis配置類

   package com.example.chapterredis.common.config;
   
   import org.apache.commons.pool2.impl.GenericObjectPoolConfig;
   import org.slf4j.Logger;
   import org.slf4j.LoggerFactory;
   import org.springframework.beans.factory.annotation.Value;
   import org.springframework.context.annotation.Bean;
   import org.springframework.context.annotation.Configuration;
   import redis.clients.jedis.HostAndPort;
   import redis.clients.jedis.JedisCluster;
   
   import java.util.HashSet;
   import java.util.Set;
   
   /**
    * @author tony
    */
   @Configuration
   public class RedisConfiguration {
   
       private static final Logger logger = LoggerFactory.getLogger(RedisConfiguration.class);
   
       @Value("${spring.redis.clusterNodes}")
       private String  clusterNodes;
       @Value("${spring.redis.password}")
       private String  auth;
       @Value("${spring.redis.pool.maxActive}")
       private Integer maxTotal;
       @Value("${spring.redis.pool.minIdle}")
       private Integer minIdle;
       @Value("${spring.redis.pool.maxIdle}")
       private Integer maxIdle;
       @Value("${spring.redis.pool.maxWait}")
       private Long    maxWaitMillis;
       @Value("${spring.redis.pool.commandTimeout}")
       private int     commandTimeout;
   
   
       @Bean
       public JedisCluster jedisCluster() {
           String[] serverArray = clusterNodes.split(",");
           Set<HostAndPort> nodes = new HashSet<>();
           for (String ipPort : serverArray) {
               String[] ipPortPair = ipPort.split(":");
               nodes.add(new HostAndPort(ipPortPair[0].trim(), Integer.valueOf(ipPortPair[1].trim())));
           }
   
           if (!nodes.isEmpty()) {
               String password = getAuth(auth);
               logger.info("redis password:{}", password);
               GenericObjectPoolConfig pool = new GenericObjectPoolConfig();
               pool.setMaxTotal(maxTotal);
               pool.setMinIdle(minIdle);
               pool.setMaxIdle(maxIdle);
               pool.setMaxWaitMillis(maxWaitMillis);
               return new JedisCluster(nodes, commandTimeout, commandTimeout, 5, password, pool);
           }
           return null;
       }
   
       private String getAuth(String auth) {
           return "".equals(auth) ? null : auth;
       }
   }
    
   

2. SpringBoot屬性檔案

   spring.redis.clusterNodes=localhost:7000,localhost:7001,localhost:7002,localhost:7003,localhost:7004,localhost:7005
   spring.redis.password=
   spring.redis.pool.maxActive=5
   spring.redis.pool.minIdle=5
   spring.redis.pool.maxIdle=1
   spring.redis.pool.maxWait=3000
   spring.redis.pool.commandTimeout=5000

3. SpringBoot啟動類

   package com.example.chapterredis;
   
   import org.springframework.boot.SpringApplication;
   import org.springframework.boot.autoconfigure.SpringBootApplication;
   
   @SpringBootApplication
   public class ChapterRedisApplication {
   
       public static void main(String[] args) {
           SpringApplication.run(ChapterRedisApplication.class, args);
       }
   }
    
   

4. 測試類

   package com.example.chapterredis;
   
   import org.junit.Test;
   import org.junit.runner.RunWith;
   import org.springframework.beans.factory.annotation.Autowired;
   import org.springframework.boot.test.context.SpringBootTest;
   import org.springframework.test.context.junit4.SpringRunner;
   import redis.clients.jedis.JedisCluster;
   
   @RunWith(SpringRunner.class)
   @SpringBootTest(classes={ChapterRedisApplication.class})
   public class ChapterRedisApplicationTests {
   
       @Autowired
       private JedisCluster jedisCluster;
   
   
       @Test
       public void test2() {
           jedisCluster.set("aaa","123");
           System.out.println(jedisCluster.get("aaa"));
       }
   
   }

比你優秀的人比你還努力，你有什麼資格不去奮鬥
