spring boot集成redisTemplate redis集群-極簡版（非哨兵）

    首先自己平台組搭建好redis集群~給一堆ip 三主三從

1.導包

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>

<dependency>
    <groupId>redis.clients</groupId>
    <artifactId>jedis</artifactId>
    <version>2.9.0</version>
</dependency>

2.配置yml文件 

redis:
  open: true  # 是否開啟redis緩存  true開啟   false關閉
  database: 0
  host: **.***.**.***:6379,***.**.***.**:6380,***.***.***.***:6379l略
  password: *****  # 密碼（默認為空）
  timeout: 6000  # 連接超時時長（毫秒）
  jedis:
    pool:
      max-active: 1000  # 連接池最大連接數（使用負值表示沒有限制）
      max-wait: -1      # 連接池最大阻塞等待時間（使用負值表示沒有限制）
      max-idle: 10      # 連接池中的最大空閑連接
      min-idle: 5       # 連接池中的最小空閑連接
3.配置config

package com.huatai.server.config;

import org.apache.commons.lang.StringUtils;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.autoconfigure.condition.ConditionalOnClass;

import org.springframework.data.redis.connection.jedis.JedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.core.StringRedisTemplate;
import redis.clients.jedis.JedisCluster;
import redis.clients.jedis.JedisPoolConfig;

import java.util.HashSet;
import java.util.Set;

@Configuration
@ConditionalOnClass({JedisCluster.class})
public class RedisAutoConfiguration {
    @Value("${spring.redis.host}")
    private String host;
    @Value("${spring.redis.password}")
    private String password;
    @Value("${spring.redis.timeout}")
    private int connectionTimeout;
  /*  @Value("${redis.so_timeout:2000}")
    private int soTimeout;
    @Value("${redis.max_attempts:10}")
    private int maxAttempts;*/
    @Value("${spring.redis.jedis.pool.max-active}")
    private int maxTotal;
    @Value("${spring.redis.jedis.pool.min-idle}")
    private int minIdle;
    @Value("${spring.redis.jedis.pool.max-idle}")
    private int maxIdle;
    @Value("${spring.redis.jedis.pool.max-wait}")
    private int maxWaitMillis;

    @Bean(name = "myRedisClusterConfiguration")
    public RedisClusterConfiguration jedisCluster(){
        RedisClusterConfiguration redisClusterConfiguration = new RedisClusterConfiguration();
        String [] hosts = host.split(",");
        Set<RedisNode> nodeList = new HashSet<RedisNode>();
        for (String hostAndPort : hosts){
            String [] hostOrPort = hostAndPort.split(":");
            nodeList.add(new RedisNode(hostOrPort[0],Integer.parseInt(hostOrPort[1])));
        }
        redisClusterConfiguration.setClusterNodes(nodeList);
        redisClusterConfiguration.setMaxRedirects();
        return redisClusterConfiguration;
    }

    @Bean(name = "myJedisPoolConfig")
    public JedisPoolConfig jedisPoolConfig(){
        JedisPoolConfig poolConfig = new JedisPoolConfig();
        poolConfig.setMaxIdle(this.maxIdle);
        poolConfig.setMinIdle(this.minIdle);
        poolConfig.setTestOnCreate(true);
        poolConfig.setTestOnBorrow(true);
        poolConfig.setTestOnReturn(true);
        poolConfig.setTestWhileIdle(true);
        return poolConfig;
    }

    @Bean(name = "MyJedisConnectionFactory")
    public JedisConnectionFactory getJedisConnectionFactory(@Qualifier("myRedisClusterConfiguration") RedisClusterConfiguration redisClusterConfiguration,
                                                            @Qualifier("myJedisPoolConfig") JedisPoolConfig jedisPoolConfig){
        JedisConnectionFactory  jedisConnectionFactory  = new JedisConnectionFactory(redisClusterConfiguration, jedisPoolConfig);
        // 判斷密碼是否存在，存在設置值
        checkPasswordIfNull(jedisConnectionFactory);
        return jedisConnectionFactory;
    }



    @Bean(name = "myRedisTemplates")
    public RedisTemplate redisTemplate(@Qualifier("MyJedisConnectionFactory") JedisConnectionFactory jedisConnectionFactory){
        StringRedisTemplate myRedisTemplate = new StringRedisTemplate();
        myRedisTemplate.setConnectionFactory(jedisConnectionFactory);
        return myRedisTemplate;
    }

    private void checkPasswordIfNull(JedisConnectionFactory jedisConnectionFactory){
        if (!StringUtils.isBlank(password)) {
            jedisConnectionFactory.setPassword(password);

        }
    }

}
4.大功告成 驗證結果
注:spring boot 版本 一定要注意 不然會報錯 親測 適用於2.1.4.RELEASE 2.0.2.RELEASE
