详解SpringBoot Redis自适应配置(Cluster Standalone Sentinel)

这篇文章主要介绍了详解SpringBoot Redis自适应配置(Cluster Standalone Sentinel),文中通过示例代码介绍的非常详细,对大家的学习或者工作具有一定的参考学习价值,需要的朋友们下面随着小编来一起学习学习吧

核心代码段

提供一个JedisConnectionFactory  根据配置来判断 单点 集群 还是哨兵

 @Bean @ConditionalOnMissingBean public JedisConnectionFactory jedisConnectionFactory() { JedisConnectionFactory factory = null; String[] split = node.split(","); Set nodes = new LinkedHashSet<>(); for (int i = 0; i  { redisClusterConfiguration.addClusterNode(new RedisNode(n.getHost(), n.getPort())); }); if (!StringUtils.isEmpty(password)) { redisClusterConfiguration.setPassword(RedisPassword.of(password)); } redisClusterConfiguration.setMaxRedirects(maxRedirect); factory = new JedisConnectionFactory(redisClusterConfiguration, jedisClientConfiguration); } return factory; }

pom依赖

配置文件

1.yml配置

1.1支持 Cluster模式 集群

  • node有多个redis的地址,以逗号分隔
  • 如果redis没有密码直接去掉配置就可以了 yml配置
 spring: redis: node: 127.0.0.1:1001,127.0.0.1:1002,127.0.0.1:1003 password: 123456 

properties配置

 spring.redis.node=127.0.0.1:1001,127.0.0.1:1002,127.0.0.1:1003 spring.redis.password=123456 

1.2支持 Standalone模式 单点

node里只有一个redis地址的时候,会自动变成单点模式 yml配置

 spring: redis: node: 127.0.0.1:1001 password: 123456 

properties配置

 spring.redis.node=127.0.0.1:1001 spring.redis.password=123456 

1.3支持 Sentinel模式 哨兵

当配置上sentinel以后就变成了哨兵模式 多个哨兵可以以逗号分割 yml配置

 spring: redis: node: 127.0.0.1:1001 sentinel:127.0.0.1:1002,127.0.0.1:1003 password: 123456 

properties配置

 spring.redis.node=127.0.0.1:1001 spring.redis.sentinel:127.0.0.1:1002,127.0.0.1:1003 spring.redis.password=123456 

1.4覆盖默认配置

如果没有配置这些信息,就会走默认配置 也可以在properties或者yml覆盖默认配置

 #最大连接数, 默认值8个 spring.redis.jedis.pool.max-total=8 #最大空闲连接数, 默认8个 spring.redis.jedis.pool.max-idle=8 #最小空闲连接数, 默认0 spring.redis.jedis.pool.min-idle=0 #获取连接时的最大等待毫秒数,如果超时就抛异常, 小于零:阻塞不确定的时间, 默认-1 spring.redis.jedis.pool.max-wait=-1 #对拿到的connection进行validateObject校验 spring.redis.jedis.pool.test-on-borrow=true #集群时最大重定向个数默认5 spring.redis.jedis.factory.max-redirects=5 

使用 

代码使用

 @Autowired private RedisTemplate redisTemplate;
