Question

我使用springboot和redis构建REST api。使用提供的@Autowired StringRedisTemplate，我可以轻松连接到我的本地redis。但是在生产中我们使用redis池，所以在application.properties文件中我指定了redis池：

spring.redis.sentinel.master=mymaster,mymaster_02
spring.redis.sentinel.nodes=mel-01:26379,mel-02:26379,mel-03:26379

java代码：

 @Autowired
    private RedisTemplate<String, String> redis;

然后当我运行mvn spring-boot：run时，它失败了：

Caused by: java.lang.NullPointerException
    at redis.clients.jedis.JedisSentinelPool.toHostAndPort(JedisSentinelPool.java:159)
    at redis.clients.jedis.JedisSentinelPool.initSentinels(JedisSentinelPool.java:122)
    at redis.clients.jedis.JedisSentinelPool.<init>(JedisSentinelPool.java:73)

    at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1570)

更新：挖掘更多代码并发现springboot无法处理多个主人：

spring.redis.sentinel.master=mymaster,mymaster_02

我们的redis群集是分片的，总共4个节点，数据在节点1,2和节点3之间分割.4。节点2是节点1的从属节点，节点4是节点3的从属节点。在我们的例子中，spring boot工作与redis一点都没？谢谢！

springboot连接到redis池
