解决SpringBoot环境下Redis哨兵模式连接失败问题，“NOAUTH Authentication required”

io.lettuce.core.RedisCommandException Exception:“NOAUTH Authentication required”

在某行工作，项目上线代码，uat环境无异常，上到pp环境有问题，报redis连接不上；

观察配置，发觉是apollo的配置是哨兵模式，有个哨兵密码。spring2.2.6RELEASE版本问题。于是写了全局配置，读取配置中的sentinel.password

package com.yupi.springbootinit.config;

@Configuration

    // 配置sentinel密码不生效，提示NOAUTH Authentication required。

    @Bean
    public RedisSentinelConfiguration redisSentinelConfiguration(RedisProperties properties , @Value("${spring.redis.sentinel.password}") String sentinelPassword){
        RedisProperties.Sentinel sentinelProperties = properties.getSentinel();

        if (sentinelProperties != null) {
            RedisSentinelConfiguration config = new RedisSentinelConfiguration();
            config.master(sentinelProperties.getMaster());
            config.setSentinels(createSentinels(sentinelProperties));

            if (properties.getPassword() != null){
                config.setPassword(RedisPassword.of(properties.getPassword()));
            }
            if (sentinelPassword != null) {
            config.setSentinelPassword(RedisPassword.of(sentinelPassword));
            }
            config.setDatabase(properties.getDatabase());
            return config;
        }
        return null;
    }
        private List<RedisNode> createSentinels(RedisProperties.Sentinel sentinel) {
            List<RedisNode> nodes = new ArrayList<>();
            for (String node : sentinel.getNodes()) {
                String[] split = StringUtils.split(node, ":");
                Assert.notNull(split,"Must be defined as 'host:port'");
                Assert.state(split.length==2,"Must be defined as 'host:port'");
                nodes.add(new RedisNode(split[0],Integer.parseInt(split[1])));
            }
           return nodes;
        }
