Spring 如果没有 Sentinel 连接，则无法使用 Spring Data 启动 Redis
Spring Boot with Sping Data Redis cannot start without Sentinel connections
这是我的第一个问题，如果我对问题的表述方式仍需要改进，请原谅我
我目前正在开发一个 Spring 引导 Web 应用程序，它使用 Redis 作为缓存来防止对外部 API 的过度调用。从这个意义上说，Spring 其实很好，但不是必需品。
项目结构如下
1.) 包含 DAO classes 的持久化模块编译 spring-data-redis 项目并使用带有 @Autowired 注释
的 RedisTemplate
RedisDao 示例class（由于私有代码原因，我没有使用确切的实现）：
@Autowired
private RedisTemplate redisTemplate
public AuthInfoDto createAuthInfo(Integer memberId, Integer expiry) {
//Some method to generate key
String key = createAuthKey(memberId)
redisTemplate.opsForValue().set(key, memberId)
}
然后使用 gradle clean install 构建此项目以生成要由主项目导入的 jar 文件
2.)主工程然后编译持久化工程，我在这个主工程中设置配置
@Configuration
@Lazy
public class RedisConfigure {
@Bean
@Lazy
public RedisTemplate<String, Integer> redisTemplate(JedisConnectionFactory jedisConnectionFactory) {
RedisTemplate<String, Integer> redisTemplate = new RedisTemplate<>();
redisTemplate.setConnectionFactory(jedisConnectionFactory)
redisTemplate.setKeySerializer(new StringRedisSerializer());
redisTemplate.setValueSerializer(new GenericJackson2JsonRedisSerializer());
return redisTemplate;
}
}
问题在于；当 Sentinel 不可用或 Sentinel 出现连接错误时。 Spring 引导应用程序无法启动
我已尝试向所有 bean 和配置文件添加 @Lazy 注释，包括持久性模块中的注释，但它仍然无法正常工作。
我注意到，如果 JedisConnectionFactory 在启动期间无法检测到任何 Sentinel，它会自动抛出异常。
请问有什么方法可以防止 spring 引导程序在启动期间尝试连接到 Sentinel？
非常感谢
编辑
这是错误代码。至于 JedisConnectionFactory Bean；我让 spring-data-redis 自动配置为我处理它，所以我只需在我的 application.yml 文件
中设置所需的属性
spring.redis:
pool:
max-idle: 10
min-idle: 5
sentinel:
master: redis-cluster
nodes: sentinelhost1:port1,sentinelhost2:port2,sentinelhost3:port3

您看到的异常来自 JedisConnectionFactory.afterPropertiesSet()。您需要将所有与 Redis 相关的 bean 设置为 @Lazy，连接工厂也是如此。
您需要声明自己的 JedisConnectionFactory bean。或者，尝试使用 Lettuce 驱动程序，因为 Lettuce 尝试相当懒惰地解析 Redis 服务器。
