java - 没有 Sentinel 连接，Spring Boot 和 Spring Data Redis 无法启动

Question

这是我的第一个问题，如果我的问题表达方式还需要改进，请原谅我

我目前正在开发一个 Spring Boot 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 实际上很好，但不是必需的。

项目结构如下

1.) 包含 DAO 类的持久化模块编译 spring-data-redis 项目并使用带有 @Autowired 注解的 RedisTemplate

示例 RedisDao 类(由于私有(private)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)

}

然后用gradle clean install构建这个项目，生成主项目导入的jar文件

2.) 然后主项目编译持久化项目，我在这个主项目中设置配置

@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 Boot应用无法启动

我已尝试将 @Lazy 注释添加到所有 bean 和配置文件，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。

我可以知道是否有任何方法可以防止 spring boot 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

错误

Answer 1

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，以及连接工厂。

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。
