沒有Sentinel連接，無法啟動帶有Sping Data Redis的Spring Boot

Question

這是我的第一個問題，請原諒我說問題的方式是否仍然需要改進

我目前正在開發一個Spring Boot Web應用程序，該應用程序使用Redis作為緩存來防止對外部API的過多調用。 從這個意義上講，Spring實際上很好，但不是必需的。

該項目的結構如下

1.）包含DAO類的持久性模塊，該類可編譯spring-data-redis項目並使用帶有@Autowired批注的RedisTemplate

示例RedisDao類（由於私有代碼原因，我沒有使用確切的實現）：

@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構建該項目，以生成要由主項目導入的jar文件

2.）然后，主項目編譯持久性項目，然后在該主項目中設置配置

@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;
   }
}

問題是； 當Sentinel不可用或Sentinel連接錯誤時。 Spring Boot應用程序無法啟動

我嘗試將@Lazy批注添加到所有bean和配置文件，包括持久性模塊中的批注和配置文件，但仍無法正常工作。

我注意到的是，如果JedisConnectionFactory在啟動期間無法檢測到任何Sentinel，則會自動引發異常。

我是否可以知道有什么方法可以阻止Spring Boot在啟動過程中嘗試連接到Sentinel？

非常感謝你

編輯這是錯誤代碼。 至於JedisConnectionFactory Bean； 我讓spring-data-redis自動配置為我處理它，所以我只在我的application.yml文件中設置了所需的屬性

spring.redis:
  pool:
    max-idle: 10
    min-idle: 5
  sentinel:
    master: redis-cluster
    nodes: sentinelhost1:port1,sentinelhost2:port2,sentinelhost3:port3

錯誤

Answer 1

您看到的異常來自JedisConnectionFactory.afterPropertiesSet() 。 您需要將所有與Redis相關的bean都設置為@Lazy ，以及連接工廠。

您將需要聲明自己的JedisConnectionFactory bean。 或者，嘗試使用Lettuce驅動程序，因為Lettuce嘗試相當懶惰地解析Redis服務器。
