这是我的第一个问题，所以如果我表达问题的方式仍然需要改进，请原谅我
我目前正在开发一个 Spring Boot Web 应用程序，该应用程序使用 Redis 作为缓存来防止对外部 API 的过度调用。从这个意义上说，春天其实是好东西，但不是必需品。
项目结构如下
1.( 一个包含 DAO 类的持久性模块，用于编译 spring-data-redis 项目并使用带有@Autowired注释的 RedisTemplate
示例 RedisDao 类(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 干净安装构建此项目，以生成要由主项目导入的 jar 文件
2.( 然后主项目编译持久性项目，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;
}
}
问题是;当Sentinel不可用或与Sentinel的连接错误时。Spring 引导应用程序无法启动
我尝试向所有 bean 和配置文件添加@Lazy注释，包括持久性模块中的注释，但它仍然不起作用。
我注意到的是，如果在启动过程中无法检测到任何哨兵，JedisConnectionFactory 会自动抛出异常。
我可以知道是否有任何方法可以防止 Spring 启动在启动期间尝试连接到 Sentinel？
谢谢
编辑这是错误代码。至于绝地连接工厂豆;我让 spring-data-redis 自动配置为我处理它，所以我只是在我的 application.yml 文件中设置了所需的属性
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，以及连接工厂。
您需要声明自己的JedisConnectionFactory豆。或者，尝试使用生菜驱动程序，因为生菜尝试相当懒惰地解析 Redis 服务器。
