问题

学习Langchain4j过程中，想用Redisearch作为向量数据库，出现了创建Bean异常：

2025-08-22T10:11:43.389+08:00  WARN 15268 --- [           main] ConfigServletWebServerApplicationContext : Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'commonConfig': Unsatisfied dependency expressed through field 'redisEmbeddingStore': Error creating bean with name 'redisEmbeddingStore' defined in class path resource [dev/langchain4j/community/store/embedding/redis/spring/RedisEmbeddingStoreAutoConfiguration.class]: Failed to instantiate [dev.langchain4j.community.store.embedding.redis.RedisEmbeddingStore]: Factory method 'redisEmbeddingStore' threw exception with message: Invalid rule type

问题分析

redis-search版本和LangChain4j版本不匹配，当换上2.4.9的search版本时，SpringBoot能正确创建Bean注入容器，并实现Redis存储向量。

# 安装redisearch的docker命令
 docker run -d --name redis-vector -p 6379:6379 redislabs/redisearch:2.4.9

总结

需要注意版本兼容性问题
