[SPRING] 중첩 예외가 redis.clients.jedis.exceptions.JedisConnectionException : 풀에서 리소스를 가져올 수 없습니다.

중첩 예외가 redis.clients.jedis.exceptions.JedisConnectionException : 풀에서 리소스를 가져올 수 없습니다.

나는 이미 Jedis와 같은 많은 링크를 통해 갔다. jedis 연결을 얻을 수 없다 : 풀에서 리소스를 얻을 수없고 Jedis 연결을 얻을 수 없다. 풀에서 리소스를 가져올 수 없지만 여전히 아래 오류가 발생했습니다.

Spring Batch에서 Spring Data Redis를 사용하고 mysql에서 데이터를 읽고 redis DB에 쓰고 있습니다. 몇 가지 연결 오류가있는 것 같습니다.

아래 오류를 참조하십시오.

아래의 간단한 구성을 사용하고 있습니다.

해결법

1. ==============================

   1.내가 대답을 게시했습니다 : Redis 10.XX.XX.28에 연결할 수 없습니다 : 6379 : 알 수없는 오류 - 스프링 배치 또는 Windows 컴퓨터에서 액세스하는 동안.

   내가 대답을 게시했습니다 : Redis 10.XX.XX.28에 연결할 수 없습니다 : 6379 : 알 수없는 오류 - 스프링 배치 또는 Windows 컴퓨터에서 액세스하는 동안.

   솔루션은 나를 위해 잘 작동합니다. 그것은 단지 config 변경 사항입니다.

2. ==============================

   2.Azure Redis Cache 구성에서 'SSL을 통한 액세스 만 허용'이 활성화 된 경우 (예 : 포트 번호 6380에 SSL을 사용하고 비 SSL 포트 번호를 6379로 비활성화 한 경우) spring.redis.ssl = true 속성을 다음과 같이 설정하십시오. 귀하의 프로젝트.
