java - Docker 编写 Redis 和 Spring boot 应用程序 : java.net.ConnectException : Connection refused (Connection refused)",

Question

我正在另一个容器中使用 Dockerize spring boot 应用程序和 redis。

我使用 docker compose 在同一网络中运行两个容器，这是我的 docker-compose.yml:

version: '3'
services:
  app:
    image: shortenurl
    links:
      - redis
    ports:
      - 8080:8080
    networks:
      - redis-net
    depends_on:
      - redis

  redis:
    image: redis
    command: ["redis-server", "--appendonly", "yes"]
    hostname: redis
    ports:
      - 6379:6379
    networks:
      - redis-net
    volumes:
      - redis-data:/data

networks:
  redis-net:

volumes:
  redis-data:

这是我的 application.yml 文件:

spring:
  application:
    name: shortenurl
  redis:
    host: localhost
    port: 6379

我也尝试过使用 redis hots = redis 但结果是相同的。

我的问题是，即使容器位于同一网络中，我也会收到此 java.net.ConnectException:连接被拒绝(连接被拒绝)。

我使用 jedis 作为 redis 客户端。问题出在下一个方法中:

这是我的日志:

有什么想法吗？

谢谢!

您需要连接到 Jedis 客户端中的 redis 主机和 Spring Boot 应用程序的 application.yaml

Set<HostAndPort> jedisClusterNodes = new HashSet<HostAndPort>();

jedisClusterNodes.add(new HostAndPort("redis", 6379));
