那些遇到过的问题

我在 docker-compose 中有一个带有 Postgresql 的 Java Spring 启动，org.postgresql.util.PSQLException: Connection to localhost:5432

Fur*_*bal 5 postgresql docker spring-boot docker-compose devops

引起的原因：org.postgresql.util.PSQLException：与 localhost:5432 的连接被拒绝。检查主机名和端口是否正确以及邮局主管是否接受 TCP/IP 连接。

我在创建 docker 镜像时遇到问题。

当我检查 postgres 端口时

postgres   4318 iqbal    8u  IPv4 0xbccc4b164eb6b423      0t0  TCP 127.0.0.1:5432 (LISTEN)

Run Code Online (Sandbox Code Playgroud)

运行docker-compose up -d，等到它启动，然后运行docker ps -a来检查容器是否正在运行或已崩溃，使用docker logs {container name}从给定容器获取标准输出来找出崩溃的原因。

您可能还需要调整 Java 代码，以便它不会尝试连接到 localhost 的 postgresql，而是尝试连接到 postgresqldb:5432。您应该能够使用 $SPRING_DATASOURCE_URL 环境变量来实现此目的。

如果您仍然遇到连接问题，请为我评论您的新错误，我将更新此答案。
