Java 从容器内部连接到PostgreSQL容器时出现问题

我在尝试将docker容器连接到PostgreSQL容器时遇到问题。正在引发以下异常：

org.postgresql.util.PSQLException: The connection attempt failed

我正在通过docker-compose.yml启动容器，它看起来像：

version: "2.1"

services:
    stockprocessor:
        image: stockprocessor
        container_name: stockprocessor
        environment:
            DATABASE_HOST: postgres-db
            DATABASE_PORT: 5432
        depends_on:
        - postgres-db
        ports:
        - 2001:2001

    postgres-db:
        image: postgres:11.1
        container_name: postgres-db
        restart: always
        environment:
            POSTGRES_PASSWORD: password
            POSTGRES_USER: sample
            POSTGRES_DB: sample
        ports:
        - 5432:5432

我的Spring Boot应用程序设置如下：

spring.datasource.platform=postgres
spring.datasource.url=jdbc:postgresql://${DATABASE_HOST:localhost}:${DATABASE_PORT:5432}/sample
spring.datasource.username=sample
spring.datasource.password=password
spring.jpa.hibernate.ddl-auto=create-drop
spring.jpa.properties.hibernate.jdbc.lob.non_contextual_creation=true

我不知道我做错了什么，有人能帮忙吗？谢谢大家!

[[编辑]]

在更彻底地分析stacktrace之后，我注意到

Caused by: java.net.UnknownHostException: postgres-db 

错误，这首先会导致问题。通过从postgres db容器获取IP后

docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' postgres-db

将数据库主机设置为该IP也不起作用

如果您的服务

stockprocessor

在数据库完全初始化之前或在初始化期间启动，则可能会发生这种情况

然后，在启动应用程序之前，您必须确保

postgres db

服务正在接受连接

---

为此，在应用程序容器上运行命令之前，可以使用

wait.sh

script（检查）。或者，您可以在

stockprocessor

服务（）上设置重新启动策略（

restart:on failure

），以自动重新启动服务（直到数据库启动）。

localhost无法工作；它不应该指容器IP吗？用户名和密码不一样。请输入错误的用户名，编辑我的帖子@duffymo：我正在通过docker compose将主机设置为服务名称，在本例中是postgres-db.Hi@norbjd，我尝试了两种解决方案，但遗憾的是没有一种有效。虽然等待脚本根本没有延迟启动，重启策略只是让处理器一次又一次地启动，但我尝试访问postgres db容器——成功了。我想要的数据库已经创建好了，我能够操作表之类的东西，而处理器却一次又一次地重新启动。嗯，我明白了，只是写了这个解决方案，因为90%的问题都是由启动顺序引起的。你有关于你的例外情况的更多信息吗？Stacktrace，是哪行代码导致。。。（编辑您的问题）

连接尝试失败

可能由1000个原因造成！啊，是的，我刚刚添加了整个stacktrace，现在我注意到了这个错误：

由以下原因引起：

-但是localhost也不工作。你能检查一下

/etc/hosts

容器中的

stockprocessor

的内容吗（是

postgres db

内部）？我已将主机输出添加到原始问题中。
