我试图启动我的 SpringBoot 应用程序，但未在编译前配置 DataSource。如果我这样做，指示参数，应用程序正常工作，但我想在运行 docker 容器时通过 JAVA_OPTS 参数传递它们。像那样:
docker run --network public --link pg --name tm -e JAVA_OPTS="-Ddatasource.jdbcUrl=jdbc:postgresql://pg:5432/ggal1701 -Ddatasource.user=postgres -Ddatasource.password=postgres" -p 9000:8080 worker
我已经尝试了很多我在 Stackoverflow 上看到的选项，但没有一个对我有用。

## Configuraciones de GRADLE
##
## Below are some of the gradle performance improvement settings that can be used as required, these are not enabled by default
##
## The Gradle daemon aims to improve the startup and execution time of Gradle.
## When set to true the Gradle daemon is to run the build.
## TODO: disable daemon on CI, since builds should be clean and reliable on servers
## un comment the below line to enable the daemon
#org.gradle.daemon=true
## Specifies the JVM arguments used for the daemon process.
## The setting is particularly useful for tweaking memory settings.
## Default value: -Xmx1024m -XX:MaxPermSize=256m
## un comment the below line to override the daemon defaults
#org.gradle.jvmargs=-Xmx1024m -XX:MaxPermSize=256m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8
## When configured, Gradle will run in incubating parallel mode.
## This option should only be used with decoupled projects. More details, visit
## http://www.gradle.org/docs/current/userguide/multi_project_builds.html#sec:decoupled_projects
## un comment the below line to enable parellel mode
#org.gradle.parallel=true
## Enables new incubating mode that makes Gradle selective when configuring projects.
## Only relevant projects are configured which results in faster builds for large multi-projects.
## http://www.gradle.org/docs/current/userguide/multi_project_builds.html#sec:configuration_on_demand
## un comment the below line to enable the selective mode
#org.gradle.configureondemand=true

最佳答案
您有两个选择，都可以正常工作:
首先 是将值作为 JAVA_OPTS 传递，如下所示(您正在通过错误的参数):
docker run \
--network public \
--link pg \
--name tm \
-e JAVA_OPTS= \
"-Dspring.datasource.url=jdbc:postgresql://pg:5432/ggal1701
-Dspring.datasource.username=postgres \
-Dspring.datasource.password=postgres" \
-p 9000:8080 worker
第二个 是将值作为环境变量传递如下(您的错误是没有引号):
docker run \
--network public \
--link pg \
--name tm \
-e DATASOURCE_JDBC_URL="jdbc:postgresql://pg:5432/ggal1701" \
-e DB_USERNAME="postgres" \
-e DB_PASSWORD="postgres" \
-p 9000:8080 worker
请记住在您的配置中指定这些参数以使用第二个选项。在第一个中，您无需直接配置任何内容。
作为 devOps 文化的一部分，我从不建议对设置进行硬编码并选择第二个选项，因为它是为此目的而设计的。他们都必须为你工作，如果你不这样做，你就会犯其他错误。
您所说的 hikariPool 错误只是数据源故障的结果。尝试这两种方式中的一种，在我的专业意见中，选择第二种。
