Unable to use external configuration with Quarkus

问题

我在使用Quarkus应用程序时遇到了问题，无法使用外部配置属性。

我想要覆盖数据库属性。项目中的application.properties文件具有开发和测试环境的属性，但没有生产环境的属性。生产环境的值在外部的application.properties文件中。

我阅读了官方指南（https://quarkus.io/guides/config#overriding-properties-at-runtime），并尝试将一个名为config的文件夹与runner-jar文件平行放置一个application.properties文件。但这并没有起作用。而且仅仅通过命令行传递属性也不起作用。

C:.

内部配置：

%dev.quarkus.datasource.jdbc.url=jdbc:postgresql://localhost:5432/postgres
%dev.quarkus.datasource.username=postgres
%dev.quarkus.datasource.password=postgres
%dev.quarkus.datasource.db-kind=postgresql

%test.quarkus.datasource.username=sa

外部配置：

quarkus.datasource.username=postgres
quarkus.datasource.password=postgres
quarkus.datasource.db-kind=postgresql
quarkus.hibernate-orm.database.generation=none

使用java -jar .\0.1.0-SNAPSHOT-runner.jar命令会产生以下错误：

我只找到两个类似的讨论帖子（https://stackoverflow.com/questions/55043399/how-can-i-override-properties-in-quarkus 和 https://github.com/quarkusio/quarkus/issues/1218）。两者都提到了使用config文件夹中的application.properties文件的方法。因为这对我不起作用，我找不到任何新信息，所以我有点迷茫...

我会非常感谢任何帮助！

英文:

I am having trouble to use external configuration properties for my Quarkus application.

I want to override the database properties. The application.properties inside the project has properties for dev and test, not for prod. The values for prod are inside the external application.properties.

I read the official guide (https://quarkus.io/guides/config#overriding-properties-at-runtime) and tried to place an application.properties file in a folder next to the runner-jar called config. That didn't work. But just passing the properties on the command line didn't work either.

I could only find two similar threads (https://stackoverflow.com/questions/55043399/how-can-i-override-properties-in-quarkus and https://github.com/quarkusio/quarkus/issues/1218). Both mention the method with the application.properties in the config folder. Since this does not work for me and I cannot find any new information, I am somewhat lost ...

I would be grateful for any help!

好的，原文已翻译如下：

嗯，事实证明在运行时无法覆盖几个属性。这些属性在官方的所有属性概览中有标注（https://quarkus.io/guides/all-config）。页面顶部有关于这方面的小提示。

quarkus.datasource.db-kind 就是其中之一。所以我所需要做的就是在我的主 application.properties 文件中包含这个属性。在那之后，外部文件就能被找到，我可以使用这些值作为 URL、密码和用户名。

英文:

Ok, so it turns out there are several properties which you can not override at runtime. Those are marked on the offical overview of all properties (https://quarkus.io/guides/all-config). There is a little hint about this at the top of the page.

quarkus.datasource.db-kind is one of those properties. So all I had to do is include this property in my main application.properties. After that the external file was found and I could use those values for url, password, and username.

Max在说quarkus.datasource.db-kind是一个运行时属性时是正确的。

唯一让我成功工作的方式是这样的，这样我就有了：

%dev 
quarkus.datasource.db-kind=postgres

%qa
quarkus.datasource.db-kind=h2

%prod
quarkus.datasource.db-kind=<otherDBKind>

要么使用分析:

gradle/maven quarkusDev -Dquarkus-profile=[dev,qa,prod]

要么，如果你想部署应用并通过java -jar运行它，你必须使用配置文件上下文编译它:

gradle/maven quarkusBuild -Dquarkus-profile=[dev,qa,prod]

为每个配置文件构建一个具有不同db-kind的构建。

英文:

Max is right when he says that quarkus.datasource.db-kind is a runtime property.

The only way I got it to work so that I have

%dev 
quarkus.datasource.db-kind=postgres

%qa
quarkus.datasource.db-kind=h2

%prod
quarkus.datasource.db-kind=&lt;otherDBKind&gt;

is to, either use profiling:

gradle/maven quarkusDev -Dquarkus-profile=[dev,qa,prod]

or, if you want to deploy the application and run it through java -jar, you have to compile it with the profile context

gradle/maven quarkusBuild -Dquarkus-profile=[dev,qa,prod]

a build for each profile with a different db-kind
