Question

我有一个必须在生产中部署的Spring应用程序。不幸的是，我无法打开产品配置文件。我有一个application-dev.yml和application-prod.yml文件以及application.yml。我的application.yml如下：

# ===================================================================
# Spring Boot configuration.
#
# This configuration will be overridden by the Spring profile you use,
# for example application-dev.yml if you use the "dev" profile.

因此您可以看到我将spring.profiles.default和spring.pofiles.active设置为prod。我还尝试使用maven和选项-Dspring.profiles.active=prod来构建应用程序，但是尽管如此，每次运行战争时，它都会显示The following profiles are active: swagger,dev。

任何人都有一个想法，为什么未加载产品概要文件？预先感谢。

Answer 1

我已经在spring-boot 2.1.4上验证了以下配置：

application.yaml：

spring:
 profiles:
   active: dev

application-dev.yaml：

sample:
  value: development

application-prod.yaml：

sample:
  value: production

以及以下（非常简单的）spring boot应用程序：

package com.example.demo;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.context.event.ApplicationStartedEvent;
import org.springframework.context.event.EventListener;

@SpringBootApplication
public class DemoApplication {

    @Value("${sample.value}")
    private String sampleValue;
    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);

    }

    @EventListener
    public void onAppStarted(ApplicationStartedEvent evt) {
        System.out.println("Sample Value: " + sampleValue);
    }

}

即使我不提供任何标志，此配置也可以使用：java -jar myapp.jar

所以这里必须还有其他与您的代码相关的东西。

不看应用程序就很难说出什么问题了，但是我确实发现了一个“可疑”的声明：

您说，不管您尝试什么：

以下配置文件处于活动状态：swagger，dev

现在，“ swagger”简介来自何处？我没有看到任何参考。如果您使用java -jar myapp.jar运行该应用程序，那么我看到的一种可能性是，某个地方的spring.factories文件定义了一个EnvironmentPostProcessor-它是一个钩子，您可以在其中“摆弄”配置文件，并且其他事情（以代码形式）“手动”添加活动配置文件。

因此，请检查这种可能性，不过，再次-您所做的操作在Spring Boot中是正确的（嗯，从技术上讲，您不需要输入spring.profiles.default，但这无害）

Answer 2

Spring Boot可以从许多位置加载相同的属性，您可以在here的文档中参考其加载顺序。

列表的上部比下部具有更高的加载优先级。这意味着您在application-xxx.yml中定义的内容可以被OS env变量或JVM属性中定义的相同属性覆盖。或其他.....

由于命令行参数的加载顺序很高，这意味着基本上您可以尝试通过在启动应用程序的命令中添加--spring.profiles.active=prod来使用它来设置配置文件，例如：

$ java -jar myproject.jar --spring.profiles.active=prod
