【问题描述】：

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.

所以你可以看到我将 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 构建应用程序，但尽管如此，每次我运行生成的战争时都会显示 The following profiles are active: swagger,dev。

有人知道为什么没有加载 prod 配置文件吗？提前致谢。

【参考方案1】：

我已经在 spring-boot 2.1.4 上验证了以下配置：

application.yaml：

spring:
 profiles:
   active: dev

应用程序-dev.yaml：

sample:
  value: development

application-prod.yaml：

sample:
  value: production

还有以下（非常简单的）spring boot 应用：

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);
    

此配置有效，即使我不提供任何标志：java -jar myapp.jar

所以这里肯定有别的东西，和你的代码有关。

不看应用很难说是哪里出了问题，但我确实发现了一个“可疑”的说法：

你说，无论你尝试什么：

以下配置文件处于活动状态：swagger,dev

现在“swagger”个人资料从何而来？我没有看到任何提及它。如果您使用java -jar myapp.jar 运行应用程序，我可以看到的一种可能性是spring.factories 文件在某处定义了EnvironmentPostProcessor - 它是一个钩子，您可以在其中“摆弄”配置文件，除此之外添加活动配置文件“手动”（在代码中）。

所以请检查这种可能性，但再次 - 您所做的在 Spring Boot 中是正确的（嗯，从技术上讲，您不需要 spring.profiles.default 条目，但它没有害处）

【参考方案2】：

Spring Boot 可以从多个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。

列表中上部的加载优先级高于下部。这意味着您在application-xxx.yml 中定义的内容可以被操作系统环境变量或JVM 属性等中定义的相同属性覆盖.....

由于命令行参数的加载顺序非常高，这意味着您基本上可以尝试使用它来设置配置文件，方法是在启动应用程序的命令中添加--spring.profiles.active=prod，例如：

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