Spring 配置文件值混合

Question

我正在使用 Spring Boot 1.4.3.RELEASE 和 gradle 2.13 来开发 api。在本地环境中，“local”配置文件运行良好，但在 Linux/Unix 服务器中部署代码时遇到问题。

这是我的 application.yml，有两个配置文件：dev 和 local

---

spring:
  profiles:
    active: dev

server:
  context-path: /api/v1
  port: 8080

build:
  version: 1.0.0

cache:
  storage:
    path: '/home/user/content/storage/'


---

spring:
  profiles:
    active: local

server:
  context-path: /content-delivery/api/v1
  port: 8081

build:
  version: 1.0.0

cache:
  storage:
    path: '/Yogen/api/code/cachedData'

我用来部署 war 文件的命令是：

jdk1.8.0_112/bin/java -jar _-Dspring.profiles.active=dev content-delivery.jar

当我运行我的 war 它只使用一个配置文件时工作正常，但是一旦我添加了另一个配置文件，我得到的值混淆导致错误如下：

PropertyPlaceholderConfigurer 已配置如下：

@Configuration
public class PropertyConfiguration {

    @Bean
    @Profile("dev")
    public static PropertyPlaceholderConfigurer developmentPropertyPlaceholderConfigurer() {
        PropertyPlaceholderConfigurer configurer = new PropertyPlaceholderConfigurer();
        configurer.setLocation(new FileSystemResource("/home/542596/content-api/resources/app-dev.properties"));
        configurer.setIgnoreUnresolvablePlaceholders(true);
        return configurer;
}
}

控制台显示正在读取的属性文件是正确的，配置文件也是 'dev'，但是端口已启动，上下文路径和其他值是从“local”配置文件中获取的，而不是“ dev'个人资料。

我错过了什么？？谢谢。

Answer 1

您的个人资料正在被覆盖。

使用 bootstrap.yml

更好地引导您的应用程序

并且有两个application.yml如下：

application-dev.yml
application-local.yml

在 bootstrap.yml 中设置配置文件以决定加载哪个属性文件：

    spring:
         profiles:
             active : dev # choose which application properties to load dev/local

Answer 2

如@Barath 所述，您不能在单个 application.yml 文件中分隔配置文件属性。为每个配置文件创建一个yml文件，命名如下

application-{profile}.yml

我不会使用 bootstrap.yml 来指定要加载的配置文件，因为如果可能的话，您会希望将其外部化，因此最好通过 -Dspring.profiles.active=dev 将其传递给 VM。

Answer 3

我们还有另一个类似于@Maxwell 答案的选项，而不是通过 VM 属性传递配置文件：

您可以拥有以下文件：

application.yml 
application-dev.yml
application-local.yml

并在 application.yml 中定义配置文件：

spring:
    profiles:
       active : dev

这确保了 application.yml 和 application-dev.yml 的加载。
