Spring Boot:在PropertySourcesPlaceholderConfigurer加载的文件中忽略了配置文件 [英] Spring Boot: Profiles ignored in PropertySourcesPlaceholderConfigurer loaded file

问题描述

我有一个作为Spring Boot项目的库.该库有一个library.yml文件，其中包含用于其配置的dev和prod道具:

I have a library that is a Spring Boot project. The library has a library.yml file that contains dev and prod props for its configuration:

library.yml

---
spring:
    profiles: 
        active: dev
---
spring:
    profiles: dev
env: dev
---
spring:
    profiles: prod
env: prod

另一个应用程序使用此库并使用以下命令加载道具:

Another application uses this library and loads the props using:

@Bean
public static PropertySourcesPlaceholderConfigurer dataProperties() {
  PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer = new PropertySourcesPlaceholderConfigurer();
  YamlPropertiesFactoryBean yaml = new YamlPropertiesFactoryBean();
  yaml.setResources(new ClassPathResource("library.yml"));
  propertySourcesPlaceholderConfigurer.setProperties(yaml.getObject());
  return propertySourcesPlaceholderConfigurer;
}

其application.yml表示要使用开发道具:

And its application.yml says to use dev props:

---
spring:
    profiles: 
        active: dev

但是当我检查env的值时，我得到"prod".为什么?

But when I check the value of env, I get "prod". Why?

如何告诉Spring Boot在library.yml中使用活动的(例如dev)配置文件道具?

How can I tell Spring Boot to use the active (e.g. dev) profile props in library.yml?

注意:我更喜欢使用.yml而不是.properties文件.

Note: I prefer to use .yml instead .properties files.

推荐答案

默认情况下，PropertySourcesPlaceholderConfigurer对于仅获取个人档案专用道具一无所知.如果在文件(例如env)中多次定义了prop，它将绑定与该prop的最后一次出现相关的值(在本例中为prod).

By default, the PropertySourcesPlaceholderConfigurer knows nothing about only getting profile specific props. If you have a prop defined multiple times in a file such as env, it will bind the value associated with the last occurrence of that prop (in this case prod).

要使其绑定与特定配置文件匹配的道具，请设置配置文件文档匹配器.概要文件文档匹配者将需要知道可以从环境中获取的活动概要文件.这是代码:

To make it bind props matching a specific profile, set a profile document matcher. The profile document matcher will need to know the active profile which can be obtained from the environment. Here's the code:

@Bean
public static PropertySourcesPlaceholderConfigurer dataProperties(Environment environment) {
  PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer = new PropertySourcesPlaceholderConfigurer();
  YamlPropertiesFactoryBean yaml = new YamlPropertiesFactoryBean();
  SpringProfileDocumentMatcher matcher = new SpringProfileDocumentMatcher();
  matcher.addActiveProfiles(environment.getActiveProfiles());
  yaml.setDocumentMatchers(matcher);
  yaml.setResources(new ClassPathResource("library.yml"));
  propertySourcesPlaceholderConfigurer.setProperties(yaml.getObject());
  return propertySourcesPlaceholderConfigurer;
}
