Priority SpringBoot profile

Project structure

Priority profile

application.properties and application.yml file by priority in descending order at the following four positions:

1. file: ./ config / (current project path config directory);
2. file: ./ (under the current project path);
3. classpath: / config / (classpath directory config);
4. classpath: / (classpath config).

Source code shows:

public class ConfigFileApplicationListener
		implements EnvironmentPostProcessor, SmartApplicationListener, Ordered {
// Note the order is from least to most specific (last one wins)
private static final String DEFAULT_SEARCH_LOCATIONS = "classpath:/,classpath:/config/,file:./,file:./config/";

// 省略其它代码
}

To port configuration, for example

• In the resources / config file directory configuration is provided to the port 8888;
• In the resources / settings file directory configuration port 8080;
• In the config directory path the class profile is set to 6666 ports;
• In class path profile is set to 5555 ports;

operation result:

Custom binding profile

1. CustomizedFile 类

   /**
    * 自定义配置文件, 需要配合使用后@Configuration和@PropertySource("classpath:customized-file.properties")来指定
    * @author fengxuechao
    */
   @Configuration
   @ConfigurationProperties(prefix = "customizedFile")
   @PropertySource("classpath:customized-file-${spring.profiles.active}.properties")
   public class CustomizedFile {
       private String name;
       private String author;
       private String path;
       private String description;
       // 省略 setter/getter
   }
   

   See ${spring.profiles.active}, you must know the smart way to achieve this is spring boot environment and more custom configuration files.
   Effective configuration file is ${spring.profiles.active}specified in the configuration file, the entry into force of the case herein is customized-file-dev.properties.
   Then continue to create a profile verification

2. customized-file.properties

   customizedFile.name=自定义配置文件名
   customizedFile.author=作者名
   customizedFile.path=路径地址
   customizedFile.description=看到这个就表明自定义配置文件成功了
   

3. customized-file-dev.properties

   customizedFile.description=DEV:看到这个就表明自定义配置文件成功了
   

4. operation result:

   

   Conclusion: Only customized-file-dev.propertiesconfigured in property to take effect
