### application.yml ###

spring:
      profiles:
        active: @activatedProperties@

### application-dev.yml等 ###

string:
      ENV_YML_FILE_NAME: application-dev.yml

junit\uat\pro环境类型

string:
      ENV_YML_FILE_NAME: application-junit.yml

string:
      ENV_YML_FILE_NAME: application-uat.yml

string:
      ENV_YML_FILE_NAME: application-pro.yml

# 测试 #

### ConfigController.java ###

package com.ydfind.start.controller.test;
    
    import lombok.extern.slf4j.Slf4j;
    import org.springframework.beans.factory.annotation.Value;
    import org.springframework.web.bind.annotation.GetMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    /**
     * 配置信息的试验controller
     * @author ydfind
     * @date 2020.1.5
     */
    @RestController
    @Slf4j
    public class ConfigController {
    
        @Value("${spring.profiles.active}")
        private String active;
    
        @Value("${string.ENV_YML_FILE_NAME}")
        private String envFilename;
    
        @GetMapping("/config")
        public String getConfigs() {
            log.info("active = {}", active);
            log.info("the yml file name of env = {}", envFilename);
            return active + "," + envFilename;
        }
    }

### 结果 ###

即maven页会多出来profiles项，选择dev时，重新编译后，会加载application-dev.yml文件内容。
