\#首先配置Bean

import com.vivo.admin_log.common.utils.YamlConfigurerUtil;
    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    import org.springframework.beans.factory.config.YamlPropertiesFactoryBean;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.core.io.ClassPathResource;
    import org.springframework.core.io.Resource;
    
    import java.util.Properties;
    
    /** * @author 72038611 */
    @Configuration
    public class BeanConfiguration { 
        private final Logger logger = LoggerFactory.getLogger(BeanConfiguration.class);
        @Bean
        public YamlConfigurerUtil ymlConfigurerUtil() { 
            //1:加载配置文件
            Resource app = new ClassPathResource("config/application.yml");
            Resource appDev = new ClassPathResource("config/application-dev.yml");
            Resource appProd = new ClassPathResource("config/application-prod.yml");
            YamlPropertiesFactoryBean yamlPropertiesFactoryBean = new YamlPropertiesFactoryBean();
            // 2:将加载的配置文件交给 YamlPropertiesFactoryBean
            yamlPropertiesFactoryBean.setResources(app);
            // 3：将yml转换成 key：val
            Properties properties = yamlPropertiesFactoryBean.getObject();
            String active = properties.getProperty("spring.profiles.active");
            if (active == "" || active == null) { 
                logger.error("未找到spring.profiles.active配置！");
            }else { 
                //判断当前配置是什么环境
                if ("dev".equals(active)) { 
                    yamlPropertiesFactoryBean.setResources(app,appDev);
                }else if("prod".equals(active)){ 
                    yamlPropertiesFactoryBean.setResources(app,appProd);
                }
            }
            // 4: 将Properties 通过构造方法交给我们写的工具类
            YamlConfigurerUtil ymlConfigurerUtil = new YamlConfigurerUtil(yamlPropertiesFactoryBean.getObject());
            return ymlConfigurerUtil;
        }
    }

\#工具类

import java.util.Properties;
    
    /** * @author 72038611 */
    public class YamlConfigurerUtil { 
        private static Properties ymlProperties = new Properties();
     
        public YamlConfigurerUtil(Properties properties){ 
            ymlProperties = properties;
        }
     
        public static String getStrYmlVal(String key){ 
            return ymlProperties.getProperty(key);
        }
     
        public static Integer getIntegerYmlVal(String key){ 
            return Integer.valueOf(ymlProperties.getProperty(key));
        }
    }
