springboot优雅的获取yml配置（区分生产环境和测试环境）

#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));
}
}
