springBoot通过YamlPropertiesFactoryBean读取yaml配置文件

public static Properties getProperties(){
   String fileName = “/application.yaml”；
 
    YamlPropertiesFactoryBean yaml = new YamlPropertiesFactoryBean();
    try {
        //绝对路径
        //yaml.setResources(new FileSystemResource(fileName))；
        yaml.setResources(new ClassPathResource(fileName));
        
    }catch (Exception e){
        
    }
    Properties properties =  yaml.getObject();
    String = properties.getProperty("key");
}
