SpringBoot工具类获取yml配置文件内容

package com.common.test.utils;

import org.springframework.beans.factory.config.YamlPropertiesFactoryBean;
import org.springframework.core.io.ClassPathResource;
import org.springframework.core.io.Resource;

import java.util.Properties;

/**

public class PropertiesUtils {
    private static String PROPERTY_NAME = "application-common.yml";

    public static Object getCommonYml(Object key){
        Resource resource = new ClassPathResource(PROPERTY_NAME);
        Properties properties = null;
        try {
            YamlPropertiesFactoryBean yamlFactory = new YamlPropertiesFactoryBean();
            yamlFactory.setResources(resource);
            properties =  yamlFactory.getObject();
        } catch (Exception e) {
            e.printStackTrace();
            return null;
        }
        return properties.get(key);
    }

    public static void main(String[] args) {
        System.out.println(getCommonYml("file.upload.path"));
    }
}

application.yml配置信息:

spring:
  profiles:
    include: jdbc,common

特别注意要将application-common.yml 加入到classpath 中去，不然可能读取不到文件，这边例子只是使用的classPath中加载配置，各位也可以从文件系统获取，具体还得看各自需要了，建议使用classPath加载。
