 yml样例

server:
  port: 8080
  tomcat:
    uri-encoding: UTF-8
    max-threads: 1000
    min-spare-threads: 30
  connection-timeout: 5000ms

import java.util.Map;
import org.yaml.snakeyaml.Yaml;
import com.alibaba.fastjson.JSONObject;

public class YamlTest {

	public static void main(String[] args) {

		String ymlStr = "server:\r\n" + 
				"  port: 8080\r\n" + 
				"  tomcat:\r\n" + 
				"    uri-encoding: UTF-8\r\n" + 
				"    max-threads: 1000\r\n" + 
				"    min-spare-threads: 30\r\n" + 
				"  connection-timeout: 5000ms";
		Yaml yaml = new Yaml();
		Map<String,Object> map= (Map<String, Object>) yaml.load(ymlStr);
		JSONObject jsonObject=new JSONObject(map);
		System.out.println(jsonObject.toString());
	}
}

输出：

{"server":{"port":8080,"tomcat":{"uri-encoding":"UTF-8","max-threads":1000,"min-spare-threads":30},"connection-timeout":"5000ms"}}
