读取yaml工具类

package com.ainsg.apps.aop.common.utils;

import org.apache.ibatis.io.Resources;
import org.yaml.snakeyaml.Yaml;

import java.io.IOException;
import java.io.InputStream;
import java.util.Map;

/**

public class YamlUtil {

  /**
   * 读取 ymal
   *
   * @param path 需要读取的文件路径
   * @return Map
   */
  public static Map getReadAbleYaml(String path) {
    Yaml yaml = new Yaml();
    Map obj = null;
    InputStream ins = null;
    try {
      ins = Resources.getResourceAsStream(path);
      obj = (Map) yaml.load(ins);
    } catch (Exception e) {
      e.printStackTrace();
    } finally {
      try {
        if (ins != null) {
          ins.close();
        }
      } catch (IOException e) {
        e.printStackTrace();
      }
    }
    return obj;
  }
}
