【Java愚公】java读取自定义yml文件

获取自定义yml内容代码

package;

import org.yaml.snakeyaml.Yaml;

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

public class Main {

    private static final Map<String, String> envVariable = new HashMap<String, String>();

    public static void main(String[] args) {
        InputStream inputStream = Main.class.getClassLoader().getResourceAsStream("ws.yml");
        Yaml yaml = new Yaml();
        Map map = yaml.loadAs(inputStream, Map.class);

        parseMap(map, null);
        String ws = envVariable.get("ws");
        System.out.println("ws = " + ws);
    }

    private static void parseMap(Map map, String pre) {
        map.forEach((k, v) -> {
            if (v instanceof Map) {
                parseMap((Map) v, pre == null ? (String) k : pre + "." + k);
            } else {
                envVariable.put(pre == null ? (String) k : pre + "." + k, String.valueOf(v));
            }
        });
    }

}

ws.yml 文件

# ws配置
ws:
  - puburl: xxxx
    pubclass: xxxxxx
  - puburl: xxxx
    pubclass: xxxxxx

输出结果:

ws = [{puburl=xxxx, pubclass=xxxxxx}, {puburl=xxxx, pubclass=xxxxxx}]
