yaml对应实体类

public class NetworkConfig {
    private Map<String, MspInfo> visitors;

    private Map<String, List<PeerNodeDTO>> orgs;

    public Map<String, MspInfo> getVisitors() {
        return visitors;
    }

    public void setVisitors(Map<String, MspInfo> visitors) {
        this.visitors = visitors;
    }

    public Map<String, List<PeerNodeDTO>> getOrgs() {
        return orgs;
    }

    public void setOrgs(Map<String, List<LinkedHashMap<String, String>>> orgs) {
        final Map<String, List<PeerNodeDTO>> tmpOrgs = new HashMap<>();
        orgs.forEach((k, v) -> {
            List<PeerNodeDTO> peerNodeDTO = JSONObject.parseObject(
                    JSONObject.toJSONString(v), new TypeReference<List<PeerNodeDTO>>(){});
            tmpOrgs.put(k, peerNodeDTO);
        });
