调用nacos的api获取nacos在线配置，并转为map

public void init() throws NacosException {
    String baseUrl = "http://nacos地址:8848/nacos/v1/cs/configs";
    try {
        UriComponentsBuilder builder = UriComponentsBuilder.fromHttpUrl(baseUrl)
                .queryParam("dataId", dataId)
                .queryParam("group", group)
                .queryParam("tenant", namespace);
        String result = restTemplate.getForEntity(builder.toUriString(), String.class).getBody();
        Map<String, Object> configMap = parseConfigString(result);
        System.out.println(configMap);
    } catch (Exception e) {
        e.printStackTrace();
    }
}

public static Map<String, Object> parseConfigString(String configStr) {
    String[] lines = configStr.split("\r?\n");
    Map<String, Object> resultMap = new HashMap<>();
    Map<String, Object> currentMap = resultMap;

    for (String line : lines) {
        String trimmedLine = line.trim();
        if (trimmedLine.isEmpty() || trimmedLine.startsWith("#")) {
            continue; // Skip empty lines or comments
        }

        if (trimmedLine.endsWith(":")) {
            // Key line
            String key = trimmedLine.substring(0, trimmedLine.length() - 1);
            currentMap.put(key, new HashMap<>());
            currentMap = (Map<String, Object>) currentMap.get(key);
        } else {
            // Value line
            int colonIndex = trimmedLine.indexOf(":");
            String key = trimmedLine.substring(0, colonIndex).trim();
            String value = trimmedLine.substring(colonIndex + 1).trim();
            currentMap.put(key, value);
        }
    }

    return resultMap;
