有没有Java的http_build_query函数的Java等价物？

查看QueryStringBuilder类及其测试类:

private String httpBuildQuery(Map data)
        throws UnsupportedEncodingException {
    QueryStringBuilder builder = new QueryStringBuilder();
    for (Entry pair : data.entrySet()) {
        builder.addQueryParameter(pair.getKey(), pair.getValue());
    }
    return builder.encode("UTF-8");
}
