一个map 拼结参数的工具类：

public final class ParamKit {

    public static Map<String, String> of() {
        return new HashMap<>();
    }

    public static Map<String, String> of(String... args) {
        List<Pair<String, String>> pairs = new ArrayList<>();
        for (int i = 0; i < args.length; i+=2) {
            pairs.add(Pair.create(args[i], args[i + 1]));
        }
        return of(pairs);
    }


    public static Map<String, String> of(List<Pair<String, String>> kvs) {
        Map<String, String> params = new HashMap<>();
        if (kvs != null && !kvs.isEmpty()) {
            for (Pair<String, String> kv : kvs) {
                params.put(kv.first, kv.second);
            }
        }
        return params;
    }

    public static Map<String, String> of(Pair<String, String>... pairs) {
        if (pairs != null) {
            return of(Arrays.asList(pairs));
        }
        return of();
    }


    public static Map<String, String> page(int page, int limit, Pair<String, String>... pairs) {
        Map<String, String> params = of(Pair.create("page", "" + page), Pair.create("limit", "" + limit));
        if (pairs != null && pairs.length > 0) {
            for (Pair<String, String> kv : pairs) {
                params.put(kv.first, kv.second);
            }
        }
        return params;
    }

}

使用

ParamKit.page(0,9999,Pair.create("regionCode",regionCode),Pair.create("macCode",macCode))
