是否有Java方法将一组参数编码为URL查询组件？

我最终写了我自己的。可以这样称呼

URIUtils.withQuery(uri, "param1", "value1", "param2", "value2");

这还不错。

public static URI withQuery(URI uri, Map<String, String> params) {    StringBuilder query = new StringBuilder();    char separator = '?';    for (Entry<String, String> param : params.entrySet()) {        query.append(separator);        separator = '&';        try { query.append(URLEnprer.enpre(param.getKey(), "UTF-8")); if (!StringUtils.isEmpty(param.getValue())) {     query.append('=');     query.append(URLEnprer.enpre(param.getValue(), "UTF-8")); }        } catch (UnsupportedEncodingException e) { throw new RuntimeException(e);        }    }    return URI.create(uri.toString() + query.toString());}public static URI withQuery(URI uri, String... params) {    Map<String, String> map = new linkedHashMap<String, String>();    for (int i = 0; i < params.length; i += 2) {        String key = params[i];        String val = i + 1 < params.length ? params[i + 1] : "";        map.put(key, val);    }    return withQuery(uri, map);}
