我想解码一个URL，但只用于%编码。我想保留非%编码不变：

e、 g

但是，如果：

url = http://www.domain.com/News/politics/MPs+risk+losing+parliamentary+immunity+/-/1064/1395978/-/lvylki/-/index.html

URLDecoder.decode(url, "UTF-8") = http://www.domain.com/News/politics/MPs risk losing parliamentary immunity /-/1064/1395978/-/lvylki/-/index.html

我想：

URLDecoder.decode(url, "UTF-8") = http://www.domain.com/News/politics/MPs+risk+losing+parliamentary+immunity+/-/1064/1395978/-/lvylki/-/index.html

如何避免

urldecker.decode（）

从解码+变为“”。通常，我希望保留非%编码字符串不变，即仅转换%编码

URLDecoder.decode(url.replaceAll("\\+", "%2B"))

URLDecoder.decode(url.replaceAll("\\+", "%2B"))
