java 正则替换 域名/ip和端口

public String replaceDomainAndPort(String domain,String port,String url){
    String url_bak = "";
    if(url.indexOf("//") != -1 ){
        String[] splitTemp = url.split("//");
        url_bak = splitTemp[0]+"//";
        if(port != null){
            url_bak = url_bak + domain+":"+port;
        }else{
            url_bak = url_bak + domain;
        }

        if(splitTemp.length >=1 && splitTemp[1].indexOf("/") != -1){
            String[] urlTemp2 = splitTemp[1].split("/");
            if(urlTemp2.length > 1){
                for(int i = 1;i < urlTemp2.length; i++){
                    url_bak = url_bak +"/"+urlTemp2[i];
                }
            }
            System.out.println("url_bak:"+url_bak);
        }else{
            System.out.println("url_bak:"+url_bak);
        }
    }
    return url_bak;
}

String replaceUrl=replaceDomainAndPort("192.168.10.196","81",laborCompanyRelated.getPhotoPath());

js正则替换url的域名/ip和端口

url = url.replace(/^https:\/\/[^/]+\//, "https://192.168.10.196:81/");

url = url.replace(/^http:\/\/[^/]+\//, "http://192.168.10.196:81/");

记录一下,方便后续使用
