java进行url编码和解码

public static String getURLEncoderString(String str) {
        String result = "";
        if (null == str) {
            return "";
        }
        try {
            result = java.net.URLEncoder.encode(str, "UTF-8");
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        }
        return result;
    }

    public static String URLDecoderString(String str) {
        String result = "";
        if (null == str) {
            return "";
        }
        try {
            result = java.net.URLDecoder.decode(str, "UTF-8");
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        }
        return result;
    }

注意:java.net的url编码方法在对一些特殊符号编码时有个bug,如:+号decord时,+号会变成空格,需要把+号替换成%2B,str=str.replaceAll("\+", "%2B");
