Warning:(36, 30) java: java.net.URLEncoder中的encode(java.lang.String)已过时

一、查看过时的encode方法

    @Deprecated
    public static String encode(String s) {

        String str = null;

        try {
            str = encode(s, dfltEncName);
        } catch (UnsupportedEncodingException e) {
            // The system should always have the platform default
        }

        return str;
    }

二、查看新的的encode方法

    public static String encode(String s, String enc)
        throws UnsupportedEncodingException {

        boolean needToChange = false;
        StringBuffer out = new StringBuffer(s.length());
        Charset charset;
        CharArrayWriter charArrayWriter = new CharArrayWriter();

        if (enc == null)
            throw new NullPointerException("charsetName");

        try {
            charset = Charset.forName(enc);
        } catch (IllegalCharsetNameException e) {
            throw new UnsupportedEncodingException(enc);
        } catch (UnsupportedCharsetException e) {
            throw new UnsupportedEncodingException(enc);
        }

        for (int i = 0; i < s.length();) {
            int c = (int) s.charAt(i);
            //System.out.println("Examining character: " + c);
            if (dontNeedEncoding.get(c)) {
                if (c == ' ') {
                    c = '+';
                    needToChange = true;
                }
                //System.out.println("Storing: " + c);
                out.append((char)c);
                i++;
            } else {
                // convert to external encoding before hex conversion
                do {
                    charArrayWriter.write(c);
                    
                    if (c >= 0xD800 && c <= 0xDBFF) {
                        
                        if ( (i+1) < s.length()) {
                            int d = (int) s.charAt(i+1);
                            
                            if (d >= 0xDC00 && d <= 0xDFFF) {
                                
                                charArrayWriter.write(d);
                                i++;
                            }
                        }
                    }
                    i++;
                } while (i < s.length() && !dontNeedEncoding.get((c = (int) s.charAt(i))));

                charArrayWriter.flush();
                String str = new String(charArrayWriter.toCharArray());
                byte[] ba = str.getBytes(charset);
                for (int j = 0; j < ba.length; j++) {
                    out.append('%');
                    char ch = Character.forDigit((ba[j] >> 4) & 0xF, 16);
                    // converting to use uppercase letter as part of
                    // the hex value if ch is a letter.
                    if (Character.isLetter(ch)) {
                        ch -= caseDiff;
                    }
                    out.append(ch);
                    ch = Character.forDigit(ba[j] & 0xF, 16);
                    if (Character.isLetter(ch)) {
                        ch -= caseDiff;
                    }
                    out.append(ch);
                }
                charArrayWriter.reset();
                needToChange = true;
            }
        }

        return (needToChange? out.toString() : s);
    }

三、修改成新的的encode方法

     try{
            reString = URLEncoder.encode(reString,"UTF-8");
        }catch (UnsupportedEncodingException ue){
            log.error("编码出错...");
            throw new UserException(ResultCode.FAILED);
        }
