rtf乱码解决办法

首先，阐述下rtf，富文本格式文档，目前常用来做模板；

我遇到的问题是rtf中替换后的文本显示是正常的，rtf直接转pdf就不正常了，通过notpad++ 打开后发现rtf本身内容编码是我没有见过的（查资料说时ansi，具体我也不晓得了），我替换后的则是中文显示，这样转换后中文全部乱码；

解决办法如下，直接贴util类分享

package com.ywlqi.util;public class StringToRtfUtil{public static String chineseStrTortf(String content){StringBuffer sb = new StringBuffer("");if (content == null) return null;for (char c : content.toCharArray()) {if(isChinese(c)){System.out.println(c);sb.append(strToRtf(String.valueOf(c)));}else{sb.append(c);}}return sb.toString();}public static void main(String[] args) {System.out.println(chineseStrTortf("1）在合同有效期内，乙方为甲方提供简历库下载的用户名与初始密码"));}public static byte[] charToByte(char c) { byte[] b = new byte[2]; b[0] = (byte) ((c & 0xFF00) >> 8); b[1] = (byte) (c & 0xFF); return b; }public static boolean isChinese(char c) {
//          return c >= 0x4E00 &&  c <= 0x9FA5;// 根据字节码判断
          Character.UnicodeBlock ub = Character.UnicodeBlock.of(c);if (ub == Character.UnicodeBlock.CJK_UNIFIED_IDEOGRAPHS || ub == Character.UnicodeBlock.CJK_COMPATIBILITY_IDEOGRAPHS|| ub == Character.UnicodeBlock.CJK_UNIFIED_IDEOGRAPHS_EXTENSION_A || ub == Character.UnicodeBlock.CJK_UNIFIED_IDEOGRAPHS_EXTENSION_B|| ub == Character.UnicodeBlock.CJK_SYMBOLS_AND_PUNCTUATION || ub == Character.UnicodeBlock.HALFWIDTH_AND_FULLWIDTH_FORMS|| ub == Character.UnicodeBlock.GENERAL_PUNCTUATION) {return true;}return false;}public static String strToRtf(String content) {StringBuffer sb = new StringBuffer("");try {char[] digital = "0123456789ABCDEF".toCharArray();byte[] bs = null;bs = content.getBytes("GB2312");int bit;for (int i = 0; i < bs.length; i++) {bit = (bs[i] & 0x0f0) >> 4;sb.append("\\'");sb.append(digital[bit]);bit = bs[i] & 0x0f;sb.append(digital[bit]);}} catch (Exception e) {e.printStackTrace();}return sb.toString();}public static String byteToRtf(byte[] bs) {StringBuffer sb = new StringBuffer("");try {char[] digital = "0123456789ABCDEF".toCharArray();int bit;for (int i = 0; i < bs.length; i++) {bit = (bs[i] & 0x0f0) >> 4;sb.append("\\'");sb.append(digital[bit]);bit = bs[i] & 0x0f;sb.append(digital[bit]);}} catch (Exception e) {e.printStackTrace();}return sb.toString();}
}

在模板替换的时候使用

chineseStrTortf或者strToRtf即可，两者区别在于，你是把所有字符串转成rtf编码还是仅转换中文

rtfTemplate.put("value_taxAddr", StringToRtfUtil.strToRtf(taxAddr));

这样rtf文档显示正常，pdf也是正常的
