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
