由于系统之前使用了是itext进行转换的，现在已经不是开源的工具了，需要收费，然后进行改造，具体处理如下。

java
public static void writeWordModle(String inPath, String outPath, Map<String, String> params,String rootpath) throws Exception {
FileInputStream is = null;
FileOutputStream targetpdf = null;
WordprocessingMLPackage wordMLPackage = null;
CustomXWPFDocument doc = null;
ByteArrayOutputStream baos = null;
InputStream inputStream = null;
try {
// 加载 Word 文档
File file = new File(inPath);
is = new FileInputStream(file);
doc = new CustomXWPFDocument(is);
// 替换文本和表格中的变量
WordUtils wordUtil = new WordUtils();
wordUtil.replaceInPara(doc, params); // 替换文本里面的变量
wordUtil.replaceInTable(doc, params); // 替换表格里面的变量
// 将 XWPFDocument 转换为字节数组
baos = new ByteArrayOutputStream();
doc.write(baos);
baos.flush();
byte[] docBytes = baos.toByteArray();
// 使用字节数组创建输入流
inputStream = new ByteArrayInputStream(docBytes);
// 将输入流转换为 WordprocessingMLPackage
wordMLPackage = WordprocessingMLPackage.load(inputStream);
// 设置字体映射器
IdentityPlusMapper fontMapper = new IdentityPlusMapper();
//加载字体
fontMapper = setFontMapper(fontMapper);
//解决宋体（正文）和宋体（标题）的乱码问题,以下是在linux的关键
PhysicalFonts.put("PMingLiU", PhysicalFonts.get("SimSun"));
PhysicalFonts.put("新細明體", PhysicalFonts.get("SimSun"));
wordMLPackage.setFontMapper(fontMapper);
// 执行转换
targetpdf = new FileOutputStream(outPath);
Docx4J.toPDF(wordMLPackage, targetpdf);
} catch (Exception e) {
e.printStackTrace();
throw e;
} finally {
// 关闭所有流
close(is);
close(targetpdf);
close(baos);
close(inputStream);
}
}因为我是通过word模版生成了流然后通过流转换成pdf的，可以使用File docFile = new File(docxPath);替代代码中的 inputStream = new ByteArrayInputStream(docBytes);
java
//解决宋体（正文）和宋体（标题）的乱码问题,以下是在linux的关键
PhysicalFonts.put("PMingLiU", PhysicalFonts.get("SimSun"));
PhysicalFonts.put("新細明體", PhysicalFonts.get("SimSun"));这句很关键，我测试了很久找了很多资料，这个解决了linux环境乱码的问题。

fontMapper.put("新細明體",PhysicalFonts.get("SimSun"));
return fontMapper;
}设置字体，主要是windows使用，其实不设置也没问题。以上基本解决了代码的问题。
linux字体环境准备及处理
1、复制windows的C:\Windows\Fonts\下的所有字体库，放在桌面的fonts文件夹里
2、在linux目录/usr/share/fonts/chinese 创建文件夹chinese ，如果文件夹不存在，手动创建
3、把fonts拷贝上去，并给他授权chmod -R 755 /usr/share/fonts/chinese
4、# mkfontscale （如果提示 mkfontscale: command not found，需自行安装 # yum install mkfontscale ）
mkfontdir
fc-cache -fv （如果提示 fc-cache: command not found，则需要安装# yum install fontconfig
5、到路径vi /etc/fonts/fonts.conf 修改配置，把/usr/share/fonts/chinese添加进去
6、最后执行，fc-cache和fc-list :lang=zh
bash
/usr/share/fonts/chinese/simsun.ttc: SimSun\-PUA,宋体\-PUA:style=Regular
/usr/share/fonts/chinese/simsun.ttc: NSimSun,新宋体:style=Regular
/usr/share/fonts/chinese/simsunb.ttf: SimSun\-ExtB:style=Regular,Normal,oby?ejné,Standard,Κανονικ?,Normaali,Normál,Normale,Standaard,Normalny,Обычный,Normálne,Navadno,Arrunta
/usr/share/fonts/chinese/SimsunExtG.ttf: SimSun\-ExtG:style=Regular
/usr/share/fonts/chinese/simsun.ttf: SimSun,宋体:style=Regular
/usr/share/fonts/chinese/simsun.ttc: SimSun,宋体:style=Regular出现上面的类似即表示成功。
