使用docx4j 实现word转pdf（linux乱码处理）

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。

<dependency><groupId>org.docx4j</groupId><artifactId>docx4j</artifactId><version>6.1.2</version><exclusions><exclusion><groupId>org.slf4j</groupId><artifactId>slf4j-log4j12</artifactId></exclusion><exclusion><groupId>xalan</groupId><artifactId>xalan</artifactId></exclusion></exclusions></dependency><dependency><groupId>org.docx4j</groupId><artifactId>docx4j-export-fo</artifactId><version>6.0.0</version><exclusions><exclusion><groupId>org.slf4j</groupId><artifactId>slf4j-log4j12</artifactId></exclusion><exclusion><groupId>xalan</groupId><artifactId>xalan</artifactId></exclusion></exclusions></dependency>

以上排查一下日志，因为和自己的有冲突，所以，自己项目看情况而定。

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 WordprocessingMLPackagewordMLPackage = 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);

 //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。

/** * 字体设置* @param mlPackage* @throws Exception*/private static IdentityPlusMapper setFontMapper( IdentityPlusMapper fontMapper) throws Exception {fontMapper.put("隶书", PhysicalFonts.get("LiSu"));fontMapper.put("宋体", PhysicalFonts.get("SimSun"));fontMapper.put("微软雅黑", PhysicalFonts.get("Microsoft Yahei"));fontMapper.put("黑体", PhysicalFonts.get("SimHei"));fontMapper.put("楷体", PhysicalFonts.get("KaiTi"));fontMapper.put("新宋体", PhysicalFonts.get("NSimSun"));fontMapper.put("华文行楷", PhysicalFonts.get("STXingkai"));fontMapper.put("华文仿宋", PhysicalFonts.get("STFangsong"));fontMapper.put("仿宋", PhysicalFonts.get("FangSong"));fontMapper.put("幼圆", PhysicalFonts.get("YouYuan"));fontMapper.put("华文宋体", PhysicalFonts.get("STSong"));fontMapper.put("华文中宋", PhysicalFonts.get("STZhongsong"));fontMapper.put("等线", PhysicalFonts.get("SimSun"));fontMapper.put("等线 Light", PhysicalFonts.get("SimSun"));fontMapper.put("华文琥珀", PhysicalFonts.get("STHupo"));fontMapper.put("华文隶书", PhysicalFonts.get("STLiti"));fontMapper.put("华文新魏", PhysicalFonts.get("STXinwei"));fontMapper.put("华文彩云", PhysicalFonts.get("STCaiyun"));fontMapper.put("方正姚体", PhysicalFonts.get("FZYaoti"));fontMapper.put("方正舒体", PhysicalFonts.get("FZShuTi"));fontMapper.put("华文细黑", PhysicalFonts.get("STXihei"));fontMapper.put("宋体扩展",PhysicalFonts.get("simsun-extB"));fontMapper.put("仿宋_GB2312",PhysicalFonts.get("FangSong_GB2312"));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  

/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。
