POI根据模板导出word文件
一、制作word模版，${xxxx}是一会要替换的内容，最下面的表格是要插入数据，根据是否以$开头来判断是需要替换还是插入数据。
????????注意如果是需要插入数据，制作的表格模版需要一行空行，也只能有一行空行，原因可以看代码的逻辑，表格中${header}和${hearder2}是放入需要替换的图片
二、添加poi所需要的jar包文件，我用的maven对jar包进行管理
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi</artifactId>
<version>3.11</version>
</dependency>
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi-ooxml</artifactId>
<version>3.11</version>
</dependency>
三、由于poi自身bug,会出现图片无法显示问题，这里需要自定义一个类继承XWPFDocument类，接下来使用的都是我们自己创建的这个类来操作word对象，这个类对XWPFDocument进行了继承，所以不用担心会有什么问题
import java.io.InputStream;
import org.apache.poi.openxml4j.opc.OPCPackage;
import org.apache.poi.xwpf.usermodel.XWPFDocument;
import org.apache.poi.xwpf.usermodel.XWPFParagraph;
import org.apache.xmlbeans.XmlException;
import org.apache.xmlbeans.XmlToken;
import org.openxmlformats.schemas.drawingml.x2006.main.CTNonVisualDrawingProps;
import org.openxmlformats.schemas.drawingml.x2006.main.CTPositiveSize2D;
import org.openxmlformats.schemas.drawingml.x2006.wordprocessingDrawing.CTInline;
public class CustomXWPFDocument extends XWPFDocument {
public CustomXWPFDocument(InputStream in) throws java.io.IOException {
super(in);
}
public CustomXWPFDocument() {
super();
}
public CustomXWPFDocument(OPCPackage pkg)throws java.io.IOException {
super(pkg);
}
/**
* @param id
* @param width 宽
* @param height 高
* @param paragraph 段落
*/
public void createPicture(int id, int width, int height,XWPFParagraph paragraph) {
final int EMU = 9525;
width *= EMU;
height *= EMU;
String blipId = getAllPictures().get(id).getPackageRelationship().getId();
CTInline inline = paragraph.createRun().getCTR().addNewDrawing().addNewInline();
String picXml = ""
+"<a:graphic xmlns:a="http://schemas.openxmlformats.org/drawingml/2006/main">"

inline.addNewGraphic().addNewGraphicData();
XmlToken xmlToken = null;
try{
xmlToken = XmlToken.Factory.parse(picXml);
}catch(XmlException xe) {
xe.printStackTrace();
}
inline.set(xmlToken);
inline.setDistT(0);
inline.setDistB(0);
inline.setDistL(0);
inline.setDistR(0);
CTPositiveSize2D extent = inline.addNewExtent();
extent.setCx(width);
extent.setCy(height);
CTNonVisualDrawingProps docPr = inline.addNewDocPr();
docPr.setId(id);
docPr.setName("图片"+ id);
docPr.setDescr("测试");
}
}

五、最后就是进行测试了，我是用的是ssm框架，这里放出测试代码
@RequestMapping("exportWordData")
public void exportWordData(HttpServletRequest request,HttpServletResponse response){
WordUtils wordUtil=new WordUtils();
Map<String, Object> params = new HashMap<String, Object>();
params.put("${position}", "java开发");
params.put("${name}", "段然涛");
params.put("${sex}", "男");

params.put("${xueLi}", "本科");
params.put("${school}", "江西科技师范大学");
params.put("${phone}", "177");
params.put("${eMail}", "157");
try{
Map<String,Object> header = new HashMap<String, Object>();
header.put("width", 100);
header.put("height", 150);
header.put("type", "jpg");
header.put("content", WordUtils.inputStream2ByteArray(new FileInputStream("C:/Users/Administrator/Desktop/jar包/11.jpg"), true));
params.put("${header}",header);
Map<String,Object> header2 = new HashMap<String, Object>();
header2.put("width", 100);
header2.put("height", 150);
header2.put("type", "jpg");
header2.put("content", WordUtils.inputStream2ByteArray(new FileInputStream("C:/Users/Administrator/Desktop/jar包/22.jpg"), true));
params.put("${header2}",header2);
List<List<String[]>> list = new ArrayList<List<String[]>>();
List<String[]> testList = new ArrayList<String[]>();//一个需要插入的表是一个集合
testList.add(new String[]{"1","1AA","1BB","1CC"});
testList.add(new String[]{"2","2AA","2BB","2CC"});
testList.add(new String[]{"3","3AA","3BB","3CC"});
testList.add(new String[]{"4","4AA","4BB","4CC"}); list.add(testList);
String path="C:/Users/Administrator/Desktop/jar包/mobanFile.docx"; //模板文件位置
String fileName= new String("测试文档.docx".getBytes("UTF-8"),"iso-8859-1"); //生成word文件的文件名
wordUtil.getWord(path,params,list,fileName,newFilePath);
}catch(Exception e){
e.printStackTrace();
}
}

word转PDF
WORD转PDF所需jar包：

PDF转图片所需jar包：
https://yangtaotao.lanzous.com/ice169c
word转pdf使用的是ASPOSE.word，它的licence需要收费，百度有的文章中有，大家可以自行百度，这里就不放了。调用时传入word的路径和生成后的pdf的路径就行。
注意：在linux下不可以直接FileOutputSteram(path)生成文件，所以需要先new File(path)，如果生成之后的文件中文乱码，可能是服务器没有字库，安装一个就可以了

*
* 由于ASPOSE比较吃内存，操作大一点的文件就会堆溢出，所以请先设置好java虚拟机参数：-Xms512m -Xmx512m(参考值)<br>

PDF转图片再插入PDF中（防止PDF被修改）
公司大佬说这种防止修改的方法在pdf有多页时可能会出问题，也没测试过，试过的朋友帮忙评论一下
public static String pdf2Image(String PdfFilePath) throws Exception {
