程序猿最近在做对文件操作的功能，搜索到docx4J的介绍，使用起来不错，所以这里整理记录下。
1.pom文件增加
<!-- https://mvnrepository.com/artifact/org.docx4j/docx4j -->
<dependency>
<groupId>org.docx4j</groupId>
<artifactId>docx4j</artifactId>
<version>6.0.1</version>
</dependency>
<!-- https://mvnrepository.com/artifact/org.docx4j/docx4j-export-fo -->
<!-- 转出pdf需要 -->
<dependency>
<groupId>org.docx4j</groupId>
<artifactId>docx4j-export-fo</artifactId>
<version>6.1.0</version>
</dependency>
2.基础创建
这是基本的操作，设定一个路径，如果文件不存在，则创建空文档，
private static String docxPath = "/Users/chenhailong/Desktop/helloworld.docx";
/**
* 获取文档可操作对象
* @param docxPath 文档路径
* @return
*/
static WordprocessingMLPackage getWordprocessingMLPackage(String docxPath) {
WordprocessingMLPackage wordMLPackage = null;
if(StringUtils.isEmpty(docxPath)) {
try {
wordMLPackage = WordprocessingMLPackage.createPackage();
} catch (InvalidFormatException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
File file = new File(docxPath);
if(file.isFile()) {
try {
wordMLPackage = WordprocessingMLPackage.load(file);
} catch (Docx4JException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
return wordMLPackage;
}
3.追加文档内容
/**
* 像文档中追加内容(默认支持中文)
* 先清空,在生成,防重复
*/
public static void addParagraph() {
WordprocessingMLPackage wordprocessingMLPackage;
try {
//先加载word文档
wordprocessingMLPackage = WordprocessingMLPackage.load(new File(docxPath));
// Docx4J.load(new File(docxPath));
//增加内容
wordprocessingMLPackage.getMainDocumentPart().addParagraphOfText("你好!");
wordprocessingMLPackage.getMainDocumentPart().addStyledParagraphOfText("Title", "这是标题!");
wordprocessingMLPackage.getMainDocumentPart().addStyledParagraphOfText("Subtitle", " 这是二级标题!");
wordprocessingMLPackage.getMainDocumentPart().addStyledParagraphOfText("Subject", "试一试");
//保存文档
wordprocessingMLPackage.save(new File(docxPath));
} catch (Docx4JException e) {
logger.error("addParagraph to docx error: Docx4JException", e);
}
}
4.读取docx文件(这里不支持doc文件)
/**
* 读取word文件，这里没有区分 word中的样式格式
*/
public static void readParagraph(String path) {
try {
WordprocessingMLPackage wordprocessingMLPackage = getWordprocessingMLPackage(path);
String contentType = wordprocessingMLPackage.getContentType();
logger.info("contentType:"+contentType);
MainDocumentPart part = wordprocessingMLPackage.getMainDocumentPart();
List<Object> list = part.getContent();
System.out.println("content -> body -> "+part.getContents().getBody().toString());
for(Object o :list) {
logger.info("info:"+o);
}
}catch(Exception e) {
}
}
以下是读取到的内容

- 插入图片

File file = new File("/Users/chenhailong/Desktop/avatar.png");
try {
byte[] bytes = DocImageHandler.convertImageToByteArray(file);
DocImageHandler.addImageToPackage(wordprocessingMLPackage, bytes);
wordprocessingMLPackage.save(new File(docxPath));
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

6.导入类
项目引用很多jar,要引入正确的类
import org.docx4j.Docx4J;
import org.docx4j.Docx4jProperties;
import org.docx4j.convert.out.HTMLSettings;
import org.docx4j.jaxb.Context;
import org.docx4j.openpackaging.exceptions.Docx4JException;
