java POI HTML转Word 两种方式
说明，不论使用哪种方式，都不能引用CSS来渲染样式，而是使用style,或者将样式放在当前页面的<style></style>中
方法一、
1、引用的jar包
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi</artifactId>
<version>4.1.0</version>
</dependency>
2、核心代码
String html = "<div>测试内容</div";
POIFSFileSystem poifs = null;
FileOutputStream ostream = null;
ByteArrayInputStream bais = null;
String uuid = "测试.doc";
File file = null;
try {
//HTML内容必须被<html><body></body></html>包装
fileParam.setcContent("<html><body>" + html + "</body></html>");
byte[] b = fileParam.getcContent().getBytes();
bais = new ByteArrayInputStream(b);
poifs = new POIFSFileSystem();
DirectoryEntry directory = poifs.getRoot();
//WordDocument名称不允许修改
directory.createDocument("WordDocument", bais);
ostream = new FileOutputStream(uuid);
poifs.writeFilesystem(ostream);//当前目录下就生成了一个测试.doc的文档
} catch (Exception e) {
logger.error("exception is {}", e);
} finally {
IOUtils.closeQuietly(poifs);
IOUtils.closeQuietly(ostream);
IOUtils.closeQuietly(bais);
try {
FileUtils.forceDelete(file);
} catch (Exception e2) {
}
}
方法二
/**
* word格式html的标签头
*/
public static final String HTML_TAG_BGN = "<html xmlns=\"http://www.w3.org/TR/REC-html40\" xmlns:v=\"urn:schemas-microsoft-com:vml\" xmlns:o=\"urn:schemas-microsoft-com:office:office\" xmlns:w=\"urn:schemas-microsoft-com:office:word\" xmlns:m=\"http://schemas.microsoft.com/office/2004/12/omml\"><head><meta name=\"ProgId\" content=\"Word.Document\" /><meta name=\"Generator\" content=\"Microsoft Word 12\" /><meta name=\"Originator\" content=\"Microsoft Word 12\" /> <!--[if gte mso 9]><xml><w:WordDocument><w:View>Print</w:View></w:WordDocument></xml><[endif]-->";
public filePath downloadWordReport(String htmlForPrint) {
try {
String wordString = htmlForPrint.replaceAll("<head>", "").replaceAll("<html>", HTML_TAG_BGN );
String fileName = new String("测试文件.doc".getBytes(), "UTF-8");
//上传文件方法
return this.upload(new ByteArrayInputStream(wordString.getBytes()), fileName);
} catch (Exception e) {
return null;
}
}
