說明，不論使用哪種方式，都不能引用CSS來渲染樣式，而是使用style,或者將樣式放在當前頁面的<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、核心代碼
String html = "<div>測試內容</div";
POIFSFileSystem poifs = null;
FileOutputStream ostream = null;
ByteArrayInputStream bais = null;
String uuid = "測試.doc";
File file = null;
try {
//HTML內容必須被<html><body></body></html>包裝
fileParam.setcContent("<html><body>" + html + "</body></html>");
byte[] b = fileParam.getcContent().getBytes();
bais = new ByteArrayInputStream(b);
poifs = new POIFSFileSystem();
DirectoryEntry directory = poifs.getRoot();
//WordDocument名稱不允許修改
directory.createDocument("WordDocument", bais);
ostream = new FileOutputStream(uuid);
poifs.writeFilesystem(ostream);//當前目錄下就生成了一個測試.doc的文檔
} 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的標簽頭
*/
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("測試文件.doc".getBytes(), "UTF-8");
//上傳文件方法
return this.upload(new ByteArrayInputStream(wordString.getBytes()), fileName);
} catch (Exception e) {
return null;
}
}
