Java 将DOCX转换为包含图像的HTML
我正在使用DOCX4J将DOCX转换为HTML。我已成功完成转换并获得HTML格式。我将使用HTML格式将其嵌入电子邮件正文以发送电子邮件。但我有一些问题，如下所示Java 将DOCX转换为包含图像的HTML,java,html,docx,docx4j,Java,Html,Docx,Docx4j,我正在使用DOCX4J将DOCX转换为HTML。我已成功完成转换并获得HTML格式。我将使用HTML格式将其嵌入电子邮件正文以发送电子邮件。但我有一些问题，如下所示 无法在电子邮件正文中显示图像 失去空间和子弹 请找到我写的代码 WordprocessingMLPackage wordMLPackage; wordMLPackage = Docx4J.load(new java.io.File(resourcePath2)); HTMLSettings htmlSettings = Docx4J
WordprocessingMLPackage wordMLPackage;
wordMLPackage = Docx4J.load(new java.io.File(resourcePath2));
HTMLSettings htmlSettings = Docx4J.createHTMLSettings();
htmlSettings.setImageDirPath(imageFolder + resourcePath2 + "_files");
htmlSettings.setImageTargetUri(imageFolder +resourcePath2.substring(resourcePath2.lastIndexOf("/")+1) + "_files");
htmlSettings.setWmlPackage(wordMLPackage);
OutputStream os;
os = new ByteArrayOutputStream();
Docx4jProperties.setProperty("docx4j.Convert.Out.HTML.OutputMethodXML", true);
Docx4J.toHTML(htmlSettings, os, Docx4J.FLAG_SAVE_FLAT_XML);
DOCX = ((ByteArrayOutputStream)os).toString();
对于要在电子邮件正文中工作的图像，我想您需要使用数据URI或将其发布到web可访问的位置 无论哪种情况，您都需要编写以下内容的实现：
public interface ConversionImageHandler {
/**
* @param picture
* @param relationship of the image
* @param part of the image, if it is an internal image, otherwise null
* @return uri for the image we've saved, or null
* @throws Docx4JException this exception will be logged, but not propagated
*/
public String handleImage(AbstractWordXmlPicture picture, Relationship relationship, BinaryPart part) throws Docx4JException;
}
您可以查看docx4j源代码中的一些现有实现，并利用AbstractConversionImageHandler中的helper方法（如createEncodedImage，如果您需要数据URI）。对于要在电子邮件正文中工作的图像，我想您需要使用数据URI或将其发布到web可访问的位置 无论哪种情况，您都需要编写以下内容的实现：

为什么不将docx附加到电子邮件中？我们的用户不希望将其作为附件，他们需要整个docx放在电子邮件正文中。空格和项目符号可能需要是单独的问题，例如OpenXML没有按您的预期处理。为什么不将docx附加到电子邮件中？我们的用户不希望将其作为附件，他们需要电子邮件正文中的整个DOCX。空格和项目符号可能需要是单独的问题，其中OpenXML的处理方式可能与您预期的不同。apache group的官方xwpf转换器在哪里？apache group的官方xwpf转换器在哪里？
