ueditor实现word文档的导入和下载功能的方法：
1、UEditor没有提供word的导入功能，只能说是粘贴复制。
2、方案：用poi来提供word导入，思路是将word转换为html输出，再用UEditor提供的setContent()方法将html的内容添加到编辑器中。
方案缺点，一是poi对word文本的格式获取必须按setContent()可接受的方式进行；二是我暂时没发现poi可以提供获取段落格式（对齐方式、缩进量）的方法。
代码如下：package demo;
import java.io.BufferedWriter;
import java.io.ByteArrayOutputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;

try {
htmlContent = convert2Html("D://test//1.doc","D://test//1.html");
} catch (Exception e) {
e.printStackTrace();
}
System.out.println(htmlContent);
}

public String savePicture( byte[] content, PictureType pictureType, String suggestedName, float widthInches, float heightInches )
{
return "D:/test/"+suggestedName;

} );

wordToHtmlConverter.processDocument(wordDocument);

//save pictures
List pics = wordDocument.getPicturesTable().getAllPictures();
if( pics!=null ){

System.out.println();

return new String(out.toByteArray());

}

UEditor没有提供word的导入功能，只能说是粘贴复制。

另外的方案：用poi来提供word导入，思路是将word转换为html输出，再用UEditor提供的setContent()方法将html的内容添加到编辑器中。这个方案有两个缺点，一是poi对word文本的格式获取必须按setContent()可接受的方式进行；二是我暂时没发现poi可以提供获取段落格式（对齐方式、缩进量）的方法。

可以参考以下代码，这是从网上找的（不记得网页地址了，谢谢代码原主提供）

Answer 3

这个编辑器有几个函数，可以在编辑器加载完后给编辑器赋值。具体你搜一下帮助文档。
ueditor_1_2_0-gbk完整包里面有个_examples文件夹，看哈帮助吧，里面有获得内容、写入内容、判断是否有内容等等函数都有，而且还有示例。
editor.getContent()
editor.setContent()

追问

这只是对编辑器进行的get和set，并不能实现Word文档的导入呢。

1、选中表格；

2、选择表格工具布局选项卡，在对齐方式处，根据需要选择一种即可，如图所示。
