这篇文章给大家介绍docx 格式的word 文档，即加密的word文档。它是采用原生的xml模版，生成word文档，此word 文档的格式是offi2007以上版本。

一、首先制作生成模版，先本地新建一个docx格式的word文档，然后把 .docx改成 .zip ，如图所示：

二、双击zip文件，出现下图所示；然后单击word文件夹，找到document.xml 文件，复制出来。这就是原生的xml模板，打开此xml文件，编辑里面的参数，参数编写和上一篇文章一样，可以参考一下

模板微调后举例如下：

三、下面给大家上测试代码，如下：

import java.io.BufferedWriter;
    import java.io.File;
    import java.io.FileInputStream;
    import java.io.FileOutputStream;
    import java.io.IOException;
    import java.io.InputStream;
    import java.io.OutputStream;
    import java.io.OutputStreamWriter;
    import java.io.Writer;
    import java.util.HashMap;
    import java.util.Map;
    import java.util.zip.ZipEntry;
    import java.util.zip.ZipInputStream;
    import java.util.zip.ZipOutputStream;
    import freemarker.template.Configuration;
    import freemarker.template.Template;
    
    /**

    */
    public class BoKeWordDocx {  
        
       public static void main(String[] args) throws Exception {  
           freemarkerDocxTest( );
       }  
       
    	 public static String freemarkerDocxTest( ) throws Exception{
    	     Configuration configuration = new Configuration();
    	     //data.xml的生成路径
    	     String fileDirectory = "E://template/";
    	     configuration.setDirectoryForTemplateLoading(new File(fileDirectory));
    	     Template template = configuration.getTemplate("document.xml");
    	     Map<String,String> dataMap = new HashMap<>();
    	     dataMap.put("fullName"," 南道");
    	     dataMap.put("number","20");
    	     dataMap.put("language","java,php");
    	     dataMap.put("example","Hello World!");
    
    	     /** 指定输出word文件的路径 **/
    	     String outFilePath = "E://template/data.xml";
    	     File docFile = new File(outFilePath);
    	     FileOutputStream fos = new FileOutputStream(docFile);
    	     OutputStreamWriter oWriter = new OutputStreamWriter(fos);
    	     Writer out = new BufferedWriter(new OutputStreamWriter(fos),10240);
    	     template.process(dataMap,out);
    
    	     if(out != null){
    	         out.close();
    	     }
    	    //以下代码 主要用来加密已经生成的xml文件，把xml文件正式转换成加密的word文档
    	     // 包装输入流
    	     ZipInputStream zipInputStream =  wrapZipInputStream(new FileInputStream(new File("E://template/default.zip")));
    	     //包装输出流
    	     ZipOutputStream zipOutputStream =  wrapZipOutputStream(new FileOutputStream(new File("E://template/default.docx")));
    	     String itemname = "word/document.xml";
    	     //正式加密替换成docx格式文档
    	     replaceItem(zipInputStream, zipOutputStream, itemname, new FileInputStream(new File("E://template/data.xml")));
    	     System.out.println("加密成功！");
    	   
    	     return null;
       }
       
    	    public static ZipInputStream wrapZipInputStream(InputStream inputStream){
    	        ZipInputStream zipInputStream = new ZipInputStream(inputStream);
    	        return zipInputStream;
    	    }
    	    
    	    public static ZipOutputStream wrapZipOutputStream(OutputStream outputStream){
    	        ZipOutputStream zipOutputStream = new ZipOutputStream(outputStream);
    	        return zipOutputStream;
    	    }
    	    
    	    public static void replaceItem(ZipInputStream zipInputStream,ZipOutputStream zipOutputStream, String itemName,InputStream itemInputStream){
    			if(null == zipInputStream){return;}
    			if(null == zipOutputStream){return;}
    			if(null == itemName){return;}
    			if(null == itemInputStream){return;}
    			ZipEntry entryIn;
    				try {
    				while((entryIn = zipInputStream.getNextEntry())!=null){
    					String entryName =  entryIn.getName();
    					ZipEntry entryOut = new ZipEntry(entryName);
    					// 只使用 name
    					zipOutputStream.putNextEntry(entryOut);
    					// 缓冲区
    					byte [] buf = new byte[8*1024];
    					int len;
    					
    					if(entryName.equals(itemName)){
    						 // 使用替换流
    						 while((len = (itemInputStream.read(buf))) > 0) {
    						     zipOutputStream.write(buf, 0, len);
    						 }
    					} else {
    						 // 输出普通Zip流
    						 while((len = (zipInputStream.read(buf))) > 0) {
    						     zipOutputStream.write(buf, 0, len);
    						 }
    					}
    					// 关闭此 entry
    					zipOutputStream.closeEntry();
    				
    				}
    			} catch (IOException e) {
    			    e.printStackTrace();
    			}finally {
    				//e.printStackTrace();
    				close(itemInputStream);
    				close(zipInputStream);
    				close(zipOutputStream);
    			}
    			}
    
    	    private static void close(InputStream inputStream){
    	        if (null != inputStream){
    	            try {
    	                inputStream.close();
    	            } catch (IOException e) {
    	                e.printStackTrace();
    	            }
    	        }
    	    }
    
    	    private static void close(OutputStream outputStream){
    	        if (null != outputStream){
    	            try {
    	                outputStream.flush();
    	                outputStream.close();
    	            } catch (IOException e) {
    	                e.printStackTrace();
    	            }
    	        }
    	    }
    }

四、此代码亲测有效，加密方法是我在网上找的，微调了一下，可以用。再此基础上大家可以继续优化。怎样证明此文档是加密的呢？用notepad 打开如下图所示：

五、次加密文档适用于offic2007以上版本。大家应该注意到生成此文档的技术依然是当前流行的freemarker技术，下篇文章我们将介绍用POI技术实现word文档的生成。敬请关注！！！如有疑问，大家留言，一定帮大家及时解决！
