docx4j

如果在使用docx4j的过程中有一些效果自己不会写，上网也没搜索到答案，怎么解决呢？
可以把word 2007解压，word 2007解压后是很多xml,docx4j的sample例子上面有解压word的代码，如下：

import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;

import org.apache.commons.io.IOUtils;
import org.docx4j.openpackaging.exceptions.Docx4JException;
import org.docx4j.openpackaging.io3.Load3;
import org.docx4j.openpackaging.io3.Save;
import org.docx4j.openpackaging.io3.stores.UnzippedPartStore;
import org.docx4j.openpackaging.io3.stores.ZipPartStore;
import org.docx4j.openpackaging.packages.OpcPackage;
import org.docx4j.openpackaging.packages.WordprocessingMLPackage;

public class Word_解压_Unzip_S3_Test {
	public static void main(String[] args) throws Exception {
		Word_解压_Unzip_S3_Test t = new Word_解压_Unzip_S3_Test();
		//t.unzipWord("f:/saveFile/temp/test_t.docx","f:/saveFile/temp/Unzip_3");
		t.unzipWord("f:/saveFile/temp/img_word.docx","f:/saveFile/temp/Unzip_8");
		//t.zipXml("f:/saveFile/temp/Unzip_2", "f:/saveFile/temp/test_t2.docx");
	}

	public void unzipWord(String fileName,String outFilePath) throws Exception {
		WordprocessingMLPackage wordMLPackage = WordprocessingMLPackage
				.load(new java.io.File(fileName));
		File baseDir = new File(outFilePath);
		baseDir.mkdir();
		UnzippedPartStore ups = new UnzippedPartStore(baseDir);
		ups.setSourcePartStore(wordMLPackage.getSourcePartStore());
		Save saver = new Save(wordMLPackage, ups);
		saver.save(null);
	}

	public void zipXml(String inputfilepath, String outFilePath)
			throws Exception {
		System.out.println(inputfilepath);

		// Load the docx
		File baseDir = new File(inputfilepath);
		UnzippedPartStore partLoader = new UnzippedPartStore(baseDir);
		final Load3 loader = new Load3(partLoader);
		OpcPackage opc = loader.get();

		// Save it zipped
		ZipPartStore zps = new ZipPartStore();
		zps.setSourcePartStore(opc.getSourcePartStore());
		Save saver = new Save(opc, zps);
		FileOutputStream fos = null;
		try {
			fos = new FileOutputStream(new File(outFilePath));
			saver.save(fos);
		} catch (FileNotFoundException e) {
			throw new Docx4JException("Couldn't save " + outFilePath, e);
		} finally {
			IOUtils.closeQuietly(fos);
		}
	}
}

里面的内容为：

       和excel 2007解压的内容差不多。

       word内容在document.xml,页眉页脚在header.xml和footer.xml中，想要什么效果粗暴点就是把xml内容替换掉，后面会讲到这方面的内容，也可以这样做，先把原word解压一份，在word上面添加自己想要的效果，在解压,对比2份文件对应的xml内容就知道要修改那些类了，如下：


      想要好看点就先格式化xml,如下：

图中就是设置页眉底部的边框xml代码部分,位置在p-->ppr->pbdr下面,名字叫between,相应的代码可以这么写:

P p = factory.createP();
PPr pPr = p.getPPr();
if (pPr == null) {
	pPr = factory.createPPr();
}
PBdr pBdr=pPr.getPBdr();
if(pBdr==null){
	pBdr=factory.createPPrBasePBdr();
}
CTBorder value=new CTBorder();
value.setVal(STBorder.SINGLE);
value.setColor("000000");
value.setSpace(new BigInteger("0"));
value.setSz(new BigInteger("3"));
pBdr.setBetween(value);
pPr.setPBdr(pBdr);

setBetween的时候就知道里面是什么类型的变量了,其他的差不多也可以这么做。

在使用docx4j的过程中，有种感觉就是docx4j其实是在拼xml，再压缩为word,有种自己替换变量制作word的冲动，这个想法已经有人写过了，他的做法如下，

1)制作一份模版word,变量名用${}括起来

2)解压word为xml,替换xml内容，再压缩为word

代码如下:

//例子来自Github,原地址忘了,代码被我改过一部分

	public static void main(String[] args) {
		DocxTemplater templater = new DocxTemplater("f:/saveFile/temp/test_c");
		File f = new File(
				"f:/saveFile/temp/doc_template.docx");
		HashMap<String, Object> map = new HashMap<String, Object>();
		map.put("TITLE", "这是替换后的文档");
		map.put("XUHAO", "1");
		map.put("NAME", "梅花");
		map.put("NAME2", "杏花");
		map.put("WORD", "问世间情为何物");
		map.put("DATA", "2014-9-28");
		map.put("BOSS", "Github");
		templater.process(f, map);
	}
}

效果如下：

      缺点:页眉页尾没替换，除非自己替换header.xml和footer.xml中的变量,对表格无效，想要替换变量制作表格，可以搜索下iteye的博文，以前有哥们写过，其实就是拿到table，然后自己往里面塞数据。
     全文完。
