封装jxl的小工具(二) - allenben

更新时间: 2015-05-04 00:00:00 责任编辑: Author_N15

 

 编译Schema:
xjc jxl.xsd -p jxl.jaxb
生成N多文件:
生成的Java文件

生成的Java文件全部放在jxl.jaxb包下。

 

 

然后对Excel类编辑:

@XmlRootElement(name="excel")//添加
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "excel", propOrder = {
    "format",
    "sheet"
})
public class Excel {

    ...

}

 

 

JAXBExcel类:

构造函数:

public JAXBExcel(Source xml, Source xsl) {
	try {
		Transformer trans = TransformerFactory.newInstance()
				.newTransformer(xsl);
		JAXBContext context = JAXBContext.newInstance("jxl.jaxb");
		JAXBResult result = new JAXBResult(context);
		trans.transform(xml, result);
		table = (Excel) result.getResult();
		Marshaller marshaller = context.createMarshaller();
		marshaller.setProperty("jaxb.formatted.output", true);
		marshaller.setProperty("jaxb.encoding", "UTF-8");
		marshaller.marshal(table, System.out);
	} catch (Exception e) {
		e.printStackTrace();
		throw new RuntimeException(e.getMessage());
	}
}

 

 

处理XML文件:

public void process(OutputStream os) throws IOException, WriteException,
		ParseException {
	if (table == null) {
		throw new RuntimeException("The table is not init yet");
	}
	processFormat(table.getFormat());
	WritableWorkbook excel = Workbook.createWorkbook(os);
	Iterator<ExcelSheet> excelSheets = table.getSheet().iterator();
	for (int i = 0; excelSheets.hasNext(); i++) {
		ExcelSheet sheetData = excelSheets.next();
		WritableSheet sheet = excel.createSheet(sheetData.getName(), i);
		// sheet.getSettings().setProtected(true);
		// sheet.getSettings().setPassword("zhaobq");
		// 锁定单元格,设置保护密码
		int row = 0;
		if (sheetData.getHead().getRow().size() > 0) {
			this.setView(sheet, sheetData.getHead().getRow().get(
					sheetData.getHead().getRow().size() - 1));
		}

		row = processTitle(sheetData.getTitle(), sheet, row);
		row = processHead(sheetData.getHead(), sheet, row);
		row = processBody(sheetData.getBody(), sheet, row);
		row = processFoot(sheetData.getFoot(), sheet, row);
	}// TABLE
	excel.write();
	excel.close();
}

 

JAXBExcel类中公共的方法就这两个:

首先用XML数据文件和XSL模板文件构造JAXBExcel对象,

 

然后用JAXBExcel.process()得到文件的输出流
