Excel解析与数据生成(支持JXL,POI)

最近项目中需要用到Excel解析与生成Excel，但现有系统中没有进行解析工具封装于是便封装一个Excel工具包,支持JXL工具包与POI工具包解析与生成数据，POI支持2003与2007。

Excel解析目前网上有JXL与POI两个类库，相比较下JXL功能较少点 比较容易上手。POI功能更强大，支持2003与2007 。目前POI 3.8 版本中提供SXSSFWorkbook类支持大数据量操作 能够避免内存溢出(目前工具包中暂未使用SXSSFWorkbook的例子)。

工具包中用到第三方包有:

cglib-nodep-2.1_3.jar (用于Excel解析时生成BeanMap对象)
commons-lang3-3.1.jar

jxl.jar（jxl工具包）

以下都是POI解析用到的包，如果只是使用2003可以导入少点包
dom4j-1.6.1.jar
org.apache.poi-osgi-3.8.jar
poi-ooxml-3.8-beta5.jar
poi-ooxml-schemas-3.8-beta5.jar
xmlbeans-2.5.0.jar

工具包生成与解析Excel主要依赖于反射与注解，包中申明一个ExcelAnnotation，该注解注释与需要导出字段上，用于申明标题头。生成Excel时根据判断对象是否使用该注解，然后生成Excel。解析时也根据注解进行解析。

使用注解 注解与需要生成Excel对象上

public class Excel {

	@ExcelAnnotation("名称")
	public String bookName;

	@ExcelAnnotation("行数")
	public int rows;

	@ExcelAnnotation("创建时间")
	public Date createTime;
	
	@ExcelAnnotation("内容")
	public Date content;

	
	public Date getContent() {
		return content;
	}

	public void setContent(Date content) {
		this.content = content;
	}

	public String getBookName() {
		return bookName;
	}

	public void setBookName(String bookName) {
		this.bookName = bookName;
	}

	public int getRows() {
		return rows;
	}

	public void setRows(int rows) {
		this.rows = rows;
	}

	public Date getCreateTime() {
		return createTime;
	}

	public void setCreateTime(Date createTime) {
		this.createTime = createTime;
	}

	@Override
	public String toString() {
		StringBuffer buffer = new StringBuffer();
		buffer.append("{[bookName : " + (null == bookName ? "" : bookName)
				+ "]");
		buffer.append("[rows : " + rows + "]");
		buffer.append("[createTime : "
				+ (null == createTime ? "" : DateTools.format(createTime))
				+ "]}");
		return buffer.toString();
	}

}

JXL生成与解析例子

public class JxlExcelTest {


	/**
	 * 创建Excel
	 */
	public static void testCreateWorkbook() {
		try {
			OutputStream os = new FileOutputStream("e://excel//jxlExcel.xls");
			List<Object> allExcel = new ArrayList<Object>(10);

			// 创建对象存放数据
			for(int i = 0 ; i<10000; i ++){
				Excel excel4 = new Excel();
				excel4.setBookName("excel"+i);
				excel4.setCreateTime(new Date());
				excel4.setRows(i);
				allExcel.add(excel4);
			}
			
			WritableWorkbook book = JxlUtil.createWorkbook("excel23",
						Excel.class, allExcel, os);
			
			book.write();
			book.close();

		} catch (FileNotFoundException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (RowsExceededException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (WriteException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IllegalArgumentException e) {
			// TODO Auto-generated catch block

		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IllegalAccessException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (InstantiationException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}

	/**
	 * 解析Excel
	 */
	public static void testAnalyticJxlExcel() {

		try {
			InputStream input = new FileInputStream("e://excel//jxlExcel.xls");
			Workbook workBook = Workbook.getWorkbook(input);
			List<Object> list = JxlAnalyticalData.AnalyticJxlExcel(workBook, Excel.class);
			for(Object object : list){
				System.out.println((Excel)object);
			}
		} catch (FileNotFoundException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (BiffException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IllegalArgumentException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IllegalAccessException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (InstantiationException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}
	
	
	/**
	 * @param args
	 */
	public static void main(String[] args) {
		
		long a = System.currentTimeMillis();
		// TODO Auto-generated method stub
		//创建Excle
		testCreateWorkbook();
//		//解析Excel
//		testAnalyticJxlExcel();
		System.out.println("执行耗时 : " + (System.currentTimeMillis() - a)
				/ 1000f + " 秒 ");
		
	}

}

//		OutputStream os = new FileOutputStream("e://excel//poiExcel2007.xlsx");
		List<Object> allExcel = new ArrayList<Object>(10000);

		// 创建对象存放数据
		for(int i = 0 ; i<10000; i ++){
			Excel excel4 = new Excel();
			excel4.setBookName("excel"+i);

		// 创建2003
		 HSSFWorkbook sr = PoiUtil.createWorkbook("pooi", Excel.class,
