XLSTransformer生成excel文件

jxls的使用方法：

1）声明一个XLSTransformer对象，生成方式就是使用new操作符

                XLSTransformer transformer = new XLSTransformer();

2）得到Template的FIle：

                 String xlsTemplateFileName = this.getClass().getClassLoader().getResource("template.xls");

3）利用XLSTransformer的类的方法生成Excel文件

                  String xlsFileName = "D:"+File.separator+"resule.xls";

                  Map map= new HashMap();

                  map .put("news1","news1 ");

                  map .put("news2","news2");

                  transformer.transformXLS(xlsTemplateFileName , map, xlsFileName);

XLSTransformer类的transformXLS方法的定义如下：

                  public void transformXLS(String srcFilePath, Map  map , String destFilePath) throws ParsePropertyException,

IOException其中：srcFilePath：是Template文件的全文件名（包含路径）

                  map ：需要传入Excel里面的一个Map，jxls根据Template里面的定义和Map里面的对象对Template进行解析，

将Map里面的对象值填入到Excel文件中

                  destFilePath：需要生成的Excel文件的全文件名（包含路径）

Struts.xml配置

<action name="reportTest" method="reportTest"
			class="org.bkgd.tpmis.report.web.action.T">
			<result type="stream">
				<param name="contentType">application/octet-stream</param>
				<param name="inputName">inputStream</param>
				<param name="contentDisposition">attachment;filename="reportTest.xls"</param>
				<param name="bufferSize">4096</param>
			</result>
		</action>

java代码

public class T {

	private InputStream inputStream;

	public String reportTest() {
		try {
			List<Map<String, Object>> list = new ArrayList<Map<String, Object>>();
			Map<String, Object> m1 = new HashMap<String,Object>();
			m1.put("PRONAME", "项目1");
			m1.put("PLANTYPE", "计划1");
			m1.put("PROTYPE", "类别1");
			Map<String, Object> m2 = new HashMap<String,Object>();
			m2.put("PRONAME", "项目2");
			m2.put("PLANTYPE", "计划2");
			m2.put("PROTYPE", "类别2");

			list.add(m1);
			list.add(m2);

			//------------------------开始报表
			Map<String, Object> para = new HashMap<String, Object>();
			para.put("result", list);
			XLSTransformer transformer = new XLSTransformer();
			Workbook wb;
			try {
				//模板路径
				String classPath =  this.getClass().getClassLoader().getResource("report/resource/reportTest.xls").getPath();
				//真实导出路径
				String classPath2 =  this.getClass().getClassLoader().getResource("report/temp/reportTest.xls").getPath();
				transformer.transformXLS(classPath, para,classPath2);  //在classPath2下生成excel文件
				inputStream = new FileInputStream(new File(classPath2));
				wb = transformer.transformXLS(new FileInputStream(classPath),para);   //获得Workbook对象

				wb.write(new FileOutputStream(classPath2));  //导出Excel
			} catch (Exception e) {
				throw new ReportException(e);
			}
		} catch (Exception e) {
			e.printStackTrace();
		}
		return "success";
	}

	public InputStream getInputStream() {
		return inputStream;
	}

	public void setInputStream(InputStream inputStream) {
		this.inputStream = inputStream;
	}
}
