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;
	}
}
