jsf Hssf 創建并下載 M$ Excel

在jsf中通過FacesContext訪問上下文；
Hssf通過 HSSFWorkbook 向輸出流寫入；
具體代碼：

Bean：

public class TestBean {

public String action() {

HSSFWorkbook wb = new HSSFWorkbook();

FacesContext context=FacesContext.getCurrentInstance();

HttpServletResponse response = (HttpServletResponse) context.getExternalContext().getResponse();

response.reset();

response.setContentType("application/ms-excel");

try {

response.setHeader("Content-disposition", "attachment;filename="+new String("下載Excel.xls".getBytes(),"iso-8859-1"));

wb.write(response.getOutputStream());

} catch (Exception e1) {

// TODO Auto-generated catch block

e1.printStackTrace();

}

FacesContext.getCurrentInstance().responseComplete();

return null;

}

以上只是一個空的簡單的Excel 具體怎么創建符合項目要求的參看：HSSF GUIDE！
faces-config.xml:

<managed-bean>

<managed-bean-name>test</managed-bean-name>

<managed-bean-class>yds.study.web.TestBean</managed-bean-class>

<managed-bean-scope>session</managed-bean-scope>

</managed-bean>

jsp：

<f:view>

<h:form>

<h:commandButton id="button" value="下載" rendered="true"

action="#{test123.action}" />

</h:form>

</f:view>

ok這樣就可以了;)
