struts 2 如何动态生成一个html文件并下载？
是动态生成，并下载，不是先生成到一个目录再去下载，然后再删除生成的文件。
以下是我的下载文件action；
public class TrainingAttendHistoryExportRegisterAction extends DefaultActionSupport { private static final long serialVersionUID = 6929180904579405855L; private String path; public String getPath() { return path; } public void setPath(String path) { this.path = path; } public InputStream getInputStream() throws Exception { // 根据配置文件inputPath属性值返回一个文件输入流 OutputStreamWriter fw = new OutputStreamWriter(new FileOutputStream("trainingAttendHistoryExportRegister.html"),"big5"); fw.write("<html></html>"+"\r\n"); fw.close(); InputStream is=new FileInputStream("pa");// File reDocFile = new File(ServletActionContext.getServletContext().getRealPath("/")+"test.html"); return ServletActionContext.getServletContext().getResourceAsStream(path); } public String execute() throws Exception { return SUCCESS; }}
