word模板生成word文档并下载

控制层：

public void downpact() {
String str=request.getParameter("dId");
String docPath = request.getServletContext().getRealPath("/") + "template";
EmploeeContract emploeeContract=emploeeContractService.get(Long.parseLong(str));
emploeeContractService.downpact(request,response,emploeeContract,docPath);
