文件上传
这个文件上传重写了 HttpRequest,不讲费话直接写方法和代码了,对了，还有两个包不要忘记引入 1.commons-io-1.3.2.jar 2.commons-io-1.3.2.jar
前台页面：index.jsp

保存：save.java 直接写的方法
View Code
/** -----------------------保存数据---------------------------------------------- */ /* 招飞初检保存 */ @RequestMapping(params = "method=physicalInitSave", method = RequestMethod.POST) //这个可以不要，是spring注解 public String physicalInitSave(HttpServletRequest request) { request = new MulpartRequestWrapper(request); //引入重写request的实体类 必须引入 Physical physicals=new Physical(); //实例化一个实体 String comment = request.getParameter("comment"); //从request 上获得内容 如：<input id="comment" name="comment" type="text"> physicals.setPersonnel(request.toString()); //request.toString() 就是文件上传的地址 physicalBO.save(physicals); //保存实体 return "physical/physicalInit"; //只是一个返回值 aa也一样 }
文件上传：MulpartRequestWrapper.java 注：本文件不用修改 直接贴过去就行了
