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

/** -----------------------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
    }
