input 就是直接在value身上设置 使用jsp的时候

前端的使用：

<form id="postForm" action="${pageContext.request.contextPath}/uploadSpotImg" method="Post" enctype="multipart/form-data">
			<table>
				<tr>
					标题
				</tr>
				<tr>
				
					<input  type="text" name="sTitle" value="${spot.sTitle} "/ >
				</tr>
				<tr>
					简介
				</tr>
				<tr>
					<input type="text" name="sInfo" value="${spot.sInfo} " / >
				</tr>
				<tr>
					地区
				</tr>
				<tr>
					
					省<input name="rProvince" type="text" value=" ${spot.regionInfo.rProvince}"  />
					市<input name="rCity" type="text" value="${spot.regionInfo.rCity}"  />
					区<input name="rArea" type="text"  value="${spot.regionInfo.rArea}" />
					 详细<input name="rInfo" type="text" value="${spot.regionInfo.rInfo}"  />
				</tr>
				
				<tr>
				图片
				</tr>
				
				<tr>
				<input name="img1" type="file" value="${spot.sImg}" />
				</tr>
				
				<tr>
				<input name="img2" type="file" value="" />
				</tr>
				<tr>
				<input name="img3" type="file" value="" />
				</tr>
				<tr>
				<input id="upload" type="submit" value="提交" />
				</tr>
			</table>
		</form>

 后台的关联：

	@Autowired
	SpotService spotService;
	@Autowired
	RegionInfoService regionInfoService;
	// 景点模块
	@RequestMapping("/spotModule")
	public String spotModule(HttpServletRequest request, HttpServletResponse resp) {
		request.setAttribute("spots", spotService.all());

		return "spotModule";
	}

 给value设置就是直接给赋值
