需求分析
在商品录入界面实现多图片上传
当用户点击新建按钮，弹出上传窗口
后端代码（maven项目）
工具类
（1）common工程pom.xml引入依赖
<!-- 文件上传组件 -->
<dependency>
<groupId>org.csource.fastdfs</groupId>
<artifactId>fastdfs</artifactId>
</dependency>
<dependency>
<groupId>commons-fileupload</groupId>
<artifactId>commons-fileupload</artifactId>
</dependency>
（2）将fastDFS工具类FastDFSClient.java 拷贝到common工程(代码在最下面)
配置文件
（1）将fastDFS配置文件 fdfs_client.conf 拷贝到shop-web工程config文件夹（最下面）
（2）在shop-web工程application.properties添加配置(fastDFS服务器地址)
FILE_SERVER_URL=http://192.168.25.153/
（3）在shop-web工程springmvc.xml添加配置
<!-- 配置多媒体解析器 -->
<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<property name="defaultEncoding" value="UTF-8"></property>
<!-- 设定文件上传的最大值5MB，5*1024*1024(大小自己定义) -->
<property name="maxUploadSize" value="5242880"></property>
</bean>
控制层
在shop-web新建UploadController.java
package com.pinyougou.shop.controller;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.multipart.MultipartFile;
import entity.Result;
import util.FastDFSClient;
/**
* 文件上传Controller
* @author Administrator
*
*/
@RestController
public class UploadController {
@Value("${FILE_SERVER_URL}")
private String FILE_SERVER_URL;//文件服务器地址
@RequestMapping("/upload")
public Result upload( MultipartFile file){
//1、取文件的扩展名
String originalFilename = file.getOriginalFilename();
String extName = originalFilename.substring(originalFilename.lastIndexOf(".") + 1);
try {
//2、创建一个 FastDFS 的客户端
FastDFSClient fastDFSClient = new FastDFSClient("classpath:config/fdfs_client.conf");
//3、执行上传处理
String path = fastDFSClient.uploadFile(file.getBytes(), extName);
//4、拼接返回的 url 和 ip 地址，拼装成完整的 url
String url = FILE_SERVER_URL + path;
return new Result(true,url);
} catch (Exception e) {
e.printStackTrace();
return new Result(false, "上传失败");
}
}
}
前端代码
1 服务层
（1）在shop-web工程创建uploadService.js
//文件上传服务层
app.service("uploadService",function($http){
this.uploadFile=function(){
var formData=new FormData();//是HTML5中新增的一个类，专门用于文件上传
formData.append("file",file.files[0]); //file代表文件上传框的name，.files[0]代表取页面的第一个文件上传框
return $http({ //angularjs的另一种写法
method:'POST',
url:"../upload.do",
data: formData, //formData作为载体上传文件
headers: {'Content-Type':undefined}, //头信息设置为不指定类型，默认是json
transformRequest: angular.identity //表示对整个表单进行二进制序列化
});
}
});
anjularjs对于post和get请求默认的Content-Type header 是application/json。通过设置‘Content-Type’: undefined，这样浏览器会帮我们把Content-Type 设置为 multipart/form-data.
通过设置 transformRequest: angular.identity ，anjularjs transformRequest function 将序列化我们的formdata object.
（2）将uploadService服务注入到goodsController 中
//商品控制层（商家后台）
app.controller('goodsController' ,function($scope,$controller ,goodsService,itemCatService,uploadService){
（3）在goods_edit.html引入js
<script type="text/javascript" src="../js/base.js"> </script>
<script type="text/javascript" src="../js/service/goodsService.js"> </script>
<script type="text/javascript" src="../js/service/itemCatService.js"> </script>
<script type="text/javascript" src="../js/service/uploadService.js"> </script>
<script type="text/javascript" src="../js/controller/baseController.js"> </script>
<script type="text/javascript" src="../js/controller/goodsController.js"> </script>
上传图片
（1）goodsController编写代码
/**
* 上传图片
*/
$scope.uploadFile=function(){
uploadService.uploadFile().success(
function(response) {
if(response.success){//如果上传成功，取出url
$scope.image_entity.url=response.message;//设置文件地址
}else{
alert(response.message);
}
}).error(function() {
alert("上传发生错误");
});
};
（2）在HTML中修改图片上传窗口，调用上传方法，回显上传图片
<div class="modal-body">
<table class="table table-bordered table-striped">
<tr>
<td>颜色</td>
<td><input class="form-control" placeholder="颜色" ng-model="image_entity.color"> </td>
</tr>
<tr>
<td>商品图片</td>
<td>
<table>
<tr>
<td>
<input type="file" id="file" />
<button class="btn btn-primary" type="button" ng-click="uploadFile()">
上传
</button>
</td>
<td>
<img src="{{image_entity.url}}" width="200px" height="200px">
</td>
</tr>
</table>
</td>
</tr>
</table>
</div>
（3）修改新建按钮(初始化清空数据)
<button type="button" class="btn btn-default" title="新建" data-target="#uploadModal" data-toggle="modal" ng-click="image_entity={}" ><i class="fa fa-file-o"></i> 新建</button>
告一段落并测试
追加显示图片列表
（1）在goodsController.js增加方法
$scope.entity={goods:{},goodsDesc:{itemImages:[]}};//定义页面实体结构
//添加图片列表
$scope.add_image_entity=function(){
$scope.entity.goodsDesc.itemImages.push($scope.image_entity);
}
（2）修改上传窗口的保存按钮
3 图片列表
（1）在goodsController.js增加方法
$scope.entity={goods:{},goodsDesc:{itemImages:[]}};//定义页面实体结构
//添加图片列表
$scope.add_image_entity=function(){
$scope.entity.goodsDesc.itemImages.push($scope.image_entity);
}
<button class="btn btn-success" ng-click="add_image_entity()" data-dismiss="modal" aria-hidden="true">保存</button>
（3）遍历图片列表
<tr ng-repeat="pojo in entity.goodsDesc.itemImages">
<td>{{pojo.color}}</td>
<td><img alt="" src="{{pojo.url}}" width="100px" height="100px"></td>
<td><button type="button" class="btn btn-default" title="删除" ><i class="fa fa-trash-o"></i> 删除</button></td>
</tr>
移除图片
在goodsController.js增加代码
//列表中移除图片
$scope.remove_image_entity=function(index){
$scope.entity.goodsDesc.itemImages.splice(index,1);
}
修改列表中的删除按钮
<button type="button" class="btn btn-default" title="删除" ng-click="remove_image_entity($index)"><i class="fa fa-trash-o"></i> 删除</button>
上代码
shop-web项目结构如下，common是单独一项目，引入common子项目的依赖即可
