SSM整合上传下载之添加商品

上传下载细节：

导入xml配置文件！！

Controller中要配置存储路径,调用transferto上传文件

上传图片要将图片的类设置为 MultipartFile

图片下载：

源码：

源码:

一、建表：

 1 DROP TABLE IF EXISTS `t_house`;
 2 CREATE TABLE `t_house` (
 3   `h_id` int(11) NOT NULL AUTO_INCREMENT,
 4   `h_name` varchar(64) NOT NULL,
 5   `h_rect` double(10,2) NOT NULL,
 6   `h_date` date NOT NULL,
 7   `h_loc1` varchar(255) NOT NULL,
 8   `h_loc2` varchar(255) NOT NULL,
 9   `h_img` varchar(120) NOT NULL,
10   `h_userId` int(11) NOT NULL,
11   PRIMARY KEY (`h_id`)
12 ) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=utf8;

二、首先注入maven依赖：

pom.xml

 1 <dependency>
 2       <groupId>org.projectlombok</groupId>
 3       <artifactId>lombok</artifactId>
 4       <version>1.18.4</version>
 5       <scope>provided</scope>
 6     </dependency>
 7     <!--文件上传下载 -->
 8     <dependency>
 9       <groupId>commons-io</groupId>
10       <artifactId>commons-io</artifactId>
11       <version>2.4</version>
12     </dependency>
13     <!--用来帮助进行IO功能开发 -->
14     <dependency>
15       <groupId>commons-fileupload</groupId>
16       <artifactId>commons-fileupload</artifactId>
17       <version>1.3</version>
18     </dependency>

三、添加配置：

springmvc.xml

1 <!-- 多部分文件上传 M kb byte-->
2     <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
3         <property name="maxUploadSize" value="104857600"/>
4         <property name="defaultEncoding" value="UTF-8"></property>
5     </bean>

四、编辑插入语句：

 1 <?xml version="1.0" encoding="UTF-8" ?>
 2 <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
 3 <mapper namespace="com.etc.dao.HouseDAO">
 4     <insert id="add">
 5  INSERT INTO `t_house` (
 6     `h_name`,
 7     `h_rect`,
 8     `h_date`,
 9     `h_loc1`,
10     `h_loc2`,
11     `h_img`,
12     `h_userId`
13 )
14 VALUES
15     (
16         #{hName},
17         #{hRect},
18         #{hDate},
19         #{hLoc1},
20         #{hLoc2},
21         #{hImg},
22         #{userId}
23     );
24 </insert>
25 
26 
27 </mapper>

五、建立实体类：

HouseVO ：

 1 package com.etc.Vo;
 2 
 3 import lombok.AllArgsConstructor;
 4 import lombok.Data;
 5 import lombok.NoArgsConstructor;
 6 import org.springframework.format.annotation.DateTimeFormat;
 7 import org.springframework.web.multipart.MultipartFile;
 8 
 9 import java.util.Date;
10 
11 @Data
12 @AllArgsConstructor
13 @NoArgsConstructor
14 public class HouseVO {
15     private String title;
16     private Double floorage;
17     @DateTimeFormat(pattern = "yyyy-MM-dd")
18     private Date houseDate;
19     private String districtId;
20     private String streetId;
21     private MultipartFile hImg;
22 }

House ：

 1 package com.etc.entity;
 2 
 3 import lombok.AllArgsConstructor;
 4 import lombok.Data;
 5 import lombok.NoArgsConstructor;
 6 
 7 import java.util.Date;
 8 
 9 @Data
10 @AllArgsConstructor
11 @NoArgsConstructor
12 public class House {
13     private Integer hId;
14     private String hName;
15     private Double hRect;
16     private Date hDate;
17     private String hLoc1;
18     private String hLoc2;
19     private String hImg;
20     private int userId;
21 }

HouseConverter ：

 1 package com.etc.converter;
 2 
 3 import com.etc.Vo.HouseVO;
 4 import com.etc.entity.House;
 5 
 6 public class HouseConverter {
 7     public static House convert(HouseVO houseVO, String img,int id) {
 8         House house = new House();
 9         house.setHName(houseVO.getTitle());
10         house.setHRect(houseVO.getFloorage());
11         house.setHDate(houseVO.getHouseDate());
12         house.setHLoc1(houseVO.getDistrictId());
13         house.setHLoc2(houseVO.getStreetId());
14         house.setHImg(img);
15         house.setUserId(id);
16         return house;
17     }
18 }

六、编写接口：

1 package com.etc.dao;
2 
3 import com.etc.entity.House;
4 
5 public interface HouseDAO {
6 
7     void add(House house);
8 
9 }

七、编写service：

 1 package com.etc.servise;
 2 
 3 import com.etc.dao.HouseDAO;
 4 import com.etc.entity.House;
 5 import org.springframework.beans.factory.annotation.Autowired;
 6 import org.springframework.stereotype.Service;
 7 
 8 @Service
 9 public class HouseService {
10 
11     @Autowired
12     private HouseDAO houseDAO;
13 
14     public void add(House house){
15         houseDAO.add(house);
16     }
17 
18 
19 }

八、编写控制层：

 1 package com.etc.controller;
 2 
 3 import com.etc.Vo.HouseSearchVO;
 4 import com.etc.Vo.HouseVO;
 5 import com.etc.common.Constant;
 6 import com.etc.converter.HouseConverter;
 7 import com.etc.entity.House;
 8 import com.etc.entity.HouseSearch;
 9 import com.etc.entity.User;
10 import com.etc.servise.HouseService;
11 import com.github.pagehelper.PageHelper;
12 import com.github.pagehelper.PageInfo;
13 import org.apache.commons.io.IOUtils;
14 import org.springframework.beans.factory.annotation.Autowired;
15 import org.springframework.stereotype.Controller;
16 import org.springframework.ui.Model;
17 import org.springframework.util.StringUtils;
18 import org.springframework.web.bind.annotation.ModelAttribute;
19 import org.springframework.web.bind.annotation.RequestMapping;
20 
21 import javax.servlet.http.HttpServletResponse;
22 import javax.servlet.http.HttpSession;
23 import java.io.File;
24 import java.io.FileInputStream;
25 import java.io.IOException;
26 import java.util.List;
27 
28 @Controller
29 @RequestMapping("/house")
30 public class HouseController {
31 
32     public static final String UPLOAD_DIR = "D:\images\";
33 
34     @RequestMapping("/images")
35     public String images(String imgName, HttpServletResponse response) throws IOException {
36         //将图片的输入流，复制到response的输出流中，
37         IOUtils.copy(new FileInputStream(UPLOAD_DIR+imgName),response.getOutputStream());
38         return null;
39     }
40 
41 
42     @Autowired
43     private HouseService houseService;
44 
45     @RequestMapping("/add")
46     public String add(HouseVO houseVO, HttpSession session) throws IOException {
47         //获取session中的user对象
48         User user = (User) session.getAttribute("user");
49         //拿到user对象的id
50         int userId = user.getUserId();
51         //设置文件上传的路径
52         houseVO.getHImg().transferTo(new File(UPLOAD_DIR + houseVO.getHImg().getOriginalFilename()));
53         //建立house对象
54         House house = HouseConverter.convert(houseVO, houseVO.getHImg().getOriginalFilename(), userId);
55         //调用添加方法
56         houseService.add(house);
57         return "list";
58     }
