新增房源：
前端的图片上传插件使用的百度的upload。
打开网址：www.qiniu.com
注册账号：然后打开自己的秘钥：
这里的maven依赖，我在一开始就已经都贴出来了，这里只是告诉大家的依赖是什么。
<!-- 七牛依赖 -->
<dependency>
<groupId>com.qiniu</groupId>
<artifactId>qiniu-java-sdk</artifactId>
<version>[7.2.0, 7.2.99]</version>
</dependency>现在我把几个html放进去：

house-add.html:
首先首先springBoot的本地上传方式：
结构如图：新建一个package:images留放上传图片，一个WebFileUploadConfig图片配置类
WebFileUploadConfig：package liangliang.bigdata.config;
import org.springframework.boot.autoconfigure.condition.ConditionalOnClass;
import org.springframework.boot.autoconfigure.condition.ConditionalOnMissingBean;
import org.springframework.boot.autoconfigure.condition.ConditionalOnProperty;
import org.springframework.boot.autoconfigure.web.MultipartProperties;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.multipart.MultipartResolver;
import org.springframework.web.multipart.support.StandardServletMultipartResolver;
import org.springframework.web.servlet.DispatcherServlet;
import javax.servlet.MultipartConfigElement;
import javax.servlet.Servlet;
/**
* 文件上传配置
*/
@Configuration
@ConditionalOnClass({Servlet.class,StandardServletMultipartResolver.class,
MultipartConfigElement.class
})
@ConditionalOnProperty(prefix="spring.http.multipart",name = "enabled", matchIfMissing = true)
//允许springBoot帮我自动配置的一些属性
@EnableConfigurationProperties(MultipartProperties.class)
public class WebFileUploadConfig {
private final MultipartProperties multipartProperties;
//注入属性配置
public WebFileUploadConfig (MultipartProperties multipartProperties){
this.multipartProperties = multipartProperties;
}
@Bean
@ConditionalOnMissingBean
public MultipartConfigElement multipartConfigElement(){
return this.multipartProperties.createMultipartConfig();
}
/**
*注册一个解析器
*/
@Bean(name = DispatcherServlet.MULTIPART_RESOLVER_BEAN_NAME)
@ConditionalOnMissingBean(MultipartResolver.class)
public StandardServletMultipartResolver multipartResolver(){
StandardServletMultipartResolver multipartResolver = new StandardServletMultipartResolver();
multipartResolver.setResolveLazily(this.multipartProperties.isResolveLazily());
return multipartResolver;
}
}
更新后的AdminController：有图片上传的路由
package liangliang.bigdata.web.controller.admin;
import liangliang.bigdata.base.ApiResponse;
import org.springframework.http.MediaType;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.multipart.MultipartFile;
import java.io.File;
import java.io.IOException;
@Controller
public class AdminController {
/**
* 后台管理中心
* @return
*/
@GetMapping("/admin/center")
public String adminCenterPage() {
return "admin/center";
}
/**
* 欢迎页
* @return
*/
@GetMapping("/admin/welcome")
public String welcomePage() {
return "admin/welcome";
}
/**
* 管理员登录页
* @return
*/
@GetMapping("/admin/login")
public String adminLoginPage() {
return "admin/login";
}
/**
*添加房源
*/
@GetMapping("/admin/add/house")
public String addHousePage() {
return "admin/house-add";
}
/**
* 上传图片
*/
@PostMapping(value = "admin/upload/photo",consumes = MediaType.MULTIPART_FORM_DATA_VALUE)
@ResponseBody
public ApiResponse uploadPhoto(@RequestParam("file")MultipartFile file){
if (file.isEmpty()){
//如果为空则给出无效参数
return ApiResponse.ofStatus(ApiResponse.Status.NOT_VALID_PARAM);
}
String fileName = file.getOriginalFilename();
File target = new File("D:\\com7dayshare\\images\\"+fileName);
try {
file.transferTo(target);
} catch (IOException e) {
e.printStackTrace();
return ApiResponse.ofStatus(ApiResponse.Status.INTERNAL_SERVER_ERROR);
}
return ApiResponse.ofSuccess(null);
}
}
更新后的application-dev.properties：增加了图片路径的配置
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://39.107.77.240:3306/xunwu?useUnicode=true&characterEncoding=utf-8
spring.datasource.username=你的账号名字
spring.datasource.password=你的账号密码
#thymeleaf
#在dev的环境下我们禁止它进行自动缓存，否则修改后不能立即看到效果
spring.thymeleaf.cache=false
#multipart config
spring.http.multipart.enabled=true
#测试本地的图片路径
spring.http.multipart.location=D:\\com7dayshare\\images\\
spring.http.multipart.file-size-threshold=5MB
#最大请求的大小
spring.http.multipart.max-request-size=20MB
现在输入地址访问上传图片测试：http://127.0.0.1:8080/admin/center
点击新增，房源、
选择图片进行上传：
成功后检查刚刚的本地文件夹可有这个图片。如下图可以看到已经成功。
自己创建一个七牛云账号：实名认证，后期图片存放在这个上面。
使用七牛云上传图片：
在config的包下面的WebFileUploadConfig的类中加入七牛云的（机房配置和构建一个七牛上传工具实例以及认证信息，七牛空间管理实例）：
同时上传需要一些七牛云的key：
在个人中心的秘钥管理中可以看见自己的公钥和秘钥。
bucket是自己建立的存储空间的名字。
另外还有域名：如下图所示。
更新后WebFileUploadConfig：package liangliang.bigdata.config;

multipartResolver.setResolveLazily(this.multipartProperties.isResolveLazily());
return multipartResolver;
}

房源信息管理（增、删、改、查）：
新增房源功能开发：
在web中的controller文件夹中新建一个house文件夹，把有关房屋相关的controller，都放在这里面：
HouseController：
package liangliang.bigdata.web.controller.house;
import liangliang.bigdata.base.ApiResponse;
import liangliang.bigdata.service.IUserService;
import liangliang.bigdata.service.ServiceMultiResult;
import liangliang.bigdata.service.house.IAddressService;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import java.util.List;
@Controller
public class HouseController {
@Autowired
private IAddressService addressService;
@Autowired
private IHouseService houseService;
@Autowired
private IUserService userService;
/**

@GetMapping("address/support/cities")
@ResponseBody
public ApiResponse getSupportCities() {
ServiceMultiResult<SupportAddressDTO> result = addressService.findAllCities();
if (result.getResultSize() == 0) {
return ApiResponse.ofStatus(ApiResponse.Status.NOT_FOUND);
}
return ApiResponse.ofSuccess(result.getResult());
}
/**

@GetMapping("address/support/regions")
@ResponseBody
public ApiResponse getSupportRegions(@RequestParam(name = "city_name") String cityEnName) {
ServiceMultiResult<SupportAddressDTO> addressResult = addressService.findAllRegionsByCityName(cityEnName);
if (addressResult.getResult() == null || addressResult.getTotal() < 1) {
return ApiResponse.ofStatus(ApiResponse.Status.NOT_FOUND);
}
return ApiResponse.ofSuccess(addressResult.getResult());
}
/**
* 获取具体城市所支持的地铁线路
* @param cityEnName
* @return
*/
@GetMapping("address/support/subway/line")
@ResponseBody
public ApiResponse getSupportSubwayLine(@RequestParam(name = "city_name") String cityEnName) {
List<SubwayDTO> subways = addressService.findAllSubwayByCity(cityEnName);
if (subways.isEmpty()) {
return ApiResponse.ofStatus(ApiResponse.Status.NOT_FOUND);
}
return ApiResponse.ofSuccess(subways);
}
/**

*/
@GetMapping("address/support/subway/station")
@ResponseBody
public ApiResponse getSupportSubwayStation(@RequestParam(name = "subway_id") Long subwayId) {
List<SubwayStationDTO> stationDTOS = addressService.findAllStationBySubway(subwayId);
if (stationDTOS.isEmpty()) {
return ApiResponse.ofStatus(ApiResponse.Status.NOT_FOUND);
}
return ApiResponse.ofSuccess(stationDTOS);
}
}
在entity中新建一个实体类：SupportAddress
SupportAddress：
package liangliang.bigdata.entity;
import javax.persistence.*;
/**
*
*/
@Entity
@Table(name = "support_address")
public class SupportAddress {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
// 上一级行政单位
@Column(name = "belong_to")
private String belongTo;
@Column(name = "en_name")
private String enName;
@Column(name = "cn_name")
private String cnName;
private String level;
@Column(name = "baidu_map_lng")
private double baiduMapLongitude;
@Column(name = "baidu_map_lat")
private double baiduMapLatitude;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getBelongTo() {
return belongTo;
}
public void setBelongTo(String belongTo) {
this.belongTo = belongTo;
}
public String getEnName() {
return enName;
}
public void setEnName(String enName) {
this.enName = enName;
}
public String getCnName() {
return cnName;
}
public void setCnName(String cnName) {
this.cnName = cnName;
}
public String getLevel() {
return level;
}
public void setLevel(String level) {
this.level = level;
}
public double getBaiduMapLongitude() {
return baiduMapLongitude;
}
public void setBaiduMapLongitude(double baiduMapLongitude) {
this.baiduMapLongitude = baiduMapLongitude;
}
public double getBaiduMapLatitude() {
return baiduMapLatitude;
}
public void setBaiduMapLatitude(double baiduMapLatitude) {
this.baiduMapLatitude = baiduMapLatitude;
}
/**

*/
public enum Level {
CITY("city"),
REGION("region");
private String value;
Level(String value) {
this.value = value;
}
public String getValue() {
return value;
}
public static Level of(String value) {
for (Level level : Level.values()) {
if (level.getValue().equals(value)) {
return level;
}
}
throw new IllegalArgumentException();
}
}
}在service中的文件夹中新建一个ServiceMultiResult的类
ServiceMultiResult：package liangliang.bigdata.service;
import java.util.List;
/**
* 通用多结果Service返回结构
* Created by 瓦力.
*/
public class ServiceMultiResult<T> {
private long total;//数据库总共有多少数据
private List<T> result;
public ServiceMultiResult(long total, List<T> result) {
this.total = total;
this.result = result;
}
public long getTotal() {
return total;
}
public void setTotal(long total) {
this.total = total;
}
public List<T> getResult() {
return result;
}
public void setResult(List<T> result) {
this.result = result;
}
//获取当前结果集
public int getResultSize() {
if (this.result == null) {
return 0;
}
return this.result.size();
}
}
在repository文件夹中新建一个SupportAddressRepository接口：
SupportAddressRepository：package liangliang.bigdata.repository;
import liangliang.bigdata.entity.SupportAddress;
import org.springframework.data.repository.CrudRepository;
import java.util.List;
public interface SupportAddressRepository extends CrudRepository<SupportAddress,Long> {
/**
* 获取所有对应行政级别的信息
*/
List<SupportAddress> findAllByLevel(String level);
SupportAddress findByEnNameAndLevel(String enName, String level);
SupportAddress findByEnNameAndBelongTo(String enName, String belongTo);
List<SupportAddress> findAllByLevelAndBelongTo(String level, String belongTo);
}

里面需要设置一下redi的session会话：
我用的是本地的redis:
在config:中新建一个类：
RedisSessionConfig：package liangliang.bigdata.config;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.session.data.redis.config.annotation.web.http.EnableRedisHttpSession;
/**
* 利用redis保存session会话
*/
@Configuration
@EnableRedisHttpSession(maxInactiveIntervalInSeconds = 86400)
public class RedisSessionConfig {
@Bean
public RedisTemplate<String,String>redisTemplate(RedisConnectionFactory connectionFactory){
return new StringRedisTemplate(connectionFactory);
}
}
并且application.properties中需要设置redis：
这里面使用redis出了版本问题：
直接更换redis为3.0以上就可以！
以上给出的所有东西都是为了新增房源功能的开发需要：避免太多，这篇博客只有新增房源。
