接下来我们使用uniapp+springboot实现一个简单的前后端分离的小项目----个人备忘录系统，适合初学者学习，全文大约5w字，全部免费，以下是详细步骤：
（1）项目可行性分析
（一）技术可行性：
1.uniapp是一个基于Vue.js框架的跨平台开发工具，可以在多个平台上实现一次开发多端运行。它提供了丰富的组件和插件，使得开发变得更加高效。
2.uniapp支持多个主流的移动端平台，如iOS和Android，以及微信小程序、H5等。这意味着你可以通过uniapp开发一个备忘录系统，并在多个平台上发布和使用。
3.Vue.js作为uniapp的底层框架，拥有活跃的开发社区和丰富的生态系统，可以提供大量的资源和支持。
（二）经济可行性：
1.uniapp的开发成本相对较低，因为它使用了一套代码可以覆盖多个平台的开发方式，减少了重复的工作量和开发时间。
2.由于uniapp支持多个主流平台，你可以在不同的平台上发布你的备忘录系统，扩大用户群体，增加潜在的收入来源。
3.uniapp的跨平台特性可以降低维护成本，因为你只需要维护一套代码，而不是针对每个平台都进行独立的开发和维护。
（三）社会可行性：
1.备忘录系统是一个常见且实用的应用，它可以帮助个人记录重要事项、提醒任务等。这种类型的应用在社会中有广泛的需求。
2.通过使用uniapp开发备忘录系统，你可以满足不同用户使用不同平台的需求，提高用户体验和满意度。
3.在移动互联网时代，人们越来越依赖手机和移动应用程序进行工作和生活管理。开发备忘录系统可以满足人们随时随地记录和查看备忘录的需求，符合社会的发展趋势。
（2）需求描述
个人备忘录系统主要有登录、注册、查看所有备忘录、创建新的备忘录、删除备忘录、修改备忘录、根据分类查询已完成或未完成的备忘录。

（5）后端工程
首先打开IDEA，选择创建Spring Initializr，按照以下配置，jdk版本无法选择jdk1.8，先不管，进去以后可以改，具体操作可以看我的另一篇相关的博客
配置spring版本，先选择3.2.0，进入项目后再通过pom文件修改
进入项目后修改pom.xml文件为如下配置，我们在pom中手动修改了jdk版本为1.8，spring为2.7.8，这样兼容性比较好，修改后记得刷新maven
<?xml version="1.0" encoding="UTF-8"?>

然后我们修改resources文件夹下的application.yml，数据库连接修改成你自己的，七牛云的使用可以看我上一篇博客
server:
port: 2023
spring:
datasource:
driver-class-name: ***.mysql.cj.jdbc.Driver
url: jdbc:mysql://localhost:3305/memo?characterEncoding=utf-8&serverTimezone=Asia/Shanghai
username: root
password: 123456
mybatis-plus:
global-config:
db-config:
id-type: auto
# configuration:
# log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
# 打开七牛云，找到密钥管理，把相关信息填写到下面3行
myoss:
a***essKey: yourAK
secretKey: yourSK
bucket: yourbucket
接下来在项目下创建如下几个包：
***mon包：
R.java
在***mon文件下创建 R.java 类，主要用于封装返回给前端的数据：
package ***.example.memohehang.***mon;
import lombok.Data;
import java.io.Serializable;
/**
* 统一返回类型
*/
@Data
public class R implements Serializable
{
private int code; // 200是正常，非200表示异常
private String msg;
private Object data;
public static R su***ess(Object data)
{
return su***ess(200, "操作成功", data);
}
public static R su***ess(int code, String msg, Object data)
{
R r = new R();
r.setCode(code);
r.setMsg(msg);
r.setData(data);
return r;
}
public static R error(int i, String msg)
{
return error(400, msg, null);
}
public static R error(String msg, Object data)
{
return error(400, msg, data);
}
public static R error(int code, String msg, Object data)
{
R r = new R();
r.setCode(code);
r.setMsg(msg);
r.setData(data);
return r;
}
}
config包：
CorsConfig.java
在config包下创建 CorsConfig.java 类，用于解决前端跨域问题，在config.AllowedOrigin中填写你自己的前端端口，一般为8080，或者填 * ,允许所有
package ***.example.memohehang.config;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.filter.CorsFilter;
import org.springframework.web.cors.UrlBasedCorsConfigurationSource;
import org.springframework.web.cors.CorsConfiguration;
//解决前端跨域问题
@Configuration
public class CorsConfig {
@Bean
public CorsFilter corsFilter()
{
UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
CorsConfiguration config = new CorsConfiguration();
config.addAllowedOrigin("http://localhost:8080");
config.addAllowedHeader("*");
config.addAllowedMethod("*");
config.setAllowCredentials(true);
source.registerCorsConfiguration("/**", config);
return new CorsFilter(source);
}
}
domain包：
对应数据库的实体类
Notes.java
这里我们利用jsonformat注解进行时间格式化
package ***.example.memohehang.domain;
import ***.baomidou.mybatisplus.annotation.IdType;
import ***.baomidou.mybatisplus.annotation.TableId;
import ***.fasterxml.jackson.annotation.JsonFormat;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import java.util.Date;
@Data
@AllArgsConstructor
@NoArgsConstructor
public class Notes {
@TableId(value = "id", type = IdType.AUTO)
private Integer id;
private Integer rid;
// 内容
private String detail;
// 截止时间
@JsonFormat(locale = "zh", timezone = "GMT+8", pattern = "yyyy-MM-dd HH:mm:ss")
private Date time;
// 类型
private Integer type;
//图片
private String photo;
// 是否完成 0表示还没有 1表示完成了
private Integer finish;
}
Type.java
package ***.example.memohehang.domain;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
@Data
@AllArgsConstructor
@NoArgsConstructor
public class Type
{
private Integer typeid;
private String type;
}User.java
package ***.example.memohehang.domain;
import lombok.AllArgsConstructor;
import ***.baomidou.mybatisplus.annotation.IdType;
import ***.baomidou.mybatisplus.annotation.TableId;
import lombok.Data;
import lombok.NoArgsConstructor;
@Data
@AllArgsConstructor
@NoArgsConstructor
public class User
{
//主键自增
@TableId(value = "id", type = IdType.AUTO)
private Integer id;
private String username;
private String password;
// 头像
private String avatar;
}
utils包：
PathUtils.java
这是对上传的文件进行重命名，在后面的七牛云相关的service中会用到
package ***.example.memohehang.utils;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.UUID;
//对原始文件名进行修改文件名，并修改存放目录
public class PathUtils
{
public static String generateFilePath(String fileName)
{
//根据日期生成路径
SimpleDateFormat sdf = new SimpleDateFormat("yyyy/MM/dd/");
String datePath = sdf.format(new Date());
//uuid作为文件名
String uuid = UUID.randomUUID().toString().replaceAll("-", "");
//后缀和文件后缀一致
int index = fileName.lastIndexOf(".");
// test.jpg -> .jpg
String fileType = fileName.substring(index);
return new StringBuilder().append(datePath).append(uuid).append(fileType).toString();
}
}我一般写代码的顺序为：Controller----service----serviceImpl----mapper，在方法学一般先写调用体，根据调用写对应的实现，下面我们按照这个顺序来写：
controller包：
NotesController.java
package ***.example.memohehang.controller;
import ***.example.memohehang.***mon.R;
import ***.example.memohehang.domain.Notes;
import ***.example.memohehang.service.NotesService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.*;
@Controller
@RequestMapping("/note")
public class NotesController {
@Autowired
private NotesService notesService;
// 添加
@RequestMapping("/save")
@ResponseBody
public R save(@RequestBody Notes notes)
{
System.out.println("添加备忘录：" + notes);
return notesService.addNote(notes);
}
// 根据noteid查询对应的note
@RequestMapping ("/selectByNote/{noteid}")
@ResponseBody
public R selectByNote(@PathVariable("noteid") Integer noteid)
{
return notesService.selectByNote(noteid);
}
// 查询 只显示用户自己的
@RequestMapping ("/selectAllByUserID/{userid}")
@ResponseBody
public R selectAllById(@PathVariable("userid") Integer userid,@RequestParam(defaultValue = "1") Integer currentPage)
{
return notesService.selectAllById(userid,currentPage);
}
// 查询最近即将截止的未完成的备忘录的时间差
@RequestMapping ("/selectTime/{userid}")
@ResponseBody
public R selectcutDownTime(@PathVariable("userid") Integer userid)
{
return notesService.selectcutDownTime(userid);
}
// 分类查询
@RequestMapping ("/selectByType/{userid}/{type}/{isFinish}")
@ResponseBody
public R selectByType(@PathVariable("userid") Integer userid, @PathVariable("type") Integer type,@PathVariable("isFinish") Integer isFinish,@RequestParam(defaultValue = "1") Integer currentPage)
{
return notesService.selectByType(userid,type,isFinish,currentPage);
}
// 修改
@RequestMapping("/update")
@ResponseBody
public R update(@RequestBody Notes notes)
{
return notesService.update(notes);
}
// 删除
@DeleteMapping("/delete/{id}")
@ResponseBody
public R delete(@PathVariable("id") Integer id)
{
return notesService.delete(id);
}
}
TypeController.java
package ***.example.memohehang.controller;
import ***.example.memohehang.***mon.R;
import ***.example.memohehang.service.TypeService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.*;
@Controller
@RequestMapping("/type")
public class TypeController
{
@Autowired
private TypeService typeService;
// 获取编号与类型的映射表
@ResponseBody
@GetMapping("/getMapping")
public R typeMapping()
{
return typeService.typeMapping();
}
}
UploadController.java
package ***.example.memohehang.controller;
import ***.example.memohehang.***mon.R;
import ***.example.memohehang.service.OssUploadService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.multipart.MultipartFile;
@RestController
public class UploadController
{
@Autowired
private OssUploadService ossUploadService;
@PostMapping("/upload")
public R uploadImg(MultipartFile img)
{
return ossUploadService.uploadImg(img);
}
}UserController.java
package ***.example.memohehang.controller;
import ***.example.memohehang.***mon.R;
import ***.example.memohehang.domain.User;
import ***.example.memohehang.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;
@RestController
@RequestMapping("/user")
public class UserController {
@Autowired
private UserService userService;
// 登录功能
@RequestMapping(value = "/login", method = RequestMethod.POST)
public R login(@RequestBody User user)
{
return userService.login(user);
}
// 注册功能
@RequestMapping(value = "/register", method = RequestMethod.POST)
public R register(@RequestBody User user)
{
return userService.register(user);
}
// 根据用户id查询
@RequestMapping ("/selectUserById/{userid}")
@ResponseBody
public R selectUserById(@PathVariable("userid") Integer userid)
{
return userService.selectUserById(userid);
}
}
我们用mybatisplus自带的查询函数即可完成所有的CRUD，因此我们不需要写SQL语句
service包：
NotesService
package ***.example.memohehang.service;
import ***.baomidou.mybatisplus.extension.service.IService;
import ***.example.memohehang.***mon.R;
import ***.example.memohehang.domain.Notes;
import ***.example.memohehang.domain.User;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestParam;
public interface NotesService extends IService<Notes>
{
/**
* 添加备忘录
* @param notes
* @return
*/
public R addNote(Notes notes);
/**
* 根据noteid查询note
* @param noteid
* @return
*/
public R selectByNote(Integer noteid);
/**
* 查询 只显示用户自己的
* @param userid
* @param currentPage
* @return
*/
public R selectAllById(Integer userid,Integer currentPage);
/**
* 查询最近即将截止的未完成的备忘录的时间差
* @param userid
* @return
*/
public R selectcutDownTime(Integer userid);
/**
* 分类查询
* @param userid
* @param type
* @param isFinish
* @param currentPage
* @return
*/
public R selectByType(Integer userid, Integer type,Integer isFinish,Integer currentPage);
/**
* 修改
* @param notes
* @return
*/
public R update(Notes notes);
/**
* 删除
* @param id
* @return
*/
public R delete(Integer id);
}
OssUploadService
package ***.example.memohehang.service;
import ***.example.memohehang.***mon.R;
import org.springframework.web.multipart.MultipartFile;
public interface OssUploadService {
//图片上传到七牛云
R uploadImg(MultipartFile img);
}TypeService
package ***.example.memohehang.service;
import ***.baomidou.mybatisplus.extension.service.IService;
import ***.example.memohehang.***mon.R;
import ***.example.memohehang.domain.Type;
public interface TypeService extends IService<Type>
{
/**
* 获取所有类型
* @return
*/
public R typeMapping();
}
UserService
package ***.example.memohehang.service;
import ***.baomidou.mybatisplus.extension.service.IService;
import ***.example.memohehang.***mon.R;
import ***.example.memohehang.domain.User;
public interface UserService extends IService<User>
{
/**
* 登录
* @param user
* @return
*/
public R login(User user);
/**
* 注册
* @param user
* @return
*/
public R register(User user);
/**
* 根据id查询用户
* @param userid
* @return
*/
public R selectUserById(Integer userid);
}
接下来在service包中创建Impl，注意第一个 “ I ” 是大写的 “ i ”，第二个是小写的 “ L ”
Impl包：
NotesServiceImpl.java
package ***.example.memohehang.service.Impl;
import ***.baomidou.mybatisplus.core.conditions.query.QueryWrapper;
import ***.baomidou.mybatisplus.core.metadata.IPage;
import ***.baomidou.mybatisplus.extension.plugins.pagination.Page;
import ***.baomidou.mybatisplus.extension.service.impl.ServiceImpl;
import ***.example.memohehang.***mon.R;
import ***.example.memohehang.domain.Notes;

至此后端工程全部创建完毕，按照下图检查一下是否有缺少，注意Mapper可写也可以不写，因为我们不需要写SQL语句，不需要调用Mapper，全部完毕后就可以运行项目，利用apipost进行测试，或者前端创建完后直接集成测试
（6）前端工程
我们采用uniapp来写前端代码，按照以下步骤建立项目
输入项目名称，选择vue2
我们需要用到以下uniapp的组件，可以从uniapp组件库下载，链接为：组件使用的入门教程 | uni-app官网
对应的矢量图标可以在阿里巴巴矢量图库下载，链接为iconfont-阿里巴巴矢量图标库
然后我们在根目录下建立store文件夹，在此文件夹下建立index.js，用于存放一些函数
index.js
export function getUserid() {
let userid = uni.getStorageSync("userid");
if (userid == null || userid === '')
return '';
else
return userid;
}
export function getNoteid()
{
let noteid = uni.getStorageSync("noteid");
if (noteid == null || noteid === '')
return '';
else
return noteid;
}
export function getUsername()
{
let username = uni.getStorageSync("username");
if (username == null || username === '')
return '';
else
return username;
}
export function hasLogin() {
let userid = uni.getStorageSync("userid");
if (userid == null || userid === '') {
return false;
} else
return true;
}
export function logout() {
uni.removeStorageSync("userid");
uni.removeStorageSync("noteid");
uni.removeStorageSync("username");
uni.redirectTo({
url: "/pages/mine"
});
}随后修改pages.json中修改相关页面配置文件，可以先创建相关页面后再进行此步骤，以免编译时报错
pages.json
{
"pages": [ //pages数组中第一项表示应用启动页，参考：https://uniapp.dcloud.io/collocation/pages
{
"path": "pages/Main",
"style": {
"navigationBarTitleText": "个人备忘录"
}
}
,{
"path" : "pages/Login",
"style" :
{
"navigationBarTitleText": "登录",
"enablePullDownRefresh": false
}
}
,{
"path" : "pages/Main",
"style" :
{
"navigationBarTitleText": "所有备忘录",
"enablePullDownRefresh": false

},
{
"path" : "pages/mine",
"style" :

"style" :
{

"enablePullDownRefresh": false
}
}
,{
"path" : "pages/catNote",
"style" :
{
"navigationBarTitleText": "查询备忘录",
"enablePullDownRefresh": false
}
}
,{
"path" : "pages/Register",
"style" :
{
"navigationBarTitleText": "注册",
"enablePullDownRefresh": false
}
}
],
"globalStyle": {
"navigationBarTextStyle": "black",
"navigationBarTitleText": "个人备忘录",
"navigationBarBackgroundColor": "#F8F8F8",
"backgroundColor": "#F8F8F8"
},
"tabBar": {
"list": [
{
"text": "首页",
"pagePath": "pages/Main",
"iconPath": "static/images/首页.png",
"selectedIconPath": "static/images/首页2.png"
},
{
"text": "记录",
"pagePath": "pages/addNote",
"iconPath": "static/images/记录.png",
"selectedIconPath": "static/images/记录1.png"
},
{
"text": "分类",
"pagePath": "pages/catNote",
"iconPath": "static/images/分类.png",
"selectedIconPath": "static/images/分类2.png"
},
{
"text": "我的",
"pagePath": "pages/mine",
"iconPath": "static/images/我的.png",
"selectedIconPath": "static/images/我的2.png"
}
]
},
"uniIdRouter": {}
}
然后再pages中建立以下页面文件，我这里没有创建同名目录
