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。

功能模块图

(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


    4.0.0
    
        org.springframework.boot
        spring-boot-starter-parent
        2.7.8

                            lombok
                        
                    
                
            
            
                org.apache.maven.plugins
                maven-compiler-plugin
                
                    9
                    9
                
            
        
    

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: com.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:
  accessKey: yourAK
  secretKey: yourSK
  bucket: yourbucket

接下来在项目下创建如下几个包:

common包: 
R.java

在common文件下创建 R.java 类,主要用于封装返回给前端的数据:

package com.example.memohehang.common;
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 success(Object data)
    {
        return success(200, "操作成功", data);
    }
    public static R success(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 com.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 com.example.memohehang.domain;
import com.baomidou.mybatisplus.annotation.IdType;
import com.baomidou.mybatisplus.annotation.TableId;
import com.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 com.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 com.example.memohehang.domain;
import lombok.AllArgsConstructor;
import com.baomidou.mybatisplus.annotation.IdType;
import com.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 com.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 com.example.memohehang.controller;
import com.example.memohehang.common.R;
import com.example.memohehang.domain.Notes;
import com.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 com.example.memohehang.controller;
import com.example.memohehang.common.R;
import com.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 com.example.memohehang.controller;
import com.example.memohehang.common.R;
import com.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 com.example.memohehang.controller;
import com.example.memohehang.common.R;
import com.example.memohehang.domain.User;
import com.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

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
            }

                "navigationBarTitleText": "所有备忘录",
                "enablePullDownRefresh": false
            }
            
        },
				{
				    "path" : "pages/mine",
				    "style" :                                     
				    {
				        "navigationBarTitleText": "个人中心",
				        "enablePullDownRefresh": false
				    }
				    
				}
        ,{
            "path" : "pages/addNote",
