本文主要是介绍从0到1为小仙女做一个记录积分的springboot小项目，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
从0到1为女朋友做一个记录积分的springboot小项目
前言
因为疫情的原因没有办法开学,于是我为女朋友设立了一个奖励她的机制,督促她好好学习,好好生活
后来我琢磨这这积分,每天靠人记住也不是一个办法呀,于是就想着做一个springboot的小项目,部署到云端,帮助记一下,顺便复习一下springboot的知识
项目技术
由于项目比较简单,所以用到的技术比较简单
数据库:mysql
后端框架:spring-boot,mybatis,spring-mvc
前端渲染引擎:thymeleaf
前端网页制作:Adobe Photoshop 2021,vscode
前端部分
当然是先让我的小仙女挑选一个喜欢的模板了
这是我们的模板
捣鼓了半天弄成这个样子
后端部分
首先把之前说过的包引入一下
pom文件
<dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><!-- <version>5.1.49</version>--></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-thymeleaf</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-jdbc</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-devtools</artifactId><scope>runtime</scope><optional>true</optional></dependency><dependency><groupId>org.mybatis.spring.boot</groupId><artifactId>mybatis-spring-boot-starter</artifactId><version>2.1.4</version></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><optional>true</optional></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency>
</dependencies><build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId><configuration><excludes><exclude><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId></exclude></excludes></configuration></plugin></plugins>
</build>
导入依赖
server:port: 8081spring:datasource:url: jdbc:mysql://:3306/javaeeusername: rootpassword: 123456driver-class-name: com.mysql.jdbc.Driver
把我们的静态文件导入进来
在HTML中导入我们的thymeleaf
<html lang="en" xmlns:th="http://www.thymeleaf.org">
之后先写我们的Controller类
package com.example.adddata.Controller;import com.example.adddata.Service.DataService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;@Controller
public class DataController {@AutowiredDataService dataService;@GetMapping("/")public String data(Model model) {String data = dataService.getData();System.out.println(data);model.addAttribute("data", data);return "index";}@GetMapping("/add")public String addData(Model model) {dataService.addData("10");return "forward:/";}@GetMapping("/reduce")public String reduceData(Model model) {dataService.reduceData("10");return "forward:/";}
}
Service类
@Service
public class DataServiceImpl implements DataService {@AutowiredDataMapper dataMapper;@Overridepublic String getData() {Data data = dataMapper.getData();String data1 = data.getData();return data1;}@Overridepublic void addData(String data) {Integer A = Integer.parseInt(data);Data data1 = dataMapper.getData();String data2 = data1.getData();Integer B = Integer.parseInt(data2);dataMapper.addData(String.valueOf((B+A)));}@Overridepublic void reduceData(String data) {Integer A = Integer.parseInt(data);Data data1 = dataMapper.getData();String data2 = data1.getData();Integer B = Integer.parseInt(data2);dataMapper.reduceData(String.valueOf((B-A)));}
}
Mapper类
@Mapper
@Repository
public interface DataMapper {@Select("select * from data where id = 1")Data getData();@Update("UPDATE data set data = #{data} where id = 1")void addData(String data);@Update("UPDATE data set data = #{data} where id = 1")void reduceData(String data);
}
Bean类
public class Data {@Overridepublic String toString() {return "Data{" +"id=" + id +", data='" + data + '\'' +'}';}public Integer getId() {return id;}public void setId(Integer id) {this.id = id;}public String getData() {return data;}public void setData(String data) {this.data = data;}Integer id;String data;
}
数据库
云端部署
因为mysql本身已经部署到云端是所以只需要把springboot打成jar包然后部署就可以了
先clean然后package
之后把jar包移入到云服务器上
后台运行上我们的jar包就ok
nohup java -jar (jar包名) &
这是我们的项目地址:
后言
2022.7.15
由于之前那个前端网页做的实在是太丑了
于是我决定重写一下,最近接触到了一个可以把psd转换为vue或者是HTML的在线编辑平台
任性布局 (shagua.wiki)
直接根据教程在ps中安装相对应的插件

这里贴一段我生成的代码
然后暂停掉服务器上的代码
netstat -nlp|grep 8089
//8089是系统启动访问的端口，从输出数据中可以看到线程对应的pid
kill -9 pid
//强制停掉 pid 对应线程
最后看一下效果
