spring boot 设置应用名称 spring boot桌面应用

🎈概述

在习惯使用springboot开发代码之后，在我们自己进行桌面程序编码的时候，发现很多的不方便，比如连接数据库，读取配置文件，循环依赖，日志记录，定时任务等等。这篇文章详细介绍了使用springboot搭建一个桌面程序easytodo，一个桌面便签和任务，使用jpa+h2作为本地存储，打包成windows应用。

•  支持统计
•  桌面展示
•  静态展示，单一颜色，防止审美疲劳

🦜UI设计

使用figma工具设计的，具体页面地址 easytodo页面设计，设计要求是颜色冷淡为主，主要颜色是淡蓝色和白色，用橙色作为点缀😏。设计了三个logo，个人比较喜欢第一个，可惜已经别人用了，最后采用的第三个，我没有去抄袭别人的图标，确实就是按照功能直接设计出来的，圆形打个勾勒表示任务完成。

🐎主要代码

废话不多说直接上代码😎

具体效果

调整页面非常的废时间，特别是布局组件的位置，因为我采用的是动态生成大小很多，组件的位置会和当前使用的屏幕的分辨率有关系。

🖼️使用环境

• windows11
• jdk1.8

🥷知识点

• springboot启动非web项目
• swing基础知识
• h2数据库和sqlite选择
• java打包成windows应用

spingboot启动swing

因为JFrame的构造方法会抛出一个HeadlessException 异常，修改springbootapplicationbuilder中的headless=false，web=none，然后后面直接执行自己的组件。然后通过ApplicationContext获取定义的对象就可以。如果是一般的程序，直接SpringbootApplication.run就行不需要设置参数。

//这里是源码里面的JFrame构造方法，会抛出异常直接springbootApplication.run会报错
public JFrame() throws HeadlessException {
        super();
        frameInit();
    }

package com.mucong;

import com.mucong.easytodo.EasytodoApp;
import org.springframework.beans.BeansException;
import org.springframework.boot.WebApplicationType;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.context.ApplicationContext;

@SpringBootApplication
public class App  {

    public static void main(String[] args) {
        try {
            SpringApplicationBuilder builder = new SpringApplicationBuilder(App.class);
            //设置headless=false，设置web为none
            ApplicationContext context = builder.headless(false).web(WebApplicationType.NONE).run(args);
            //获取对象然后正常执行
            EasytodoApp easytodoApp = context.getBean(EasytodoApp.class);
            easytodoApp.createUI();
        } catch (BeansException e) {
            e.printStackTrace();
        }
    }
}

总结

目前已经搭建了整体的框架，和基本的页面组件编写，接下来需要编写后续的功能实现，任务的添加和状态修改，便签的展示，桌面锁定（就是那个图钉的功能）
