Osk*_*iak 2 java spring intellij-idea maven spring-boot
我骑着那些有关spring开发工具和热重装的文档
https://docs.spring.io/spring-boot/docs/current/reference/html/howto-hotswapping.html https://docs.spring.io/spring-boot/docs/current/reference/html/using -boot-devtools.html#using-boot-devtools-restart-exclude
并且据此可以热重载Java和支持的React / Typescript / webpack应用
这是我们的架构(快捷方式)
mainmodule
backendModules <- those modules are just maven project have theirs poms and etc
backendModule1
backendModule2
fontendModule
content <- React/Typescript/Webpack/Less etc

backendModule2-我们用来启动后端backendModule1-只是一些附加服务fontendModule / content-是我们的整个React应用
如果我说要重新加载前端文件,我是对的,我必须:
配置Intellij,因为我通常在后端执行<-这很容易
1a。更改注册表
1b。自动选择构建项目
我的问题是我必须执行哪些操作才能强制重新加载前端文件-因此,开发人员只需运行1个应用,然后将自动重新加载后端+前端
将前端扩展添加到资源模式(Intellij:构建,执行->编译器)?jsx,json,js,less等?
根据文档添加“ spring.devtools.restart.additional-paths”
有人能做到吗?我们没有收到任何错误等信息。
让我知道是否有不清楚的地方,以便我们澄清一下

我知道有两种方法可以做到这一点。
1)使用Intellij File Watcher插件
2)运行webpack开发服务器作为您的spring-boot应用程序的反向代理
1)
现在,如果将文件保存在定义的范围内,则将运行webpack任务。之后,您必须在浏览器中刷新页面。从https://intellij-support.jetbrains.com得到了这个想法
2)这种方法更高级,但更难正确配置。您将具有自动重新加载(页面刷新)和完全热加载(反应状态持续)的功能
基本思想是运行一个webpack-dev-server并将该服务器用作spring-boot后端的反向代理。开发服务器将自己处理对热重载内容的请求,并将其他所有内容传递给您的后端。从https://www.codingbismuth.com/获得了这个想法。

spring boot应用程序在:8087上运行,而webpack开发服务器在:8888上运行。现在在您的index.html中包含mainbundle.js。运行您的spring-boot应用程序,然后在第二个终端中运行:
npm run start:dev
