我骑了关于spring dev工具和热重载的文档
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
根据那是看到热备份java和支持的React / Typescript / webpack应用程序有这样的可能性
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 - 只是一些额外的服务 fontendModule / content - 是我们的全部反应应用
如果我说要为我们的前端文件重新加载,我是否正确:
配置Intellij,因为我正常为后端&lt; - 这很容易
1a上。更改注册表
1b中。自动选择构建项目
我的问题是我必须做什么来强制重新加载前端文件 - 所以开发人员只需运行1个应用程序然后后端+前端将自动重新加载
向资源模式添加前端扩展(Intellij:构建,执行 - &gt;编译器)? jsx,json,js,less等等?
根据doc添加“spring.devtools.restart.additional-paths”
有没有人能够做到这一点?我们没有得到任何错误等...
如果有些事情似乎不清楚,请告诉我,以便我们澄清一下
答案 0 :(得分:2)
我知道有两种不同的方法可以做到这一点。
1)使用Intellij文件观察器插件
2)运行webpack dev服务器作为spring-boot应用程序的反向代理
1)
现在,如果您在定义的范围内保存文件,则会运行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) 这种方式更先进,但更难配置正确。您将自动重新加载(页面刷新)和完全热重新加载(反应状态仍然存在)
基本思想是运行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热重新加载内容的请求,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。
作为示例配置

Spring boot应用程序运行于:8087,webpack dev服务器运行于:8888。现在在index.html中包含mainbundle.js。 运行spring-boot应用程序并在第二个终端运行中运行:
npm run start:dev
访问:8888上的网页,以便在文件更改时进行热重新加载。
