【问题描述】:
我正在开发一个 Web 应用程序,我的后端是 spring boot,前端是 angular 5,它在 4200 端口上运行。我在 Angular 5 登录、家庭应用程序、搜索中有四个组件。当我开始 Spring Boot 项目和 Angular 项目时,我可以通过提供 http://localhost:4200 来导航登录页面。所以它正在导航到http://localhost:4200/login。
这是我的代码:
proxy.conf.json
{
"/": {
"target": "http://localhost:8081",
"secure": false
}
}
package.json:

【问题讨论】:
-
当您收到“whitelabel error page”时,能否提供应用程序的堆栈跟踪信息?
-
服务器端返回此错误。
-
你在spring-boot项目中部署
dist文件夹了吗?你尝试通过postman登录吗? -
是的,我在 src/main/resources/static 文件夹中部署了 dist 文件夹文件。来自邮递员它正在使用 8080 端口@hrdkisback
-
如果您已修复此错误,请提供解决方案。
