java - Intellij Idea Spring引导开发工具在创建bean时带有liveloader扩展错误
问题描述
我试图让我的 Java 应用程序在进行更改后自动更新。当我更改 html 或 css 文件时，自动更新内容工作正常，但是当我更改 java 类时，我的项目会自动重建，但会引发错误。当我通过单击停止并在 ide 中重新运行我的应用程序时，一切正常。
我正在使用 intellij Idea ide，我在这里更改了 2 设置
在注册表中的菜单 shift+cltr+a 我启用了运行时允许编译
在构建设置中，我启用了自动构建
我将非常感谢您的每一次帮助。
我得到的错误

在旧版本的 spring-boot 2.0.3 中，html 自动更新正在工作，但是当我更改 java 类时，一切都在构建 amd 编译正常，但是我在 chrome 中的网页没有加载它给出了错误
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.
Mon Jul 09 15:29:48 CEST 2018
There was an unexpected error (type=Not Found, status=404).
No message available
当我在 SpringBootApplication 类中更改某些内容并保存更改时，它会自动构建并且一切正常，我的 html 页面以 chrome 显示，但是当我更改其他 java 类时，它会给出上面显示的错误。
