Spring Boot不是作为一个独立的jar启动的

Question

我正在使用带有Runnable Jar的Export命令使用Spring Boot创建一个独立的jar，并尝试在命令提示符下运行jar但是它抛出了以下错误，同样的应用程序在eclipse中运行。我不能使用maven，我也没有在我的应用程序中使用spring-boot-thymeleaf。即使添加了spring-boot-autoconfigurator-thymeleaf jar，我也会收到此错误。

请建议知道我为什么会收到此错误，我需要启动spring-boot应用程序jar作为export-＆gt; Runnable jar（因为我不能使用maven来生成jar），我不应该得到上述异常。

Answer 1

我冒险得到一些downvotes，但我认为没有maven你不能包含Spring启动应用程序运行所需的一切，因为在maven pom.xml中你不仅包括依赖项，还包括很少的插件，如tomcat插件。因此，下一步是开始使用构建管理工具，因为您正在使用弹簧和弹簧引导，这在我的意见中几乎是强制性的。 Maven难以掌握，但易于启动和使用，所以最好看看这个官方的简单教程：https://maven.apache.org/guides/getting-started/maven-in-five-minutes.html
