【问题标题】：Compilation error while running a spring boot application运行 Spring Boot 应用程序时出现编译错误
【发布时间】：2017-10-21 11:21:39
【问题描述】：

我有一个没有在 intellj 中运行的 Spring boot 应用程序，即使这个应用程序在 eclipse 中运行，我也总是必须将构建路径中的“Jre 库”移动到顶部，然后运行 mvn install。

当我运行 mvn clean 然后 man install 时会发生此错误。

【问题讨论】：

“不在 intellij 中运行”究竟是什么意思？它编译吗？如果不是，编译错误是什么？如果它编译但运行SpringDemoAppApplication 时出现故障，那么您能描述什么该故障是什么吗？你有堆栈跟踪吗？此应用程序是否从命令行构建和运行？
@glitch : 问题中添加了错误。

标签： eclipse maven spring-boot

【解决方案1】：

您的 pom.xml 中的 spring-boot-starter-web 依赖项具有 scope=test 但您有使用该工件提供的类的非测试代码，因此只需从该依赖项中删除范围元素，然后“web”类将是在您的“主要”源代码树中可用。
