Spring Boot应用程序未能以类路径启动：[]

Question

我生成了一个带有jHipster的Spring Boot应用程序，添加了我以前的项目（非jhipster项目）中的一些代码，并尝试使用IDEA运行它。首先，我收到类似于this的错误消息，称“命令行太长..”（我正在运行Windows 10 x64）。我点击启用，但然后我得到了一个这样的错误。：

"C:\Program Files\Java\jdk1.8.0_144\bin\java" -agentlib:jdwp=transport=dt_socket,address=127.0.0.1:51351,suspend=y,server=n -XX:TieredStopAtLevel=1 -noverify -Dspring.output.ansi.enabled=always -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=51350 -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -Dspring.liveBeansView.mbeanDomain -Dspring.application.admin.enabled=true -Dfile.encoding=UTF-8 -classpath C:\Users\User\AppData\Local\Temp\classpath.jar com.test.pc.TestPartsComposerApp

后，我试了一下。 /mvnw：

我贴我的pom.xmlhere。

我创建了一个全新的项目，并开始添加我一个接一个的Maven依赖项，然后在每一步之后都运行项目。类路径的问题发生时，当我添加两个春季批次和番石榴。

<dependency> 
    <groupId>org.springframework.boot</groupId> 
    <artifactId>spring-boot-starter-batch</artifactId>

</dependency> 

Answer 1

我在相同的错误消息的jHipster应用程序有这个同样的问题，对我来说是根本原因对我来说是在应用dev.yml春天邮件设置误格式化（缩进）。我只是复制/粘贴来自另一个项目的设置，并且IntelliJ缩进它们与原始代码中的有点不同，并且因为它们无法解析。

每次启动应用程序时，都会出现这些“显示属性”的东西，但至少对我而言，它们并不涉及真正的问题。希望这有助于找到事业的根源！干杯，
