Spring Boot應用程序未能以類路徑啓動：[]

Question

我生成了一個帶有jHipster的Spring Boot應用程序，添加了我以前的項目（非jhipster項目）中的一些代碼，並嘗試使用IDEA運行它。首先，我收到類似於this的錯誤消息，稱「命令行太長..」（我正在運行Windows 10 x64）。我點擊啓用，但然後我得到了一個這樣的錯誤。：

"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

07:48:57.570 [restartedMain] DEBUG org.springframework.boot.logging.ClasspathLoggingApplicationListener - Application failed to start with classpath: [] 

後，我試了一下。 /mvnw：

我貼我的pom.xmlhere。

我創建了一個全新的項目，並開始添加我一個接一個的Maven依賴項，然後在每一步之後都運行項目。類路徑的問題發生時，當我添加兩個春季批次和番石榴。

<dependency> 
    <groupId>org.springframework.boot</groupId> 
    <artifactId>spring-boot-starter-batch</artifactId> 
</dependency> 
<!-- https://mvnrepository.com/artifact/com.google.guava/guava --> 
<dependency> 
    <groupId>com.google.guava</groupId> 
    <artifactId>guava</artifactId> 
    <version>${guava-core.version}</version> 
</dependency> 

Answer 1

我在相同的錯誤消息的jHipster應用程序有這個同樣的問題，對我來說是根本原因對我來說是在應用dev.yml春天郵件設置誤格式化（縮進）。我只是複製/粘貼來自另一個項目的設置，並且IntelliJ縮進它們與原始代碼中的有點不同，並且因爲它們無法解析。

每次啓動應用程序時，都會出現這些「顯示屬性」的東西，但至少對我而言，它們並不涉及真正的問題。希望這有助於找到事業的根源！乾杯，
