Spring-Boot-Anwendung Start fehlgeschlagen

Question

Ich habe grundlegende Spring-Boot-Anwendung mit Tomcat-Container erstellt. Nachdem ich das Glas mit Maven gebaut habe, führe ich es als java -jar mybootapp-1.0.0.jar. Dann ist folgender Fehler aufgetreten. Irgendwie benutze ich mvn spring-boot:run Befehl, um die App zu starten, läuft es gut. Aber was ist der Grund dafür, Fehler beim normalen JAR-Dateilauf zu geben.

Answer 1

1.4.3.RELEASE derzeit von den Spiegeln erscheint

zu fehlen

https://repo.maven.apache.org/maven2/org/springframework/boot/spring-boot-starter-parent/

geht nur bis 1.4.2

Answer 2

Da der Tomcatbediener ist Standard-Container für das Frühjahr Boot-Anwendung, die Sie nicht explizit die Abhängigkeiten tomcat angeben. Ich würde Ihnen empfehlen und empfehlen Ihnen dringend, Spring Initializer zu verwenden, um mit der Spring-Boot-Anwendung zu starten.

Darf ich wissen, warum sich Ihre Anwendungsklasse von SpringBootServletInitializer erstreckt? Planen Sie eine schnelle Bereitstellung?

Answer 3

Sie müssen die folgenden Änderungen in der Datei pom.xml vornehmen, wenn Sie den Krieg in Tomcat bereitstellen möchten.

 1) In pom.xml file , make scope as provided for embedded server 

     <dependency> 
      <groupId>org.springframework.boot</groupId> 
      <artifactId>spring-boot-starter-undertow</artifactId> 
       <scope>provided</scope> 
     </dependency> 

     or 

    <dependency> 
     <groupId>org.springframework.boot</groupId> 
     <artifactId>spring-boot-starter-tomcat</artifactId> 
     <scope>provided</scope> 
    </dependency> 

    2) In pom.xml file, make packaging as war 

     <packaging>war</packaging>
