Spring Boot-exception, Fehler bei der Erstellung bean

Ich habe ein maven, spring-boot-Anwendung; es ist wunderbar zu arbeiten, wenn ich es direkt aus Eclipse, aber wenn ich es aufrufen-Befehlszeile:

1) mvn package

2) java –jar target/myapp.jar

wirft Fehler:

hier meine pom.xml obwohl, wenn ich starten Sie die Anwendung aus eclipse ist in Ordnung, also denke ich nicht, dass der Fehler hier:

Anwendung.Eigenschaften:

jdbc.driverClassName = com.mysql.jdbc.Driver
jdbc.url = jdbc:mysql://localhost:3306/myapp
jdbc.username = myuser
jdbc.password = mypass
hibernate.dialect = org.hibernate.dialect.MySQLDialect
hibernate.show_sql = true
hibernate.format_sql = true

Irgendwelche Ideen?

    Die Konfiguration ändern, ich denke, es wird funktionieren :

    # Connection url for the database "myapp"
    spring.datasource.url = jdbc:mysql://localhost:3306/myapp
    # Username and password
    spring.datasource.username = myuser
    spring.datasource.password = mypass
    # Show or not log for each sql query
    spring.jpa.show-sql = true
    spring.jpa.hibernate.ddl-auto = update
    # Naming strategy
    spring.jpa.hibernate.naming-strategy = org.hibernate.cfg.ImprovedNamingStrategy
    # Allows Hibernate to generate SQL optimized for a particular DBMS
    spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect

    Überprüfen Sie, dass in Ihrem pom.xml Sie haben diese Abhängigkeiten :

           <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-data-jpa</artifactId>
            </dependency>
    
            <dependency>
                <groupId>mysql</groupId>
                <artifactId>mysql-connector-java</artifactId>
                <scope>runtime</scope>
            </dependency>
    • Hey, danke für die Antwort, auf den Beitrag habe ich auf die Anwendung hinzuzufügen.Eigenschaften, macht es richtig aussieht?
    • Ich update meine Antwort hoffen, dass diese Arbeit für Sie !

    Wenn Sie das Protokoll Lesen, wieder, finden Sie
    java.lang.IllegalStateException: required key [datasource.sampleapp.hibernate.dialect] not found, die Sie benötigen, definieren Sie diese Eigenschaft zum erstellen der bean.
