Wie überspringe ich den Platzhalterwert, wenn er nicht in der Eigenschaftendatei im Spring Boot enthalten ist?

Ich habe eine Spring-Boot-Anwendung, die Gradle verwendet. Ich habe Gradle konfiguriert, um Build-Parameter in application.properties zu injizieren.Wie überspringe ich den Platzhalterwert, wenn er nicht in der Eigenschaftendatei im Spring Boot enthalten ist?

Hier ist mein Graple Snippet.

processResources { 
    expand project.properties 
}

Im application.properties, ich habe folgende Werte

service.name=${name} 
service.version=${version}

Namen und die Version sind Eigenschaften von gradle, die injiziert werden.

Wenn ich ./gradlew BootRun oder ./gradlew Build ausführen, sehe ich die Datei application.properties mit korrekten Werten ersetzt.

Aber wenn ich die Verwendung von SpringBoot Runner von Intellij starte, erhalte ich den folgenden Fehler.

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'Controller': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private java.lang.String com.company.foo.web.Controller.version; nested exception is java.lang.IllegalArgumentException: Could not resolve placeholder 'version' in string value "${version}" 
    at org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor.postProcessPropertyValues(AutowiredAnnotationBeanPostProcessor.java:334) ~[spring-beans-4.2.7.RELEASE.jar:4.2.7.RELEASE] 
    at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.populateBean(AbstractAutowireCapableBeanFactory.java:1214) ~[spring-beans-4.2.7.RELEASE.jar:4.2.7.RELEASE] 
    at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean(AbstractAutowireCapableBeanFactory.java:543) ~[spring-beans-4.2.7.RELEASE.jar:4.2.7.RELEASE]

, wenn ich die application.properties wie folgt ersetzen, funktioniert es im Frühjahr Boot-Läufer in intellij aber die gradle Build fehlschlägt

service.name=${name: not configured} 
    service.version=${version : not configured}

wie kann ich Frühling Boot sagen alle fehlenden Platzhalter Werte zu ignorieren?

Die gradle Ausnahme mit stacktrace

Ausnahme ist:

Können Sie den Code mit dem Wert injection? – Ozilophile

was meinst du? Frühling macht die Injektion. –

Ihr Beispiel ist unvollständig. Wie von @Ozilophile vorgeschlagen, wäre es hilfreich, den Code zu sehen, in den Sie Eigenschaften in Ihre com.company.foo.web einfügen.Controller-Klasse –

ich das gleiche Problem haben - wirklich ärgerlich. Die beste Lösung, die ich bisher gefunden habe, ist, eine Run/Debug-Konfiguration in IntelliJ zu speichern und dann die Konfiguration zu bearbeiten, indem ich festlege, dass die Gradle-Task processResources vor dem Start ausgeführt werden soll.

Ich löse das mit Federprofilen. https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-profiles.html

In application.properties Ich habe

service.version=dev

In application-production.properties Ich habe

service.version=${version}

Und schließlich diese in der build.gradle Datei

processResources { 
    filesMatching('application-production.properties') { 
     expand(project.properties) 
    } 
}

In den Entwicklungs-, Test- und Integrationstests wird die Version sei "dev", wird beim Ausführen mit dem Produktionsprofil die Build-Version verwendet.

Dies funktioniert auch, wenn die Anwendung direkt von IntelliJ ausgeführt wird.

Wie überspringe ich den Platzhalterwert, wenn er nicht in der Eigenschaftendatei im Spring Boot enthalten ist?
