我有一個使用gradle的spring引導應用程序。我配置了gradle以將構建參數注入到application.properties中。如果在spring啓動時沒有提供屬性文件，如何跳過佔位符值？
這是我的gradle片段。
processResources {
expand project.properties
}
在application.properties，我有以下值
service.name=${name}
service.version=${version}
名稱和版本都將被注入的gradle這個特性。
當我運行./gradlew bootRun或./gradlew構建時，我看到application.properties文件被替換爲正確的值。
但是，當我從Intellij啓動使用springBoot Runner時，出現以下錯誤。
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.doCreateBean(AbstractAutowireCapableBeanFactory.java:543) ~[spring-beans-4.2.7.RELEASE.jar:4.2.7.RELEASE]
當我更換application.properties如下，它工作在春季啓動跑者的IntelliJ但gradle這個構建失敗
service.name=${name: not configured}
service.version=${version : not configured}
我怎麼能告訴春天開機忽略任何缺少的佔位符值？
的gradle這個例外有堆棧跟蹤
的例外是：

你可以發佈代碼與值注入？ – Ozilophile
你是什麼意思？春天做注射。 –
您的示例不完整。正如@Ozilophile建議的那樣，查看代碼將屬性注入到com.company.foo.web中會很有幫助。控制器類 –
