mvn package在我試圖在Spring Boot應用程序中增強JPA實體時在openjpa-maven-plugin:enhance階段失敗。無法使用Spring Boot運行OpenJPA實體的靜態增強
還有很長的錯誤描述
enhance failed: MetaDataFactory could not be configured (conf.newMetaDataFactoryInstance() returned null).
no configuration properties were found.
它列出了一些原因：
-
確保您有一個META-INF/persistence.xml文件，它是 可用在您的類路徑
- 我使用
spring-data-jpa與Java的配置，而且也沒有
persistence.xml。 可以做openjpa:enhance沒有
嗎？
- 我使用
-
確保屬性文件你正在使用的配置 可用。如果您正在使用Ant，請參閱任務嵌套元素的或 屬性。
- 我指定Spring的
org.springframework.boot.autoconfigure.orm.jpa.JpaBaseConfiguration的子類的所有屬性的OpenJPA - 見下面的類。 這可能是我需要改變的，但是如何？並在哪裏指定屬性文件，以便openjpa-maven-plugin可以找到它？如果你的安全策略是過於嚴格的
- 我指定Spring的
-
這也可能發生，如果你的OpenJPA的分配罐已損壞，或 。
- 排除了 - 我查了重新下載OpenJPA的罐子
checksumPolicy=fail所以這是證明他們沒有損壞，再加上我沒有使用任何安全策略在這個水平。
- 排除了 - 我查了重新下載OpenJPA的罐子
的pom.xml
