java - EclipseLink:如何为 eclipselink 2.7.0 设置 SLF4J 记录器

Question

Bundle org.eclipse.persistence.extension_2.7.0.qualifier.jar(我安装到 osgi 框架)包含类 org.eclipse.persistence.logging.slf4j.SLF4JLogger。在我的持久性文件中我有

<property name="eclipselink.logging.logger" value="org.eclipse.persistence.logging.slf4j.SLF4JLogger"/>

但是我明白了

Exception Description: ClassNotFound: [org.eclipse.persistence.logging.slf4j.SLF4JLogger] specified in [eclipselink.logging.logger] property.
Internal Exception: java.lang.ClassNotFoundException: org.eclipse.persistence.logging.slf4j.SLF4JLogger not found by org.eclipse.persistence.jpa [11]

我检查过包 org.eclipse.persistence.extension_2.7.0.qualifier.jar 不导出包 org.eclipse.persistence.logging.slf4j 所以，谁能解释一下如何使eclipselink登录slf4j？

Answer 1

确保包含“org.eclipse.persistence.extension”jar，它应该可以正常工作。我使用的 Maven 坐标是

  <dependency>
     <groupId>org.eclipse.persistence</groupId>
     <artifactId>org.eclipse.persistence.extension</artifactId>
     <version>2.7.2</version>
     <scope>runtime</scope>
  </dependency>
