JBoss保险丝+JPA/Hibernate
JBoss Fuse +JPA/Hibernate
我在 JBoss Fuse 6.2 中有 OSGI 包，它导入带有实体和 dao classes 的 jar。
罐子包含：

Karaf 似乎在 persistence.xml 中找到了 class 定义，但无法加载实体 class。
欢迎提出任何建议。
看来 spring 是 osgi 的错误选择，并在那里得到证实 Using both Blueprint and Spring (Not spring-dm) with OSGi。
所以用Apache Aries是很有必要的。你可以在那里找到工作示例 jpa+fuse
https://github.com/pires/fabric8-persistence-hibernate
https://github.com/FuseByExample.
由于实体是从另一个 jar 导入并通过 EntityManager 由 bundle 加载的，您可能需要将 jar 构建为 bundle 并导出包，然后使用 `maven-bundle-plugin 导入包' 例如
罐子：
<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-bundle-plugin</artifactId>
<extensions>true</extensions>
<configuration>
<instructions>
<Bundle-SymbolicName>${project.artifactId}</Bundle-SymbolicName>
<Import-Package />
<DynamicImport-Package>*</DynamicImport-Package>
<Export-Package>com.company.model.*</Export-Package>
</instructions>
</configuration>
</plugin>
OSGi 捆绑包：
<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-bundle-plugin</artifactId>
<extensions>true</extensions>
<configuration>
<instructions>
<Bundle-SymbolicName>${project.artifactId}</Bundle-SymbolicName>
<Import-Package>com.company.model.entity</Import-Package>
<DynamicImport-Package>*</DynamicImport-Package>
<Export-Package />
</instructions>
</configuration>
</plugin>
您可以使用 packages:imports、packages:exports 检查包导入、导出。最好创建一个功能来定义它所依赖的包。
