将 org.apache.felix.scr.annotations 更改为 org.osgi.service.component.annotations 后如何获取服务引用

命令错误

我添加了一些编译依赖项 例如在 features.xml 中

<bundle>mvn:org.osgi/org.osgi.resource/1.0.0</bundle>
<bundle>mvn:org.osgi/org.osgi.service.component/1.4.0</bundle>
<bundle>mvn:org.osgi/org.osgi.service.component.annotations/1.4.0</bundle>
<bundle>mvn:org.osgi/org.osgi.service.metatype.annotations/1.4.0</bundle>

但它无法解决问题 这就是我得到的，我无法修复它 控制台无法获取捆绑包、服务或组件等。 任何人都可以给我一些建议， 预先感谢您！

原因是 io.github.classgraph 加载类 io.atomix.utils.NamedType io.atomix.cluster.protocol.HeartbeatMembershipProtocol$Type 而 org.apache.felix.framework 加载类 io.atomix.utils.NamedType，但 HeartbeatMembershipProtocol $Type 应该类型转换为 NamedType。

解决的方法是在pom.xml中添加一些DynamicImport-Package属性

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.felix</groupId>
            <artifactId>maven-bundle-plugin</artifactId>
            <version>4.1.0</version>
            <extensions>true</extensions>
            <configuration>
                <instructions>
                    <DynamicImport-Package>io.atomix.cluster.*,io.atomix.primitive.*,io.atomix.core.*,io.atomix.protocols.*</DynamicImport-Package>
                </instructions>
            </configuration>
        </plugin>
    </plugins>
</build> 

因此，当加载您的包时，依赖项 jar 也将被加载。

感谢那些给我线索的人！
