我正在尝试在通配符10上部署生菜6.0.2 (它是为部署OSGI包而定制的)，它连接AWS elasticache。连接URL如下所示：

RedisURI redisURI = RedisURI.Builder.redis(configProperties.getProperty("ECclusterhost"), Integer.parseInt(configProperties.getProperty("ECclusterport"))).withPassword(pswdcharArray).withSsl(true).build();

独立程序执行良好，但是当我尝试在通配符上部署时，它在调用时给出了以下错误：RedisClusterClient.create(redisURI);

由: org.apache.felix.log.LogException: java.lang.NoClassDefFoundError: javax/net/ssl/ssl参数引起. 42多个原因是: Service中的java.lang.ClassNotFoundException: javax.net.ssl.SSLParameters

pom.xml有以下依赖关系：

由于javax.net.ssl是JDK 8的一部分，所以在部署通配符-10时它是不可用的。为了加快响应时间，我在生菜群上提出了同样的问题。

更新：

经过几次调整后，原来的错误就消失了。但是OSGI仍然无法部署反应堆API，现在我收到了以下错误：

ERROR [com.icare.elasticacheclient] (Thread-91) [MSC service thread 1-7] Invocation of 'init' failed.: java.lang.NoClassDefFoundError: Failed to link reactor/core/publisher/DirectProcessor (Module "deployment.elasticacheclient-1.0.0.jar:main" from Service Module Loader): Failed to link reactor/core/publisher/FluxProcessor (Module "deployment.elasticacheclient-1.0.0.jar:main" from Service Module Loader): org/reactivestreams/Processor

以下是导入包在pom.xml中的外观

    <Import-Package>
    org.slf4j;version="1.7.7",javax.net.ssl,javax.security.cert
    </Import-Package>
    <Embed-Dependency>lettuce-core,commons-pool2,netty-transport,netty-common,netty-handler,reactor-core,org.reactivestream</Embed-Dependency>
 <Embed-Transitive>true</Embed-Transitive>

不确定反应堆的OSGI集成是否有问题。

跑了几天马拉松之后，我就能解决这个问题了。原因之一是log4j2 API的版本，因为我使用了更高的版本，但是在版本2.8.2之后，log4j-api.jar文件也包含了为Java9编译的文件，而旧版本的OSGI无法理解拆分包系统。另外，javax包也不是直接从JVM中获取的。我的最后一个pom.xml文件看起来如下：
