project-reactor - 通过 wildfly 10 使用 elasticache 的生菜 6.0.2（为 OSGI 部署定制）

Question

我正在尝试将生菜 6.0.2 部署在连接 AWS elasticache 的 Wildfly 10（定制为部署 OSGI 包）上。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 wildfly 上部署时，它在调用时出现以下错误：RedisClusterClient.create(redisURI);

原因：org.apache.felix.log.LogException: java.lang.NoClassDefFoundError: javax/net/ssl/SSLParameters ... 42 更多原因：java.lang.ClassNotFoundException: javax.net.ssl.SSLParameters from [Module来自服务模块加载器的“deployment.elasticache-1.0.0.jar:main”]

pom.xml 具有以下依赖项：

由于 javax.net.ssl 是 JDK 8 的一部分，为什么它在与 wildfly-10 一起部署时不可用。为了加快响应时间，我在生菜组问了同样的问题。

更新：

经过几次调整后，原始错误消失了。但是 OSGI 仍然无法部署反应器 API，现在我收到以下错误：

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

这是导入包在 pom.xml 中的样子

    <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>

不确定反应器的 OSGI 集成是否存在问题。

Answer 1

跑了几天马拉松后，我能够解决这个问题。原因之一是 log4j2 API 的版本，因为我使用的是更高版本，但是在 2.8.2 版本之后，log4j-api.jar 文件也包含为 Java 9 编译的文件，并且旧版本的 OSGI 无法理解分包系统。不知何故，javax 包也不是直接取自 JVM。我的最终 pom.xml 文件如下所示：
