apache-camel - 为什么 Aries Blueprint 没有为 camel-cxf 和 camel-blueprint 注册命名空间处理程序？

Camel 2.23.1 Karaf 4.2.4

白羊座蓝图(用于注册所有内容的外部容器)
Camel 蓝图(用于 Camel 路线)
Camel CXF(用于 rsServer)
CXF 核心(用于访问 CXF 总线属性)

XML 命名空间

<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xmlns:cxf="http://camel.apache.org/schema/blueprint/cxf"
           xmlns:cxfcore="http://cxf.apache.org/blueprint/core"
    xsi:schemaLocation="
            http://www.osgi.org/xmlns/blueprint/v1.0.0 http://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd
            http://camel.apache.org/schema/blueprint http://camel.apache.org/schema/blueprint/camel-blueprint-2.23.1.xsd

            http://cxf.apache.org/blueprint/core http://cxf.apache.org/schemas/blueprint/core.xsd"

错误蓝图命名空间处理程序:

Status: GracePeriod
Declarative Services
Blueprint
12.04.19, 09:00
Missing dependencies:
(&(objectClass=org.apache.aries.blueprint.NamespaceHandler)(osgi.service.blueprint.namespace=http://camel.apache.org/schema/blueprint/cxf)) (&(objectClass=org.apache.aries.blueprint.NamespaceHandler)(osgi.service.blueprint.namespace=http://camel.apache.org/schema/blueprint))

综上所述，Aries Blueprint 未注册以下内容:

The blueprint runtime does not parse the blueprint xml until NamespaceHandler services can be found for every custom namespace that is used in the bundle. Unless NamespaceHandler services can be found for every custom namespace, the blueprint container is unable to process the bundle. This result can mean that the blueprint container waits indefinitely if no NamespaceHandler exists. https://www.ibm.com/support/knowledgecenter/en/SSEQTP_liberty/com.ibm.websphere.wlp.doc/ae/rwlp_blueprint_namespace_handler.html

由于这些 karaf.log 条目，我知道 Aries Blueprint 正在运行并注册了一些命名空间:

Karaf:如您所见，My Awesome Application 卡住了(可能陷入循环)

关于 HttpServer 出现了另一个间歇性错误。

java.lang.ClassNotFoundException: org.osgi.service.http.HttpService not found by org.apache.cxf.cxf-rt-transports-http

我的第一个想法是，这是命名空间处理程序验证命名空间所必需的，但是完全删除 karaf 并重新安装所有内容并不总是会产生此错误。事实上，我得到:

Bundle is waiting for namespace handlers [http://camel.apache.org/schema/blueprint]

最佳答案

重要的是，Aries 蓝图 (blueprint-core) 和 Aries Blueprint API (blueprint-api) 未声明为嵌入在 MANIFEST.MF 中。使用 maven-bundle-plugin 时，这相当于查看 pom.xml

<Embed-Dependency>
   *
</Embed-Dependency>

这里的星号包括，例如，blueprint-core、blueprint-api、camel-core、blueprint -蓝图。这可能导致 Karaf 在查找 namespace 处理程序时检查错误的 namespace 注册表。

我只是删除了 Kleene star * 并仅嵌入了我需要的非 OSGI 包。但是，如果你想要一个星星，那么也有一个解决方案。因为 Embed-Dependency 是按顺序(自上而下)处理的，所以可以像这样排除星号之前的依赖:

<Embed-Dependency>
   !org.apache.aries.blueprint-core,
   !org.apache.aries.blueprint-api,
   *
</Embed-Dependency>

星标将不包含预先否定的包。

此外，可能是 features.xml 中声明的两个 Karaf 特性启动了多个 CXF 实例，即特性 camel-cxf 和 feature cxf，这可能会导致其中只有一个注册到蓝图命名空间处理程序。

关于apache-camel - 为什么 Aries Blueprint 没有为 camel-cxf 和 camel-blueprint 注册命名空间处理程序？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/55646436/
