我可以在karaf(任何特定文件夹)中放置第三方jar来解决传递依赖吗？

Question

我有各种自制项目,具有第三方库依赖项.我将它们捆绑为OSGI容器但无法解决我的项目中的深度依赖项.现在我正在寻找karaf文件夹,我可以放置我的库,所以捆绑可以直接访问它们而不是安装它们.

更多我正在使用maven.

编辑:在遵循你的'功能'解决方案后,我能够产生明显的传递依赖性,但问题是现在它也寻找非常常见的java文件:例如:下面是相当大的依赖列表:

回答你的问题:你可以将所有依赖包都删除到$ KARAF_HOME/deploy文件夹中,然后Karaf会为你部署它们.

但是,这不是很方便,因为它是一个手动过程而不是由Maven驱动.而是看看Karaf的功能存储库概念.您可以使用Karaf maven插件为捆绑包及其(传递)依赖项创建功能存储库.如果需要将应用程序作为单个工件发送,则可以使用相同的插件创建KAR存档,该存档是一个zip文件,其中包含功能存储库和自包含部署单元中所需的依赖项.

要开始,请将模板feature.xml文件放入src/main/feature:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<features xmlns="http://karaf.apache.org/xmlns/features/v1.3.0" 
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://karaf.apache.org/xmlns/features/v1.3.0 http://karaf.apache.org/xmlns/features/v1.3.0"
        name="My feature">
    <feature name="${project.artifactId}" version="${project.version}" description="Describe feature here">
         <!-- Add "self" to the list of dependencies -->
         <bundle>mvn:${project.groupId}/${project.artifactId}/${project.version}</bundle>
    </feature>
</features>

然后设置插件以根据您的maven依赖项填充功能模板:

<plugin>
    <groupId>org.apache.karaf.tooling</groupId>
    <artifactId>karaf-maven-plugin</artifactId>
    <configuration>
        <includeTransitiveDependency>true</includeTransitiveDependency>
    </configuration>
    <executions>
        <execution>
            <id>generate-features-descriptor</id>
            <goals>
                <goal>features-generate-descriptor</goal>
            </goals>
        </execution>
    </executions>
</plugin>

构建项目将在本地maven存储库中与您的bundle jar一起创建一个额外的maven工件:xxx-features.xml您可以使用该feature:repo-add命令使本地Karaf知道您的功能存储库.然后使用该feature:install命令添加您的功能.这将启动您的bundle及其所有声明的(传递的)Maven依赖项.

编辑:

当你在评论中提到,在某些(所有？)你的依赖是普通JAR文件,而不是OSGi包,可能是你最好嵌入这些非OSGi的依赖到你自己的捆绑使用Maven束的插件.但这可能非常繁琐.大多数非OSGi JAR都具有在运行时根本不使用的包导入,或者在特定使用方案中未使用的包导入.要避免吹起来的OSGi的依赖列表超出你传递Maven依赖的名单,你就必须防止这些"继承"包被添加到包进口清单在自己的包的清单.例如,我有一个使用httl模板库的bundle,它再次依赖于Javassist.OSGi捆绑包也不是.所以我嵌入了两个并禁止导入在httl或javassist代码中声明但在运行时不需要的包:

<plugin>
    <groupId>org.apache.felix</groupId>
    <artifactId>maven-bundle-plugin</artifactId>
    <extensions>true</extensions>
    <configuration>
        <instructions>
            <Embed-Dependency>*;scope=compile|runtime;inline=false;artifactId=httl|javassist</Embed-Dependency>
            <Embed-Transitive>false</Embed-Transitive>
            <Import-Package>
                !com.alibaba.*,
                !com.thoughtworks.*,
                !javassist.*,
                !net.htmlparser.*,
                !org.apache.commons.logging.*,
                !org.codehaus.jackson.*,
                !org.joda.convert.*,
                !com.sun.jdi.*,
                !javax.servlet.*,
                *
            </Import-Package>
        </instructions>
    </configuration>
</plugin>
