将现有的java项目转换为osgi包的最佳方式

当使用maven-bundle-plugin时,您可以设置扩展名和supportedProjectTypes,因为您可能会遇到CI构建问题,如果包装类型为bundle,则Maven repos和m2e将失败(请参阅end).

在早期测试您最有风险/核心的外部依赖关系 – 例如,如果您使用JPA进行持久化,那么请确保提供程序在具有域绑定和JDBC驱动程序的OSGi环境中工作.

如果您从Java EE / Spring迁移,请查看Karaf或Virgo.但是,如果您的组件用于嵌入式系统或没有外部依赖关系,那么Felix或Equinox可能就足够了(如果是这样,请检查pax-url项目).

可能值得编辑您的问题,以更具体的域/技术？

eclipse：eclipse仅在项目首次配置时生成,m2e的生命周期问题可能会有点痛苦,但远远优于使用旧的eclipse插件.

以下将添加清单条目到您现有的工件,而不用任何其他方式更改它们.它告诉标准的maven jar和war插件来使用由maven-bundle-plugin生成的MANIFEST.MF.

把它放在父POM中：

<pluginManagement>
<plugin>
    <groupId>org.apache.felix</groupId>
    <artifactId>maven-bundle-plugin</artifactId>
    <version>2.3.7</version>
    <extensions>true</extensions>
    <configuration>
        <archive>
            <addMavenDescriptor>true</addMavenDescriptor>
        </archive>
        <supportedProjectTypes>
            <supportedProjectType>jar</supportedProjectType>
            <supportedProjectType>war</supportedProjectType>
        </supportedProjectTypes>
        <instructions>
            <Built-By>${project.organization.name}</Built-By>
            <Bundle-Vendor>${project.organization.name}</Bundle-Vendor>
            <Bundle-ContactAddress>${project.organization.url}</Bundle-ContactAddress>
            <Bundle-Description>${project.description}</Bundle-Description>
            <Bundle-DocURL>${bundle.doc.url}</Bundle-DocURL>
            <Bundle-Category>${bundle.category}</Bundle-Category>
            <Bundle-SymbolicName>${project.artifactId}</Bundle-SymbolicName>
            <Bundle-Version>${project.version}</Bundle-Version>

            <Import-Package>*</Import-Package>
            <Export-Package>*</Export-Package>
        </instructions>
    </configuration>
    <executions>
        <execution>
            <id>bundle</id>
            <goals>
                <goal>manifest</goal>
            </goals>
            <phase>prepare-package</phase>
            <inherited>true</inherited>
        </execution>
    </executions>
</plugin>

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-jar-plugin</artifactId>
    <version>2.3.1</version>
    <configuration>
        <archive>
            <manifestFile>${project.build.outputDirectory}/META-INF/MANIFEST.MF</manifestFile>
        </archive>
    </configuration>
</plugin>

<plugin>
    <artifactId>maven-war-plugin</artifactId>
    <version>2.1.1</version>
    <executions>
        <execution>
            <id>create-war</id>
            <phase>package</phase>
            <goals>
                <goal>war</goal>
            </goals>
            <inherited>true</inherited>
        </execution>
    </executions>
    <configuration>
        <archive>
            <manifestFile>${project.build.outputDirectory}/META-INF/MANIFEST.MF</manifestFile>
        </archive>
    </configuration>
</plugin>
</pluginManagement>

然后在孩子POM中,你可以简单地做：

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.felix</groupId>
            <artifactId>maven-bundle-plugin</artifactId>
        </plugin>
        <!-- Below is mutually exclusive: Either jar or war plugin -->
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-jar-plugin</artifactId>
        </plugin>
    </plugins>
</build>
