当前位置 博文首页 > 莫忘、初心：karaf + osgi +maven 框架搭建
配置环境:
maven:3.6
jdk:1.8
首先我们需要新建一个总项目,此项目里面没有任何的代码,只是在pom文件中进行版本控制
新建项目的时候不需要选择任何的框架,需要的时候再添加依赖和插件即可
注意karaf项目是需要继承apache-karaf-examples的,要不然会产生很多不必要的坑,解决起来很耗费时间’
apache-karaf-examples实际上是官方出的实例
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<parent>
<groupId>org.apache.karaf.examples</groupId>
<artifactId>apache-karaf-examples</artifactId>
<version>4.2.3</version>
</parent>
<groupId>com.karaf.osgi</groupId>
<artifactId>karaf-osgi</artifactId>
<version>1.0.0</version>
<packaging>pom</packaging>
<name>Karaf :: Osgi</name>
<modules>
<module>karaf-osgi-features</module>
</modules>
</project>
现在让我们来新建一个feature子项目来管理osgi的bundle
为了显得专业一些,我们把src/main下方的java文件夹删除,resource修改为feature
在feature文件夹下新建xml为feature.xml,
feature.xml内容如下:
注意标签features 中的name值
<?xml version="1.0" encoding="UTF-8"?>
<features name="karaf-osgi-${project.version}" xmlns="http://karaf.apache.org/xmlns/features/v1.4.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://karaf.apache.org/xmlns/features/v1.4.0">
</features>
feature服务的pom文件配置如下,我们要配置下feature.xml的路径,在下方build标签内添加resource
<resources>
<resource>
<directory>src/main/feature</directory>
<filtering>true</filtering>
<targetPath>${project.build.directory}/feature</targetPath>
</resource>
</resources>
在下方插件build-helper-maven-plugin中的标签artifact内配置feature.xml的相对路径
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
