osgi+camel+karaf运行环境搭建(2)

本文开始osgi运行环境后续搭建,上文介绍了几个运行组件与容器,本文将开始具体的代码编写。


root module

打开intellij新建maven工程,待maven工程全部生成完成之后,在pom.xml中添加以下内容。

以上均是搭建环境所必须的相关依赖,因为本环境并不仅仅是进行几个osgi的example的编写,因此搭建环境比较复杂。在以上依赖添加完之后,还需要将pom.xml中的packaging改为pom,并且删去工程下的src文件夹,本工程为root模块,不需要写代码。


parent module

新建maven module为当前工程的子module,命名为parent,与上述module相同的是,parent同样是一个父module,因此删除目录下src文件夹,仅保留pom.xml,同时在pom.xml中添加如下内容:

        <docker.base.version>1.1.4</docker.base.version>

    </properties>

                    <execution>

                        <goals>
                            <goal>install</goal>

            </plugin>
        </plugins>
    </build>

</project>

以上基本就是我们当前需要添加的所有依赖,在当前还添加了个别项目中的模块,这些是在后续中将添加的,当前报错的地方可以先注释起来。

并且注意maven插件中的karaf-tooling这一个插件,这个就是提供osgi的运行容器karaf,在后文的编写中,这个将起到非常重要的作用,同时maven-resources-plugin这一个插件管理我们项目中其他资源的位置,在日后的编写中也将会提到这个。当然上文中也必少不了felix这一个插件,在后文中编写felix官网中的example时,这个将不时出现。


feature module

再次在root module下新建maven工程,命名为feature module,这一个尤其重要,这个module中,将对具体的feature进行管理,feature是一批bundle的集合,同时也在管理接下来中的子module中所需的其他feature依赖和bundle。

管理这些feature需要一个单独的xml配置文件,删除src下的main文件夹,保留resource文件夹,新建xml命名为feature.xml,添加以下内容:

<?xml version="1.0" encoding="UTF-8"?>
<features name="karaf-swagger-${project.version}"
          xmlns="http://karaf.apache.org/xmlns/features/v1.0.0"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://karaf.apache.org/xmlns/features/v1.0.0
        http://karaf.apache.org/xmlns/features/v1.0.0">

</features>

现在这个feature.xml中没有管理任何featue,在后文中将会添加其他featue进来。现在是最基本的配置。

在新建完feature之后,在pom文件中添加以下内容:


    <properties>
        <deploy.file>${project.build.directory}/classes/features.xml</deploy.file>
    </properties>

    <build>
        <defaultGoal>install</defaultGoal>

        <resources>
            <resource>
                <directory>src/main/resources</directory>

            </resource>
        </resources>

                    <execution>
                        <id>filter</id>

            <plugin>

                <executions>

                        <goals>
                            <goal>attach-artifact</goal>
                        </goals>
                        <configuration>
                            <artifacts>
                                <artifact>
                                    <file>${deploy.file}</file>
                                    <type>xml</type>
                                    <classifier>features</classifier>
                                </artifact>
                            </artifacts>
                        </configuration>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

</project>

以上内容是指定feature.xml文件位置以及相应对该文件进行操作的插件,在以上完成之后,需要改当前pom的parent为parent module,同时在parent module中添加module为feature。


总结

以上完成之后,基本的环境搭建基本就完成了,具体的编码module的创建,还有karaf输出日志的的规定,将在下次博文中编写,本文仅只搭建基本的运行环境。

osgi+camel+karaf运行环境搭建(1)

这几天一直在学习与加深osgi中的一些东西,又去看了下apache felix中的几个example,于是决定将felix中的一些example写出来,但是不在使用felix官网中那样运行,而是从新搭建一个osgi的运行环境进行相应的学习,在这使用了karaf作为osgi的运行容器,同时整合camel进来,因为在后续会有更多的osgi中的运用,因此,本次全部整合进来. 本文在此先对几个框架和容器进行相应介绍. karaf Karaf是2001年Apache旗下的一个开源项目.Karaf同时也是一
