In short: Blueprint is a specification, Spring DM is an implementation of Blueprint API

blocks|key|1046818|text|蓝图是在SpringSource/Interface21的领导下在OSGi联盟中开发的。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1046819|但是，如果您正在寻找一种利用OSGi的方法，可以使用声明性服务(DS)在包(服务)之间进行注释。根据我的经验，当您制作小的内聚包时，并不真正需要连接XML。与Blueprint/Spring相比，DS在处理服务方面要好得多，因为他们倾向于“隐藏”动态性，而DS只会使其简单易用。|1046820|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

Blueprint was developed in the OSGi Alliance under the lead of SpringSource/Interface21. 

However, if you're looking for a way to leverage OSGi use Declarative Services (DS) with annotations between bundles (services). In my experience, you do not really need the wiring XML when you make small cohesive bundles. DS is much better in working with services than Blueprint/Spring DM since they tend to to want to "hide" the dynamicity while DS just makes it trivial to use.

blocks|key|515604|text|我的理解是SpringDM是一个死掉的项目。检查GA和发布日期。因此，尽管它对规范的开发做出了很大贡献，但最终它对类加载器却有一种糟糕的方法。阿帕奇-白羊座是一个强大的蓝图实现。请注意，使用图纸并不排除使用弹簧。我建议卡拉夫作为一个健壮的平台，可以将日蚀均分或阿帕奇费利克斯用于OSGI引擎。如果您是在应用程序级别开发，您的服务可能被企业内的其他团队或组织使用，或者由您的客户扩展，我喜欢蓝图与DS。我认为蓝图也更适合传统的企业计算环境。但是，根据特定的目标环境，DS或伊波霍可能更合适。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|515605|entityMap|0|LINK|mutability|MUTABLE|url|http://www.springsource.org/osgi/|1|http://aries.apache.org/|2|http://karaf.apache.org/|3|http://www.eclipse.org/equinox/|4|http://felix.apache.org/|5|http://felix.apache.org/site/apache-felix-ipojo.html^0|5|G|0|1Z|7|1|31|3|2|3H|4|3|3M|7|4|6J|3|5|0^^$0|@$1|2|3|4|5|6|7|V|8|@]|9|@$A|W|B|X|1|Y]|$A|Z|B|10|1|11]|$A|12|B|13|1|14]|$A|15|B|16|1|17]|$A|18|B|19|1|1A]|$A|1B|B|1C|1|1D]]|C|$]]|$1|D|3|-4|5|6|7|1E|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]|L|$5|G|H|I|C|$J|M]]|N|$5|G|H|I|C|$J|O]]|P|$5|G|H|I|C|$J|Q]]|R|$5|G|H|I|C|$J|S]]|T|$5|G|H|I|C|$J|U]]]]

My understanding is that <a href="http://www.springsource.org/osgi/" rel="noreferrer">SpringDM is a dead project</a>. Check the GA and release dates. So although it contributed much to the development of the specification in the end it had a bad approach to classloaders. <a href="http://aries.apache.org/" rel="noreferrer">Apache-Aries</a> is a strong blueprint implementation. Note that use of blueprint does not preclude use of spring. I would suggest <a href="http://karaf.apache.org" rel="noreferrer">Karaf</a> as a robust platform that can use either <a href="http://www.eclipse.org/equinox/" rel="noreferrer">Eclipse Equinox</a> or <a href="http://felix.apache.org" rel="noreferrer">Apache Felix</a> for the OSGI engine. I like blueprint versus DS if you are developing at the application level where your services may be used by other teams or organizations within your enterprise, or extended by your customers. I think blueprint is also a better fit for traditional enterprise computing environments. But DS or <a href="http://felix.apache.org/site/apache-felix-ipojo.html" rel="noreferrer">Ipojo</a> may be more appropriate depending on your particular target environment.

blocks|key|568087|text|除了Dmytro+Pishchukhin的回答之外，还应该注意到Spring项目在某种程度上是一个死掉的项目，因为DM+2从未达到“发布”版本。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|568088|取而代之的是为Eclipse基金会做出贡献，它在那里变异为双子座蓝图计划。|offset|length|568089|entityMap|0|LINK|mutability|MUTABLE|url|http://www.springsource.org/osgi|1|http://www.eclipse.org/gemini/blueprint/^0|0|6|F|0|T|7|1|0^^$0|@$1|2|3|4|5|6|7|P|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|Q|8|@]|9|@$D|R|E|S|1|T]|$D|U|E|V|1|W]]|A|$]]|$1|F|3|-4|5|6|7|X|8|@]|9|@]|A|$]]]|G|$H|$5|I|J|K|A|$L|M]]|N|$5|I|J|K|A|$L|O]]]]

In addition to what Dmytro Pishchukhin answered, it should be noted that the Spring DM project is somewhat a dead project, as DM 2 never reached a "release" version. 

Instead it was <a href="http://www.springsource.org/osgi">contributed to the Eclipse foundation</a> where it mutated into the <a href="http://www.eclipse.org/gemini/blueprint/">Gemini Blueprint project</a>.

blocks|key|515615|text|在双子座蓝图文档的介绍中，他们清楚地解释了区别：http://www.eclipse.org/gemini/blueprint/documentation/reference/1.0.2.RELEASE/html/index.html|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|515616|我在这里复制：|515617|第1章.+Spring动态模块成为Eclipse双子座蓝图
2009年底，作为Gemini项目提案的成员，SpringSource向Eclipse提供了(也称为Spring+)项目。Spring+v2代码库已与其问题跟踪器和论坛一起转移到Eclipse.org。该项目在Apache许可和EPL下获得了双重许可。
虽然名称已经更改，但代码及其功能保持不变。正如迁移指南中提到的，现有的Spring应用程序可以很容易地迁移到。|blockquote|515618|entityMap|0|LINK|mutability|MUTABLE|url|http://www.eclipse.org/gemini/blueprint/documentation/reference/1.0.2.RELEASE/html/index.html^0|O|2L|0|0|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@$A|R|B|S|1|T]]|C|$]]|$1|D|3|E|5|6|7|U|8|@]|9|@]|C|$]]|$1|F|3|G|5|H|7|V|8|@]|9|@]|C|$]]|$1|I|3|-4|5|6|7|W|8|@]|9|@]|C|$]]]|J|$K|$5|L|M|N|C|$O|P]]]]

In the introduction of the Gemini Blueprint documentation they explain clearly the difference :
<a href="http://www.eclipse.org/gemini/blueprint/documentation/reference/1.0.2.RELEASE/html/index.html" rel="nofollow">http://www.eclipse.org/gemini/blueprint/documentation/reference/1.0.2.RELEASE/html/index.html</a>

I reproduce here :

<blockquote>
 Chapter 1. Spring Dynamic Modules becomes Eclipse Gemini Blueprint
 
 In late 2009, as a member of the Gemini project proposal, SpringSource contributed Spring Dynamic Modules (also known as Spring OSGi) project to the Eclipse Foundation. Spring DM v2 code base has been moved to Eclipse.org along with its issue tracker and forum. The project became dual licensed under Apache License and EPL.
 
 While the name has changed, the code and its functionality remained the same. Existing Spring DM applications can be easily migrated to Eclipse Gemini Blueprint as mentioned in the migration guide.
</blockquote>

I am a little bit confused about Blueprint and Spring DM: 

From what I think is true:

<ul>
<li>Spring DM is a framework defined by Spring Source</li>
<li>Blueprint is a framework defined by the OSGi Alliance</li>
<li>Blueprint has "taken" many of it's ideas from Spring DM</li>
</ul>

No?

Can we expect that those two frameworks become one in the future (merge)? If not, which one will be the most future-proof?

我对蓝图和Spring有点困惑：在我看来是真的：Spring是Source定义的一个框架蓝图是OSGi联盟定义的框架蓝图“采纳”了Spring的许多想法不是吗？我们能期待这两个框架在未来成为一个(合并)吗？如果不是，哪一个将是最能证明未来的？
