Since the open source project began in February, 2003, the Spring Framework has gone from strength to strength. It has powered past 1 million downloads; become a de facto standard in a wide range of industries; and changed the development of enterprise Java applications.Most important, it has developed a large and loyal user base, which understands its key values and has contributed feedback that has helped it to advance rapidly. Spring's mission always been clear:
To provide a non-invasive programming model. As far as possible, application code should be decoupled from the framework.
To provide a superior solution to in-house infrastructure, so that developers can focus on delivering business value rather than solving generic problems.
To make developing enterprise applications as simple as possible, but enhancing, rather than sacrificing, power.
　　　Spring 2.0, which went final in October, 2006, further advances these values. As the core team looked at the development feature set coming together before the December 2005 Spring Experience Conference in Florida, we realized that two key themes - Simplicity and Power - stood out as a the common thread in Spring 2.0, and remained faithful to Spring's beginnings.
　　　Some decisions were easy. From the outset, we were clear that Spring 2.0 was going to be fully backward compatible, or as near to fully backward compatible as possible. Especially given Spring's position as a de facto standard in many enterprises, it was vital to avoid any disruption in user experience. Fortunately, because Spring has always gone to such pains to be non invasive, this goal was achievable.


　　　從2003年2月開(kāi)源工程開(kāi)始以來(lái)，Spring框架已經(jīng)變得越來(lái)越強(qiáng)大了。它已經(jīng)給過(guò)去一百萬(wàn)下載提供動(dòng)力；成為一個(gè)在大范圍的工業(yè)個(gè)范圍中實(shí)際的標(biāo)準(zhǔn);并且改變企業(yè)Java語(yǔ)言應(yīng)用的發(fā)展。最重要的是，它已經(jīng)發(fā)展了一個(gè)大和忠誠(chéng)的，懂得它的重要價(jià)值和已經(jīng)幫助它迅速前進(jìn)的反饋意見(jiàn)的用戶基礎(chǔ)。Spring的任務(wù)總是清楚：
提供一個(gè)非侵害的編程模型。只要可能,在框架中應(yīng)用代碼是應(yīng)該很少的。
向機(jī)構(gòu)內(nèi)部基礎(chǔ)提供上級(jí)解決方案，因此開(kāi)發(fā)者能關(guān)注商業(yè)價(jià)值不是解決普通的問(wèn)題。
使開(kāi)發(fā)企業(yè)應(yīng)用程序變得盡可能簡(jiǎn)單，是增強(qiáng)而不是削弱開(kāi)發(fā)力量。

一些決定是很容易的。從一開(kāi)始，我們很清楚Spring 2.0是完全向后兼容的，或者盡可能向后兼容靠近完全。尤其是給Spring的是一個(gè)在很多企業(yè)中實(shí)際的標(biāo)準(zhǔn)的地位，它是
