How to initialize Application Context in Spring Framework 4
提问by SergeZ
I have a project based on Spring Framework 4and its subproject - Spring Data Solr.
我有一个基于Spring Framework 4及其子项目 - Spring Data Solr 的项目。
All examples I had a chance to see explain how to organize your project - from base entity ( pojo's ) classes till spring specific classes such as repositories and service. When it came to test functionality all examples show a test with private field ( spring bean ) which usually becomes initialized with the help of annotation
我有机会看到的所有示例都解释了如何组织您的项目 - 从基本实体（pojo 的）类到 Spring 特定类，例如存储库和服务。当谈到测试功能时，所有示例都显示了一个带有私有字段（spring bean）的测试，它通常在注释的帮助下初始化
@ContextConfiguration(classes = some-spring-data-main-class.class, loader = SpringApplicationContextLoader.class)
Then it is possible to call for it's bean's methods in @Testmethods.
然后可以在@Test方法中调用它的 bean方法。
But, when it comes to init bean in a project - how to make it with Spring 4, which is completely XMLless ( I mean, I do not have an applicationContext xmlfile ).
但是，当涉及到项目中的 init bean 时 - 如何使用 Spring 4 来实现它，它完全没有 XML（我的意思是，我没有applicationContext xml文件）。
P.S. in Spring 3 we usually wrote smth like:
PS 在 Spring 3 中我们通常这样写：
ApplicationContext context = new ClasspathApplicationContext("applicationContext.xml")
Is it reasonable to expect smth similar to this of Spring 4 introduces absolutely new concepts of application initialization? What should we write now to init app's first bean?
期待与 Spring 4 类似的 smth 引入绝对新的应用程序初始化概念是否合理？我们现在应该写什么来初始化应用程序的第一个 bean？

I got it !
我知道了 ！
In Spring 4 now we have to write:
在 Spring 4 现在我们必须写：
ApplicationContext context = new AnnotationConfigApplicationContext(<out-main-config-class>.class);
and then call for beans and its methods.
然后调用 bean 及其方法。
