Spring
簡介
- The spring-core and spring-beans modules provide the fundamental parts of the framework, including the IoC and Dependency Injection features.
Spring特性： IOC。控制反轉與依賴注入。 AOP。切面編程。 Bean。所有對象都受容器管理，都是一個bean。

Spring 4.0 特性
- 泛型依賴注入
private BaseRepository<M> repository; @Autowired private Repository<User> userRepository; //key是bean名字；value就是所有实现了BaseService的Bean @Autowired private Map<String, BaseService> map; - List注入
这样会注入所有实现了BaseService的Bean；但是顺序是不确定的，如果我们想要按照某个顺序获取；在Spring4中可以使用@Order或实现Ordered接口来实现
@Autowired private List<BaseService> list; - @Lazy可以延迟依赖注入
