Are these technologies/framework complementary to each other? Or they are alternatives to each other (after I use one of them, then I don't need to use the other)?
谢谢.

Spring 是一个 IoC 容器(至少是 Spring 的核心)，用于使用依赖注入来连接事物.Spring 提供额外的服务，例如事务管理和各种其他技术的无缝集成.
Spring is an IoC container (at least the core of Spring) and is used to wire things using dependency injection. Spring provides additional services like transaction management and seamless integration of various other technologies.
Struts is an action-based presentation framework (but don't use it for a new development).
Struts 2 is an action-based presentation framework, the version 2 of the above (created from a merge of WebWork with Struts).
Hibernate is an object-relational mapping tool, a persistence framework.
JavaServer Faces is component-based presentation framework.
JavaServer Pages is a view technology used by all mentioned presentation framework for the view.
Tapestry is another component-based presentation framework.
Struts 2, JSF, Tapestry (and Wicket, Spring MVC, Stripes) are presentation frameworks. If you use one of them, you don't use another.
Hibernate is a persistence framework and is used to persist Java objects in a relational database.
Spring can be used to wire all this together and to provide declarative transaction management.
我不想让事情变得更混乱，但请注意，Java EE 6 提供了与上述框架相当的现代、标准化和非常好的等价物:用于演示的 JSF 2.0 和 Facelets、用于持久性的 JPA 2.0、依赖注入等. 对于新的开发，这是 IMO 一个认真的选择，Java EE 6 是一个伟大的堆栈.
I don't want to make things more confusing but note that Java EE 6 provides modern, standardized and very nice equivalent of the above frameworks: JSF 2.0 and Facelets for the presentation, JPA 2.0 for the persistence, Dependency Injection, etc. For a new development, this is IMO a serious option, Java EE 6 is a great stack.
