1）官方网站
在学习一个技术前直到官方网站是极为必要的，官方网站不但提供安装介质，而且有一手的技术参考资料。闲话简说 http://www.springsource.com/。 以前曾用过springframework.org，不知道为什么要改了名字。
2）经典参考书
有人推荐过Spring In Action， 我自己是从Spring Reference开始读的。
3）流行的版本
Spring 2.0, released in October 2006, and Spring 2.5, released in November 2007.
4） Java SE and Java EE Support
The Spring Framework continues to be compatible with all versions of Java since (and including) Java
1.4.2. This means that Java 1.4.2, Java 5 and Java 6 are supported, although some advanced functionality
of the Spring Framework will not be available to you if you are committed to using Java 1.4.2. Spring 2.5
introduces dedicated support for Java 6, after Spring 2.0's in-depth support for Java 5 throughout the
framework.
Furthermore, Spring remains compatible with J2EE 1.3 and higher, while at the same time introducing
dedicated support for Java EE 5. This means that Spring can be consistently used on application servers
such as BEA WebLogic 8.1, 9.0, 9.2 and 10, IBM was 5.1, 6.0, 6.1 and 7, Oracle OC4J 10.1.3 and
11, JBoss 3.2, 4.0, 4.2 and 5.0, as well as Tomcat 4.1, 5.0, 5.5 and 6.0, Jetty 4.2, 5.1 and 6.1, Resin 2.1,
3.0 and 3.1 and GlassFish V1 and V2.
NOTE: We generally recommend using the most recent version of each application server generation. In
particular, make sure you are using BEA WebLogic 8.1 SP6 or higher and was 6.0.2.19 / 6.1.0.9
or higher, respectively, when using those WebLogic and was generations with Spring 2.5.
As of Spring 2.5, support for JDK 1.3 has been removed, following Sun's official deprecation of JDK 1.3 in late
2006. If you haven't done so already, upgrade to JDK 1.4.2 or higher.
If you need to stick with an application server that only supports JDK 1.3, such as was 4.0 or 5.0, we
recommend using the Spring Framework version 2.0.7/2.0.8 which still supports JDK 1.3.
定时器类Timer在java.util包中。使用时，先实例化，然后使用实例的schedule(TimerTask task, long delay)方法，设定指定的任务task在指定的延迟delay后执行。定时器任务类TimerTask是抽象类，继承并重写其run()方法，可实现具体任务。
schedule(TimerTask task, Date time)设定指定任务task在指定时间time执行。

请问各位大位，如果用JAVA来制作动态的个人网站，都需要哪些方面的知识和准备工作？开发工具使用什么比较好，Eclipse还是MyEclipse、还是NetBeans？请高手指教……
以前用Eclipse做过公司的网站，时间隔的有些太久了、都忘记是怎样一个过程了。JSP、SERLET、HIBERNATE� ......
泛型（Generic type 或者generics）是对 Java 语言的类型系统的一种扩展，以支持创建可以按类型进行参数化的类。可以把类型参数看作是使用参数化类型时指定的类型的一个占位符，就像方法的形式参数是运行时传递的值的占位符一样。
可以在集合框架（Collection framework）中看到泛型的动机。例如，Map类允许您向一个Map添 ......
随着多核 CPU 的日益普及，越来越多的 Java 应用程序使用多线程并行计算来充分发挥整个系统的性能。多线程的使用也给应用程序开发人员带来了巨大的挑战，不正确地使用多线程可能造成线程死锁或资源竞争，导致系统瘫痪。因此，需要一种运行时线程监控工具来帮助开发人员诊断和跟踪 Java 线程状态的切换。JDK 1.5 及其后续版� ......
