So far the concepts we have discussed are fundamental AOP concepts, not specific to Spring AOP or AspectJ, and already available in Spring 1.x.
迄今为止,我们讨论过的概念都是基本的AOP概念,对于Spring AOP或者AspectJ而且这并不特别,在Spring 1 . x中已经是存在的。
In previous versions HDIV supported Struts 1.x and Struts 2.x, however this release now also supports Spring MVC 2.0 and JSTL.
在以前版本中,HDIV支持Struts 1 . x和struts 2 . x,而本次发布现在也支持Spring MVC 2.0和JSTL。
Partially as a result of the pressure from innovations in Spring, the EJB 3 expert group built a specification describing an interface more like Spring's than EJB 2.x.
在一定程度上由于来自Spring技术革新的压力,导致EJB 3专家小组构建了一个比ejb 2 . x更加相似spring的接口。
Therefore, it'll compress by an unknown x, which is equal to mg divided by the force constant of the spring.
因此它的压缩量为 x,也就等于 mg 除以弹簧的弹性系数
It also tells you that if you compress the spring, compress it means x is now-- x is measured from this position, where the spring is neither compressed nor expanded.
它还能告诉你,如果压缩弹簧,压缩就意味着现在 x...,x 是从这个位置开始算的,在这个位置弹簧既没有压缩也没有伸长
It says, if you pull it to the right, so that x is positive, the spring will exert a force which is in the negative direction; that's why you have a minus sign.
就是说,如果你向右拉,x 取正值,弹簧产生的力方向为负,这就是这里用负号的原因
