spring的优缺点

Question

请问spring这个框架有哪些优缺点?

Answer 1

会struts吗  会hibernate吗？spring的作用就是帮你吧这些不相关框架整合在一起  方便开发

Answer 2

为什么你会觉得Spring开发周期和成本高? 请给出具体理由
Spring本来就是为了提高开发效率为目标的
不能因为自己不会用,就说别人的东西不好用啊...

Answer 3

网上一搜一大堆,自己找找有很多比较专业的对spring的介绍,不过要切身感受其强大还要用起来. 可能我开发时间不久,我想象不出来如果没有spring,web开发是什么样子的

Answer 4

优点肯定是IOC,我是一直不喜欢spring,什么都给配好了,像我这样的新手想知道原理和思路很难,公司自己的框架就是借鉴spring的很多地方,自学和理解都很不错

Answer 5

    Spring是分层的架构，你可以选择使用你需要的层而不用管不需要的部分
    Spring是POJO编程，POJO编程使得可持续构建和可测试能力提高
    依赖注入和IoC使得JDBC操作简单化
    Spring是开源的免费的
    Spring使得对象管理集中化合简单化

Answer 6

优点就是他的核心  IOC  AOP缺点，非要深究我只能表示在追求极限访问速度上，不如servlet，毕竟他使用了大量的反射
