本文主要是介绍winter framework 源码 SSH最精简的实现,希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!
前些天一直在写这个框架,现在放出源码!主要功能:
1、自动将表单封装成对象(类似Struts2)
2、自动根据对象产生增删改查sql语句(类似hibernate)
3、支持Spring动态注入,可以把自定义的Action 交给Spring去进行管理
4、自定义的tab标签库
5、支持伪静态功能
伪静态实现,可以用正则表达式!~
这个框架,差不多就是一个SSH最精简的实现。
配置非常灵活简单,比起三大框架来说,容易多了,而且包就一个而已,非常的小!
包和类:
org.pan.code 这是核心类的包
主要的类:
过滤器-转发控制器-Action管理器-字段类型转换器-Spring支持类-JDBC支持类-SQL创建类
主要的配置文件是:request.xml
