初学ssh框架整合小项目--老师学生成绩管理系统
前天学习了关于三个框架的整合，主要spring-hibernate-struts1，因为没学struts2所以暂时是用1做的
一个很简单的项目---老师学生成绩管理系统
先说三个框架的整合：
1.导入三个框架的jar包；
2.拷贝hibernate.cfg.xml文件到SRC目录下，拷贝spring的配置文件applicationContext.xml和struts1的配置文件放入到WEB-INF目录下 <listener>
3.在web.xml文件里加入下面这个监听器
?
?下面是applicationContext
?
?model类和映射的文件包括hibernate的配置文件都可以自动生成还可以用DB反向生成，这里就不放配置文件了。
注：在struts1中的配置文件路径后的type应该是
?
??<action path="/login" type="org.springframework.web.struts.DelegatingActionProxy"parameter="action">
? <forward name="success" path="/welcome.jsp"></forward>
? <forward name="fail" path="/index.jsp"></forward>
? </action>
接下来就是编写业务的代码：service主要是对业务的逻辑处理 ?dao层主要处理数据库 比较简单
主要还是action中
?

1 楼 lxc19881231 2012-06-07 Struts1真麻烦。还是2用的爽。哈哈 2 楼 chenyingjie1001 2012-06-07 lxc19881231 写道Struts1真麻烦。还是2用的爽。哈哈
后面还写了个用2的 感觉还不错 代码清晰很多
