Flex & iBatis &Hibernate &Spring—师徒奶茶系统V1总结
昨晚只睡了两个小时来改进这个属于我们“下午茶”师徒群的同学们。主要是用Flex做前端，Java做后台。其实整个系统搭建起来很容易，因为Flex&Java应该说是我最熟悉的吧。为了快速和友好的交互，当然还是用这个。不过这次比较傻的是，前几天实现的用户列表的增删查改是用iBatis，主要原因是想基于以前一个简单的测试项目，前面几篇博文中有详细的介绍。可是，昨晚抽风又想用Hibernate了。这样就是说我需要两个信道“AMF”和“RTMP”。所以就会出现一些问题。不过还好，最后发现问题应该是AMF信道的配置。Channel当时临时写在了客户端代码里面。其实应该写在一个properties或者xml文件中去读取的。好了吧。废话不多说。上代码。首先是客户端代码。主要的AS:
