你是需要这样的代码吗?

你是需要B/S模式的还是C/S模式的?
这些功能写起来比较简单,在后台连个数据库,做些数据的处理就可以了。不过要我这没有现成的,要自己的写的话估计没有时间了。如果你是在学习java的话,建议你自己动手写写,这个小系统能用到好多东西。
简单点的话直接用JDBC边数据库,要是好点可以考虑使用Hibernate,如果写成B/S模式的话,还可以考虑使用一些MVC的框架,struts或者spring,前台还能使用到ajax.当然,你还需要打印报表的功能,这个也是一个难点。
java管理系统怎么实现用户不同,看到的模块也不同,增加,删除,修改的权限也不同 求代码 java java java
代码。
你这个代码很大啊,管理系统。
不知道是javaweb的 还是就是java写的一个图形界面程序?
给你一个思想。
登陆上选择不同的身份,提供不同的值,判断不同的值就可以进行不同的显示效果。
权限最大的就可以利用 type==这个值||type==这个值就可以显示这个界面。
web 的话就是OGNL语言使用
图形界面也差不多。
