电子教务系统java代码 java教务系统源代码

求一个教务管理系统的java程序,有学生,管理员,教师三种身份,告诉我怎么让它跑起来啊!!急!!!

- -没看明白,什么叫做让他跑起来,如果三种身份的话呢,你可以做三个不同的全局变量或参数,在你用其中一种身份登录时,所对应的参数也被代入进去,我是不懂来着。。。

跪求教务管理系统java源代码,可以在myeclipse上运行的,要求连接数据库,发这个号1048550695

不要在知道上求这种源码了。。。百度积分50分,换算人民币,都可以忽略不计的,津巴布韦币都比这值钱。

也就是说,其实你是在索求免费的源码。

如果是索求免费的源码,那么你应该去开源论坛或开源网站去找,而不是来百度知道。

java怎么通过代码登入教务系统

我使用几系统都B/S结构每登录都需要输入用户名密码觉非麻烦考虑其同事需求妨写自登录程序吧前考虑使用单点登录几经尝试放弃

我习惯使用Java本能始寻找Java解决Google输入Java自登录、Java网页模拟登录、Java Post 登录结倒少内容差我尝试终究没达我预期目标我都知道些代码应该jsp页面执行c/s结构程序执行些代码确实管用

我先析代码

String surl = "";

URL url = new URL(surl);

URLConnection conn = url.openConnection();

conn.setDoOutput(true);

OutputStreamWriter out=new OutputStreamWriter(conn.getOutputStream());

String str = "username=yournamepassword=123456";

out.write(str);

out.flush();

out.close();

C/S结构且参数确程序能够功登录oa系统要看结通面代码系统服务器返结System.out.println()

String sling = "";

String scontent = "";

BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream(),"UTF-8"));

while ((sling = in.readLine()) != null)

scontent += in + "\r\n";

System.out.println(scontent);

C/S结构控制台输返值返内容看程序已经功登录要网址浏览器打重新登录问题没根本解决恶意注册应该达目

看C/S结构容易实现网页程序自登录除非C/S程序内嵌浏览器直接浏览器自访问系统应该没别主要问题于我没办共享Session

便于共享Session我能浏览器实现网页自登录通面代码jsp页面测试达预期目标

网页自登录希望程序自填充用户名密码Post式提交给登录页面Form所指向action页面或我系统登录页面源代码保存网页usernamepassword文本框设置默认值通网页登录系统测试发现行接能已经想解决

我通url.openConnection()建立连接返scontent打印接着打印代码:

out.println("\r\n");

原理简单通login.jsp登录页面全部源代码写前页面使用javascript脚本用户名密码值填充提交表单终于实现自登录目标现我通特殊网址例自访问oa

能注意参数url值经加密内容用户名密码加效期即效期内链接才效才实现自登录

java编写个教务系统,控制台输出。

这个还是你自己写吧,又不难。建两张数据表,一个用户表,一个课程表,用户表里面弄一个字段控制相应权限就成。
