三. 总体设计
3.1 系统总体功能框架图
通讯录管理系 统
登录
系 统 管 理
注册新用户
用户数据增添功能 用户数据查询功能 用户数据删除功能 用户数据统计功能
录入数据库
全部查询 按条查询
3.2 系统功能说明
退出系统
（1）具有新用户注册功能。 （2）具有注册用户登录功能。 （3）具有数据的录入功能。 （4）具有数据查询功能，可以实现查询全部信息和按条件执行查询。 （5）具有按条件删除数据功能。
result.put("success", false); result.put("msg", "ername.empty"); } else if(password == null || password.trim().length() == 0) { result.put("success", false); result.put("msg", "login.password.empty"); } else { LoginService ls = new LoginService(); list = ls.checkLogin(username); } if(list == null) { result.put("success", false); result.put("msg", "er.not.exist"); } else if(list.get(0).getPassword().equals(password)) { result.put("success", true); result.put("msg", "login.success"); } else {
private static final long serialVersionUID = 1L; public String username; public String password; private String message; @Override public String execute() throws Exception {
return list; } public int getId(int i){
return id[i]; } public int[] getId() {
return id; } public void setId(int[] id) {
一． 设计题目
随着社会的进步与发展，通讯越来越密切。希望能通过对 java 课程设计的 学习和掌握来编写一个通讯录管理系统。
二．设计要求
（1）只能使用 Java 语言，采用面向对象方法进行设计，要求源程序要有适当 的注释，使程序容易阅读。 （2）程序必须与数据库进行通信。
