java课程设计(通讯录管理系统)

private int id[]; public String message; private boolean success=true; public boolean isSuccess() {
return success; } private ArrayList<Record> list= new ArrayList<Record>(); public ArrayList<Record> getList() {
result.put("success", false); result.put("msg", "login.username.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", "error.user.not.exist"); } else if(list.get(0).getPassword().equals(password)) { result.put("success", true); result.put("msg", "login.success"); } else { result.put("success", false); result.put("msg", "error.password.wrong"); } if((Boolean) result.get("success")) { message = (String) result.get("msg"); return "success"; } else { message = (String) result.get("msg"); return "error"; } } public String getMessage() { return message; } public void setMessage(String message) { this.message = message; }

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。
private static final long serialVersionUID = 1L; public String username; public String password; private String message; @Override public String execute() throws Exception {
（6）具有统计功能
4. 详细设计
4.1 数据结构设计（java 程序设计）
//登录系统 package com.ibm.etp.addressbook.action; import java.util.HashMap; import java.util.List; import com.ibm.etp.addressbook.pojo.User; import com.ibm.etp.addressbook.service.LoginService; import com.opensymphony.xwork2.ActionSupport; public class LoginAction extends ActionSupport {
return username; } public String getPassword() {
return password; } } //删除记录 package com.ibm.etp.addressbook.action;
import java.util.ArrayList; import com.ibm.etp.addressbook.pojo.Record; import com.ibm.etp.addressbook.service.DeleService; import com.opensymphony.xwork2.ActionSupport; public class DeleAction extends ActionSupport {
result.put("success", false); result.put("msg", "login.username.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", "error.user.not.exist"); } else if(list.get(0).getPassword().equals(password)) { result.put("success", true); result.put("msg", "login.success"); } else {
HashMap<Object, Object> result = new HashMap<Object, Object>(); List<User> list = null; System.out.println(username); if(username == null || username.trim().length() == 0) {

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。
（3）系统必须是图形用户界面的形式并连接数据库
return list; } public int getId(int i){
return id[i]; } public int[] getId() {
return id; } public void setId(int[] id) {
public String password; private String message; public String execute() throws Exception {
HashMap<Object, Object> result = new HashMap<Object, Object>(); List<User> list = null; System.out.println(username); if(username == null || username.trim().length() == 0) {
