DWR简单 实现单向聊天【文章三：业务层、控制层、bean】 功能登录显示登录用户【无数据库操作】
聊天业务类 主要业务 源代码如下：
package com.vo;public class User {private String id; //scriptSessionIdprivate String name;private String sid; //sessionIdpublic String getId() {return id;}public void setId(String id) {this.id = id;}public String getName() {return name;}public void setName(String name) {this.name = name;}public User(String id, String name) {super();this.id = id;this.name = name;}public User() {super();// TODO Auto-generated constructor stub}public String getSid() {return sid;}public void setSid(String sid) {this.sid = sid;}public User(String id, String name, String sid) {super();this.id = id;this.name = name;this.sid = sid;}}
