本文实例为大家分享了Java实现简单聊天机器人的具体代码,供大家参考,具体内容如下
整个小案例:整合了Java socket编程、jdbc知识(ORM/DAO)
创建数据库和表,准备表数据(MySQL)
首先创建一个数据库android
然后创建一个表dictionary,字段:
id int
receive varchar(100)
response varchar(100)
receive 表示受到的信息
response 表示回应的信息

create database android; use android; create table dictionary( id int AUTO_INCREMENT, receive varchar (100), response varchar (100), PRIMARY KEY (id) ) DEFAULT CHARSET=utf8; insert into dictionary values ( null , '你好' , '好你妹!' ); insert into dictionary values ( null , '你叫什么' , '你想泡我啊?' ); insert into dictionary values ( null , '你叫什么' , '同志,不约' ); insert into dictionary values ( null , '打你哦' , '来啊,来打我啊' ); |
对象设置(ORM)
对象关系映射,设置对象对应数据库中的各字段。

" ; try (Connection c = getConnection(); PreparedStatement ps = c.prepareStatement(sql);) { ps.setString( 1 , recieve); ResultSet rs = ps.executeQuery(); while (rs.next()) { Dictionary d = new Dictionary(); int id = rs.getInt( 1 ); String receive = rs.getString( "receive" ); String response = rs.getString( "response" ); d.id = id; d.receive = receive; d.response = response; ds.add(d); } } catch (SQLException e) { e.printStackTrace(); } return ds; } } |
此处,如果不是代码编写问题,出现jdbc错误,请注意是否打开MySQL数据库。
server端
主要是正常的socket入门编程。
通过输入流收到Client端发来的数据(打印),然后查询语料对话库,查到返回正常对话,查不到表示听不懂。
