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。
package socket;public class Dictionary { public int id; public String receive; // 接收 public String response; // 回应}数据访问对象（DAO）
package socket;import java.sql.Connection;import java.sql.DriverManager;import java.sql.PreparedStatement;import java.sql.ResultSet;import java.sql.SQLException;import java.util.ArrayList;import java.util.List;public class DictionaryDAO { public DictionaryDAO() { try { Class.forName("com.mysql.jdbc.Driver"); } catch (ClassNotFoundException e) { e.printStackTrace(); } } public Connection getConnection() throws SQLException { return DriverManager.getConnection("jdbc:mysql://127.0.0.1:3306/android?characterEncoding=UTF-8", "root", "admin"); } public List<Dictionary> query(String recieve) { List<Dictionary> ds = new ArrayList<Dictionary>(); String sql = "select * from dictionary where receive = ? "; 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。
package socket;import java.io.DataInputStream;import java.io.DataOutputStream;import java.io.IOException;import java.io.InputStream;import java.io.OutputStream;import java.net.ServerSocket;import java.net.Socket;import java.util.ArrayList;import java.util.Collections;import java.util.List;public class Server { private static List<String> cannotUnderstand= new ArrayList<>(); static{ cannotUnderstand.add("听求不懂啊"); cannotUnderstand.add("说人话"); cannotUnderstand.add("再说一遍？"); cannotUnderstand.add("大声点"); cannotUnderstand.add("老子在忙，一边玩儿去"); } public static void main(String[] args) { try { ServerSocket ss = new ServerSocket(8888); System.out.println("监听在端口号:8888"); Socket s = ss.accept(); InputStream is = s.getInputStream(); DataInputStream dis = new DataInputStream(is); OutputStream os = s.getOutputStream(); DataOutputStream dos = new DataOutputStream(os); while (true) { String msg = dis.readUTF(); System.out.println(msg); List<Dictionary> ds= new DictionaryDAO().query(msg); String response = null; if(ds.isEmpty()){ Collections.shuffle(cannotUnderstand); response = cannotUnderstand.get(0); } else{ Collections.shuffle(ds); response = ds.get(0).response; } dos.writeUTF(response); } } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } }}Client端
正常的收发信息
package socket;import java.io.DataInputStream;import java.io.DataOutputStream;import java.io.IOException;import java.io.InputStream;import java.io.OutputStream;import java.net.Socket;import java.net.UnknownHostException;import java.util.Scanner;public class Client { public static void main(String[] args) { try { // 连接到本机的8888端口 Socket s = new Socket("127.0.0.1", 8888); // OutputStream os = s.getOutputStream(); DataOutputStream dos = new DataOutputStream(os); InputStream is = s.getInputStream(); DataInputStream dis = new DataInputStream(is); while (true) { Scanner sc = new Scanner(System.in); String str = sc.next(); dos.writeUTF(str); String msg = dis.readUTF(); System.out.println(msg); } } catch (UnknownHostException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } }}以上是“Java怎么实现简单聊天机器人”这篇文章的所有内容，感谢各位的阅读！相信大家都有了一定的了解，希望分享的内容对大家有所帮助，如果还想学习更多知识，欢迎关注编程网行业资讯频道！
