本文實例為大家分享了Java實現(xiàn)簡單聊天機器人的具體代碼，供大家參考，具體內(nèi)容如下

整個小案例：整合了Java socket編程、jdbc知識（ORM/DAO）

創(chuàng)建數(shù)據(jù)庫和表，準備表數(shù)據(jù)（MySQL）

首先創(chuàng)建一個數(shù)據(jù)庫android然后創(chuàng)建一個表dictionary，字段：

id intreceive varchar(100)response varchar(100)

receive 表示受到的信息response 表示回應的信息

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，不約’);insert into dictionary values(null,’打你哦’,’來啊，來打我啊’);

對象設置（ORM）

對象關系映射，設置對象對應數(shù)據(jù)庫中的各字段。

package socket;public class Dictionary { public int id; public String receive; // 接收 public String response; // 回應}

數(shù)據(jù)訪問對象（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; }}

此處，如果不是代碼編寫問題，出現(xiàn)jdbc錯誤，請注意是否打開MySQL數(shù)據(jù)庫。

server端

主要是正常的socket入門編程。通過輸入流收到Client端發(fā)來的數(shù)據(jù)（打印），然后查詢語料對話庫，查到返回正常對話，查不到表示聽不懂。

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('聽求不懂啊');cannotUnderstand.add('說人話');cannotUnderstand.add('再說一遍？');cannotUnderstand.add('大聲點');cannotUnderstand.add('老子在忙，一邊玩兒去'); } public static void main(String[] args) {try { ServerSocket ss = new ServerSocket(8888); System.out.println('監(jiān)聽在端口號: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

正常的收發(fā)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 { // 連接到本機的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();} }}
