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。
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();
}
}
