Java实现简单聊天机器人

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();
        }
    }
}
