使用socket封装一个java可执行redis命令的工具类

以下是一个简单的Java工具类，用于连接到Redis服务器并执行命令：

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.Socket;

public class RedisClient {
    private String host;
    private int port;
    private Socket socket;
    private BufferedReader input;
    private PrintWriter output;

    public RedisClient(String host, int port) {
        this.host = host;
        this.port = port;
    }

    public void connect() throws Exception {
        socket = new Socket(host, port);
        input = new BufferedReader(new InputStreamReader(socket.getInputStream()));
        output = new PrintWriter(socket.getOutputStream(), true);
    }

    public void sendCommand(String command) throws Exception {
        output.println(command);
        String response = input.readLine();
        System.out.println(response);
    }

    public void disconnect() throws Exception {
        input.close();
        output.close();
        socket.close();
    }
}

使用该工具类可以执行Redis命令，例如：

public static void main(String[] args) {
    try {
        RedisClient client = new RedisClient("localhost", 6379);
        client.connect();
        client.sendCommand("SET mykey somevalue");
        client.sendCommand("GET mykey");
        client.disconnect();
    } catch (Exception e) {
        e.printStackTrace();
    }
}

这个例子展示了如何连接到本地Redis服务器，设置一个键值对，并获取该键的值。你可以根据需要修改或扩展该工具类来执行其他Redis命令。
