1.准备操作

1.1 新建工程

1.2 sca-jedis工程依赖

        </dependency>

        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>

            <scope>test</scope>
        </dependency>

            <artifactId>gson</artifactId>
            <version>2.8.6</version>
        </dependency>
    </dependencies>

1.3 sca-tempalte工程依赖

        <dependencies>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-dependencies</artifactId>

        </dependency>
    </dependencies>

1.4 测试是否可以连接Redis

package com.jt;

import org.junit.Test;
import redis.clients.jedis.Jedis;

public class JedisTests {
    @Test
    public void testGetConnection(){
        //假如不能连通,要注释掉redis.conf中 bind 127.0.0.1,
        //并将protected-mode的值修改为no,然后重启redis再试
        Jedis jedis=new Jedis("192.168.126.129",6379);
        //jedis.auth("123456");//假如在redis.conf中设置了密码
        String ping = jedis.ping();
        System.out.println(ping);
    }
}

测试结果

注意保持一致：

1.5 修改redis.conf文件

• /usr/local/docker/redis01/conf/目录下
  
  修改配置文件之后需要重启，然后再测试连接

拓展:设定编译版本

2. 基于Jedis实现对redis中字符串的操作

    @Test
    public void testString01(){
        //1.创建连接对象
        Jedis jedis=new Jedis(ip,port);
        //2.执行redis读写操作
        //2.1想redis中存储字符串数据
        jedis.set("id", "100");
        jedis.expire("id", 2);
        jedis.set("token", UUID.randomUUID().toString());
        jedis.incr("id");
        Map<String,Object> map=new HashMap<>();
        map.put("code", "201");
        map.put("name", "redis");
        Gson gson=new Gson();
        String jsonStr = gson.toJson(map);//将map对象转换为json字符串
        jedis.set("lession",jsonStr);
        //2.2删除数据
        jedis.del("id");
        //2.3获取数据
        String id=jedis.get("id");
        jsonStr=jedis.get("lession");
        System.out.println(id);
        System.out.println(jsonStr);
        //3.释放资源
        jedis.close();
    }
