8.Java+Redis

Jedis

参考博文-- 要注意的是修改完之后必须重启 linux 虚拟机

 

加入依赖

        <dependency>
            <groupId>redis.clients</groupId>
            <artifactId>jedis</artifactId>
            <version>3.2.0</version>
        </dependency>
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>fastjson</artifactId>
            <version>1.2.62</version>
        </dependency>

测试

public class TestPing {
    public static void main(String[] args) {
        Jedis jedis=new Jedis("192.168.116.128",6379);
        System.out.println(jedis.ping());

}



}

命令基本就是 redis 的命令 

 事务操作

public class TestTask {
    public static void main(String[] args) {
        Jedis jedis=new Jedis("192.168.116.128",6379);
        JSONObject object = new JSONObject();
        object.put("hello","word");
        object.put("name","xiaowu");
        //开启事务
        Transaction muti=jedis.multi();
        String result=object.toJSONString();
        try {
            muti.set("user1",result);
            muti.exec();//执行事务
        }catch (Exception e){muti.discard();//放弃事务
            e.printStackTrace();}finally {
            System.out.println(jedis.get("user1"));
            jedis.close();//关闭连接
        }
    }
}

 SpringBoot 整合

选择的项目

 

jedis：采用的直连，多个线程操作是不安全的，如果想要避免，使用 jedis pool 连接池

lettuce：采用 netty，实例可以在多个线程中进行共享，不存在线程不安全的情况

配置文件

spring.redis.host= 192.168.116.128
spring.redis.port=6379

测试

@SpringBootTest
class SpringbootRedisApplicationTests {

@Autowired
</span><span style="color: rgba(0, 0, 255, 1)">private</span><span style="color: rgba(0, 0, 0, 1)"> RedisTemplate redisTemplate;

    redisTemplate.opsForValue().set("xiaowu","123"<span style="color: rgba(0, 0, 0, 1)">);
    System.out.println(redisTemplate.opsForValue().get(</span>"xiaowu"<span style="color: rgba(0, 0, 0, 1)">));
    </span><span style="color: rgba(0, 128, 0, 1)">//</span><span style="color: rgba(0, 128, 0, 1)">这个对象是用来操作数据库的</span>
    RedisConnection connection=<span style="color: rgba(0, 0, 0, 1)">redisTemplate.getConnectionFactory().getConnection();
    connection.flushDb();
}



}

 可以看到我们放到数据库的东西，用数据库查询出来被序列化了，这里默认使用的是 jdk 序列化

 

 自定义 RedisTemplate 类

这是一个固定的模板，在企业中拿去可以直接使用

 

 

 

 

 在测试的时候为了防止因为重名导致的歧义

 

 自定义工具类
