1.引入依赖

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-redis</artifactId>
        </dependency>

2.配置Redis数据源 

 

 

  redis:
    host: ${sky.redis.host}
    port: ${sky.redis.port}
    password: ${sky.redis.password}
    database: ${sky.redis.database}

 

  redis:
    host: localhost
    port: 6379
    password: 123456
    database: 0

3.编写配置 （Configuration）类RedisTemplate对象

@Configuration
@Slf4j
public class RedisConfiguration {

    @Bean
    public RedisTemplate redisTemplate(RedisConnectionFactory redisConnectionFactory){
        log.info("开始创建redis模板类...");
        RedisTemplate redisTemplate = new RedisTemplate();
        // 设置Key的序列化器，默认为JdkSerializationRedisSerializer
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        redisTemplate.setConnectionFactory(redisConnectionFactory);
        return redisTemplate;
    }

}

 4.通过redisTemplate对象操作Redis

package com.sky;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.data.redis.connection.DataType;

import java.util.Set;
import java.util.concurrent.TimeUnit;

@SpringBootTest
public class SpringDataRedisTest {
    @Autowired
    private RedisTemplate redisTemplate;

    @Test
    public void testRedisTemplate(){
        System.out.println(redisTemplate);
        HashOperations hashOperations = redisTemplate.opsForHash();
        ListOperations listOperations = redisTemplate.opsForList();
        SetOperations setOperations = redisTemplate.opsForSet();
        ZSetOperations zSetOperations = redisTemplate.opsForZSet();
    }

*//*
    * 操作字符串类型
    * *//*
    @Test
    public void testRedis(){
        ValueOperations valueOperations = redisTemplate.opsForValue();
        redisTemplate.opsForValue().set("name","小明");
        String name = (String) redisTemplate.opsForValue().get("name");
        System.out.println(name);
        redisTemplate.opsForValue().set("code","1234",3, TimeUnit.MINUTES);//code验证码
        redisTemplate.opsForValue().setIfAbsent("lock","1");
        redisTemplate.opsForValue().setIfAbsent("lock","2");
    }

 *//*
    * 操作哈希类型的数据
    * *//*
    @Test
    public void testHash(){
        //hset hdel hkeys hvals
        HashOperations hashOperations = redisTemplate.opsForHash();
        hashOperations.put("100","name","Tom");
        hashOperations.put("100","age","20");

        String name = (String) hashOperations.get("100","name");
        System.out.println(name);

        Set keys = hashOperations.keys("100");
        System.out.println(keys);

        List values = hashOperations.values("100");
        System.out.println(values);

        hashOperations.delete("100","age");
    }

*//*
    * 通用命令操作
    * *//*
    @Test
    public void testcommon(){
        //keys exits type del
        Set keys = redisTemplate.keys("*");
        System.out.println(keys);

        Boolean name = redisTemplate.hasKey("name");
        Boolean set1 = redisTemplate.hasKey("set1");

        for (Object key : keys) {
            DataType type = redisTemplate.type(key);
            System.out.println(type);
        }
        redisTemplate.delete("mylist");
    }

*//*
    * 操作列表类型的数据
    * *//*
    @Test
    public  void testList(){
        //lpush lrange rpop llen l--list
        ListOperations listOperations =redisTemplate.opsForList();

        listOperations.leftPushAll("mylist","a","b","c");
        listOperations.leftPush("mylist","d");

        List mylist = listOperations.range("mylist", 0, -1);
        System.out.println(mylist);

        listOperations.rightPop("mylist");

        Long size = listOperations.size("mylist");
        System.out.println(size);
    }


*//*    * 操作有序集合类型的数据
    * *//*
    @Test
    public void testZset(){
        //zadd zrange zincrby zrem
        ZSetOperations zSetOperations =redisTemplate.opsForZSet();

        zSetOperations.add("zset1","a",10);
        zSetOperations.add("zset1","b",12);
        zSetOperations.add("zset1","c",9);

        Set zset1 = zSetOperations.range("zset1", 0, -1);
        System.out.println(zset1);

        zSetOperations.incrementScore("zset1","c",10);

        zSetOperations.remove("zset1","a","b");
    }


  *//*  * 操作集合类型的数据
    * *//*
    @Test
    public  void  testSet(){
        //sadd smember scard sinter sunion srem
        SetOperations setOperations = redisTemplate.opsForSet();

}
