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.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.data.redis.connection.DataType;
import org.springframework.data.redis.core.*;
import java.util.List;
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();
setOperations.add("set1","a","b","c","d");
setOperations.add("set1","a","b","x","y");
Set members = setOperations.members("set1");
System.out.println(members);
Long size = setOperations.size("set1");
System.out.println(size);
Set intersect = setOperations.intersect("set1", "set2");
System.out.println(intersect);
Set union = setOperations.union("set1","set2");
System.out.println(union);
setOperations.remove("set1","a","b");
}
}
