redis官網

微軟寫的windows下的redis

我們下載第一個

額案后基本一路默認就行了

安裝后，服務自動啟動，以后也不用自動啟動。

出現這個表示我們連接上了。

Spring整合Redis

引入依賴
- spring-boot-starter-data-redis

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

配置Redis
- 配置數據庫參數

# RedisProperties spring.redis.database=11#第11個庫，這個隨便 spring.redis.host=localhost spring.redis.port=6379#端口

- 編寫配置類，構造RedisTemplate

這個springboot已經幫我們配了，但是默認object，我想改成string

import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.data.redis.connection.RedisConnectionFactory; import org.springframework.data.redis.core.RedisTemplate; import org.springframework.data.redis.serializer.RedisSerializer;@Configuration public class RedisConfig {@Beanpublic RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory factory) {RedisTemplate<String, Object> template = new RedisTemplate<>();template.setConnectionFactory(factory);// 設置key的序列化方式template.setKeySerializer(RedisSerializer.string());// 設置value的序列化方式template.setValueSerializer(RedisSerializer.json());// 設置hash的key的序列化方式template.setHashKeySerializer(RedisSerializer.string());// 設置hash的value的序列化方式template.setHashValueSerializer(RedisSerializer.json());template.afterPropertiesSet();return template;}}

訪問Redis
- redisTemplate.opsForValue()
- redisTemplate.opsForHash()
- redisTemplate.opsForList()
- redisTemplate.opsForSet()
- redisTemplate.opsForZSet()

@RunWith(SpringRunner.class) @SpringBootTest @ContextConfiguration(classes = CommunityApplication.class) public class RedisTests {@Autowiredprivate RedisTemplate redisTemplate;@Testpublic void testStrings() {String redisKey = "test:count";redisTemplate.opsForValue().set(redisKey, 1);System.out.println(redisTemplate.opsForValue().get(redisKey));System.out.println(redisTemplate.opsForValue().increment(redisKey));System.out.println(redisTemplate.opsForValue().decrement(redisKey));}@Testpublic void testHashes() {String redisKey = "test:user";redisTemplate.opsForHash().put(redisKey, "id", 1);redisTemplate.opsForHash().put(redisKey, "username", "zhangsan");System.out.println(redisTemplate.opsForHash().get(redisKey, "id"));System.out.println(redisTemplate.opsForHash().get(redisKey, "username"));}@Testpublic void testLists() {String redisKey = "test:ids";redisTemplate.opsForList().leftPush(redisKey, 101);redisTemplate.opsForList().leftPush(redisKey, 102);redisTemplate.opsForList().leftPush(redisKey, 103);System.out.println(redisTemplate.opsForList().size(redisKey));System.out.println(redisTemplate.opsForList().index(redisKey, 0));System.out.println(redisTemplate.opsForList().range(redisKey, 0, 2));System.out.println(redisTemplate.opsForList().leftPop(redisKey));System.out.println(redisTemplate.opsForList().leftPop(redisKey));System.out.println(redisTemplate.opsForList().leftPop(redisKey));}@Testpublic void testSets() {String redisKey = "test:teachers";redisTemplate.opsForSet().add(redisKey, "劉備", "關羽", "張飛", "趙云", "諸葛亮");System.out.println(redisTemplate.opsForSet().size(redisKey));System.out.println(redisTemplate.opsForSet().pop(redisKey));System.out.println(redisTemplate.opsForSet().members(redisKey));}@Testpublic void testSortedSets() {String redisKey = "test:students";redisTemplate.opsForZSet().add(redisKey, "唐僧", 80);redisTemplate.opsForZSet().add(redisKey, "悟空", 90);redisTemplate.opsForZSet().add(redisKey, "八戒", 50);redisTemplate.opsForZSet().add(redisKey, "沙僧", 70);redisTemplate.opsForZSet().add(redisKey, "白龍馬", 60);System.out.println(redisTemplate.opsForZSet().zCard(redisKey));System.out.println(redisTemplate.opsForZSet().score(redisKey, "八戒"));System.out.println(redisTemplate.opsForZSet().reverseRank(redisKey, "八戒"));System.out.println(redisTemplate.opsForZSet().reverseRange(redisKey, 0, 2));}@Testpublic void testKeys() {redisTemplate.delete("test:user");System.out.println(redisTemplate.hasKey("test:user"));redisTemplate.expire("test:students", 10, TimeUnit.SECONDS);} }

這樣還是稍微有點麻煩，我們其實可以綁定key

// 多次訪問同一個key@Testpublic void testBoundOperations() {String redisKey = "test:count";BoundValueOperations operations = redisTemplate.boundValueOps(redisKey);operations.increment();operations.increment();operations.increment();operations.increment();operations.increment();System.out.println(operations.get());}
