导入对应版本的依赖

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

修改配置文件中的信息

spring:redis:host: 127.0.0.1port: 8888

注意: 我这里 xshell 中将 redis 的端口映射到了本机的 8888 端口, 你们映射了啥, 这里的 port 就写啥

写代码

SpringBoot 是通过 redisTemplate 对象 对 Redis 进行操作
redisTemplate 对 Redis 中的每个类型进行了封装, 使用对应类型的对应方法要先选择操作类型

---

String 类型

@Autowired
privateStringRedisTemplate redisTemplate;@RequestMapping("/testString")
public void testString() {redisTemplate.opsForValue(). set("key1", "value1");redisTemplate.opsForValue(). set("key2", "value2");redisTemplate.opsForValue(). set("key3", "value3");System.out.println(redisTemplate.opsForValue().get("key1"));System.out.println(redisTemplate.opsForValue().get("key2"));System.out.println(redisTemplate.opsForValue().get("key3"));
}

---

List 类型

@Autowired
private StringRedisTemplate redisTemplate;@RequestMapping("/testList")
public void testList() {//删库操作redisTemplate.execute((RedisConnection connection) -> {// execute 要求我们的回调方法中, 必须返回一个内容// 该回调返回的对象, 就是 execute 返回的内容connection.flushAll();return null;});redisTemplate.opsForList().leftPush("key", "val");redisTemplate.opsForList().leftPush("key", "val2");redisTemplate.opsForList().leftPush("key", "val3");System.out.println(redisTemplate.opsForList().rightPop("key"));System.out.println(redisTemplate.opsForList().rightPop("key"));System.out.println(redisTemplate.opsForList().rightPop("key"));
}

---

Set 类型

@Autowired
private StringRedisTemplate redisTemplate;@RequestMapping("testSet")
public void testSet() {redisTemplate.execute((RedisConnection connection) -> {connection.flushAll();return null;});redisTemplate.opsForSet().add("key", "111", "222","333");System.out.println(redisTemplate.opsForSet().members("key"));System.out.println(redisTemplate.opsForSet().isMember("key", "111"));System.out.println(redisTemplate.opsForSet().isMember("key", "444"));System.out.println(redisTemplate.opsForSet().size("key"));redisTemplate.opsForSet().remove("key", "111","222");System.out.println(redisTemplate.opsForSet().members("key"));
}

---

Hash 类型

@Autowired
private StringRedisTemplate redisTemplate;@RequestMapping("/testHash")
public void testHash() {redisTemplate.execute((RedisConnection connection) -> {connection.flushAll();return null;});redisTemplate.opsForHash().put("key", "f1", "111");redisTemplate.opsForHash().put("key", "f2", "222");redisTemplate.opsForHash().put("key", "f3", "333");System.out.println((String) redisTemplate.opsForHash().get("key", "f1"));System.out.println((String) redisTemplate.opsForHash().get("key", "f2"));System.out.println((String) redisTemplate.opsForHash().get("key", "f3"));System.out.println(redisTemplate.opsForHash().hasKey("key", "f1"));redisTemplate.opsForHash().delete("key", "f1");redisTemplate.opsForHash().delete("key", "f2");System.out.println(redisTemplate.opsForHash().size("key"));
}

---

ZSet 类型

@Autowired
private StringRedisTemplate redisTemplate;@RequestMapping("/testZSet")
public void testZSet() {redisTemplate.execute((RedisConnection connection) -> {connection.flushAll();return null;});redisTemplate.opsForZSet().add("key", "zhangsan", 10);redisTemplate.opsForZSet().add("key", "lisi", 20);redisTemplate.opsForZSet().add("key", "wangwu", 30);Set<String> members = redisTemplate.opsForZSet().range("key", 0, -1);System.out.println(members);Set<ZSetOperations.TypedTuple<String>> membersWithScore =redisTemplate.opsForZSet().rangeWithScores("key", 0, -1);System.out.println(membersWithScore);System.out.println(redisTemplate.opsForZSet().score("key", "zhangsan"));redisTemplate.opsForZSet().remove("key", "zhangsan");System.out.println(redisTemplate.opsForZSet().size("key"));System.out.println(redisTemplate.opsForZSet().rank("key", "lisi"));
}
