springboot调用redis数据库，操作字符串

1.maven导入SpringDataRedis

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

2.config/RedisConfiguration.class

package com.sky.config;import lombok.extern.slf4j.Slf4j;
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.GenericJackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;@Configuration
@Slf4j
public class RedisConfiguration {@Beanpublic RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {RedisTemplate<String, Object> template = new RedisTemplate<>();template.setConnectionFactory(redisConnectionFactory);// 设置序列化器template.setKeySerializer(new StringRedisSerializer());template.setValueSerializer(new GenericJackson2JsonRedisSerializer());template.setHashKeySerializer(new StringRedisSerializer());template.setHashValueSerializer(new GenericJackson2JsonRedisSerializer());return template;}
}

3.写测试类，来操作redis/:SpringDataRedisTest

package com.sky.test;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.core.*;import java.util.concurrent.TimeUnit;@SpringBootTest
public class SpringDataRedisTest {@Autowiredprivate RedisTemplate<String, Object> redisTemplate;@Testpublic void testSpringDataRedis() {// 这里可以编写测试代码，验证Spring Data Redis的功能System.out.println("RedisTemplate: " + redisTemplate);// 例如，测试RedisTemplate的基本操作// 可以使用@Autowired注入RedisTemplate并进行操作ValueOperations<String, Object> value = redisTemplate.opsForValue();ListOperations<String, Object> list = redisTemplate.opsForList();HashOperations<String, Object, Object> hash = redisTemplate.opsForHash();SetOperations<String, Object> set = redisTemplate.opsForSet();ZSetOperations<String, Object> zset = redisTemplate.opsForZSet();}@Testpublic void testRedis() {ValueOperations<String, Object> value = redisTemplate.opsForValue();// 设置code为135790，有效期1分钟，如果不存在则设置，存在则不做任何操作redisTemplate.opsForValue().setIfAbsent("code", 135790,  1, TimeUnit.MINUTES);// 设置code为135790，有效期1分钟，存在就修改，不存在就添加redisTemplate.opsForValue().set("code", 135790,  1, TimeUnit.MINUTES);value.set("city", "北京");// 获取code的值System.out.println(value.get("city"));}
}
