Spring Boot集成Redis

要在Spring Boot中集成Redis，你需要做以下几步：

1. 添加Spring Data Redis和Jedis依赖到你的pom.xml文件中。

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

2. 在application.properties或application.yml中配置Redis连接。

# application.properties
spring.redis.host=localhost
spring.redis.port=6379

3. 使用Spring Data Redis提供的RedisTemplate或StringRedisTemplate来操作Redis。

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.stereotype.Component;
 
@Component
public class RedisService {
 
    @Autowired
    private RedisTemplate<String, Object> redisTemplate;
 
    public void setKeyValue(String key, Object value) {
        redisTemplate.opsForValue().set(key, value);
    }
 
    public Object getValueByKey(String key) {
        return redisTemplate.opsForValue().get(key);
    }
}

4. 在Spring Boot应用的主类或配置类中添加配置。

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.jedis.JedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer;
import com.fasterxml.jackson.databind.ObjectMapper;
 
@Configuration
public class RedisConfig {
 
    @Bean
    JedisConnectionFactory jedisConnectionFactory() {
        return new JedisConnectionFactory();
    }
 
    @Bean
    public RedisTemplate<String, Object> redisTemplate() {
        RedisTemplate<String, Object> template = new RedisTemplate<>();
        template.setConnectionFactory(jedisConnectionFactory());
 
        Jackson2JsonRedisSerializer<Object> jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer<>(Object.class);
        ObjectMapper om = new ObjectMapper();
        om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
        jackson2JsonRedisSerializer.setObjectMapper(om);
 
        template.setDefaultSerializer(jackson2JsonRedisSerializer);
 
        return template;
    }
}

以上代码展示了如何在Spring Boot中配置和使用Redis。你可以通过RedisService类来操作Redis，
