springboot实现redis序列化

如果我们使用redis可视化工具查看k/v时，都是乱码形式，
所以需要使用Jackson进行JSON格式的序列化和反序列才能看到具体数值。

@EnableRedisHttpSession是把session整合到redis中，需要引入以下的maven包

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

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.RedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;
import org.springframework.session.data.redis.config.annotation.web.http.EnableRedisHttpSession;

/**
 * redis配置类，序列化
 */
@Configuration
@EnableRedisHttpSession
public class RedisConfig {

    /**
     * redisTemplate 序列化配置
     * @param factory
     * @return
     */
    @Bean
    public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory factory) {
        RedisTemplate<String, Object> template = new RedisTemplate<>();
        // key 序列化
        template.setKeySerializer(new StringRedisSerializer());
        // value 序列化
        template.setValueSerializer(new GenericJackson2JsonRedisSerializer());
        // hash key 序列化
        template.setHashKeySerializer(new StringRedisSerializer());
        // hash value 序列化
        template.setHashValueSerializer(new GenericJackson2JsonRedisSerializer());
        // 注入连接工厂
        template.setConnectionFactory(factory);
        return template;
    }

    /**
     * 设置spring session redis 序列化方式
     * @return
     */
    @Bean
    public RedisSerializer<Object> springSessionDefaultRedisSerializer() {
        return new GenericJackson2JsonRedisSerializer();
    }

}
