redis中配置序列化与反序列话bean配置

因为redis在存储数据时，是将value的值进行序列化后存储，后续需要取出数据时，再反序列化为对应的对象内容输出；因为springBoot配置的自动装配机制，虽然有配置了redis的star，但是因为反序列化的方式有很多种，所以这边单独将redis的序列化方式单独进行了配置；

        我们将RedisTemplateConfig单独进行配置：

package com.cmj.config;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.connection.jedis.JedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;

import com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.jackson.annotation.PropertyAccessor;
import com.fasterxml.jackson.databind.ObjectMapper;

import redis.clients.jedis.JedisPoolConfig;
 
@Configuration
public class RedisTemplateConfig {
 
	private Logger logger = LoggerFactory.getLogger(RedisTemplateConfig.class);
	
	@Bean
	@ConfigurationProperties(prefix="spring.redis")
	public JedisPoolConfig getRedisConfig(){
		JedisPoolConfig config = new JedisPoolConfig();
		return config;
	}
	
	@Bean
	@ConfigurationProperties(prefix="spring.redis")
	public JedisConnectionFactory getConnectionFactory(){
		JedisConnectionFactory factory = new JedisConnectionFactory();
		JedisPoolConfig config = getRedisConfig();
		factory.setPoolConfig(config);
		logger.info("JedisConnectionFactory bean init success");
		return factory;
	}
 
	@Bean
	public RedisTemplate redisTemplate(RedisConnectionFactory connectionFactory) {
		RedisTemplate<Object, Object> template = new RedisTemplate<>();
		template.setConnectionFactory(connectionFactory);
 
		// 使用Jackson2JsonRedisSerializer来序列化和反序列化redis的value值（默认使用JDK的序列化方式）
		Jackson2JsonRedisSerializer serializer = new Jackson2JsonRedisSerializer(Object.class);
 
		ObjectMapper mapper = new ObjectMapper();
		mapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
		mapper.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
		serializer.setObjectMapper(mapper);
 
		template.setValueSerializer(serializer);
		// 使用StringRedisSerializer来序列化和反序列化redis的key值
		template.setKeySerializer(new StringRedisSerializer());
		template.afterPropertiesSet();
		return template;
	}
}

配置完成后，后续就可以直接对redis里面数据进行操作
