springboot中更改RedisTemplate序列化方式

RedisTemplate默认的序列化方式为jdkSerializeable，会把对象序列化存储到Redis中（二进制形式），StringRedisTemplate的默认序列化方式为StringRedisSerializer。

通过配置，将RedisTemplate的序列化方式进行更改

 1 import org.springframework.context.annotation.Bean;
 2 import org.springframework.context.annotation.Configuration;
 3 import org.springframework.data.redis.connection.RedisConnectionFactory;
 4 import org.springframework.data.redis.core.RedisTemplate;
 5 import org.springframework.data.redis.serializer.GenericJackson2JsonRedisSerializer;
 6 import org.springframework.data.redis.serializer.StringRedisSerializer;

11  * @Description:

14  */
15 @Configuration
16 public class RedisConfig {
17 
18     @Bean//参数--一个工厂
19     public RedisTemplate redisTemplate(RedisConnectionFactory redisConnectionFactory){
20         RedisTemplate redisTemplate = new RedisTemplate();
21         //给redis模板先设置连接工厂，在设置序列化规则
22         redisTemplate.setConnectionFactory(redisConnectionFactory);
23         //设置序列化规则
24         redisTemplate.setKeySerializer(new StringRedisSerializer());
25         redisTemplate.setValueSerializer(genericJackson2JsonRedisSerializer());
26         redisTemplate.setHashKeySerializer(genericJackson2JsonRedisSerializer());
27         redisTemplate.setHashValueSerializer(genericJackson2JsonRedisSerializer());
28         return redisTemplate;
29     }
30 
31     @Bean
32     public GenericJackson2JsonRedisSerializer genericJackson2JsonRedisSerializer(){
33         return new GenericJackson2JsonRedisSerializer();
34     }
35 }

这样在其他代码中

@Autowired
private RedisTemplate redisTemplate;

就可以自动装配（注入）使用了。
