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:

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。
