使用Redis缓存对象会出现下图现象:
键值对都是乱码形式。
解决以上问题:
如果是xml配置的
我们直接注入官方给定的keySerializer,valueSerializer,hashKeySerializer即可:
<bean id="apiRedisTemplate" class="org.springframework.data.redis.core.RedisTemplate"
p:connection-factory-ref="apiCacheRedisConnectionFactory">
<property name="keySerializer">
<bean
class="org.springframework.data.redis.serializer.GenericJackson2JsonRedisSerializer" />
</property>
<property name="valueSerializer">
<bean
class="org.springframework.data.redis.serializer.GenericJackson2JsonRedisSerializer" />
</property>
<property name="hashKeySerializer">
<bean
class="org.springframework.data.redis.serializer.GenericJackson2JsonRedisSerializer" />
</property>
<property name="hashValueSerializer">
<bean
class="org.springframework.data.redis.serializer.GenericJackson2JsonRedisSerializer" />
</property>
<property name="stringSerializer">
<bean
class="org.springframework.data.redis.serializer.StringRedisSerializer" />
</property>
</bean>
spring boot 项目配置RedisConfig的时候使用以下方法:
@Configuration
public class RedisConfig {
@Bean("jsonRedisTemplate")
public RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory)
throws UnknownHostException {
RedisTemplate<Object, Object> template = new RedisTemplate<Object, Object>();
template.setConnectionFactory(redisConnectionFactory); //解决日期序列化问题
ObjectMapper om = new ObjectMapper();
om.setDateFormat(new SimpleDateFormat("yyyy-MM-dd hh:mm:ss"));
GenericJackson2JsonRedisSerializer genericJackson2JsonRedisSerializer = new GenericJackson2JsonRedisSerializer(om);
template.setDefaultSerializer(genericJackson2JsonRedisSerializer);
return template;
}
}
Redis存入中文,取出来是乱码wenti
默认情况下,用redis存入中文,取出时会出现乱码情况,如图:
解决
我们再启动redis时,可以在redis-cli 后面加上 --raw,如图
以上为个人经验,希望能给大家一个参考,也希望大家多多支持编程网。
