Redis缓存-序列化对象存储乱码问题的解决

原作者: [db:作者] 来自: [db:来源] 收藏邀请

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;

    }
}
