Redis key-value乱码的解决

作者:JavaEE_202008

本文主要介绍了Redis key-value乱码的解决,文中通过示例代码介绍的非常详细,具有一定的参考价值,感兴趣的小伙伴们可以参考一下

redis 配置类

import com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.jackson.annotation.PropertyAccessor;
import com.fasterxml.jackson.databind.ObjectMapper;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringBootConfiguration;
import org.springframework.cache.CacheManager;
import org.springframework.cache.annotation.CachingConfigurerSupport;
import org.springframework.context.annotation.Bean;
import org.springframework.data.redis.cache.RedisCacheManager;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;

@SpringBootConfiguration
public class RedisConfig extends CachingConfigurerSupport {

    /**
     * 注入 RedisConnectionFactory
     */
    @Autowired
    private RedisConnectionFactory redisConnectionFactory;

    @Bean
    public CacheManager cacheManager(RedisConnectionFactory factory) {
        return RedisCacheManager.builder(factory).build();
    }

    @Bean
    public RedisTemplate<String, Object> functionDomainRedisTemplate() {
        RedisTemplate<String, Object> redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(redisConnectionFactory);

        // 使用Jackson2JsonRedisSerialize 替换默认序列化
        Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);

        ObjectMapper objectMapper = new ObjectMapper();
        objectMapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        objectMapper.activateDefaultTyping(objectMapper.getPolymorphicTypeValidator(), ObjectMapper.DefaultTyping.NON_FINAL);
        jackson2JsonRedisSerializer.setObjectMapper(objectMapper);

        // 设置value的序列化规则和 key的序列化规则
        StringRedisSerializer stringRedisSerializer = new StringRedisSerializer();
        redisTemplate.setKeySerializer(stringRedisSerializer);
        redisTemplate.setHashKeySerializer(stringRedisSerializer);
        redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);
        redisTemplate.setHashValueSerializer(jackson2JsonRedisSerializer);
        redisTemplate.afterPropertiesSet();
        return redisTemplate;
    }

}

当使用opsForValue() 存取String类型key,value情形

    @Autowired
    private StringRedisTemplate redisTemplate;

当使用opsForValue() 存取String类型key,自定义对象value情形

    @Autowired
    private RedisTemplate<String, Object> redisTemplate;

当使用hash结构时

    @Autowired
    private RedisTemplate<String, Object> redisTemplate;
BoundHashOperations<String, Object, Object> ops = redisTemplate.boundHashOps("key1");
        ops.put("key2",obj);
