Redis key-value乱码如何解决

这篇“Redis key-value乱码如何解决”文章的知识点大部分人都不太理解，所以小编给大家总结了以下内容，内容详细，步骤清晰，具有一定的借鉴价值，希望大家阅读完这篇文章能有所收获，下面我们一起来看看这篇“Redis key-value乱码如何解决”文章吧。

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;@SpringBootConfigurationpublic class RedisConfig extends CachingConfigurerSupport {        @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);
