Redis key-value乱码的解决

收藏

来到golang学习网的大家，相信都是编程学习爱好者，希望在这里学习数据库相关编程知识。下面本篇文章就来带大家聊聊《Redis key-value乱码的解决》，介绍一下乱码、Rediskey-value，希望对大家的知识积累有所帮助，助力实战开发！

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
   
     functionDomainRedisTemplate() {
        RedisTemplate
    
      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
   
     redisTemplate;
   

当使用hash结构时

    @Autowired
    private RedisTemplate
   
     redisTemplate;

   

BoundHashOperations
   
     ops = redisTemplate.boundHashOps("key1");
        ops.put("key2",obj);
