Redis key-value乱码的解决

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.annota编程客栈tion.Autowired;
import org.springframework.boot.SpringBootConfiguration;
import org.springframework.cache.CacheManager;
import org.springframework.cache.annotation.CachingConfigurerSupport;
pGgZJPimport org.springframework.context.annotation.Bean;
import org.springframework.data.redis.cache.RedisCacheManager;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.pGgZJPdata.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer;
import org.sprinhttp://www.devze.comgframework.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.setObjectpGgZJPMapper(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 Redi开发者_NewSQLsTemplate<String, Object> redisTemplate;

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