在redisConfig配置类注入bean

@Configuration
public class RedisConfig {@Beanpublic RedisTemplate<String,Object> redisTemplate(RedisConnectionFactory factory){RedisTemplate<String, Object> template = new RedisTemplate<String, Object>();template.setConnectionFactory(factory);//Json序列化配置Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);ObjectMapper om = new ObjectMapper();om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);jackson2JsonRedisSerializer.setObjectMapper(om);//String序列号配置StringRedisSerializer stringRedisSerializer = new StringRedisSerializer();//key和hash的key都采用String的序列化配置template.setKeySerializer(stringRedisSerializer);template.setHashKeySerializer(stringRedisSerializer);//value和hash的value采用Json的序列化配置template.setValueSerializer(jackson2JsonRedisSerializer);template.setHashValueSerializer(jackson2JsonRedisSerializer);template.afterPropertiesSet();return template;}
}

 

 注入Redisson

 使用非常简单：

 代码写到这里，看下是不是还有问题，是不是解决了超卖现象，在高并发情况下其实这里依然会有问题，偶尔会出现异常

 所以代码在加判断更严谨一下
