RedisTemplate
Spring Boot中Jedis几个api返回值的确认
@RequestMapping("/del/{key}") public String del(@PathVariable("key") String key) { try { //键不存在时,也不会抛异常 redisTemplate.delete(key); return "Success"; } catch (Exception e) { return e.getMessage(); } }
RedisTemplate如果是按以下设置的话,直接对String类型使用get方法获取值时,会报以下的错。原因是存放的数据是经过Serialize的。deserialize就是会报错。网上给一个解决办法是使用get(0,-1).
但是,这种场景下,不能使用increment方法,因为存放的值是经过Serialize的,不是数字了,不能increment
这种场景可以使用StringRedisTemplate ,如上例所示
org.springframework.data.redis.serializer.SerializationException : Cannot deserialize; nested exception is org.springframework.core.serializer.support.SerializationFailedException: Failed to deserialize payload. Is the byte array a result of corresponding serialization for DefaultDeserializer?; nested exception is java.io.EOFException
RedisTemplate<String, Serializable> rt = new RedisTemplate<>(); rt.setConnectionFactory(jedisConnectionFactory()); JdkSerializationRedisSerializer jdkSerializationRedisSerializer = new JdkSerializationRedisSerializer(); rt.setKeySerializer(new StringRedisSerializer()); rt.setValueSerializer(jdkSerializationRedisSerializer);
