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<StringRedisSerializer, Serializable> rt = new RedisTemplate<>();
rt.setConnectionFactory(jedisConnectionFactory());
JdkSerializationRedisSerializer jdkSerializationRedisSerializer = new JdkSerializationRedisSerializer();
rt.setKeySerializer(new StringRedisSerializer());
rt.setValueSerializer(jdkSerializationRedisSerializer);
