kafka可以生产无法消费的问题

问题遇到的现象和发生背景

我用java代码,已经实现了生产消息到kafka,用桌面工具查询是添加上的,kafka也在我本地创建的,但是消费时候poll的数据条数始终为0

问题相关代码
import org.apache.kafka.clients.consumer.ConsumerRecord;
import org.apache.kafka.clients.consumer.ConsumerRecords;
import org.apache.kafka.clients.consumer.KafkaConsumer;
import org.apache.kafka.common.serialization.StringDeserializer;

import java.time.Duration;

我的解答思路和尝试过的方法

我把ip乱改成一个不存在的地址,但是发现这个consumer对象依然可以创建,消费时候也不报错,但是去查询时候发现依然没有被消费,poll的时候依然poll的是0条数据,改server.properties也无效。

listeners=PLAINTEXT://10.8.13.159:9092
#   EXAMPLE:
#     listeners = PLAINTEXT://your.host.name:9092
#listeners=PLAINTEXT://:9092

# Listener name, hostname and port the broker will advertise to clients.
# If not set, it uses the value for "listeners".
advertised.listeners=PLAINTEXT://10.8.13.159:9092
我想要达到的结果

能够正常消费kafka数据
