这家伙太懒，什么都没留下
这家伙太懒，什么都没留下
zookeep 用的是单机的 kafka配置我也是配的单机的
代码放在项目里面 项目和kafka,zookeep 都是放在服务器上的
application.yml中配置：
spring
kafka:
bootstrap-servers: localhost:9092
kafka server.properties中没有更改或增加任何配置
代码中：
private void send(String topic, String key, String data) {
kafkaTemplate.send(topic, key, data);
}
单纯用了send方法，自己自定义了主题。
运行项目：现在经常报：
异常一：

项目偶尔可以正常使用，但是后台日志经常会报这种错误
