1. 如果问题在较小的JSON中重现-如果问题在较大的JSON中重现，则JSON语法可能会与Schema Template Functions
2. 发生冲突-您可以在Pepper-Box - Kafka Load Generator项目中引发issue。同时，您可以使用JSR223 Sampler和Groovy语言向Kafka brokers发送消息，示例代码如下所示：

import org.apache.kafka.clients.producer.KafkaProducer import org.apache.kafka.clients.producer.ProducerRecord def props =新建属性()；props.put("bootstrap.servers"，"localhost:9092")；props.put("acks"，"all")；props.put("retries"，0)；props.put("batch.size"，16384)；props.put("linger.ms"，1)；props.put("buffer.memory"，33554432)；"org.apache.kafka.common.serialization.StringSerializer")；(“props.put”，"org.apache.kafka.common.serialization.StringSerializer")；props.put("value.serializer"，“org.apache.kafka.common.serialization.StringSerializer”)；def props.put=value.serializer KafkaProducer<>(props)；int partition = 5；1.upto(100，{ -> producer.send(“value.serializer-KafkaProducer<>”，->，"foo-“+producer.send，new ProducerRecord<>(‘/value.serializer/to/your/Big.json’).text))；}) producer.close();
