> `手动抛出异常`是指什么？
抛出异常, 终止事务, 让producer开启的事务不能正常提交.
```java
Properties kafkaProperties = new Properties();
kafkaProperties.put("acks", "all");
kafkaProperties.put("retries", 3);
kafkaProperties.put("batch.size", 3000);
kafkaProperties.put("linger.ms", 10);
kafkaProperties.put("buffer.memory", 33554432);
kafkaProperties.put("bootstrap.servers", "10.14xxx.9:9092");
kafkaProperties.put("key.serializer",
"org.apache.kafka.common.serialization.StringSerializer");
kafkaProperties.put("value.serializer",
"org.apache.kafka.common.serialization.StringSerializer");
kafkaProperties.put("transactional.id", "send_20200522" +
increment.getAndIncrement());
kafkaProperties.put("enable.idempotence", true);
KafkaProducer<String, Object> producer = new
KafkaProducer<>(kafkaProperties);
try {
producer.initTransactions();
producer.beginTransaction();
String data = getData();
ProducerRecord<String, Object> record = new
ProducerRecord<>(topic, data);
Future<RecordMetadata> future = producer.send(record);
producer.flush();
future.get();
int a = 1/0;
producer.commitTransaction();
} catch (Exception e) {
producer.abortTransaction();
e.printStackTrace();
} finally {
producer.close();
}
```
这个是测试发送的客户端, 在 int a = 1/0 处抛出异常, 终止事务
