如何通过Spring Rest端点使用kafka中的事件

<dependency>
    <groupId>org.springframework.kafka</groupId>
    <artifactId>spring-kafka</artifactId>
</dependency>

spring.kafka.bootstrap-servers=Kafka服务器地址
spring.kafka.consumer.group-id=消费者组ID
spring.kafka.consumer.auto-offset-reset=latest

import org.springframework.kafka.core.KafkaTemplate;
import org.springframework.stereotype.Component;

@Component
public class KafkaProducer {

    private final KafkaTemplate<String, String> kafkaTemplate;

    public KafkaProducer(KafkaTemplate<String, String> kafkaTemplate) {
        this.kafkaTemplate = kafkaTemplate;
    }

    public void sendMessage(String message) {
        kafkaTemplate.send("topic名称", message);
    }
}

import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class KafkaController {

    private final KafkaProducer kafkaProducer;

    public KafkaController(KafkaProducer kafkaProducer) {
        this.kafkaProducer = kafkaProducer;
    }

    @PostMapping("/kafka/event")
    public void sendEvent(@RequestBody String event) {
        kafkaProducer.sendMessage(event);
    }
}
