修改 pom.xml 加入 kafka 依赖

<dependency>
    <groupId>org.springframework.kafka</groupId>
    <artifactId>spring-kafka</artifactId>
    <version>2.3.2.RELEASE</version>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-test</artifactId>
    <scope>test</scope>
    <version>2.7.3</version>
</dependency>

添加 kafka.xml 配置文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">

    <bean id="producerProperties" class="java.util.HashMap">
        <constructor-arg>
            <map>
                <entry key="bootstrap.servers" value="localhost:9092" />
                <entry key="retries" value="3" />
                <entry key="ack" value="1" />
                <entry key="buffer.memory" value="33554432" />
                <entry key="key.serializer"
                       value="org.apache.kafka.common.serialization.StringSerializer" />
                <entry key="value.serializer"
                       value="org.apache.kafka.common.serialization.StringSerializer" />
            </map>
        </constructor-arg>
    </bean>

    <bean id="producerFactory"
          class="org.springframework.kafka.core.DefaultKafkaProducerFactory">
        <constructor-arg>
            <ref bean="producerProperties" />
        </constructor-arg>
    </bean>
    <bean id="kafkaTemplate"
          class="org.springframework.kafka.core.KafkaTemplate">
        <constructor-arg ref="producerFactory" />
        <property name="defaultTopic" value="defaultTopic" />
    </bean>
</beans>

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.kafka.core.KafkaTemplate;
import org.springframework.test.context.ContextConfiguration;

import java.util.UUID;

@RunWith(value = SpringJUnit4ClassRunner.class)
@ContextConfiguration(value = {"classpath:kafka.xml"})
@Slf4j
public class KafkaHookTest
{
    @Autowired
    private KafkaTemplate kafkaTemplate;

    @Test
    public void test()

        KafkaHook kafkaHook = injector.getInstance(KafkaHook.class);
        HookMessage hookMessage = new HookMessage();
        hookMessage.setInstance(kafkaTemplate);
        hookMessage.setUnique(UUID.randomUUID().toString());
        hookMessage.setState("SUCCESS");
        hookMessage.setTopic("kafka-report");
        kafkaHook.execute(hookMessage);
