在这种情况下,主要问题是 @Bean("someName") 未加载到 Spring 容器中,因此在创建 bean 时,破解在 @Bean("someName") 下返回的配置,例如......
@Configuration
static class ContextConfiguration {
@Bean
@Qualifier("InternalKafkaProducer")
public KafkaTemplate<Object, Object> publishingTemplate(){
return new KafkaTemplate(new DefaultKafkaProducerFactory<>(getKafkaTemplate()));
}
}
@Autowired
private KafkaTemplate<Object, Object> kafkaTemplate;
@Test
public void test(){
//some code
}
private static HashMap<String, Object> getKafkaTemplate() {
//return the properties;
}
}//test class end
Main class
@Autowired
@Qualifier("someName")
private KafkaTemplate<Object, Object>
in configuration class
@Bean(name = "InternalKafkaProducer")
public KafkaTemplate<Object, Object> getKafkaTemplate() {
final Map<String, Object> properties = new HashMap<String, Object>();
properties.put(ProducerConfig.BOOTSTRAP_SERVERS_CONFIG, bootStrapServer);
properties.put("security.protocol", securityProtocol);
properties.put("sasl.mechanism", saslMechanism);
properties.put("sasl.jaas.config", saslJaasConfig);
properties.put("sasl.login.callback.handler.class", saslOauthCallbackClass);
properties.put(ProducerConfig.KEY_SERIALIZER_CLASS_CONFIG, StringSerializer.class);
properties.put(ProducerConfig.VALUE_SERIALIZER_CLASS_CONFIG, StringSerializer.class);
final KafkaTemplate<Object, Object> template = new KafkaTemplate<Object, Object>(new DefaultKafkaProducerFactory<>(properties));
template.setProducerListener(new KafkaProducerListener("InternalKafkaProducer", template));
return template;
}
