Spring-Kafka:反序列化 kafka 消息时出现问题 - 类不在“受信任的包"中? [英] Spring-Kafka : Issue while deserialising kafka message - class not in a "trusted package"?
本文介绍了Spring-Kafka:反序列化 kafka 消息时出现问题 - 类不在“受信任的包"中?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我收到以下异常,因为我从一个项目中生产,而消费者从另一个项目中消费.我怎样才能解决这个问题.显然,这些包是不一样的.那么我如何确保有正确的 json 序列化.
I get the below exception because I produce from one project and the consumer consumes from another project. How can I fix this. Obviously the packages are not the same. So how can I ensure that there is proper json serialization.
The class 'com.lte.assessment.assessments.AssessmentAttemptRequest' is not in the trusted packages: [java.util, java.lang, com.lte.assessmentanalytics.model
消费者配置
@EnableKafka
@Configuration
public class KafkaConfig {
static Map<String, Object> config = new HashMap();
static {
config.put(ConsumerConfig.BOOTSTRAP_SERVERS_CONFIG, "127.0.0.1:9092");
config.put(ConsumerConfig.GROUP_ID_CONFIG, "group_id");
config.put(ConsumerConfig.KEY_DESERIALIZER_CLASS_CONFIG, StringDeserializer.class);
config.put(ConsumerConfig.VALUE_DESERIALIZER_CLASS_CONFIG, JsonDeserializer.class);
}
@Bean
public ConsumerFactory<String, AssessmentAttemptRequest> assessmentAttemptDetailsEntityConsumerFactory() {
JsonDeserializer<AssessmentAttemptRequest> deserializer = new JsonDeserializer<>();
deserializer.addTrustedPackages("com.lte.assessment.assessments");
return new DefaultKafkaConsumerFactory(config, new StringDeserializer(), deserializer);
}
}
生产者配置
@Configuration
public class KafkaConfiguration {
@Bean
public ProducerFactory producerConfig() {
Map<String, Object> config = new HashMap();
config.put(ProducerConfig.BOOTSTRAP_SERVERS_CONFIG, "127.0.0.1:9092");
config.put(ProducerConfig.KEY_SERIALIZER_CLASS_CONFIG, StringSerializer.class);
config.put(ProducerConfig.VALUE_SERIALIZER_CLASS_CONFIG, JsonSerializer.class);
return new DefaultKafkaProducerFactory(config);
}
@Bean
public KafkaTemplate kafkaTemplate() {
return new KafkaTemplate(producerConfig());
}
@Bean
public ConcurrentKafkaListenerContainerFactory aaKafkaListenerFactory() {
ConcurrentKafkaListenerContainerFactory<String, AssessmentAttemptDetailsEntity> factory = new ConcurrentKafkaListenerContainerFactory();
factory.setConsumerFactory(assessmentAttemptDetailsEntityConsumerFactory());
return factory;
}
}
推荐答案
您可以通过像这样更改 assessmentAttemptDetailsEntityConsumerFactory()
来将您的包列入白名单:
You can whitelist your package by changing assessmentAttemptDetailsEntityConsumerFactory()
like this:
@Bean
public ConsumerFactory<String, AssessmentAttemptDetailsEntity> assessmentAttemptDetailsEntityConsumerFactory() {
JsonDeserializer<AssessmentAttemptDetailsEntity>
deserializer = new JsonDeserializer<>();
deserializer.addTrustedPackages("com.lte.assessment.assessments");//your package
return new DefaultKafkaConsumerFactory(config,deserializer);
}
