Rapository在与Kafkalistener的集成测试中无法连接到Postgres(testContainers)
我使用带有Postgres DB的测试容器运行集成测试。当我使用kafkatemplate将JSON消息发送到Kafka主题时,我会得到SQL例外:
[W] SqlExceptionHelper - SQL Error: 0, SQLState: 42P01
[E] SqlExceptionHelper - ERROR: relation "test_db.test_schema" does not exist
could not extract ResultSet; SQL [n/a]; nested exception is org.hibernate.exception.SQLGrammarException: could not extract ResultSet
org.springframework.dao.InvalidDataAccessResourceUsageException: could not extract ResultSet; SQL [n/a]; nested exception is org.hibernate.exception.SQLGrammarException: could not extract ResultSet
我的测试如下:
@Autowired
TestRepository repository;
@Autowired
KafkaTemplate<String, String> kafkaTemplate;
private void publishFile(String fileName) {
kafkaTemplate.send("test.topic", "1", readFile(fileName));
}
@Test
public void test_1() {
publishFile("json/test_1.json");
await().atMost(5, SECONDS).until(()-> repository.findAll().size() == 1);
}
当我调用PublishFile消息时,到达@kafkalistener,
@KafkaListener(topics = "test.topic")
public void onRecieve(@Payload String json, @Header(name = RECIEVED_MESSAGE_KEY) String key) {
TestEntity entity = mapper.readValue(json, TestEntity.class);
repository.save(entity);
}
但是当我直接在类似的测试中使用存储库时:
@Test
public void test_1() {
repository.findAll();
}
一切正常。我可以从存储库写信并阅读。
另外,我可以在此测试中访问存储库:
@Test
public void test_1() {
TestEntity entity = mapper.readValue(readFile("json/test_1.json"), TestEntity.class);
repository.save(entity);
publishFile("json/test_1.json");
log.info(repository.findAll());
await().atMost(5, SECONDS).until(()-> repository.findAll().size() == 1);
}
在主线程中,我可以写入存储库,然后在sendig消息到@kafkalistener之后,我可以从存储库中阅读。但是在@kafkalistener线程中,我不能。我想应该存在相同的测试上下文,但看起来不是。如何使用存储库与@kafkalistener线程中的Postgres容器进行互相关?
I run integrations tests using test containers with Postgres DB. When I send json message to a kafka topic using KafkaTemplate I getting SQL exception:
[W] SqlExceptionHelper - SQL Error: 0, SQLState: 42P01
[E] SqlExceptionHelper - ERROR: relation "test_db.test_schema" does not exist
could not extract ResultSet; SQL [n/a]; nested exception is org.hibernate.exception.SQLGrammarException: could not extract ResultSet
org.springframework.dao.InvalidDataAccessResourceUsageException: could not extract ResultSet; SQL [n/a]; nested exception is org.hibernate.exception.SQLGrammarException: could not extract ResultSet
My test looks like this:
@Autowired
TestRepository repository;
@Autowired
KafkaTemplate<String, String> kafkaTemplate;
private void publishFile(String fileName) {
kafkaTemplate.send("test.topic", "1", readFile(fileName));
}
@Test
public void test_1() {
publishFile("json/test_1.json");
await().atMost(5, SECONDS).until(()-> repository.findAll().size() == 1);
}
When I call publishFile message arrives to a @KafkaListener
@KafkaListener(topics = "test.topic")
public void onRecieve(@Payload String json, @Header(name = RECIEVED_MESSAGE_KEY) String key) {
TestEntity entity = mapper.readValue(json, TestEntity.class);
repository.save(entity);
}
But when I use repository directly in test like this:
@Test
public void test_1() {
repository.findAll();
}
Everything ok. I can write to and read from repository.
Also I have access to a repository in this test:
@Test
public void test_1() {
TestEntity entity = mapper.readValue(readFile("json/test_1.json"), TestEntity.class);
repository.save(entity);
publishFile("json/test_1.json");
log.info(repository.findAll());
await().atMost(5, SECONDS).until(()-> repository.findAll().size() == 1);
}
In main thread I can write to a repository and after sendig message to a @KafkaListener I can read from repository. But In @KafkaListener thread I can not. I suppose there should be the same test context but looks like its not. How can I use repository to interract with Postgres container in @KafkaListener thread?
