We had a rogue producer setting a Kafka Header __TypeId__ to a class that was part of the producer, but not of a consumer implemented within a Spring Cloud Stream application using Kafka Streams binder. It resulted in an exception
java.lang.IllegalArgumentException: The class 'com.bad.MyClass' is not in the trusted packages: [java.util, java.lang, de.datev.pws.loon.dcp.foreignmodels.*]. If you believe this class is safe to deserialize, please provide its name. If the serialization is only done by a trusted source, you can also enable trust all (*).
How can we ensure within the consumer that this TypeId header is ignored?
Some stackoverflow answers point to spring.json.use.type.headers=false, but it seems to be an "old" property, that is no more valid.

spring:
json.use.type.headers: false

Here is a unit test
#Test
void consumeWorksEvenWithBadTypesHeader() throws JsonProcessingException, InterruptedException {
Map<String, Object> producerProps = KafkaTestUtils.producerProps(embeddedKafka);
producerProps.put("key.serializer", StringSerializer.class.getName());
DefaultKafkaProducerFactory<String, String> pf = new DefaultKafkaProducerFactory<>(producerProps);
List<Header> headers = Arrays.asList(new RecordHeader("__TypeId__", "com.bad.MyClass".getBytes()));
ProducerRecord<String,String> p = new ProducerRecord(TOPIC1, 0, "any-key",
"{ ... some valid JSON ...}", headers);
try {
KafkaTemplate<String, String> template = new KafkaTemplate<>(pf, true);
template.send(p);
ConsumerRecord<String, String> consumerRecord = KafkaTestUtils.getSingleRecord(consumer, TOPIC2, DEFAULT_CONSUMER_POLL_TIME);
// Assertions ...
} finally {
pf.destroy();
}
}
You have 2 options:
On the producer side set the property to omit adding the type info headers
On the consumer side, set the property to not use the type info headers
https://docs.spring.io/spring-kafka/docs/current/reference/html/#json-serde
It is not an "old" property.
/**
* Kafka config property for using type headers (default true).
* #since 2.2.3
*/
public static final String USE_TYPE_INFO_HEADERS = "spring.json.use.type.headers";
It needs to be set in the consumer properties.

spring-kafka 2.6.7 (downgraded due to issue: https://github.com/spring-cloud/spring-cloud-stream-binder-kafka/issues/1079)
I'm following this recipe to handle deserialisation errors: https://github.com/spring-cloud/spring-cloud-stream-samples/blob/main/recipes/recipe-3-handling-deserialization-errors-dlq-kafka.adoc
I created the beans mentioned in the recipe above as:
Configuration
#Slf4j
public class ErrorHandlingConfig {
#Bean
public ListenerContainerCustomizer<AbstractMessageListenerContainer<byte[], byte[]>> customizer(SeekToCurrentErrorHandler errorHandler) {
return (container, dest, group) -> {
container.setErrorHandler(errorHandler);
};
}
#Bean
public SeekToCurrentErrorHandler errorHandler(DeadLetterPublishingRecoverer deadLetterPublishingRecoverer) {
return new SeekToCurrentErrorHandler(deadLetterPublishingRecoverer);
}
#Bean
public DeadLetterPublishingRecoverer publisher(KafkaOperations bytesTemplate) {
return new DeadLetterPublishingRecoverer(bytesTemplate);
}
}
configuration file:
spring:

value.serializer: myapp.serde.MyCustomSerializer
I was expecting the DLT to be called my-dql.poison. This topic is in fact created fine, however I also get a second topic auto created called some-destination.1.DLT
Why does it create this as well as the one I have named in the config with dlqName ?
What am I doing wrong? When I poll for messages, the message is in the auto created some-destination.1.DLT and not my dlqName
You should not configure dlt processing in the binding if you configure the STCEH in the container. Also set maxAttempts=1 to disable retries there.
You need to configure a destination resolver in the DLPR to use a different name.
/**
* Create an instance with the provided template and destination resolving function,
* that receives the failed consumer record and the exception and returns a
* {#link TopicPartition}. If the partition in the {#link TopicPartition} is less than
* 0, no partition is set when publishing to the topic.
* #param template the {#link KafkaOperations} to use for publishing.
* #param destinationResolver the resolving function.
*/
public DeadLetterPublishingRecoverer(KafkaOperations<? extends Object, ? extends Object> template,
BiFunction<ConsumerRecord<?, ?>, Exception, TopicPartition> destinationResolver) {
this(Collections.singletonMap(Object.class, template), destinationResolver);
}
See https://docs.spring.io/spring-kafka/docs/current/reference/html/#dead-letters
There is an open issue to configure the DLPR with the binding's DLT name.
https://github.com/spring-cloud/spring-cloud-stream-binder-kafka/issues/1031
Is there a way to use #Header inside the following kafka consumer code ? I am using Spring Cloud Stream (Kafka Stream binder implementation), and there after my implemention is using functional model for example.
#Bean
public Consumer<KStream<String, Pojo>> process() {
return messages -> messages.foreach((k, v) -> process(v));
}
If using Spring for apache kafka then this can be as simple as
#KafkaListener(topics = "${mytopicname}", clientIdPrefix = "${myprefix}", errorHandler = "customEventErrorHandler")
public void processEvent(#Header(KafkaHeaders.RECEIVED_MESSAGE_KEY) String key,
#Header(KafkaHeaders.RECEIVED_PARTITION_ID) int partition,
#Header(KafkaHeaders.RECEIVED_TOPIC) String topic,
#Header(KafkaHeaders.RECEIVED_TIMESTAMP) long ts
#Valid Pojo pojo) {
...
// use headers here
...
}
No; the Kafka Streams binder is not based on Spring Messaging.
You can access headers, topic, and such in a Transformer (via the ProcessorContext) added to your stream.
You can use the Kafka Message Channel binder with
#Bean
public Consumer<Message<Pojo>> process() {
return message -> ...
}
I'm trying to test an application with the following binding configured:
spring:
cloud:
stream:
bindings:
accountSource:
destination: account
producer:
useNativeEncoding: true
kafka:
binder:
brokers: ${KAFKA_BOOTSTRAP_ADDRESSES}
producer-properties:
schema.registry.url: ${KAFKA_SCHEMA_REGISTRY_URL}
value.subject.name.strategy: io.confluent.kafka.serializers.subject.RecordNameStrategy
bindings:
accountSource:
producer:
configuration:
key:
serializer: org.apache.kafka.common.serialization.StringSerializer
value:
serializer: io.confluent.kafka.streams.serdes.avro.SpecificAvroSerializer
When running the application normally, AbstractMessageChannel.interceptorList is empty and sending message to broker works fine.
When running the test (with spring-cloud-stream-test-support binder), AbstractMessageChannel.interceptorList gets populated with MessageConverterConfigurer and message is being converted using content-type serialization mechanisms (Avro object is converted to JSON). This is the test code:
#RunWith(SpringRunner.class)
public class AccountServiceImplTest {
#Autowired
private AccountService accountService;
#Autowired
private MessageCollector messageCollector;
#Autowired
private MessageChannel accountSource;
#Test
public void create() {
// Simplified code
AccountCreationRequest accountCreationRequest = AccountCreationRequest.builder().company(company).subscription(subscription).user(user).build();
accountCreationRequest = accountService.create(accountCreationRequest);
Message<?> message = messageCollector.forChannel(accountSource).poll();
// execute asserts on message
}
#TestConfiguration
#ComponentScan(basePackageClasses = TestSupportBinderAutoConfiguration.class)
static protected class AccountServiceImplTestConfiguration {
#EnableBinding({KafkaConfig.AccountBinding.class})
public interface AccountBinding {
#Output("accountSource")
MessageChannel accountSource();
}
}
Am I missing something to disable spring-cloud-stream serialization mechanisms?
Don't use the test binder; use the Kafka binder with an embedded kafka broker instead.
I'm trying to get EJB to work with Glassfish v3. I'm working on a Java EE Web application with Servlets.
When I deploy this web app to Glassfish, it registers the EJB class into the
java:global JNDI tree. But, when I try to inject an instance of this into my
Servlet I got a NameNotFoundException.
When I look at the logs of my server, the Servlet tries to do the look up in java:comp/env.
Can someone help me to solve this?

My guess is that you specified names, mapped names and what have you. This is not needed.
Something like the following should work:
EJB:
#Stateless
public class MyBean {
// ...
}
Servlet:
#WebServlet(urlPatterns="/someurl")
public class MyServlet extends HttpServlet {
#EJB
private MyBean myBean;
#Override
public void service(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// ...
}
}
UPDATE:
After seeing your code, the problem is not the injection of the EJB into the Servlet, but the injection of JpaUserDao in Authenticator.
You are injecting it by class, but this will not work since JpaUserDao implements a business interface: UserDao. Because it implements such an interface, there will be no local-view created. As a result, you have to inject using the interface:
#Stateless
public class Authenticator {
private String userFullName;
private Long userId;
#EJB
private UserDao userDao;
// ...
}
As an extra note, the concept of your Authenticator bean is not going to work. It's a stateless bean and its instance variables will have no meaning to the outside world. Thus, getUserFullName() is not guaranteed to return the result you think it will return. It may happen to work momentarily for you in a test when the container happens to select the same bean instance, but this will not work in general.
Even when you hold on to the reference of an Authenticator, it will still not work. The thing is you get a proxy, and the container will potentially direct every call to it to another instance. Think of it as a URL to servers in a web farm where a browser does a call to. You have no guarantee that two successive will go to the exact same physical server.
The authentication that you're trying to do there should be handled by a bean in the web layer and the authentication details put in the HTTP session (additionally, you should maybe use container authentication as well, but that's a whole other thing that's too off-topic here)
There are several ways for injecting a EJB. The most common and simplest solution would be via Dependency Injection as mentioned Arjan Tijms answer.
Another way would be to get a reference via InitialContext.lookup().
In this approach you can choose which lookup name you pass:
Use the class-name of the declaring Bean-Interface:
String jindiName = BeanInterface.class.getName();
InitialContext ctx = new InitialContext();
BeanInterface bi = ctx.lookup(jndiName);
This also works for a remote lookup from any stand-alone client because the interface is public.
Use the JINDI name of the component naming environment:
String jndiName = "java:comp/env/yourejb"
// same as shown above
This will only work inside the same container because the "outside world" do not have access to to the component naming environment.
For a better understanding of jndi names have a look at this.
I hope this helpes, have Fun!
How do I access a Remote EJB component from a stand-alone java client?
Step 1. Use the no-arg InitialContext() constructor in your code.
The most common problem developers run into is passing specific JNDI bootstrapping properties to InitialContext(args). Some other vendors require this step but GlassFish does not. Instead, use the no-arg InitialContext() constructor.
Step 2. Pass the global JNDI name of the Remote EJB to InitialContext.lookup()
Stand-alone java clients do not have access to a component naming environment (java:comp/env) or to the #EJB annotation, so they must explicitly use the global JNDI name to lookup the Remote EJB. (See here for more information on how global JNDI names are assigned to EJB components) Assuming the global JNDI name of the Remote EJB is "FooEJB" :
For Beans with a 3.x Remote Business interface :
Foo foo = (Foo) new InitialContext().lookup("FooEJB");
Note that in the EJB 3.x case the result of the lookup can be directly cast to the remote business interface type without using PortableRemoteObject.narrow().
For EJB 2.1 and earlier session/entity beans :
Object homeObj = new InitialContext().lookup("FooEJB");
FooHome fooHome = (FooHome)
PortableRemoteObject.narrow(homeObj,FooHome.class);
Foo foo = fooHome.create(...)
Step 3. Include the appropriate GlassFish .jars in the java client's classpath.
For GlassFish 3.
Include $GLASSFISH_HOME/glassfish/lib/gf-client.jar in the client's classpath.
E.g., assuming the application classes are in /home/user1/myclasses and the main client class is acme.MyClient :
java -classpath $GLASSFISH_HOME/glassfish/lib/gf-client.jar:/home/user1/myclasses acme.MyClient
Note that the Java EE 6 API classes are automatically included by gf-client.jar so there is no need to explicitly add javaee.jar to the classpath. gf-client.jar refers to many other .jars from the GlassFish installation directory so it is best to refer to it from within the installation directory itself rather than copying it(and all the other .jars) to another location.
Note: gf-client.jar is located in $GLASSFISH_HOME/modules/gf-client.jar in GlassFish v3.
