Error handling in SpringBoot kafka in Batch mode

Asked 2021-Jun-15 at 17:34

I am trying to figure out is there any way to send failed records in Dead Letter topic in Spring Boot Kafka in Batch mode. I don't want to make the records being sent in duplicate as it's consuming in batch and few are already processed. I saw this link ofspring-kafka consumer batch error handling with spring boot version 2.3.7

I thought about a use case to stop container and start again without using DLT but again the issue of duplication will come in Batch mode.

@Garry Russel can you please provide a small code for batch error handling.

...

ANSWER

Answered 2021-Jun-15 at 17:34

The RetryingBatchErrorHandler was added in spring-kafka version 2.5 (which comes with Boot 2.3).

The listener must throw an exception to indicate which record in the batch failed (either the complete record, or the index in the list).

Offsets for the records before the failed one are committed and the failed record can be retried and/or sent to the dead letter topic.

See https://docs.spring.io/spring-kafka/docs/current/reference/html/#recovering-batch-eh

There is a small example there.

The RetryingBatchErrorHandler was added in 2.3.7, but it sends the entire batch to the dead letter topic, which is typically not what you want (hence we added the RetryingBatchErrorHandler).

Regarding the error

I'm assuming you have missing dependencies on your code generation class path. Once you update your question, I'll update my answer.

Regarding jOOQ code generation support for @TypeDef etc.

jOOQ won't support your generated composite types in generated code out of the box, you'll still have to add forced type configurations for that, possibly embeddable type configurations:

Note that the JPADatabase offers a quick win by integrating with simple JPA defined schemas very quickly. It has its caveats. For best results, I recommend going DDL first (and generate both jOOQ code and JPA model from that), because it will be much easier to put your schema change management under version control, e.g. via Flyway or Liquibase.

properties not loaded from external configuration, when additional config location is provided from command line

Asked 2021-Jun-15 at 10:31

I am using spring-boot 2.2.7.RELEASE

In the controller I want to get some values from external config file. But the application does not start even though the properties are available in the external config.

could you suggest how to load only specific properties from external config.

As per documentation, SpringApplication converts any command line option arguments (that is, arguments starting with --, such as --server.port=9000) to a property and adds them to the Spring Environment.

-D works when running via maven. Try: java -jar application.jar --spring.config.location=file:///C://your//path//config.yml.

Via maven: mvn spring-boot:run -Dspring.config.location="file:///C://your//path//config.yml"

How to use Annotations in a Spring Boot Library (without Main Class)?

Asked 2021-Jun-14 at 17:20

I am new to spring boot and trying to figure out some of its working. Here I am getting Null Pointer Exception for the below implementation. I am not sure can we use @Autowire annotation for a Library project without a Main class. Maybe this sounds stupid,I believe we can do a @ComponentScan for the Library Project from a Service project that's created.My Question is looking at the below implementation is there any possibility to use annotation in the below library project, because Annotations are throwing NullPointerException for the below code?

ANSWER

With SpringBootApplication annotation, It will create application context with all required beans when starting the application. The object will be injected whenever it needed.

But in the Normal java application, the Object will be created while calling the new keyword.

@SpringBootApplication it required when you have @Autowired annotation otherwise you will get error.

how does spring boot auto configure the driver of a special datasource?

Asked 2021-Jun-14 at 09:03

Without spring boot ,we must specify the detail of a data source,right?

...

ANSWER

Answered 2021-Jun-14 at 08:59

From DataSource Configuration in the docs:

Spring Boot can deduce the JDBC driver class for most databases from the URL. If you need to specify a specific class, you can use the spring.datasource.driver-class-name property.

So start without configuring anything and just putting the JDBC driver on the classpath. If it would not work, you can manually configure it.

Your test is a junit4-api based. But from your pom.xml you have junit5 dependencies.

Removing jupiter dependencies should do the trick.

Regarding cobertura, as you run on java 8 preferably you should migrate to JaCoCo as cobertura with java version higher than 7 is buggy.
