ReplyingKafkaTemplate with KafkaTransactionManager raise Exception

ReplyingKafkaTemplate with KafkaTransactionManager raise Exception - java

I am developing a microservice that needs to make use of synchronous call under transaction with Spring Boot and Kafka.To do this, I use ReplyKafkaTemplate with KafkaTransactionManager. However ReplyKafkaTemplate apparently doesn't work with transactions! The Kafka message needs to be processed transactionally, so it won't be lost in case of failure. However when I add KafkaTransactionManager settings an exception is thrown.
Requirements:
Spring Boot: 2.3.1
Kafka: 2.5.0
Spring Kafka: 2.5.2
Scenario 1:
When adding bean KafkaTransactionManager, the error is thrown during application startup: Error creating bean with name 'kafkaTransactionManager' defined in class path resource.
Configuration:
application.yml
kafka:
bootstrap-servers: localhost:9092
topic:
request-topic: request-topic

}

In the first case, you need a spring prefix:
spring:
kafka:
bootstrap-servers: localhost:9092
topic:
request-topic: request-topic
request-reply-topic: request-reply-topic
consumer-group: request-reply-group
producer:
transactionIdPrefix: "kafka-tx-"
In either case, you need to add #Transactional to the create method so that the transaction manager will start a transaction.
Or, you can use
#ResponseBody
#PostMapping(value=“/coffee/create",produces = MediaType.APPLICATION_JSON_VALUE, consumes = MediaType.APPLICATION_JSON_VALUE)
public Coffee create (#RequestBody Coffee coffee) throws ExecutionException, InterruptedException {
ProducerRecord<String, Coffee> record = new ProducerRecord<String, Coffee>(requestTopic, coffee);
record.headers().add(new RecordHeader(KafkaHeaders.REPLY_TOPIC, requestReplyTopic.getBytes()));
return replyingKafkaTemplate.executeInTransaction(template -> {
requestReplyFuture = replyingKafkaTemplate.sendAndReceive(record);
ConsumerRecord<String, Coffee> consumerRecord = requestReplyFuture.get();
return consumerRecord.value();
});
}
The error seems quite clear:
java.lang.IllegalStateException: No transaction is in process; possible solutions: run the template operation within the scope of a template.executeInTransaction() operation, start a transaction with #Transactional before invoking the template method, run in a transaction started by a listener container when consuming a record
By the way; it's best to use get(timeout, TimeUnit...) on the future, to avoid hanging indefinitely when no reply is returned for some reason.
EDIT
However, this will never work with a consumer with isolation.level=read_committed because the consumer won't see the request until it is committed and we won't commit until the reply is received, which will never happen, so we'll time out and abort the transaction.
sendAndReceive() can simply not be used in a transaction.
The only solution is to do a send and add your own listener to get the reply (and correlate it to a request).

For me your code is working like this:
String WEATHER_URL = "http://api.openweathermap.org/data/2.5/weather?q={city},{country}&APPID={key}&units=metric";
String apiKey = "526a647fcd4f3f465c0340c19d26ef3a";
var x = new UriTemplate(WEATHER_URL).expand("Darmstadt", "Deutschland", apiKey);
System.out.println(x);
Instead of URI I used var so that Java selects proper type.
Your compilation error might be caused by wrong import of URI class.

Problems linking mysql database with java based web app

I am using Spring Data to pull and control data from a mysql database. I have been having problems putting this data into a table. I am using Vaadin and following these tutorials:
https://vaadin.com/learn/tutorials/modern-web-apps-with-spring-boot-and-vaadin/spring-boot-backend-database-jpa-repositories-services
(but am trying to adapt for my own purposes). The tutorial creates an AbstractEntity from which other entities extend. From what I have worked out, this is some form of entity manager which I believe attempts to distinguish unique entities. As I was just attempting to see how all of these objects fit together, I decided to create only one entity and extend it from this AbstractEntity named Stock. This Stock Class is defined as follows:
package com.stockmachine.v2.backend.entity;
import javax.persistence.*;
import javax.validation.constraints.Email;
import javax.validation.constraints.NotEmpty;
import javax.validation.constraints.NotNull;
#Entity
#Table (name="stock_info")
public class Stock extends AbstractEntity implements Cloneable {
#Id
private String Ticker;
private String Region;
public String getTicker() {
return Ticker;
}
public void setTicker(String ticker) {
Ticker = ticker;
}
public String getRegion() {
return Region;
}
public void setRegion(String region) {
Region = region;
}
}
This links to a table in my mysql database named "stock_info", the table has more than two columns but I was only testing, so I decided to only create variables for two of these columns, 'Region' and 'Ticker'. This is just a database with a list of stock tickers and has some information about them, one of the bits of information being the region.
The AbstractEntity is defined as follows:
package com.stockmachine.v2.backend.entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.MappedSuperclass;
#MappedSuperclass
public abstract class AbstractEntity {
}
I also have the following StockService Service defined as follows:
import com.stockmachine.v2.backend.entity.Stock;
import com.stockmachine.v2.backend.repository.StockRepository;
import org.springframework.stereotype.Service;
import java.util.List;
import java.util.logging.Level;
import java.util.logging.Logger;
#Service
public class StockService {
private static final Logger LOGGER = Logger.getLogger(StockService.class.getName());
private StockRepository stockRepository;
public StockService(StockRepository stockRepository) {
this.stockRepository = stockRepository;
}
public List<Stock> findAll() {
return stockRepository.findAll();
}
public long count() {
return stockRepository.count();
}
public void delete(Stock stock) {
stockRepository.delete(stock);
}
public void save(Stock stock) {
if (stock == null) {
LOGGER.log(Level.SEVERE,
"Contact is null. Are you sure you have connected your form to the application?");
return;
}
stockRepository.save(stock);
}
}
and repository:
package com.stockmachine.v2.backend.repository;
import com.stockmachine.v2.backend.entity.Stock;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.Query;
import org.springframework.data.repository.query.Param;
import org.springframework.stereotype.Repository;
import java.util.List;
#Repository
public interface StockRepository extends JpaRepository<Stock, String> {
}
And the main view ui is:
package com.stockmachine.v2.ui;
import com.vaadin.flow.component.orderedlayout.VerticalLayout;
import com.vaadin.flow.router.Route;
import com.stockmachine.v2.backend.entity.Stock;
import com.vaadin.flow.component.grid.Grid;
import com.stockmachine.v2.backend.service.StockService;
#Route("")
public class MainView extends VerticalLayout {
private StockService stockService;
private Grid<Stock> grid = new Grid<>(Stock.class);
public MainView(StockService stockService) {
addClassName("list-view");
setSizeFull();
configureGrid();
add(grid);
updateList();
}
private void configureGrid() {
grid.addClassName("stock-grid");
grid.setSizeFull();
grid.setColumns("ticker","region");
}
private void updateList() {
grid.setItems(stockService.findAll());
}
}
From what I understand (may be completely wrong), the main view will create an instance of the service class StockService which creates an instance of the StockRepository which gets various parameters from the Stock class which is linked to the database table referenced with #Table.This throws the following errors:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'com.stockmachine.v2.ui.MainView': Bean instantiation via constructor failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.stockmachine.v2.ui.MainView]: Constructor threw exception; nested exception is java.lang.NullPointerException: Cannot invoke "com.stockmachine.v2.backend.service.StockService.findAll()" because "this.stockService" is null

I assume this.stockService is null means that the service is not actually collecting any data from my table and thus returning as null. I am not sure if this has something to do with me removing the entity managers functionality. I assume it is just a problem with the service, but I cannot work it out.
I'm not expecting anyone to debug my code considering how much there is, but perhaps if possible, explain to me how all of these resources communicate such that I may be able to debug myself, as I have not been able to find a clear detailed explanation online.
Thanks for any help in advance :)

First problem is that Stock was defining two ids (id form AbstractEntity and Ticker) and is not implementing Serializable.
For the second issue...just add this.stockService = stockService in MainView constructor

[Java| SpringBoot]The Repository is not getting injected

I've been getting into Java again after some years only dealing with javascript and typescript, and I'm trying to get into Spring Boot.
It sounds really fun and convenient, but I'm trying to do something simple and for some reason I can't get my repository to get injected into my service. It sounds something really simple, but I've been digging for hours and can't get it to work.I'm wondering if some of you can help me to understand what I'm doing wrong ,please.
Thanks in advance

The issue is because you did not allow Spring to instantiate CreateProjectService and takes control of the bean, probably you instantiated the object with new CreateProjectService().
The recommended approach is to create an interface e.g. ICreateProjectService like below:
public interface ICreateProjectService {
Projects execute(Projects project);
}
And then implement ICreateProjectService in CreateProjectService like below:
#Service
public class CreateProjectService implements ICreateProjectService {
#Autowired
private IProjectRepository iProjectRepository;
#Override
public Projects execute(Projects project) {
System.out.println("Received " + project.toString());
Projects CreatedProject= this.iProjectRepository.save(project);
System.out.println("Created " + CreatedProject);
return CreatedProject;
}
}
Then in your Controller layer, as an example of the service usage, autowire your service by injecting the interface, like below:
#Restcontroller
#RequestMapping("/api/v1")
public class CreateProjectRest {
#Autowired
private ICreateProjectService iCreateProjectService;
#PostMapping
public Projects execute(Projects project) {
createProjectService.execute(project);
// your code here
}
}
Now Spring is able to recognize CreateProjectService as a concrete implementation, instantiates it as a Spring bean, keeps it in Spring container and make it available for Dependency Injection wherever injected.
Hope this helps out.
UPDATE:
It is more advisable to inject dependencies via constructor than field or setter method.
#Restcontroller
#RequestMapping("/api/v1")
public class CreateProjectRest {
private ICreateProjectService iCreateProjectService;
/* No needed to annotate #Autowired after Spring 4.3.*/
public CreateProjectRest(ICreateProjectService iCreateProjectService){
this.iCreateProjectService = iCreateProjectService;
}
#PostMapping
public Projects execute(Projects project) {
createProjectService.execute(project);
// your code here
}
}

There's too much going on for me to follow, but I think it's simply the case that you can't both create and inject the same bean in the same class.
I.e.
#Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {
#Autowired
private UserDetailsService userDetailsService;
#Bean
public UserDetailsService userDetailsService() {...}
}
won't work. Just think about it, you need UserDetailsService to create the class that's supposed to create UserDetailsService. How would that work?
You can do this instead:
#EnableWebSecurity
#ComponentScan("com")
#Configuration
#EnableGlobalMethodSecurity(prePostEnabled = true)
public class SecurityConfig extends WebSecurityConfigurerAdapter {
#Bean
public UserDetailsService userDetailsService() {
return super.userDetailsService();
}
#Bean
public DaoAuthenticationProvider getDaoAuthenticationProvider() {
DaoAuthenticationProvider authProvider = new DaoAuthenticationProvider();
//call the userDetailsService() method here
authProvider.setUserDetailsService(userDetailsService());
authProvider.setPasswordEncoder(this.passwordEncoder());
return authProvider;
}
...
}
While this looks weird, it does the right thing. Spring proxies all method calls, so when you seemingly call userDetailsService() directly, it actually injects the appropriate bean instead.
