Spring-boot TransactionRequiredException: Executing an update/delete query - spring-boot

Question

My service method is annotated with Transnational (org.springframework.transaction.annotation)
But still a "TransactionRequiredException" occurs when making an update on table Persons.
A select on the same table works fine.
#Transactional
public String myMethod(String contractNo){
myRepository.resetValues(contractNo);
}
#Repository
public interface MyRepository extends JpaRepository<Persons, Long> {
#Modifying
#Query(value = "UPDATE PERSONS SET status = 0 WHERE LOGIN_NAME like :contractNo", nativeQuery = true)
void resetValues(#Param("contractNo") String contractNo);
}
#Configuration
#EnableTransactionManagement
#EnableJpaRepositories(
entityManagerFactoryRef = "entityManagerFactory",
transactionManagerRef = "transactionManager",
basePackages = { "com.mypackage.repositories" }
)
public class EBankingDBConfig {
#Bean(name = "dataSource")
#ConfigurationProperties(prefix = "spring.eba-datasource")
public DataSource dataSource() {
return DataSourceBuilder.create().build();
}
#Bean(name = "entityManagerFactory")
public LocalContainerEntityManagerFactoryBean entityManagerFactory(
EntityManagerFactoryBuilder builder,
#Qualifier("dataSource") DataSource dataSource) {
return builder.dataSource(dataSource)
.packages("com.mypackage.model")
.persistenceUnit("myPersistenceUnit")
.build();
}
#Bean(name = "transactionManager")
public PlatformTransactionManager transactionManager(
#Qualifier("entityManagerFactory") EntityManagerFactory
entityManagerFactory) {
return new JpaTransactionManager(entityManagerFactory);
}
}

Answer 1

Because there are multiple TransactionManagers beans defined in the project, you have to annotate transactions of non-primary TransactionaManagers with their names. For example, in my config above, the TransactionManager name is defined as "transactionManager".
So, the Transactional annotation on methods should look line this : #Transactional("transactionManager")
