I'm trying to save a large List (+100K items) created from an XLS file with the CrudRepository.saveAll() method. Because of data size, the saveAll method takes a long time to run, so I'm trying to partition the list using Apache Commons Collections ListUtils.partition and calling the saveAll method in a loop, to improve performance:
public interface ClaimsSegmentRepository extends CrudRepository<ClaimsSegment, String> {}
public class FileLoaderService {
#Async("asyncFileLoadExecutor")
public CompletableFuture<List<String>> loadFile(String fileName) throws Exception {
for(List<ClaimsSegment> claimsSegmentGrp : ListUtils.partition(claimsSegmentList, MAX_PARTITION_SIZE)) {
CompletableFuture.supplyAsync(() -> claimSegmentRepo.saveAll(claimsSegmentGrp))
.thenAccept(claimSegmentList -> {
//Processing child objects for Claim Segment List
});
}
}
This is throwing the error HHH000010: On release of batch it still contained JDBC statements, so I read some more online and saw this recommendation for my repo class:
public interface ClaimsSegmentRepository extends CrudRepository<ClaimsSegment, String> {
#Async
<S extends ClaimsSegment> CompletableFuture<S> saveAll()
}
However, that is resulting in a compilation error complaining about return type mismatch:
org.springframework.beans.factory.UnsatisfiedDependencyException:
Error creating bean with name 'loadController':
Unsatisfied dependency expressed through field 'loaderSvc'; nested exception is org.springframework.beans.factory.BeanCreationException:

The #Async annotation works fine for the find methods, but not for save and saveAll. Could someone please point out what I'm doing wrong?
Thanks,
To get a bulk insert with Spring Boot and Spring Data JPA you need only two things:
set the option spring.jpa.properties.hibernate.jdbc.batch_size to appropriate value you need (for example: 20)
use saveAll() method of your repo with the list of entities prepared for inserting.
Working example is here.

These are my classes. They are so basic classes. I don't understand my mistake here. Why can't I create an object?

It looks like you're doing the BetterReads coding series from Java Brains.
The NullPointerException from sessionBuilderCustomizer possibly means that it can't locate your secure connect bundle (SCB). According to Koushik's workshop, you need to place the SCB in the src/main/resources/ directory of your project.
Check that you've configured your project correctly according to the workshop then try to run the app again. Cheers!
I enhanced Application class as a Configuration class and also marked it a #Component so that the provided values can be Autowired in the using code:
#Configuration
#EnableScheduling
#Component
public class BinancebotApplication implements CommandLineRunner {
#Bean
#Primary
#ConfigurationProperties(prefix="chartpatternsignal.datasource")
public DataSource primaryDataSource() {
return DataSourceBuilder.create().build();
}
I tried autowire the above DataSource:
#Configuration
public class ChartPatternSignalDaoImpl {
#Qualifier("chartpatternsignal")
#Autowired
DataSource dataSource;
In my pom.xml I have used the spring-boot-starter-data-jpa.
But it is not working:
Caused by:
org.springframework.beans.factory.NoSuchBeanDefinitionException: No
qualifying bean of type 'javax.sql.DataSource' available: expected at
least 1 bean which qualifies as autowire candidate. Dependency
annotations:
{#org.springframework.beans.factory.annotation.Qualifier(value="chartpatternsignal"),

Why?
You are calling #Qualifier("chartpatternsignal") , however your Datasource is not named that.
It would be #Qualifier("primaryDataSource")
Try:
#Component
public class ChartPatternSignalDaoImpl {
#Qualifier("primaryDataSource")
#Autowired
DataSource dataSource;
or:
#Configuration
public class BinancebotConfiguration {
#Bean
#Primary
#Qualifier("myLovelyDataSource")
#ConfigurationProperties(prefix="chartpatternsignal.datasource")
public DataSource primaryDataSource() {
return DataSourceBuilder.create().build();
}
}
Then autowrite it by qualifier:
#Qualifier("myLovelyDataSource")
#Autowired
DataSource dataSource;
The Springboot Documentation showcases how to create a DataSource using #ConfigurationProperties annotation:
https://docs.spring.io/spring-boot/docs/current/reference/html/howto.html#howto.data-access
Application class
#SpringBootApplication
#EnableScheduling
public class BinancebotApplication implements CommandLineRunner {
}
Configuration Class
#Configuration
public class MyDataSourceConfiguration {
#Bean
#ConfigurationProperties("app.datasource")
public DataSource dataSource() {
return DataSourceBuilder.create().build();
}
}
Service Class
#Service
public class BinanceService {
#Autowired
DataSource dataSource;
}
application.properties
app.datasource.url=jdbc:h2:mem:mydb
app.datasource.username=sa
app.datasource.pool-size=30

Process finished with exit code 0
r2dbc does not support page/slice type, so you can do this:
fun findAllByUserId(userId: Long, pageable: Pageable): Flow<MemberContactableStatusEntity>
And if you need other data(such as totalPage), you need to query again
