spring injection bean which inherits from interface

I have config with some #Bean annotations and it works.
But if I change the bean to inherit from interface it isn't work. Do I need special annotations o something like?
config class snippet without imports

Try to use an interface instead of an implementation
DBService service = ctx.getBean(DBService.class);
You have #Transactional annotations on your service methods. All #Transactional annotations should be scanned at startup time and the targeted methods should become transactional. To add transactional behavior Spring creates a proxy for your class. That's why you can't get your bean.

I think,you should make changes in this line DBServiceImpl service = ctx.getBean(DBServiceImpl.class); to DBService service = ctx.getBean(DBService.class);
for reference check spring doc Using the #Bean annotation Spring DOC

"What's important to keep in mind is that, if the transactional bean is implementing an interface, by default the proxy will be a Java Dynamic Proxy. This means that only external method calls that come in through the proxy will be intercepted."
Refer https://www.baeldung.com/transaction-configuration-with-jpa-and-spring.
Following should make it work:
DBService service = ctx.getBean(DBService.class);

Spring Data: Adding custom behavior to single repositories

I've tried to add a custom behaviour to Spring Data repository, but it didn't work.
Dao:
public interface Dao extends JpaRepository<User, Long>, DaoCustom {
}
DaoCustom:
public interface DaoCustom {
User create(User user);
}
DaoCustomImpl:
#Repository
#Transactional
public class DaoCustomImpl implements DaoCustom {
#PersistenceContext
private EntityManager em;
#Override
public User create(User user) {
em.persist(user);
return user;
}
}
MainClass:
public class SpringDataJPAMain {
public static void main(String[] args) {
ApplicationContext context = new AnnotationConfigApplicationContext(RootConfig.class);
Dao dao = context.getBean(Dao.class);
}
}
When I run MainClass, the following exception is thrown:

What's wrong? According to Spring's tutorial it should work fine.

For implementing your custom repository in Spring Data Repository, you have to follow Spring naming conventions. So try this:
#Repository
#Transactional
public class DaoImpl implements DaoCustom {
#PersistenceContext
private EntityManager em;
#Override
public User create(User user) {
em.persist(user);
return user;
}
}
Your custom repository implementation class name should be 'MainRepositoryClassName' + 'Impl'

Spring - trouble with injecting validator bean

i couldn't find solution for my problem anywhere.
I'm trying to make validation working in spring web flow form. I need to
set validator in configuration, however it's located in another config file
and it seems spring can't find proper bean. How can I achieve successful injection here?
As far as I know, Autowiring should inject bean into validator reference.
Maybe it has something to do with order of loading configuration classes?
WebConfig.java:
#Configuration
#Import(godziszewski.patryk.ElectronicsStore.config.FlowConfiguration.class)
#EnableWebMvc
#ComponentScan(basePackages = "godziszewski.patryk")
public class WebConfig extends WebMvcConfigurerAdapter {
....
#Bean
public LocalValidatorFactoryBean validator()
{
LocalValidatorFactoryBean lv = new LocalValidatorFactoryBean();
lv.setValidationMessageSource(messageSource());
return lv;
}
}
FlowConfiguration.java:
#Configuration
public class FlowConfiguration extends AbstractFlowConfiguration {
#Autowired
Validator validator;
....
#Bean
public FlowBuilderServices flowBuilderServices()
{
FlowBuilderServices fbs = new FlowBuilderServices();
fbs.setValidator(validator);
return fbs;
}
}
The error i'm getting:
org.springframework.beans.factory.UnsatisfiedDependencyException:
Error creating bean with name 'flowConfiguration':
Unsatisfied dependency expressed through field 'validator':
No qualifying bean of type [org.springframework.validation.Validator] found for dependency [org.springframework.validation.Validator]:
expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {#org.springframework.beans.factory.annotation.Autowired(required=true)};
nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException:

expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {#org.springframework.beans.factory.annotation.Autowired(required=true)}
Im using spring 4.3.2.RELEASE
However, when I delete Validator dependency from FlowAdapter.class I get error :
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'flowBuilderServices' defined in class path resource [godziszewski/patryk/ElectronicsStore/config/FlowConfiguration.class]: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: The ViewFactoryCreator is required

Full FlowConfiguration class code, maybe I'm doing something wrong?
package godziszewski.patryk.ElectronicsStore.config;

import org.springframework.webflow.executor.FlowExecutor;
import org.springframework.webflow.mvc.servlet.FlowHandlerAdapter;
import org.springframework.webflow.mvc.servlet.FlowHandlerMapping;
#Configuration
public class FlowConfiguration extends AbstractFlowConfiguration {
#Bean
public FlowDefinitionRegistry flowRegistry() {
return getFlowDefinitionRegistryBuilder()
.setBasePath("/WEB-INF/flows")
.setFlowBuilderServices(flowBuilderServices())
.addFlowLocationPattern("/**/*-flow.xml")
.build();
}
#Bean
public FlowExecutor flowExecutor() {
return getFlowExecutorBuilder(flowRegistry()).build();
}
#Bean
public FlowHandlerMapping flowHandlerMapping()
{
System.out.println("flowconfig");
FlowHandlerMapping fh = new FlowHandlerMapping();
fh.setFlowRegistry(flowRegistry());
return fh;
}
#Bean
public FlowHandlerAdapter flowHandlerAdapter()
{
FlowHandlerAdapter fh = new FlowHandlerAdapter();
fh.setFlowExecutor(flowExecutor());
return fh;
}
#Bean
public FlowBuilderServices flowBuilderServices()
{
FlowBuilderServices fbs = new FlowBuilderServices();
//fbs.setValidator(validator);
return fbs;
}
}
If i delete .setFlowBuilderServices(flowBuilderServices()) method, everything works fine
EDIT: I managed to get this working by deleting #Configuration annotation form flow config class, now it looks like this:
//#Configuration
public class FlowConfiguration extends AbstractFlowConfiguration {
#Autowired
Validator validator;
...
#Bean
public FlowBuilderServices flowBuilderServices()
{
System.out.println(validator.toString());
FlowBuilderServices fbs = new FlowBuilderServices();
fbs.setValidator(validator);
return fbs;
}
And now I can use injected LocalValidatorBean in this class.

I interpret that eventually you need a FlowBuilderServices which has a reference to Validator bean.
This can be achieved by using the Autowired tag inside FlowBuilderServices
public class FlowBuilderServices{
#Autowired
Validator validator
...
}
And then in FlowConfiguration you just need to define the bean
#Bean
public class FlowBuilderServices flowBuilderServices()
{
FlowBuilderServices fbs = new FlowBuilderServices();
return fbs;
}

Is there an unresolvable circular reference

When I start my application using springboot, an exception occurs. I have no idea about it.
#Bean

}
#Bean
#ConfigurationProperties(prefix = "slave1.datasource")

DynamicDataSource dataSource = new DynamicDataSource();
dataSource.setMaster(master());
List<DataSource> slaves = new ArrayList<DataSource>();
slaves.add(slave1());
dataSource.setSlaves(slaves);
return dataSource;
}
Here is DynamicDataSource class structure

private AtomicInteger counter = new AtomicInteger();

Error creating bean in Spring boot [duplicate]

This question already has answers here:
java.lang.ClassNotFoundException: org.aspectj.util.PartialOrder$PartialComparable

Closed 4 years ago.
i created an app based on spring boot and spring boot data , so i want to use
HSQLDB in memory
This is my Application Class :
package boot;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
#SpringBootApplication()
public class Application {
public static void main(String[] args) {
SpringApplication.run(Config.class);
}
}
and this is Config class :
#Configuration
#EnableAutoConfiguration
#EnableJpaRepositories
#ComponentScan(basePackages = {"controller", "dao", "service"})
#EnableTransactionManagement
class Config {
#Bean(name = "dataSource")
public DataSource dataSource() {
EmbeddedDatabaseBuilder builder = new EmbeddedDatabaseBuilder();
return builder.setType(EmbeddedDatabaseType.HSQL).build();
}
#Bean(name = "entityManager")
public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
vendorAdapter.setDatabase(Database.HSQL);
vendorAdapter.setGenerateDdl(true);
LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();
factory.setJpaVendorAdapter(vendorAdapter);
factory.setPackagesToScan(getClass().getPackage().getName());
factory.setDataSource(dataSource());
return factory;
}
#Bean
public PlatformTransactionManager transactionManager() {
return new JpaTransactionManager();
}
}
as you khnow in the these three packages "controller", "dao", "service" there are
some #Autowired
when i run the Application, i got this error :

What's wrong with it ?
