#Repository
public interface Userrepo extends JpaRepository<Users, String> {
}
I want the above interface to be autowired in the below class
#Component
public class Userauth {
#Autowired
Userrepo urepo;
public boolean check(String name,String password) {
Application a=new Application();
Optional<Users> u=urepo.findById(name);
if(!u.isEmpty()) {
Users ud=u.get();
if(ud.getPassword().equals(password))
return true;
}
return false;
}
}
but its giving an error "urepo" is null
in the log getting this.
Ignored because not a concrete top-level class: file [C:\Users\Documents\workspace-spring-tool-suite-4-4.9.0.RELEASE\1Sampleproject\target\classes\com\example\demo\repos\Userrepo.class]

I'm giving this error:
Parameter 0 of constructor in x.microservice.module.business.application.BusinessCreator required a bean of type 'x.microservice.module.business.infrastructure.HibernateJpaRepository' that could not be found.
The injection point has the following annotations:
- #org.springframework.beans.factory.annotation.Autowired(required=false)
Action:
Consider defining a bean of type 'x.microservice.module.business.infrastructure.HibernateJpaRepository' in your configuration.
The controller:
#Slf4j
#RestController
public final class BusinessPostController {
#Autowired
private BusinessCreator creator;
#PostMapping(value = "/business")
public ResponseEntity create(#RequestBody Request request){
BusinessCreatorDto businessCreatorDto = new BusinessCreatorDto(IdentifierEpoch.generate(),request.getName());
return ResponseEntity.ok(
creator.create(businessCreatorDto)
);
}
}
The Application Layer:
#AllArgsConstructor
#Service
public class BusinessCreator {
#Autowired
private HibernateJpaRepository repository;
public BusinessResponse create(BusinessCreatorDto dto){
Business business = new Business(dto.getId(), dto.getName());
repository.save(business);
return BusinessResponse.fromAggregate(business);
}
}
In the Infrastructure layer
#Repository
public abstract class HibernateJpaRepository implements JpaRepository<Business, Long> {
}
The boot Application:
#EnableJpaRepositories
#SpringBootApplication
public class MicroserviceApplication {
public static void main(String[] args) {
SpringApplication.run(MicroserviceApplication.class, args);
}
}
All dependencies are resolved and the others classes I believe that are irrellevant.
Any suggestions? Thank you very much
Probably, the error cause is HibernateJpaRepository - it has to be an interface that extends JpaRepository.
You could write your own Repository in a interface:
#Repository
public interface HibernateJpaRepository extends JpaRepository < Business, Long > {
}
Then your Class:
#AllArgsConstructor
#Service
public class BusinessCreator {
#Autowired
private HibernateJpaRepository repository;
public BusinessResponse create(BusinessCreatorDto dto){
Business business = new Business(dto.getId(), dto.getName());
repository.save(business);
return BusinessResponse.fromAggregate(business);
}
}
Am trying to make a junit test to save data with JPA. Below is my entity class
#Entity
#Table(name="book")
public class test {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name="BOOK_REF_ID",nullable=false)
private int bookRefId;
#Column(name="BOOK_CODE",nullable=false)
private String bookCode;
#Column(name="BOOK_NAME",nullable=false)
private String bookDescription;
public int getBookRefId() {
return bookRefId;
}
public void setBookRefId(int bookRefId) {
this.bookRefId = bookRefId;
}
public String getBookCode() {
return bookCode;
}
public void setBookCode(String bookCode) {
this.bookCode = bookCode;
}
public String getBookDescription() {
return bookDescription;
}
public void setBookDescription(String bookDescription) {
this.bookDescription = bookDescription;
}
}
Service class is
public interface BookService()
{
public Book create(Book book);
}
Repository class is
public interface BookRepository extends
JpaRepository<Book,Integer>
{ }
Service Implementation class is
public BookServiceImpli implements BookService()
{
#Resource
BookRepository repository;
#Override
public Book create(Book book) {
// TODO Auto-generated method stub
return repository.save(book);
}
}
Now my test class is
#RunWith(SpringRunner.class)
#DataJpaTest
#SpringBootTest(classes= {JPAConfig.class})
#AutoConfigureTestDatabase(replace=Replace.NONE)
#TestPropertySource(
locations = "classpath:application.properties")
public class TestBook {
#Autowired
private BookService bookService ;
#Test
public void test() {
Book book = new Book();
book.setBookCode("abc");
book.setBookDescription("safd");
bookService.create(book);
}
Application properties contains password and database details and JPAConfig contain JPA configuration details such as entity scan database details. When am trying to run the test case am getting an error like
A component required a bean of type
'com.repository.sample.BookRepository' that could not be found.
I don't have main method in it.Am new to unit testing please anyone help me to solve the issue.
I'm trying to create a BeanFactory called TaskBeanFactory that I can Autowire into another prototype class that's running on a thread. I want a different instance of a bean returned by the Factory based on a taskName that i want to pass into it but when i start the application i get a null pointer exception because the taskName is null. I had a look at this article but i'm confused about how I should configure the Factory and then pass in the taskName.
The Factory:
import org.springframework.beans.factory.config.AbstractFactoryBean;
import org.springframework.stereotype.Component;
#Data
#Component
#NoArgsConstructor
public class TaskBeanFactory extends AbstractFactoryBean<GenericTask>{
private TaskNameEnum taskName;
public TaskBeanFactory(TaskNameEnum taskName) {
setSingleton(false);
}
#Override
public Class<?> getObjectType() {
return GenericTask.class;
}
#Override
protected GenericTask createInstance() throws Exception {
switch (taskName) {
case FILE_OPERATION:
return new FileTask();
case DATA_OPERATION:
return new DataTask();
default:
return new GenericTask();
}
}
}
The classes used by the Factory:
#Data
public class GenericTask {
private String idTask;
public void executeTask(Work work) {};
}
#Component
#Scope(value="prototype")
public class FileTask extends GenericTask {
#Override
public void executeTask(Work work) {
//some processing
}
}
#Component
#Scope(value="prototype")
public class DataTask extends GenericTask {
#Override
public void executeTask(Work work) {
//some processing
}
}
and the thread that's calling the Factory:
#Slf4j
#Data
#Scope("prototype")
#Component
public class WorkerThread implements Runnable {
#Autowired
private TaskBeanFactory taskBeanFactory;
#Autowired
private DataService dataService;
#Override
public void run() {
//iterate a Map of taskIds from the dataService
taskBeanFactory.setTaskName(TaskNameEnum.valueOf(taskEntry.getKey()));
GenericTask genericTask = taskBeanFactory.getObject();
//expecting genericTask to be of Type FileTask if called with one Key
//or of Type DataTask if called with another
}
}
}
I'd like to create a generic security crud repository and annotate each method with preauthorize, however I cannot get how to retrieve entity class name
#NoRepositoryBean
public interface AbstractEntityRepository<T extends AbstractEntity> extends CrudRepository<T, String> {
#Override
#PreAuthorize("hasPermission(null, #entityName, 'find');
Iterable<T> findAll();
}
public interface UserRepository extends AbstractEntityRepository<User> {}
in this case, entityName is always null.
#Component
#Log
public class CustomPermissionEvaluator implements PermissionEvaluator {
#Override
public boolean hasPermission(Authentication authentication, Serializable targetId, String targetType, Object permission)
log.fine("type " + targetType); // <- null
return true;
}
...
Any idea how to get either "User" or "UserRepository" ?
#Component
public class ClassTypeResolver {
public static String resolve(Object object) {
if (AopUtils.isJdkDynamicProxy(object)) {
try {
return ((SimpleJpaRepository) ((Advised)object).getTargetSource().getTarget()).getDomainClass().getCanonicalName();
} catch (Exception e) {
return null;
}
} else {
return ((SimpleJpaRepository) object).getDomainClass().getCanonicalName();
}
}
}
I have a genericService support classes ( genericService, GenericServiceImpl, GenericDao,GenericHibernateDao) for generic service,dao layer.
Normaly it works fine, When i extend any type parametrized service from abstract generic services.When i extend this extended services in different service it gives:
Caused by: java.lang.ClassCastException: java.lang.Class cannot be cast to java.lang.reflect.ParameterizedType
error.
My GEnericHibernateDao:
#Transactional
public abstract class GenericHibernateDaoSupport extends HibernateDaoSupport implements GenericDaoTemplate
{
private Class type;
public GenericHibernateDaoSupport() {
this.type = (Class<T>) ((ParameterizedType) getClass().getGenericSuperclass()).getActualTypeArguments()[0];
}
#Autowired
#Qualifier(value = "productSessionFactory")
public void bindSessionFactory(SessionFactory sessionFactory)
{
setSessionFactory(sessionFactory);
}
public Class<T> getType() {
return type;
}
public void setType(Class<T> type) {
this.type = type;
}
protected Session getCurrentSession() {
return getHibernateTemplate().getSessionFactory().getCurrentSession();
}
public ID persist(T newInstance) {
return (ID) getHibernateTemplate().save(newInstance);
}
public void update(T transientObject) {
getHibernateTemplate().update(transientObject);
}
Here is my standart extended HibernateDao class:
#Repository
public class StandadHibernateDao extends standardHibernateDaoSupport<Standard, Long> implements StandardDao {
Above extend operation works fine, But when i tried something like this:
#Repository
public class ExtendStandardGatewayHibernateDao extends StandadHibernateDao implements ExtendedStandardDao {
it throws :
Caused by: java.lang.ClassCastException: java.lang.Class cannot be cast to java.lang.reflect.ParameterizedType.
Do you have any idea?
