DBUnit NoSuchColumnException in parent class - spring

So I'm getting this error:
org.dbunit.dataset.NoSuchColumnException: TOYOTA.CAR_MAKE - (Non-uppercase input column: CRTE_DT_TM) in ColumnNameToIndexes cache map. Note that the map's column names are NOT case sensitive.
when trying to populate a H2 DB using DbUnit in the context of a Spring JUnit test. The DDL for the H2 DB is created from JPA-annotated classes. However, the column does exist, it is in an abstract class that is extended by the core class.
Let me explain. The core JPA class looks like this:
#Entity
#Table(name = "TOYOTA")
public class Toyota extends Car {
#Id
#Column(name = "TOYOTA_REF")
private String toyotaRef;
#Column(name = "TOYOTA_DEALER")
private String toyotaDealer;
// etc.
The parent class looks like this:
public abstract class Car {
#Column(name = "CAR_MAKE")
private String carMake;
#Column(name = "CAR_MODEL")
private String carModel;
I'm initiating tests like this:
#RunWith(SpringJUnit4ClassRunner.class)
#ContextConfiguration(locations = "classpath:/test-spring-config.xml") // Load Spring Test context
#TestExecutionListeners({DependencyInjectionTestExecutionListener.class,
TransactionalTestExecutionListener.class,
DbUnitTestExecutionListener.class}) // Used to load test data onto DB})
#DatabaseSetup(value = {"classpath:/integrationTestData/Toyota.xml"})
#Test
#Transactional
public void testSomething() {
and my Toyota.xml data file looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<dataset>
<TOYOTA TOYOTA_REF="TOY123"
TOYOTA_DEALER="Big Dealer"
CAR_MAKE="Toyota"
CAR_MODEL="Corolla"
/>
</dataset>
Any thoughts?

Fixed this myself. I had to add this JPA annotation to the parent class:
import javax.persistence.MappedSuperclass;
#MappedSuperclass
public abstract class Car {

Spring can't find implementation

Here is my folder structure:
In my IAppUserMapper I have a method to convert every AppUser entity instance to Data Transfer Object Model. Here is the code in IAppUserMapper interface:
import com.server.ecommerceapp.dto.AppUserDTO;
import com.server.ecommerceapp.model.AppUser;
import org.mapstruct.Mapper;
import org.mapstruct.Mapping;
import org.mapstruct.factory.Mappers;
#Mapper
public interface IAppUserMapper {
IAppUserMapper appUserMapper = Mappers.getMapper(IAppUserMapper.class);
#Mapping(target = "username")
#Mapping(target = "email")
#Mapping(target = "password")
#Mapping(target = "roles", expression = "java(appUser.getRoles().stream().map(this::getRoleName).collect(Collectors.toList()))")
AppUserDTO toAppUserDTO(AppUser appUser);
default String getRoleName(Role role) {
return role.getRoleName();
}
}
And here is the MapperConfiguration class code where I configure both Product and user mappers:
import com.server.ecommerceapp.mapper.IAppUserMapper;
import com.server.ecommerceapp.mapper.IProductMapper;
import org.mapstruct.factory.Mappers;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
#Configuration
public class MapperConfiguration {
#Bean
public IAppUserMapper appUserMapper() {
return Mappers.getMapper(IAppUserMapper.class);
}
#Bean
public IProductMapper productMapper() {
return Mappers.getMapper(IProductMapper.class);
}
}
The error I get:
Error creating bean with name 'appUserMapper' defined in class path
resource
[com/server/ecommerceapp/configuration/MapperConfiguration.class]:
Bean instantiation via factory method failed; nested exception is
org.springframework.beans.BeanInstantiationException: Failed to
instantiate [com.server.ecommerceapp.mapper.IAppUserMapper]: Factory
method 'appUserMapper' threw exception; nested exception is
java.lang.RuntimeException: java.lang.ClassNotFoundException: Cannot
find implementation for com.server.ecommerceapp.mapper.IAppUserMapper
I was told I should make META-INF package in resources, with service package and the com.server.ecommerceapp.mapper.AppUserMapper txt with the content same as the name of the file, so that Spring can scan and find the package following the path:
src/main/resources/META-INF/service/com.server.ecommerceapp.mapper.AppUserMapper
but it didnt work. Any ideas how to solve this, and by the way, is it bad practise to start interface names with capital I cause Im coming from ASP?
Edit:
I added #Mapper(componentModel = "spring") to my interfaces and implemented them as DI with Autowired. I dont know if its related to that problem that I had but now I get error that it cant find collectors. Im trying to map a collection of Roles from AppUser to AppUserDTO. Here are both AppUser and AppUserDTO classes:
#Entity
#NoArgsConstructor
#AllArgsConstructor
#Data
public class AppUser {
#Id
#GeneratedValue(strategy = IDENTITY)
private Long id;
#Column(name = "username", nullable = false, unique = true)
private String username;
#Column(name = "email", nullable = false, unique = true)
private String email;
#Column(name = "password", nullable = false)
private String password;
#ManyToMany(fetch = EAGER)
private Collection<Role> roles;
}
And DTO:
#NoArgsConstructor
#AllArgsConstructor
#Data
public class AppUserDTO {
private String username;
private String email;
private String password;
private Collection<String> roles;
}
So you're using Spring, but you are trying to not use Spring.
You should make your mappers use Spring component model:
#Mapper(componentModel = "spring")
public interface MyMapper {
Target map(Source source);
}
Check docs for dependency injection: https://mapstruct.org/documentation/stable/reference/html/#using-dependency-injection
Or do it with shared configuration: https://mapstruct.org/documentation/stable/reference/html/#shared-configurations
After that you can just #Autowired MyMapper myMapper; as any other Spring bean. No need to create instance in interface (the "Mappers.getMapper" thing) and no need to create mappers in java configuration, bean creation will be handled by framework.
#Mapping(target = "roles", expression = "java(appUser.getRoles().stream().map(this::getRoleName).collect(Collectors.toList()))")
now I get error that it cant find collectors
You are using an expression with Collectors class. As stated in the documentation https://mapstruct.org/documentation/stable/reference/html/#expressions:
Please note that the fully qualified package name is specified because MapStruct does not take care of the import of the TimeAndFormat class (unless it’s used otherwise explicitly in the SourceTargetMapper). This can be resolved by defining imports on the #Mapper annotation.
So you either need to fully qualify java.util.stream.Collectors in your expression or set "imports" parameter in #Mapper annotation: #Mapper(imports = Collectors.class).
I would also say, you could just write a normal Java method for roles mapping and not be dealing with expressions. But that's up to your taste.
The file name of the service should be the interface and its content the implementation. You have named it by the implementation.

How to make Set using spring-data-aerospike

Environment:
spring-boot v2.0.4 RELEASE
spring-data-aerospike v2.0.1.RELEASE
java - 8
Here are my application code and properties.
// application.properties
aerospike.hosts=xxx:3000
aerospike.namespace=test
// aerospike configuration class
#Configuration
#RequiredArgsConstructor
#EnableConfigurationProperties(AerospikeConfiguration.AerospikeConfigurationProperties.class)
#EnableAerospikeRepositories(basePackageClassses = TestAeroRepository.class)
public class AerospikeConfiguration extends AbstractAerospikeDataConfiguration {
private final AerospikeConfigurationProperties aerospikeConfigurationProperties;
#Override
protected Collection<Host> getHosts() {
return Host.parseServiceHosts(aerospikeConfigurationProperties.getHosts());
}
#Override
protected String nameSpace() {
return aerospikeConfigurationProperties.getNamespace();
}
#Data
#Validate
#ConfigurationProperties("aerospike")
public static class AerospikeConfigurationProperties {
#NotEmpty
String hsots;
#NotEmpty
String namespace;
}
}
# Entity class
#Value
#Document
#Builder(toBuilder = true)
#AllArgsConstructor
public class testEntity() {
#Id
int id;
#Field
String name;
#Field
String timestamp;
}
#Repository
public interface TestAeroRepository extends AerospikeRepository<TestEntity, Integer> {
}
public interface TestAeroService {
void save();
}
#Service
#RequiredArgsConstructor
public class TestAeroServiceImpl implements TestAeroService {
private final TestAeroRepository testAeroRepository;
#Override
public void save(TestEntity entity) {
testAeroRepository.save(entity);
}
}
I checked Aerospike client connection has no problem.
But error is occurred when save() method is executed.
org.springframework.cglib.core.ReflectUtils.defineClass(Ljava/lang/String;[BLjava/lang/ClassLoader;Ljava/security/ProtectionDomain;Ljava/lang/Class;)Ljava/lang/Class;
Have to make sets before execute the application? I didn't make sets.
Any problem with my code?
You’re using an old version of spring-data-aerospike (2.0.1.RELEASE was released on April 2019) is there any chance you can upgrade to the latest version? 2.4.2.RELEASE
You can see how to setup a simple spring data aerospike application here: https://medium.com/aerospike-developer-blog/simple-web-application-using-java-spring-boot-aerospike-database-and-docker-ad13795e0089
Please share the entire project’s code and the entire exception.
I would look into:
The configuration class (The Aerospike Beans creation).
The content of the testEntity class - are you using #Id annotation on the primary key field?
Extending the repository class with specifying the testEntity object (… extends AerospikeRepository<testEntity, Object> {) you can see an example in the link I added.
The set is automatically created and takes the name of your object class, which is testEntity in your case. For example, based on your code, if you do not specify a collection in the #Document annotation a set named "testEntity" will automatically be created. I added the #Document(collection = "testEntitys") annotation and all I did was create two set. Once you insert your first record, run the "SHOW SETS" aql command and it will be there. So that's one way to do it.

Spring JPA Test - InvalidDataAccessResourceUsageException

I have an entity
#Data
#Entity
#Table(name = "VGI_TRADESDBO.TRADELOG")
public class TradeLog {
#Id
#Column(name="TRADE_ID")
private Long tradeId;
…
And a Repository
public interface TradeLogRepository extends JpaRepository<TradeLog, Long>{
And a schema.sql file
CREATE SCHEMA "VGI_TRADESDBO"
CREATE TABLE "VGI_TRADESDBO"."TRADELOG"
( "TRADE_ID" NUMBER(38,0),
Finally I have a cucumber step def that injects that Repository and tries to save to it
#DataJpaTest
#Sql({"schema.sql"})
public class TradesToTsoStep{
#Inject TradeLogRepository tradeLogRepo;
and yet I get a Column "TRADELOG0_.TRADE_ID" not found;
org.springframework.dao.InvalidDataAccessResourceUsageException: could not prepare statement
Has anyone run into this? And why is it sticking the 0_ into the column name?

Spring Data JPA and Generics

I have an entity that looks like this
#Entity(name = "encounter_pdf_export")
public class EncounterPDFExport<T extends Encounter> implements Serializable {
public static final long serialVersionUID = 1L;
#Id
#GeneratedValue
private Long pdfExportId;
#Any(metaColumn = #Column(name = "encounter_type"))
#Cascade(CascadeType.ALL)
#AnyMetaDef(
idType = "long",
metaType = "string",
metaValues = {
#MetaValue(value = "FooEncounter", targetEntity = FooEncounter.class)
})
#JoinColumn(name = "encounter_id")
private T encounter;
The abstract type that I'm extending is:
public abstract class Encounter {
public abstract Long getEncounterId();
}
Here is my Spring Data Repository
#Repository
public interface EncounterPDFExportRepository extends PagingAndSortingRepository<EncounterPDFExport, Long> {
EncounterPDFExport findOneByEncounter_encounterId(#Param("encounterId") Long encounterId);
}
I am getting a stack trace when starting up the application related to to the findOneByEncounter_encounterId method:

I am assuming that either Spring Data JPA doesn't support abstracted/generic fields? If that's the case, would creating a #Query be a sufficient workaround?
Not sure if this will be helpful to anyone, but I did get this working.
Removed the abstract class and made it an interface with a single public getEncounterId() method
Modified FooEncounter to implement the above interface
Removed generics from the EncounterPDFExport class
Modified the encounter field to utilize the above interface rather than a generic
Apparently, I'm hitting some Hibernate bug/limitation when accessing fields within FooEncounter. Accessing Encounter within EncounterPDFExport works OK, though. I modified my Spring Data JPA Repository to look like the following (note the modification from finding by encounter.encounterId vs. just encounter):
#Repository
public interface EncounterPDFExportRepository extends PagingAndSortingRepository<EncounterPDFExport, Long> {
EncounterPDFExport findOneByEncounter(#Param("encounter") Encounter encounter);
}
The Hibernate bug in question seems to be related to https://jira.spring.io/browse/DATAJPA-836.

Hibernate and JPA always load referenced tables

I am working with Hibernate 4+ Spring MVC + Spring Data with JPA annotations:
#Entity
public class ClassOne implements Serializable{
......
#OneToMany(mappedBy = "mapper", fetch=FetchType.LAZY)
private Set<ClassTwo> element = new HashSet<ClassTwo>(0);
//more fields
//getters and setters
//equals and hashcode
}
#Entity
public class ClassTwo implements Serializable{
......
#ManyToOne(fetch=FetchType.LAZY)
#JoinColumn(name = "CEN_CEN_CODIGO", nullable = false)
private ClassOne classOne;
//more fields
//getters and setters
//equals and hashcode
}
public interface ClassOneRepository extends CrudRepository<ClassOne, Long> {
#Override
#Query("select c from ClassOne c")
public List<ClassOne> findAll();
}
#Service
public class ClassOneService {
#Autowired
private ClassOneRepository classOneRepository;
#Transactional(readOnly=true)
public List<ClassOne> findAll() {
return classOneRepository.findAll();
}
}
And finally I call thie service from my #Controller
#Autowired
ClassOneService classOneService;
I expect results ONLY from ClassOne but retrieving the JOIN values with ClassTwo and all the database tree associate. Is it possible to get only values for ONE table using this schema? Is it a cache problem or Fetching not LAZY?
EDIT: I added the relatioship between two classes
Thank you
You must have the following anotation above your Set<ClassTwo> or its getter:
#OneToMany(fetch = FetchType.LAZY, ...)
See http://docs.oracle.com/javaee/7/api/javax/persistence/OneToMany.html#fetch()
It seems to be that simple "SELECT *" JPA query returns all eagerly fetched fields for the entity.
Please refer to: JPA - Force Lazy loading for only a given query
and http://forcedotcom.github.io/java-sdk/jpa-queries.
So my solution would be to use SessionFactory to get current session and then use "classic" method
return getCurrentSession().createCriteria(persistentClass).list();
Another possible way is to create let's say a POJO object without Set which uses the same table as ClassOne.
I've just added #Lazy for each #ManyToOne and #OneToMany relationship. It seems that Spring Data needs Spring annotations but I supposed that just was necessary to add fetch = FetchType.LAZY. No more Eager behaviours ;).
Thanks for your responses
