**I need a parsed Csv file, I need to upload it to the database.
According to the database structure.**
enter image description here
**
How to implement it?
Sample code please!**
I created a set of classes, according to the structure of the database, but I can not help but connect it all.

I cannot figure out why my converter class is not being called. I have the following Entity class:
import org.springframework.validation.annotation.Validated;
import javax.persistence.Column;
import javax.persistence.Convert;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;
import java.util.List;
#Entity
#Validated
#Table(name = "c_mark", schema="common")
public class CMark {
#Id
#Column(name = "c_mark_id")
private String id;
#Column(name = "cl_fk")
private String cFk;
#Column(name = "s_con")
#Convert(converter = StringListConverterCommaDelim.class)
private List<String> sCon;
#Override
public String toString() {
return "ClassificationMarking{" +
"id='" + id + '\'' +
", cFk='" + cFk + '\'' +
", s_con='" + s_con + '\'' +
'}';
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getCFk() {
return cFk;
}
public void setCFk(String cFk) {
this.cFk = cFk;
}
public List<String> getSCon() {
return sCon;
}
public void setSCon(List<String> sCon) {
this.sCon = sCon;
}
}
Here is the converter class:
import javax.persistence.AttributeConverter;
import javax.persistence.Converter;
import java.util.Arrays;
import java.util.List;
import static java.util.Collections.emptyList;
#Converter
public class StringListConverterCommaDelim implements AttributeConverter<List<String>, String>
{
private static final String SPLIT_CHAR = ",";
#Override
public String convertToDatabaseColumn(List<String> stringList) {
return stringList != null ? String.join(SPLIT_CHAR, stringList) : "";
}
#Override
public List<String> convertToEntityAttribute(String string) {
return string != null ? Arrays.asList(string.split(SPLIT_CHAR)) : emptyList();
}
}
Here is the repo interface that defines the insert method:
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.Modifying;
import org.springframework.data.jpa.repository.Query;
import org.springframework.data.repository.query.Param;
import org.springframework.transaction.annotation.Transactional;
import java.util.List;
public interface CMarkRepository extends JpaRepository <ClassificationMarking, String> {
#Transactional
#Modifying
#Query(value = "INSERT INTO c_mark(c_fk, s_con) " +
"values(:c_fk, :s_con)", nativeQuery = true)
int insertCMark(#Param("c_fk") String c_fk, #Param("s_con") String s_con);
}
, and finally the method that invokes the insert:
public int postCMark(CMark cMark) {
CMark cm = null;
int status = 0;
try {
status = cMarkingRepository.insertCMark(cMark.getCFk(), cMark.getSCon());
} catch ( Exception e) {
e.printStackTrace();
}
return status;
}
My expectation is that the conversion takes place from the insertCMark() call? I am not sure. In any event, the converter is never called. I would be grateful for any ideas. Thanks!
You're not inserting the whole Entity. So I guess from Spring perspective you just give normal String parameters and Spring probably doesn't know the parameter should somehow be converted.
Despite that shouldn't you even get a compile error because you try to call insertCMark(String, String) as insertCMark(String, List<String>)?
Right now I would say that there is no need for some fancy Spring magic.
You can just tweak the getSCon() method to return a String and convert it in there. Or when you need it for something else to create a second method getSConString():
public String getSCon() {
return this.sCon != null ? String.join(SPLIT_CHAR, this.sCon) : "";
}
Another way is to use your current Converter by hand when calling insertCMark:
public int postCMark(CMark cMark) {
CMark cm = null;
int status = 0;
AttributeConverter<List<String>, String> converter = new StringListConverterCommaDelim();
String sCon = converter.convertToDatabaseColumn(cMark.getSCon());
try {
status = cMarkingRepository.insertCMark(cMark.getCFk(), sCon);
} catch ( Exception e) {
e.printStackTrace();
}
return status;
}

Hi elfuso please add path slash example
#RequestMapping(path = "/image")
I have defined custom controllers for my repositories. For example, one looks like this
#RequestMapping(method = RequestMethod.GET, value = "/myEntities")
public ResponseEntity<?> get() {
...TO SOME STUFF
MyEntity myEntity= myEntityRepository.findById(1);
return ResponseEntity.ok(new Resource<>(myEntity));
}
This returns a JSON format data which includes a _links section, where I can get the href to the entity.
Now if I want to return an array of entities which are all resources, I get stuck.
What I have tried so far:
1.
#RequestMapping(method = RequestMethod.GET, value = "/myEntities")
public ResponseEntity<?> get() {
...TO SOME STUFF
List<MyEntity> myEntityList= myEntityRepository.findAll(1);
return ResponseEntity.ok(new Resources<>(myEntityList));
}
2.
#RequestMapping(method = RequestMethod.GET, value = "/myEntities")
public ResponseEntity<?> get() {
...TO SOME STUFF
List<MyEntity> myEntityList= myEntityRepository.findAll();
List<Resource<MyEntity>> resources = new ArrayList<>();
myEntityList.forEach(me -> {
resources.add(new Resource<>(me));
})
return ResponseEntity.ok(resources);
}
Option 1. and 2. don't add _links to the result and I don't understand why. I have googled it a lot and you can add links manually but this seems to be a much clearer way. Can anybody understand, what I'm doing wrong?
There are answers at "adding association links to spring data rest custom exposed method" and "Enable HAL serialization in Spring Boot for custom controller method" for similar questions. I tried something a little different from those answers, for solving a similar situation, and it worked fine. I wish you get your problem solved.
It follows how I did solve my specific situation:
#PostMapping(value = "/myEntities/searchWithParams"
, consumes = MediaType.APPLICATION_JSON_VALUE
, produces = MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<?> searchWithParams(#RequestBody SearchParamsDtoClass params, PersistentEntityResourceAssembler assembler)
{
List<MyEntity> entities = myEntityService.searchWithParams(params);
List<PersistentEntityResource> resourcesList = new ArrayList<PersistentEntityResource>();
for (MyEntity entity: entities) {
PersistentEntityResource resource = assembler.toResource(entity);
resourcesList.add(resource);
}
Resources<PersistentEntityResource> resources = new Resources(resourcesList);
return ResponseEntity.ok(resources);
}
The Resources constructor accepts a collection of embedded content, which is not the same as a collection of links. You have to add the links manually.
Resources resources = new Resources();
resources.add(myEntityRepository
.findAll()
.stream()
.map(entry -> convertToLink(entry)
.collect(Collectors.toList()));
return ResponseEntity.ok(resources);
Here is an example that includes embedded content and pagination in a HAL compliant format.

I created a repository with the following method.
#Modifying(clearAutomatically = true)
#Query(
value = "UPDATE address SET address_line_1 = :#{#address.getAddressLine1()} , address_line_2 = :#{#address.getAddressLine2()} ," +
" address_line_3 = :#{#address.getAddressLine3()} , city = :#{#address.getCity()} , address_type = :#{#address.getAddressType().toString()} ," +
" postal_code = :#{#address.getPostalCode()} , state = :#{#address.getState().toString()} , country= :#{#address.getCountry().toString()} , residence_type = :#{#address.getResidenceType().toString()} ," +
" discriminator = :#{#address.getAddressType().toString()},created_by = :#{#address.getCreatedBy()} , created_date = :#{#address.getCreatedDateTime()} WHERE address_id = :#{#address.getId()}",
nativeQuery = true)
void updateAddress(#Param("address") Address address);
During the updates the addressLine2/ addressLine3 is converted to and stored in the database in hexa format.
For example, if addressLine2 is passed into the method as 1OFFICE OF HOBBITS, it is converted to and stored as \x314f6666696365206f6620486f6262697473
This only occurs on a few updates (not all). I cannot discern a distinguishable pattern among the values that are updated as expected and those that are converted to hexa format.
HELP!!

I even tried without the Spel Expression and I see the same error:

I created a maven entreprise application project, in the ejb module i put my entities in a package and i generated my session beans in an other package and i deployed my ejb module in glassfish,in the web module i added dependencies of spring and I created a controller that search the session bean and call the methode find all() but it doesnt get my objects stored in database, what should i do?
