I am using neo4j-cypher-dsl-codegen-sdn6 to generate a static model to use in Cypher-DSL.
This is my source #Node

val name: String,
var born: Int
) {
#JsonCreator
constructor(#JsonProperty("name") name: String, #JsonProperty("born") born: Int) : this(null, name, born) {
}
}

public final class Person_ extends NodeBase<Person_> {

I would have expected that the UUID gets generated.
Please can someone try to replicate this error, or advise if there is another way to generate the UUID.
I have a spring-boot application and I use DTO like that:
Service
#Service
public class UnitOfMeasureServiceImpl implements IUnitOfMeasureService {
private final IUnitsOfMeasureRepository unitOfMeasureRepository;
#Autowired
public UnitOfMeasureServiceImpl(IUnitsOfMeasureRepository unitOfMeasureRepository) {
this.unitOfMeasureRepository = unitOfMeasureRepository;
}
#Override
public UnitOfMeasureDTO getUnitOfMeasureById(UUID id) {
Optional<UnitOfMeasure> optionalUnitOfMeasure = unitOfMeasureRepository.findById(id);
if (!optionalUnitOfMeasure.isPresent()){
// throw new ComponentNotFoundException(id);
return null;
}
return UnitOfMeasureDTO.factory(optionalUnitOfMeasure.get());
}
dto:
#Data
#JsonInclude(JsonInclude.Include.NON_NULL)
public class UnitOfMeasureDTO {
private String id;
private String name;
private String description;
private String sourceInfoCompanyName;
private String originalId;
public static UnitOfMeasureDTO factory(UnitOfMeasure unitOfMeasure) {
UnitOfMeasureDTO dto = new UnitOfMeasureDTO();
dto.id = unitOfMeasure.getId().toString();
dto.name = unitOfMeasure.getName();
dto.description = unitOfMeasure.getDescription();
dto.sourceInfoCompanyName = unitOfMeasure.getSourceInfo().getSourceCompany().getName();
dto.originalId = unitOfMeasure.getOriginalId();
return dto;
}
}
controller:
#RestController
#RequestMapping(UnitOfMeasureController.BASE_URL)
public class UnitOfMeasureController {
public static final String BASE_URL = "/api/sust/v1/unitOfMeasures";
private final IUnitOfMeasureService unitOfMeasureService;
public UnitOfMeasureController(IUnitOfMeasureService unitOfMeasureService) {
this.unitOfMeasureService = unitOfMeasureService;
}
#GetMapping(path = "/{id}")
#ResponseStatus(HttpStatus.OK)
public UnitOfMeasureDTO getUnitOfMeasureDTO(#PathVariable("id") UUID id) {
UnitOfMeasureDTO unitOfMeasureDTO = unitOfMeasureService.getUnitOfMeasureById(id);
return unitOfMeasureDTO;
}
So in my service I have getUnitOfMeasureById(UUID id) that return a UnitOfMeasureDTO.
Now I need to call, from another service, getUnitOfMeasureById(UUID id) that return the domain entity UnitOfMeasure. I think it's correct to call a service method from another service (not a controller method!) and the separation between business logic is at the service layer. So is it correct to have 2 methods: getUnitOfMeasureDTOById and getUnitOfMeasureById in the service? (getUnitOfMeasureDTOById call getUnitOfMeasureById to avoid code duplication)
This is my Data Repository file and i used native query to retrieve all data address(Locations) of Data. I called the function using Postman and I got null outputs of locations. This my first time of using Native query and its really impossible to solve these errors

Spring won't return you only address using below query. It still return you DATA object
public interface DataRepository extends JpaRepository<Data, Long> {
#Query(value = "SELECT dataAddress FROM Data")
List<DataProject> getDataAddress();
}
for fetching only DataAddress you need to create a constructor inside Data model for DataAddress only
public Data(String dataAddress) {
this.dataAddress = dataAddress;
}
and your query will look like this:
public interface DataRepository extends JpaRepository<Data, Long> {
#Query(value = "SELECT new Data(dataAddress) FROM Data")
List<DataProject> getDataAddress();
}
Update 1 :
if you need this for other fields with same datatype and then above 'constructor' based method fails. There are some other alternatives:
You can fetch DATA object and use java stream map function to extract only 1 field. data.stream().map((data) -> data.getDataAddress()).collect(Collectors.toList())
You can use native SQL query to fetch only required fields.
#Query(value = "SELECT d.data_address FROM CCCData d", nativeQuery=true)
I am creating REST API using spring framework. My entity is based on one table and REST API is supposed to be invoked using POST operation with below JSON structure. Can someone explain me how to map the entity class so that it can consume below-shown json.
Since my entity is based on only one table, I am not able to understand how can it create nested json objects for same table properties.
{
"process_ar_receipt": {
"message_header": {
"source_system_guid": "DDED-DBCD-REV-E1F4343DB3434",
"source_system": "MeSo_TravelAds"
},
"receipt_header": {
"customer_number": "123",
"source_receipt_number": "TESTRCPT_1523",
}
}
}
you could use Gson to convert the json to a DTO
https://jarroba.com/gson-json-java-ejemplos/
pseudo code
assuming your Entity class as
#Entity(name="foo")
class Data{
#Id
private String source_system_guid;
#Column
private String source_system;
#Column
private String customer_number;
#Column
private String source_receipt_number;
public Data() {}
public Data(String ssId, String sourceSystm, String custNum, String srcRcptNum) {
this.source_system_guid = ssId;
this.source_system = sourceSystm;
this.customer_number = custNum;
this.source_receipt_number = srcRcptNum;
}
public String getSource_system_guid() {
return source_system_guid;
}
public void setSource_system_guid(String source_system_guid) {
this.source_system_guid = source_system_guid;
}
public String getSource_system() {
return source_system;
}
public void setSource_system(String source_system) {
this.source_system = source_system;
}
public String getCustomer_number() {
return customer_number;
}
public void setCustomer_number(String customer_number) {
this.customer_number = customer_number;
}
public String getSource_receipt_number() {
return source_receipt_number;
}
public void setSource_receipt_number(String source_receipt_number) {
this.source_receipt_number = source_receipt_number;
}
}
Now since your DTO/BO i.e. Data Transfer Object or Business Object is different from the actual entity we will create the required BO object as below
class DataTO{
#JsonProperty("process_ar_receipt")
private ReceiptTO receiptTO=new ReceiptTO();
public ReceiptTO getReceiptTO() {
return receiptTO;
}
public void setReceiptTO(ReceiptTO receiptTO) {
this.receiptTO = receiptTO;
}
}
class ReceiptTO{
#JsonProperty("message_header")
private MessageHeader messageHeder = new MessageHeader();
#JsonProperty("receipt_header")
private ReceiptHeader receiptHeder = new ReceiptHeader();
public MessageHeader getMessageHeder() {
return messageHeder;
}
public void setMessageHeder(MessageHeader messageHeder) {
this.messageHeder = messageHeder;
}
public ReceiptHeader getReceiptHeder() {
return receiptHeder;
}
public void setReceiptHeder(ReceiptHeader receiptHeder) {
this.receiptHeder = receiptHeder;
}
}
class MessageHeader{
#JsonProperty("source_System_Guid")
private String sourceSystemId;
#JsonProperty("system_Id")
private String systemId;
public String getSourceSystemId() {
return sourceSystemId;
}
public void setSourceSystemId(String sourceSystemId) {
this.sourceSystemId = sourceSystemId;
}
public String getSystemId() {
return systemId;
}
public void setSystemId(String systemId) {
this.systemId = systemId;
}
}
class ReceiptHeader{
#JsonProperty("customer_number")
private String customerNumber;
#JsonProperty("source_rcpt_number")
private String sourceReceiptNumber;
public String getCustomerNumber() {
return customerNumber;
}
public void setCustomerNumber(String customerNumber) {
this.customerNumber = customerNumber;
}
public String getSourceReceiptNumber() {
return sourceReceiptNumber;
}
public void setSourceReceiptNumber(String sourceReceiptNumber) {
this.sourceReceiptNumber = sourceReceiptNumber;
}
}
The #JsonProperty annotation is imported from org.codehaus.jackson.annotate.JsonProperty; i.e from jackson jar
Now a Simple Test class to demo DTO/BO back and forth Entity conversion
public class Test{
public static void main(String[] args) throws JsonGenerationException, JsonMappingException, IOException {
List<Data> datas = new ArrayList<Data>();
datas.add(new Data("DDED-DBCD-REV-E1F4343DB3434","MeSo_TravelAds","123","TESTRCPT_1523"));
datas.add(new Data("ADED-EWQD-REV-E1F4343YG3434","FooSo_MusicAds","132","TESTRCPT_1523"));
datas.add(new Data("YDED-YUTR-REV-E1F43UIDB3434","BarSo_HealthAds","143","TESTRCPT_1523"));
List<DataTO> dataTOs = new ArrayList<DataTO>();
for (Data data : datas) {
DataTO dataTO = new DataTO();
dataTO.getReceiptTO().getMessageHeder().setSourceSystemId(data.getSource_system_guid());
dataTO.getReceiptTO().getMessageHeder().setSystemId(data.getSource_system());
dataTO.getReceiptTO().getReceiptHeder().setCustomerNumber(data.getCustomer_number());
dataTO.getReceiptTO().getReceiptHeder().setSourceReceiptNumber(data.getSource_receipt_number());
dataTOs.add(dataTO);
}
ObjectMapper mapper = new ObjectMapper();
String str = mapper.writeValueAsString(dataTOs);
System.out.println(str);
}
}
This will give you below result
[
{
"process_ar_receipt":{
"message_header":{
"source_System_Guid":"DDED-DBCD-REV-E1F4343DB3434",
"system_Id":"MeSo_TravelAds"
},
"receipt_header":{
"customer_number":"123",
"source_rcpt_number":"TESTRCPT_1523"
}
}
},
{
"process_ar_receipt":{
"message_header":{
"source_System_Guid":"ADED-EWQD-REV-E1F4343YG3434",
"system_Id":"FooSo_MusicAds"
},
"receipt_header":{
"customer_number":"132",
"source_rcpt_number":"TESTRCPT_1523"
}
}
},
{
"process_ar_receipt":{
"message_header":{
"source_System_Guid":"YDED-YUTR-REV-E1F43UIDB3434",
"system_Id":"BarSo_HealthAds"
},
"receipt_header":{
"customer_number":"143",
"source_rcpt_number":"TESTRCPT_1523"
}
}
}
]
similarly the other conversion
String input = "{ \r\n" +
" \"process_ar_receipt\":{ \r\n" +
" \"message_header\":{ \r\n" +
" \"source_System_Guid\":\"ADED-EWQD-REV-E1F4343YG3434\",\r\n" +
" \"system_Id\":\"FooSo_MusicAds\"\r\n" +
" },\r\n" +
" \"receipt_header\":{ \r\n" +
" \"customer_number\":\"132\",\r\n" +
" \"source_rcpt_number\":\"TESTRCPT_1523\"\r\n" +
" }\r\n" +
" }\r\n" +
" }";
DataTO dataTO = mapper.readValue(input, DataTO.class);
System.out.println(dataTO.getReceiptTO().getMessageHeder().getSourceSystemId());
System.out.println(dataTO.getReceiptTO().getMessageHeder().getSystemId());
System.out.println(dataTO.getReceiptTO().getReceiptHeder().getCustomerNumber());
System.out.println(dataTO.getReceiptTO().getReceiptHeder().getSourceReceiptNumber());
this will print
ADED-EWQD-REV-E1F4343YG3434
FooSo_MusicAds
132
TESTRCPT_1523
You dont have to use the mapper code you can directly add the jackson converter as HttpMessageConverted which will convert the JSON to java object automatically
#Configuration
#EnableWebMvc
public class WebConfiguration extends WebMvcConfigurerAdapter {
... other configurations
#Override
public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
Jackson2ObjectMapperBuilder builder = new Jackson2ObjectMapperBuilder();
builder.serializationInclusion(JsonInclude.Include.NON_NULL);
builder.propertyNamingStrategy(PropertyNamingStrategy.CAMEL_CASE_TO_LOWER_CASE_WITH_UNDERSCORES);
builder.serializationInclusion(Include.NON_EMPTY);
builder.indentOutput(true).dateFormat(new SimpleDateFormat("yyyy-MM-dd"));
converters.add(new MappingJackson2HttpMessageConverter(builder.build()));
converters.add(new MappingJackson2XmlHttpMessageConverter(builder.createXmlMapper(true).build()));
}
}
Get data from a derived class..
My samples.
public class Maintest
{
public string name = "2";
}
public class test : Maintest
{
string bla = name;
}
or
public class test : Maintest
{
test child = new test();
string bla = child.name;
}
Please reply

For example there is the main class
and I have a derived class that will output data of the first class.
As an example, I just wanted to pass the value of the derivative in the main class. For a proper understanding
If you return the field from a property, it might look a little something like this.
using System;
public class Program
{
public void Main()
{
var test = new Test();
Console.WriteLine(test.greeting);
}
}
// make this abstract if you're never directly instantiate MainTest
public abstract class MainTest
{
public string name = "world";
}
public class Test : MainTest
{
public string greeting {get { return "Hello " + name;}}
}
http://dotnetfiddle.net/R8kwh3
Also, you can enforce a contract by doing something like
public abstract class MainTest
{
public string name = "world";
// create an abstract property to ensure it gets implemented in the inheriting class
public abstract string greeting {get; private set;}
}
public class Test : MainTest
{
public override string greeting {get { return "Hello " + name;}}
}
Maybe you want get data in method? Therefore, you can use this:
public class test : Maintest
{
public string GetData()
{
return name;
}
}
