How print the entire data structure created with Composite?

I have class-Composite:
public class CompositeText implements ComponentText {
private TypeComponent type;
private String value;
private final List<ComponentText> childComponents;
private CompositeText() {
childComponents = new ArrayList<>();
}
public CompositeText(String value, TypeComponent typeComponent) {
this.value = value;
this.type = typeComponent;
childComponents = new ArrayList<>();
}
#Override
public void add(ComponentText componentText) {
childComponents.add(componentText);
}
#Override
public void remove(ComponentText componentText) {
childComponents.remove(componentText);
}
#Override
public TypeComponent getComponentType() {
return this.type;
}
#Override
public ComponentText getChild(int index) {
return childComponents.get(index);
}
#Override
public int getCountChildElements() {
return childComponents.size();
}
#Override
public int getCountAllElements() {
return childComponents.stream()
.mapToInt(ComponentText::getCountAllElements)
.sum();
}
#Override
public String toString() {
return null;
}
}
I created classes that perform the same action - parsing, parsing text into paragraphs, into sentences, into tokens, into symbols.
public class IntoParagraphParser implements ActionParser {
// call IntoSentenceParser
}
public class IntoSentenceParser implements ActionParser {
// call IntoLexemeParser
}
public class IntoLexemeParser implements ActionParser {
// call IntoSymbolParser
}
public class IntoSymbolParser implements ActionParser {
}
All data is stored in List <ComponentText> childComponents in class-Composite - CompositeText.
How to properly create a method so that it prints all the data that is inside the composite?
I think this will be the method toString() in CompositeText.
Class IntoParagraphParser look:
public class IntoParagraphParser implements ActionParser {
private static final String PARAGRAPH_SPLIT_REGEX = "(?m)(?=^\\s{4})";
private static final IntoParagraphParser paragraphParser = new IntoParagraphParser();
private static final IntoSentenceParser sentenceParser = IntoSentenceParser.getInstance();
private IntoParagraphParser() {
}
public static IntoParagraphParser getInstance() {
return paragraphParser;
}
public ComponentText parse(String text) throws TextException {
ComponentText oneParagraph;
ComponentText componentParagraph = new CompositeText(text, TypeComponent.PARAGRAPH);
String[] arrayParagraph = text.split(PARAGRAPH_SPLIT_REGEX);
for(String element: arrayParagraph) {
oneParagraph = new CompositeText(element, TypeComponent.PARAGRAPH);
oneParagraph.add(sentenceParser.parse(element));
componentParagraph.add(oneParagraph);
}
return componentParagraph;
}
}

Need #Override the method toString() in CompositeText like this:
#Override
public String toString() {
StringBuilder builder = new StringBuilder();
for (ComponentText component : childComponents) {
builder.append(component.toString());
}
return builder.toString();
}
But how to write this code correctly with Stream API?
#Override
public String toString() {
StringBuilder builder = new StringBuilder();
childComponents.stream().map(...????
return builder.toString();
}

All JPA queries fail to find any result(even tho data is present in the MySQL DB)

I'm trying to set up javax.Persistence in my project, and I've started to use the basic approach:
EntityManagerGenerator
package olsa.amex.dao;
import javax.persistence.*;
public class EntityManagerGenerator {
private EntityManager currentSession;
private EntityTransaction currentTransaction;
public EntityManager openCurrentSession() {
if ((currentSession == null)||(currentSession != null && !currentSession.isOpen()))
currentSession = getSessionFactory().createEntityManager();
return currentSession;
}
public EntityManager openCurrentSessionwithTransaction() {
if ((currentSession == null)||(currentSession != null && !currentSession.isOpen()))
currentSession = getSessionFactory().createEntityManager();
currentTransaction = currentSession.getTransaction();
currentTransaction.begin();
return currentSession;
}
public void closeCurrentSession() {
if (currentSession != null && currentSession.isOpen())
currentSession.close();
}
public void closeCurrentSessionwithTransaction() {
if (currentSession != null && currentSession.isOpen()) {
currentTransaction.commit();
currentSession.close();
}
}
private static EntityManagerFactory getSessionFactory() {
EntityManagerFactory entityManager = Persistence.createEntityManagerFactory("JPAAmex");
return entityManager;
}
public EntityManager getCurrentSession() {
return currentSession;
}
public void setCurrentSession(EntityManager currentSession) {
this.currentSession = currentSession;
}
public EntityTransaction getCurrentTransaction() {
return currentTransaction;
}
public void setCurrentTransaction(EntityTransaction currentTransaction) {
this.currentTransaction = currentTransaction;
}
}
ViewAgentSsbDAO(for now I have only implemented findAll and findById)
package olsa.amex.dao;
import java.util.List;
import javax.persistence.TypedQuery;
import com.olsa.amex.entities.ViewAgentssb;
public class ViewAgentSsbDAO implements IGenericDAO<ViewAgentssb,Integer> {
private EntityManagerGenerator hibernateSessionGenerator;
public ViewAgentSsbDAO() {
this.hibernateSessionGenerator = new EntityManagerGenerator();
}
public EntityManagerGenerator getHibernateSessionGenerator() {
return hibernateSessionGenerator;
}
#Override
public void persist(ViewAgentssb entity) throws Exception{
throw new UnsupportedOperationException();
}
#Override
public void update(ViewAgentssb entity) throws Exception {
throw new UnsupportedOperationException();
}
#Override
public ViewAgentssb findById(Integer id) throws Exception{
TypedQuery<ViewAgentssb> query = hibernateSessionGenerator.getCurrentSession().createQuery("from com.olsa.amex.entities.ViewAgentssb as v where v.IDAgent = :id", ViewAgentssb.class);
query.setParameter("id", id);
ViewAgentssb view = query.getSingleResult();
return view;
}
#Override
public void delete(ViewAgentssb entity) throws Exception {
throw new UnsupportedOperationException();
}
#Override
public List<ViewAgentssb> findAll() throws Exception{
List<ViewAgentssb> views = hibernateSessionGenerator.getCurrentSession().createQuery("from com.olsa.amex.entities.ViewAgentssb", ViewAgentssb.class).getResultList();
return views;
}
#Override
public void deleteAll() throws Exception{
throw new UnsupportedOperationException();
}
}
The service class:
package olsa.amex.services;
import java.util.List;
import org.apache.log4j.LogManager;
import org.apache.log4j.Logger;
import com.olsa.amex.entities.ViewAgentssb;
import olsa.amex.dao.ViewAgentSsbDAO;
public class ViewAgentSsbService implements IGenericService<ViewAgentssb,Integer> {
private ViewAgentSsbDAO viewAgentSsbDAO;
private Logger logger = LogManager.getLogger(ViewAgentSsbService.class);
public ViewAgentSsbService() {
this.viewAgentSsbDAO = new ViewAgentSsbDAO();
}
#Override
public void persist(ViewAgentssb entity) throws Exception{
throw new UnsupportedOperationException();
}
#Override
public void update(ViewAgentssb entity) throws Exception{
throw new UnsupportedOperationException();
}
#Override
public ViewAgentssb findById(Integer id) throws Exception {
viewAgentSsbDAO.getHibernateSessionGenerator().openCurrentSession();
ViewAgentssb object = viewAgentSsbDAO.findById(id);
viewAgentSsbDAO.getHibernateSessionGenerator().closeCurrentSession();
return object;
}
#Override
public void delete(ViewAgentssb entity) throws Exception{
throw new UnsupportedOperationException();
}
#Override
public List<ViewAgentssb> findAll() throws Exception{
logger.debug("Sto iniziando la query findAll() per l'entity + " + ViewAgentssb.class);
viewAgentSsbDAO.getHibernateSessionGenerator().openCurrentSession();
List<ViewAgentssb> views = viewAgentSsbDAO.findAll();
logger.debug("La query ha ritornato i seguenti risultati: + " + views.toString());
viewAgentSsbDAO.getHibernateSessionGenerator().closeCurrentSession();
return views;
}
#Override
public void deleteAll() throws Exception{
throw new UnsupportedOperationException();
}
}

And here's the code I used to test out everything:
try {
logger.info("Hibernate test");
ViewAgentSsbService service = new ViewAgentSsbService();
List<ViewAgentssb> entities = service.findAll();
logger.info(entities.toString());
} catch (Exception e1) {
logger.info("Failed... " + e1.getMessage());
ErrorUtility.getError(e1);
}
And the query successfully starts, but it always returns an empty list, even tho there is data present in the MySQL DB.
EDIT: I know I can use the Repositories, but for now I just want to check if everything works as it should.

I found the problem, apparently it was all caused by the wrong jdbc connection string.
In order to generate the entities I used the following string:
jdbc:mysql://rmarjboss-001c.customer.olsa:3306/amex_digital_sbs_dev?useUnicode=yes&characterEncoding=UTF-8
What I used in my persistence.xml is this:
jdbc:mysql://rmarjboss-001c.customer.olsa:3306/amex_digital_sbs_dev
In order for everything to work correctly, I had to set the correct string in my persistence.xml:
jdbc:mysql://rmarjboss-001c.customer.olsa:3306/amex_digital_sbs_dev?useUnicode=yes&characterEncoding=UTF-8

Realm and Expected BEGIN_OBJECT but was NUMBER at path $[0].location.coordinates[0]

I'm trying to store a coordnates (array of double) using Realm-java,but I'm not able to do it.
Here is an example of json that I'm trying to parse:
{"_id":"597cd98b3af0b6315576d717",
"comarca":"string",
"font":null,
"imatge":"string",
"location":{

"type":"Point"
},
"marca":"string",
"municipi":"string",
"publisher":"string",
"recursurl":"string",
"tematica":"string",
"titol":"string"
}
My global object code is like that
public class Images extends RealmObject implements Serializable {
#PrimaryKey
private String _id;
private String recursurl;
private String titol;
private String municipi;
private String comarca;

And Location is a composite of type and a realmlist
Location.java
public class Location extends RealmObject implements Serializable {
private String type;
private RealmList<RealmDoubleObject> coordinates;
public Location() {
}
public String getType() {
return type;
}
public void setType(String type) {
this.type = type;
}
public RealmList<RealmDoubleObject> getCoordinates() {
return coordinates;
}
public void setCoordinates(RealmList<RealmDoubleObject> coordinates) {
this.coordinates = coordinates;
}
}
RealmDoubleObject.java
public class RealmDoubleObject extends RealmObject implements Serializable{
private Double value;
public RealmDoubleObject() {
}
public Double getDoublevalue() {
return value;
}
public void setDoublevalue(Double value) {
this.value = value;
}
}
The error is com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_OBJECT but was NUMBER at path $[0].location.coordinates[0] but I'm not able to figure out why this number is not "fitting" by RealmDoubleObject.
For those that not familiar with realm RealmList doesn't work and you have to build your own realm object.
Thank you. I hope to find some Realm experts here!

SOLVED:
using Gson deserializer it can be done
First we have to initialize the gson object like this
Gson gson = new GsonBuilder()
.setExclusionStrategies(new ExclusionStrategy() {
#Override
public boolean shouldSkipField(FieldAttributes f) {
return f.getDeclaringClass().equals(RealmObject.class);
}
#Override
public boolean shouldSkipClass(Class<?> clazz) {
return false;
}
})
.registerTypeAdapter(new TypeToken<RealmList<RealmDoubleObject>>() {}.getType(), new TypeAdapter<RealmList<RealmDoubleObject>>() {
#Override
public void write(JsonWriter out, RealmList<RealmDoubleObject> value) throws IOException {
// Ignore
}
#Override
public RealmList<RealmDoubleObject> read(JsonReader in) throws IOException {
RealmList<RealmDoubleObject> list = new RealmList<RealmDoubleObject>();
in.beginArray();
while (in.hasNext()) {
Double valor = in.nextDouble();
list.add(new RealmDoubleObject(valor));
}
in.endArray();
return list;
}
})
.create();
And then we have to put some other constructor method
public RealmDoubleObject(double v) {
this.value = v;
}
and this is all.
Thanks for the help #EpicPandaForce

Mybatis There is no getter for property

I'm working with Mybatis to batch insert data,specifically my parameterType is a class,which has a List property,so I use foreach to do the traversal.But it didn't work,here are the debug and codes.Thanks.

the result
org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.reflection.ReflectionException: There is no getter for property named '' in 'class java.lang.String'

IbSnTransit.snList is declared as List of String.class objects so, when you use #{item.sn,jdbcType=VARCHAR} in your mapper you are asked for a property sn in the String.class. Maybe you must use #{item,jdbcType=VARCHAR} instead.

Android Parcelable JsonArray in Side JsonObject

When i am trying Parce this json data with GSON. I am unable to get JsonArray in side of JsonObject. Below is my code, every suggestion will get appriciated.
JSON DATA FROM SERVER :
{
"GetJobDetails": {
"MaxAmount": 0,
"CreatorId": 1,
"JobImages": [
{
"ImagePath": "http://192.168.1.108:8088/Uploads/6e660c0c-4a2b- 42dc-ad97-82cc3efe87a0.jpg",
"JobImageId": 1
},
{
"ImagePath": "http://192.168.1.108:8088/Uploads/ccf1087d-9f7e-4c21-bc61-8aa3fd924e05.jpg",
"JobImageId": 2
},
{
"ImagePath": "http://192.168.1.108:8088/Uploads/4333e8b6-0079-457f-a225-fd7900ea81b1.jpg",
"JobImageId": 3
}
],
}
}
In ACTIVITY :
Gson gson = new Gson();
String response = new String(mresponce);
JobDetails jobDetails= gson.fromJson(response, JobDetails .class);
Log.e("JobDetails ",""+jobDetails.getJobImagesList());
this log prints allways null even when i have images list there in my data.
MODEL CLASS :
public class JobDetails implements Parcelable {
private int MaxAmount;
private int CreatorId;
private List<JobImage> JobImages;
public JobDetails() {
}
public JobDetails(Parcel parcel) {
this.MaxAmount = parcel.readInt();
this.CreatorId= parcel.readInt();
this.JobImages = new ArrayList<JobImage>();
parcel.readTypedList(JobImages, JobImage.CREATOR);
}
// Parcelable
#Override
public int describeContents() {
return 0;
}
#Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeInt(this.MaxAmount);
dest.writeInt(this.CreatorId);
dest.writeList(this.JobImages);
// TODO: Not Parceling AddressList
}
public static final Parcelable.Creator CREATOR = new Parcelable.Creator() {
public JobDetails createFromParcel(Parcel in) {
return new JobDetails(in);
}
public JobDetails[] newArray(int size) {
return new JobDetails[size];
}
};
public List<JobImage> getJobImagesList() {
return JobImages;
}
public void setJobImagesList(List<JobImage> jobImages) {
JobImages = jobImages;
}
public int getMaxAmount() {
return MaxAmount;
}
public void setMaxAmount(int maxAmount) {
MaxAmount= maxAmount;
}
}
ANOTHER MODEL CLASS FOR JOBIMAGE:
public class JobImage implements Parcelable {
private String ImagePath;
private int JobImageId;
JobImage(){
}
public JobImage(Parcel in) {
this.ImagePath = in.readString();
this.JobImageId = in.readInt();
}
// Parcelable
#Override
public int describeContents() {
return 0;
}
#Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeString(this.ImagePath);
dest.writeInt(this.JobImageId);
// TODO: Not Parceling AddressList
}
public static final Creator CREATOR = new Creator() {
public JobImage createFromParcel(Parcel in) {
return new JobImage(in);
}
public JobImage[] newArray(int size) {
return new JobImage[size];
}
};
public String getImagePath() {
return ImagePath;
}
public void setImagePath(String imagePath) {
ImagePath = imagePath;
}
public int getJobImageId() {
return JobImageId;
}
public void setJobImageId(int jobImageId) {
JobImageId = jobImageId;
}
}
Please help me to find what i am doing wrong in this :

Your top-level JSON object is not a JobDetails object, it is an object that has JobDetails member name GetJobDetails. You need to handle this level of your JSON. You can do it with a custom TypeAdapter, or perhaps easier, just make a container object and deserialize it.
class JobDetailContainer {
private JobDetails GetJobDetails;
public JobDetails getJobDetails() {
return GetJobDetails;
}
}
then use --
Gson gson = new Gson();
String response = new String(mresponce);
GetJobDetails getJobDetails= gson.fromJson(response, GetJobDetails.class);
Log.e("JobDetails ",""+getJobDetails.getJobDetails().getJobImagesList());

Agreed with #iagreen ...I should handel top level json object too..this is what i have done after doing some R&D
public class GetJobDetails {
public GetJobDetailsResult getGetJobDetailsResult() {
return GetJobDetailsResult;
}
public void setGetJobDetailsResult(GetJobDetailsResult GetJobDetailsResult) {
this.GetJobDetailsResult = GetJobDetailsResult;
}
}
For Inner Json :
public class GetJobDetailsResult {
private Integer MaxAmount;
private Integer CreatorTotJobPosted;
private List<JobImage> JobImages = new ArrayList<JobImage>();
public Integer getMaxAmount() {
return MaxAmount;
}
public void setMaxAmount(Integer MaxAmount) {
this.MaxAmount = MaxAmount;
}
public Integer getCreatorTotJobPosted() {
return CreatorTotJobPosted;
}
public void setCreatorTotJobPosted(Integer CreatorTotJobPosted) {
this.CreatorTotJobPosted = CreatorTotJobPosted;
}
public List<JobImage> getJobImages() {
return JobImages;
}
public void setJobImages(List<JobImage> JobImages) {
this.JobImages = JobImages;
}
}
Finally For To Hold JobImages
public class JobImage {
private String ImagePath;
private Integer JobImageId;
public String getImagePath() {
return ImagePath;
}
public void setImagePath(String ImagePath) {
this.ImagePath = ImagePath;
}
public Integer getJobImageId() {
return JobImageId;
}
public void setJobImageId(Integer JobImageId) {
this.JobImageId = JobImageId;
}
}
Final Step :
Gson gson = new Gson();
String response = new String(jsonObjectresponce.toString());
GetJobDetails getJobDetails = gson.fromJson(response, GetJobDetails.class);
GetJobDetailsResult result = getJobDetails.getGetJobDetailsResult();
// now result object contains my json data.
