I'm using MySQL and Hibernate. I've added record to Receiving table and have id and barcode fields as foreign keys in transaction table rcid and barcode.
When I search a specific record using id:
int id =(Integer)defaultTableModel.getValueAt(jReceivingsTable.getSelectedRow(),0);
Receivings receivings = manager.searchReceivingsId(id);
that doesn't null, printing id return appropriate value so why I'm getting null when I set it to Transaction table?
Rctransaction rctransaction = new Rctransaction();
rctransaction.getReceivings().getId().setId(id); // here id has value
rctransaction.getReceivings().getId().setBarcode(barcode);
rctransaction.setReceivings(receivings);
Here are classes :

You are instantiating the Hibernate objects in the wrong order.
First you need a ReceivingsId :
ReceivingsId rid = new ReceivingsId (id, barcode);
Then add this rid to a Receivings:
Receivings rec = new Receivings();
rec.setId(rid);
And finally set it to the Rctransaction:
Rctransaction rctransaction = new Rctransaction();
rctransaction.setReceivings(rec);
If you try to call getReceivings after instantiating the object without setting it before you'll always get a NullPointerException. To avoid this, you can instantiate the Receivings object in the Rctransaction constructor.

In debug mode, string response in objectMapper shows correct response, string response in attractionMainResponse giving a success but can't map the attractionDetailModel, giving null.
Is this about a Jackson ObjectMapper? Is it possible to create a smaller example, that makes it easier to give a solution.
I'm creating the grid view with array list of category and un categorized product model class. Now I want to sort the list by date or name. See below my code.
Here this is my adapter.
public class CommonAdapter extends BaseAdapter {

private LayoutInflater inflator = null;
private List<Object> list;
public CommonAdapter(Context mContext, List<Object> list) {
super();
this.mContext = mContext;

}
#Override
public Object getItem(int position) {

}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
convertView = inflator.inflate(R.layout.row_categories, null);
holder = new ViewHolder();
holder.layout_bg = (RelativeLayout) convertView.findViewById(R.id.grid_bg);

This is product model classes
public class Product {
String id;
String name;
String price;
String createAt;
public Product(String id, String name, String price, String createAt) {
this.id = id;
this.name = name;
this.price = price;
this.createAt = createAt;
}
public String getId() {
return id;
}
public void setId(String id) {

}
public String getName() {

}
public void setName(String name) {
this.name = name;
}
public String getPrice() {
return price;
}
public void setPrice(String price) {
this.price = price;
}
public String getCreateAt() {
return createAt;
}
public void setCreateAt(String createAt) {
this.createAt = createAt;
}
}
This is Category Model
public class Category {
String id;
String name;
String createAt;
public Category(String id, String name, String createAt) {
this.id = id;
this.name = name;
this.createAt = createAt;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getCreateAt() {
return createAt;
}
public void setCreateAt(String createAt) {
this.createAt = createAt;
}
}
In MainActivity.java
CommonAdapter commonAdapter = new CommonAdapter(getActivity(), commonArrayList);
grid_common.setAdapter(commonAdapter);
Here I tried with comparator, it's comes with object only!
Collections.sort(commonArrayList, new Comparator<Object>() {
#Override
public int compare(Object o1, Object o2) {
return 0;
}
});
See here both models have createAt and name fields, So I want to sort by createAt or by name in this ArrayList.
Create another object model class and add all method and variable there is in two separate class...
and set data manually then... using for loop and any other ..that suitable for you...
and you this third created object model for sorting your data...
Edited
Eg:
first class
class first{
String f_name,l_name;
public String getF_name() {
return f_name;
}
public void setF_name(String f_name) {
this.f_name = f_name;
}
public String getL_name() {
return l_name;
}
public void setL_name(String l_name) {
this.l_name = l_name;
}
}
Second class
public class second {
String f_name,l_name,m_name;
public String getF_name() {
return f_name;
}
public void setF_name(String f_name) {
this.f_name = f_name;
}
public String getL_name() {
return l_name;
}
public void setL_name(String l_name) {
this.l_name = l_name;
}
public String getM_name() {
return m_name;
}
public void setM_name(String m_name) {
this.m_name = m_name;
}
}
third class
public class third{
String f_name,l_name,m_name;
public String getF_name() {
return f_name;
}
public void setF_name(String f_name) {
this.f_name = f_name;
}
public String getL_name() {
return l_name;
}
public void setL_name(String l_name) {
this.l_name = l_name;
}
public String getM_name() {
return m_name;
}
public void setM_name(String m_name) {
this.m_name = m_name;
}
}
set all value of first and second into third...
and use third class for setup data and sorting data
Here is my advice:
public class Category {
String id;
String name;
String createAt;
...
}
public class Product extends Category{
String price;
....
}
Collections.sort(commonArrayList, new Comparator<Category>() {
#Override
public int compare(Category o1, Category o2) {
if(o1.getCreateAt()>o2.getCreateAt()){
return 1;
}else{
...
}
return 0;
}
});
Create an abstract class, put fields common in Product and Category and compare that class.
public abstract class BaseClass {
private String id;
private String name;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
Your Public class:
public class Product extends BaseClass {
...
public Product(String id, String name, String price, String createAt) {
setId(id);
setName(name);
this.price = price;
this.createAt = createAt;
}
}
Category class:
public class Category extends BaseClass {
...
public Category(String id, String name, String createAt) {
setId(id);
setName(name);
this.createAt = createAt;
}
}
And compare like this:
Collections.sort("ArrayList<BaseClass>()", new Comparator<BaseClass>() {
#Override
public int compare(BaseClass baseClass, BaseClass t1) {
return baseClass.getName().compareTo(t1.getName());
}
});
If you wanna sort by date put date field to BaseClass.
Thanks for your advice. I found the answer. I just make class casting on the object inside the comparator.
See the code below,
Collections.sort(commonArrayList, new Comparator<Object>() {
#Override
public int compare(Object o1, Object o2) {
int res = 0;
if (o1 instanceof Category && o2 instanceof Category) {
res = (((Category) o1).getName().compareTo(((Category) o2).getName()));
} else if (o1 instanceof Product && o2 instanceof Product) {
res = (((Product) o1).getName().compareTo(((Product) o2).getName()));
} else if (o1 instanceof Category && o2 instanceof Product) {
res = (((Category) o1).getName().compareTo(((Product) o2).getName()));
} else if (o1 instanceof Product && o2 instanceof Category) {
res = (((Product) o1).getName().compareTo(((Category) o2).getName()));
}
return res;
}
});
If you have any simplified ideas, kindly post here..
Hope this sample solution in java may help :
Create an interface let say Data as follows
public interface Data {
}
Create the model classes as follows :
Product
public class Product implements Data{
String id;
String name;
String price;
String createAt;
public Product(String id, String name, String price, String createAt) {
this.id = id;
this.name = name;
this.price = price;
this.createAt = createAt;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPrice() {
return price;
}
public void setPrice(String price) {
this.price = price;
}
public String getCreateAt() {
return createAt;
}
public void setCreateAt(String createAt) {
this.createAt = createAt;
}
}
Category
public class Category implements Data{
String id;
String name;
String createAt;
public Category(String id, String name, String createAt) {
this.id = id;
this.name = name;
this.createAt = createAt;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getCreateAt() {
return createAt;
}
public void setCreateAt(String createAt) {
this.createAt = createAt;
}
}
Now in main class of the project
public class TestSorting {
public static void main(String args[]) {
ArrayList<Data> categories = new ArrayList<>();
ArrayList<Data> products = new ArrayList<Data>();
// For Product

I am getting data from gemfire
List<String> objects = restTemplate.getForObject(geodeURL+"/gemfire-api/v1/queries/adhoc?q=SELECT * FROM /region s",List.class);
which is like below:
[('price':'119','volume':'20000','pe':'0','eps':'4.22','week53low':'92','week53high':'134.4','daylow':'117.2','dayhigh':'119.2','movingav50day':'115','marketcap':'0','time':'2015-11-25 05:13:34.996'), ('price':'112','volume':'20000','pe':'0','eps':'9.22','week53low':'92','week53high':'134.4','daylow':'117.2','dayhigh':'119.2','movingav50day':'115','marketcap':'0','time':'2015-11-25 05:13:34.996'), ('price':'118','volume':'20000','pe':'0','eps':'1.22','week53low':'92','week53high':'134.4','daylow':'117.2','dayhigh':'119.2','movingav50day':'115','marketcap':'0','time':'2015-11-25 05:13:34.996')]
This is a list of String I am getting.Currently I have 3 values in list.
I have a pojo class like below:

How do I create a List of StockInfo class object from the value I am getting from restTemplate.getForObject
I think you could just use:
List<StockInfo> objects = restTemplate.getForObject(geodeURL+"/gemfire-api/v1/queries/adhoc?q=SELECT * FROM /region s",List.class);
I'm having trouble trying to understand how realm.io persist/save objects.
I have 3 Objects (Inventory, InventoryItem and Product);
When I create a Inventory containing InventoryItems it works fine until i close the app. When i re-open the app all InventoryItems loses the reference to Product and start to show "null" instead.
Strange thing is all other attributes like Inventory reference to InventoryItem is persisted fine. Just problem with Products.
this is how i'm trying to do:
Model
Product
public class Product extends RealmObject {
#PrimaryKey
private String id;
#Required
private String description;
private int qtdUnityType1;
private int qtdUnityType2;
private int qtdUnityType3;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
public int getQtdUnityType1() {
return qtdUnityType1;
}
public void setQtdUnityType1(int qtdUnityType1) {
this.qtdUnityType1 = qtdUnityType1;
}
public int getQtdUnityType2() {
return qtdUnityType2;
}
public void setQtdUnityType2(int qtdUnityType2) {
this.qtdUnityType2 = qtdUnityType2;
}
public int getQtdUnityType3() {
return qtdUnityType3;
}
public void setQtdUnityType3(int qtdUnityType3) {
this.qtdUnityType3 = qtdUnityType3;
}
}
Inventory
public class Inventory extends RealmObject {
#PrimaryKey
private String id;
#Required
private String type;
#Required
private Date createdAt;
#Required
private String status;
public String getStatus() {
return status;
}
public void setStatus(String status) {
this.status = status;
}
private RealmList<InventoryItem> listItems;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getType() {
return type;
}
public void setType(String type) {
this.type = type;
}
public Date getCreatedAt() {
return createdAt;
}
public void setCreatedAt(Date createdAt) {
this.createdAt = createdAt;
}
public RealmList<InventoryItem> getListItems() {
return listItems;
}
public void setListItems(RealmList<InventoryItem> listItems) {
this.listItems = listItems;
}
}
InventoryItem
public class InventoryItem extends RealmObject {
#PrimaryKey
private String idItem;
private Inventory inventory;
private Product product;
public Product getProduct() {
return product;
}
public void setProduct(Product product) {
this.product = product;
}
private Date expirationDate;
private int qtdUnityType1;
private int qtdUnityType2;
private int qtdUnityType3;
private int qtdDiscard;
public String getIdItem() {
return idItem;
}
public void setIdItem(String idItem) {
this.idItem = idItem;
}
public Inventory getInventory() {
return inventory;
}
public void setInventory(Inventory inventory) {
this.inventory = inventory;
}
public Date getExpirationDate() {
return expirationDate;
}
public void setExpirationDate(Date expirationDate) {
this.expirationDate = expirationDate;
}
public int getQtdUnityType1() {
return qtdUnityType1;
}
public void setQtdUnityType1(int qtdUnityType1) {
this.qtdUnityType1 = qtdUnityType1;
}
public int getQtdUnityType2() {
return qtdUnityType2;
}
public void setQtdUnityType2(int qtdUnityType2) {
this.qtdUnityType2 = qtdUnityType2;
}
public int getQtdUnityType3() {
return qtdUnityType3;
}
public void setQtdUnityType3(int qtdUnityType3) {
this.qtdUnityType3 = qtdUnityType3;
}
public int getQtdDiscard() {
return qtdDiscard;
}
public void setQtdDiscard(int qtdDiscard) {
this.qtdDiscard = qtdDiscard;
}
}
and finally one of the millions ways i tried to persist
realm.beginTransaction();
Inventory inventory = realm.createObject(Inventory.class);
inventory.setId(id);
inventory.setCreatedAt(new DateTime().toDate());
if (radioGroup.getCheckedRadioButtonId() == R.id.rbInventario) {
inventory.setType("Inventário");
} else {
inventory.setType("Validade");
}
inventory.setStatus("Aberto");
RealmList<InventoryItem> inventoryItems = new RealmList<>();
RealmResults<Product> productsRealmResults = realm.allObjects(Product.class);
for (int i = 1; i <= productsRealmResults.size(); i++) {
InventoryItem item = realm.createObject(InventoryItem.class);
item.setIdProduct(productsRealmResults.get(i - 1).getId() + " - " + productsRealmResults.get(i - 1).getDescription());
item.setProduct(productsRealmResults.get(i - 1));
item.setIdItem(i + "-" + id);
item.setInventory(inventory);
item = realm.copyToRealmOrUpdate(item);
item = realm.copyToRealmOrUpdate(item);
inventoryItems.add(item);
}
inventory.setListItems(inventoryItems);
realm.copyToRealmOrUpdate(inventory);
realm.commitTransaction();
I already looked trough some answers here like this one:
stack answer
and the Java-examples (person, dog, cat)
provided with the API
but I can't understand how to properly insert this.
The problem is that you are setting a list of InventoryItem elements which are not added to the Realm database.
Change InventoryItem item = new InventoryItem(); to InventoryItem item = realm.createObject(InventoryItem.class);
Also, the inventoryItems themselves aren't stored in Realm db. Add realm.copyToRealmOrUpdate(inventoryItems) after the loop.
I have the following POJO classes
#JsonIgnoreProperties(ignoreUnknown = true)
public class GroupUser {

I am using jackson library to serialize the Group Object to JSON like below:
ObjectMapper mapper = new ObjectMapper();
mapper.configure(SerializationFeature.WRITE_EMPTY_JSON_ARRAYS, true);
return mapper.writeValueAsString(group);
But the Users fields never gets serialized, no matter what groupUsers always is an empty array []. Any idea what am I doing wrong?
