How to properly use JPA/Hibernate?

How to properly use JPA/Hibernate? - java

I'm trying to understand annotations better with JPA / Hibernate and SQL Server.
I created a simple project: an abstract class named "Articles". Two classes inherit it: Ramette which adds a weight and Pen which adds a color. The code below is not working and I am unable to correct the errors. Do you have an idea? Thank you!

This makes not much sense. This exception is only thrown when you have a discriminator in the table that has no match in the entity model. Maybe you have trailing spaces in the table?

I am trying to map the entities using #OneToOne as a bidirectional mapping but getting weird exceptions

These are the exceptions I keep on getting repeatedly until I stop the server

Here is Catalog Entity(Catalog.java)

public Catalog() {
}
public Catalog(int skuCode, String skuName, String skuDesc, String bName, String bDesc, Supplier supplier) {
super();
this.skuCode = skuCode;
this.skuName = skuName;
this.skuDesc = skuDesc;

return "Catalog [skuCode=" + skuCode + ", skuName=" + skuName + ", skuDesc=" + skuDesc + ", bName=" + bName

}
}
Here is the Supplier Entity(Supplier.java)
package com.inventory.entities;
import javax.persistence.CascadeType;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.OneToOne;
import javax.persistence.PrimaryKeyJoinColumn;
import javax.persistence.Table;
#Entity
#Table(name = "supplier")
public class Supplier {
#Id
#Column(length = 50)
private int supplierId;
#Column(length = 50)
private String supplierName;
#OneToOne(mappedBy = "supplier",fetch = FetchType.LAZY)
private Catalog catalog;
public Supplier() {
}
public Supplier(int supplierId, String supplierName, Catalog catalog) {
super();
this.supplierId = supplierId;
this.supplierName = supplierName;
this.catalog = catalog;
}
public int getSupplierId() {
return supplierId;
}
public void setSupplierId(int supplierId) {
this.supplierId = supplierId;
}
public String getSupplierName() {
return supplierName;
}
public void setSupplierName(String supplierName) {
this.supplierName = supplierName;
}
public Catalog getCatalog() {
return catalog;
}
public void setCatalog(Catalog catalog) {
this.catalog = catalog;
}
#Override
public String toString() {
return "Supplier [supplierId=" + supplierId + ", supplierName=" + supplierName + ", catalog=" + catalog + "]";
}
}
Now my Requirement is that I want to get the Catalog obj using supplierId which is a Foreign key in Catalog Entity and to use the only #OneToOne as every catalog must have one unique supplier

Please help me as I am new to Spring and Hibernate as well in stackoverflow if anything needs to be edited or question is not clear please guide me so I can improve it further.

Thank you for viewing this question now finally I got the answer since I don't know the name of Problem that's why I face this difficult to find the answer. The problem that I was facing is Infinite JSON Recursion Problem, and the solution is to use #JsonManagedReference in the catalogue over supplierId and #JsonBackReference on Supplier over catalog.

cannot insert data to my table in database mysql

i have problem when insert to my database. here my setup for insert to my database.
First, I have method for getExecutionReport
first what i import
import com.dxtr.hibernate.DAOInsert;
import com.dxtr.hibernate.newOrderSingleEntity;
private void getExecutionReport(quickfix.Message message, String tipeMessage) {
// TODO Auto-generated method stub
try {
System.out.print("Message "+ message);
System.out.print("getExecutionReport "+tipeMessage);
newOrderSingleEntity newordersingleObj = new newOrderSingleEntity();
newordersingleObj.setSymbol(message.getString(Symbol.FIELD));
System.out.print(" symbol "+message.getString(Symbol.FIELD));
newordersingleObj.setMsgType(tipeMessage);
System.out.print(" tipeMessage "+tipeMessage);
newordersingleObj.setBodyLength(216);
System.out.print(" Body Length "+216);
newordersingleObj.setFixProtocol("FIX.4.2");
System.out.print("FixProtocol +FIX.4.2");
newordersingleObj.setTransactTime(message.getString(TransactTime.FIELD));
System.out.print(" time " +message.getString(TransactTime.FIELD));
newordersingleObj.setClOrdID(message.getString(ClOrdID.FIELD));
System.out.print(" ClOrdID "+message.getString(ClOrdID.FIELD));
newordersingleObj.setOrderID(message.getString(OrderID.FIELD));
System.out.print(" OrderID "+message.getString(OrderID.FIELD));
newordersingleObj.setExecID(message.getString(ExecID.FIELD));
System.out.print(" ExecID "+message.getString(ExecID.FIELD));
newordersingleObj.setExecTransType(message.getString(ExecTransType.FIELD));
System.out.print(" ExecTransType "+message.getString(ExecTransType.FIELD));
newordersingleObj.setOrdType(message.getString(OrdType.FIELD));
System.out.print(" OrdType "+message.getString(OrdType.FIELD));
newordersingleObj.setExecType(message.getString(ExecType.FIELD));
System.out.print(" ExecType "+message.getString(ExecType.FIELD));
newordersingleObj.setOrdStatus(message.getString(OrdStatus.FIELD));
System.out.print(" OrdStatus "+message.getString(OrdStatus.FIELD));
newordersingleObj.setSide(message.getInt(Side.FIELD));
System.out.print(" Side "+message.getInt(Side.FIELD));
newordersingleObj.setOrderQty(message.getDouble(OrderQty.FIELD));
System.out.print(" OrderQty "+message.getDouble(OrderQty.FIELD));
newordersingleObj.setLeavesQty(message.getDouble(LeavesQty.FIELD));
System.out.print(" LeavesQty "+message.getDouble(LeavesQty.FIELD));
newordersingleObj.setCumQty(message.getDouble(CumQty.FIELD));
System.out.print(" CumQty "+message.getDouble(CumQty.FIELD));
newordersingleObj.setLastShares(message.getInt(LastShares.FIELD));
System.out.print(" LastQty "+message.getInt(LastShares.FIELD));
System.out.print("sebelum insert ke db");
DAOInsert.newOrderSingleInsert(newordersingleObj);
} catch (FieldNotFound e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
this code ok. but when i want to insert to my database my data cannot insert it.

but there is no error in my console print... so where is the problem from my code ?
for information i use mysql5.7 version and using aws
best regards,
Fuad

I would suggest you enable MySQL logs, then follow the instructions at https://dev.mysql.com/doc/refman/5.7/en/server-logs.html and be sure to flush the logs. The logs should be at /bar/log/MySQL

Problems with named queries in Java

I have a problem. I made a dynamic web project using JPA, named queries and a Web Servlet. Here is how the project is organized:
enter image description here
Here are the classes:

Could anyone help me please? Thanks.

Your query
#NamedQuery(name="persona.lista", query="SELECT o from it.ecipar.model.Persona o ORDER by p.cognome, p.nome")
has an error in it. You have Persona o but are then ordering by p.cognome.... You need to use the same table reference so:
#NamedQuery(name="persona.lista", query="SELECT o from it.ecipar.model.Persona o ORDER by o.cognome, o.nome")

One to many mapping with list result illegal Argument exception not a known entity

I am new to JPA. Need to insert data to two databases tables(two tables are different that means no foreign key relationship).I am using POSTMAN to send json data from URL as well as payload body section.

This way of mapping (oneToMany) worked great when I used it for different type... I have no idea what's wrong. I tried few things but they didn't work. I will be grateful for your help!

OneToMany is used to create an association between two entities. java.util.Date is not an entity. It's a basic type. What you want is #ElementCollection.

Try usin #Temporal annotation like this:
#Temporal(value = TemporalType.TIMESTAMP)
#OneToMany(cascade = CascadeType.ALL)
#JoinColumn(name = "time_id")
private List<Date> timetable;

Try Date attribut from java.sql.Date to define each Date attributs of the Time class.
See you.

How to properly use JPA/Hibernate? - java

This makes not much sense. This exception is only thrown when you have a discriminator in the table that has no match in the entity model. Maybe you have trailing spaces in the table?
