java hibernate one to many "Hibernate mapping files and POJOs from database"

Question

I'm using Hibernates "Hibernate mapping files and POJOs from database" to transform tables to POJOs. The problem is that the table relations do not automatically create a "Set ..." property. What do I have to do to make Hibernate work with this?

Example table structure:

Edit: So for example Stock has a property "Set StockDailyRecord". Hibernate should add them automatically. An example of what I mean can be found here: http://www.tutorialspoint.com/hibernate/hibernate_set_mapping.htm

Answer 1

It's the job of the developer to create the setters and getters for the java objects.

Assuming you have a field

private Set<Stock> stockDailyRecord;

Normally you would create a pair:

public Set<Stock> getStockDailyRecord();
public void setStockDailyRecord( Set<Stock> newRecordSet);

And then you would also normally create a convenience method

public void addDailyRecord( Stock newRecord)
{
    this.getStockDailyRecord().add(newRecord);
}

Hint: most IDEs will create the getter/setters for you after you define the fields.

Answer 2

Typically, you only need a getter for relations.

  Set<StockDailyRecord> getStockDailyRecords() { return stockDailyRecords; }

and then

  StockDailyRecord aStockDailyRecord = ...
  stock.getStockDailyRecords().add(aStockDailyRecord);
