@OneToMany : Mapping hibernate data is getting inserted in child table while updating parent table

Why in “One to Many” Mapping hibernate data is getting inserted in child table while updating parent table ?

Solution :

You are using cascade = CascadeType.ALL in both @OneToMany mappings of your Sets.

This means that whatever operation done on the parent entity, will be propagate also to the child entity

That is when you

• PERSIST
• REFRESH
• MERGE
• REMOVE
• DETACH

the same would be applied to these children.

If you only want to cascade when the parent entity is

• PERSISTED (or saved in the hibernate language)
• DELETED (two most common options for @OneToMany)

, but during MERGE and subsequent update, you do not want to cascade those operations to children then set-up you mappings as follows:

@OneToMany(fetch=FetchType.EAGER, mappedBy="billInformation"
          , cascade = { CascadeType.PERSIST, CascadeType.REMOVE }
          ,orphanRemoval=true)
Set<BillingItemInformation> setBillingItemInformation;

@OneToMany(fetch=FetchType.EAGER, mappedBy="billInformation"
         , cascade ={ CascadeType.PERSIST, CascadeType.REMOVE }
         ,orphanRemoval=true)
Set<BillingTaxInformation> setBillingTaxInformation;

Update

With hibernate annotation you would configure as follows:

@Cascade({CascadeType.PERSIST, CascadeType.DELETE})
