Java – JPA: @ primarykeyjoincolumn (…) and @ joincolumn (…, insertable =?, updatable =?) Same?

• Java

It can be derived from the JPA specification if there is no @ primarykeyjoincolumn (...) with pluggable and updatable parameters

@JoinColumn(...,insertable = false,updatable = false)

or

@JoinColumn(…,insertable = true,updatable = true)

For general (non inherited) associations? Should I swap? What are pluggable and updatable properties set to? Did they set anything? Note that I only navigate to (seemingly) implemented read-only properties

I'm using eclipse link and hibernate to get very inconsistent mapping exceptions

This is @ primarykeyjoincolumn JavaEE 5 6 Javadoc:

PrimaryKeyJoinColumn (JavaEE 5) PrimaryKeyJoinColumn (JavaEE 6)

quote:

Solution

Yes, they are equivalent

Note that in JPA 2.0, you can also add @ ID to the @ onetoone map and avoid duplicate base ID attributes that are exactly the same

notice

>Identity and sequencing > primary keys through onetoone and manytoone relationships and > onetoone > target foreign keys, primary key join columns, cascade primary keys
