IdentifierGenerator (hibernate-jdk11 5.4.12.Final API)

所有已知子接口:

BulkInsertionCapableIdentifierGenerator, PersistentIdentifierGenerator, PostInsertIdentifierGenerator

所有已知实现类:

AbstractPostInsertGenerator, AbstractUUIDGenerator, Assigned, CompositeNestedGeneratedValueGenerator, ForeignGenerator, GUIDGenerator, IdentityGenerator, IncrementGenerator, MultipleHiLoPerTableGenerator, SelectGenerator, SequenceGenerator, SequenceHiLoGenerator, SequenceIdentityGenerator, SequenceStyleGenerator, TableGenerator, UUIDGenerator, UUIDHexGenerator
```
public interface IdentifierGenerator
```
The general contract between a class that generates unique identifiers and the Session. It is not intended that this interface ever be exposed to the application. It is intended that users implement this interface to provide custom identifier generation strategies.

Implementors should provide a public default constructor.

Implementations that accept configuration parameters should also implement Configurable.
Implementors must be thread-safe

    Generate a new identifier.
    
    参数:
    
    session - The session from which the request originates
    
    object - the entity or collection (idbag) for which the id is being generated
    
    返回:
    
    a new identifier
    
    抛出:
    
    HibernateException - Indicates trouble generating the identifier
  - supportsJdbcBatchInserts
