Batch (hibernate-jdk11 5.4.12.Final API)

所有已知实现类:

AbstractBatchImpl, BatchingBatch, NonBatchingBatch
```
public interface Batch
```
Conceptually models a batch.
Unlike directly in JDBC, here we add the ability to batch together multiple statements at a time. In the underlying JDBC this correlates to multiple PreparedStatement objects (one for each DML string) maintained within the batch.

修饰符和类型	方法	说明
`void`	`addObserver(BatchObserver observer)`	Adds an observer to this batch.
`void`	`addToBatch()`	Indicates completion of the current part of the batch.
`void`	`execute()`	Execute this batch.
`PreparedStatement`	`getBatchStatement(String sql, boolean callable)`	Get a statement which is part of the batch, creating if necessary (and storing for next time).
`BatchKey`	`getKey()`	Retrieves the object being used to key (uniquely identify) this batch.
`void`	`release()`	Used to indicate that the batch instance is no longer needed and that, therefore, it can release its resources.
