Class IbatisBatchItemWriter<T>

java.lang.Object

org.springframework.batch.item.database.IbatisBatchItemWriter<T>

All Implemented Interfaces:

ItemWriter<T>, org.springframework.beans.factory.InitializingBean

public class IbatisBatchItemWriter<T>
extends Object
implements ItemWriter<T>, org.springframework.beans.factory.InitializingBean

ItemWriter that uses the batching features from SqlMapClientTemplate to execute a batch of statements for all items provided.
The user must provide an iBATIS statement id that points to the SQL statement defined in the iBATIS SqlMap configuration.
It is expected that write(List) is called inside a transaction.
The writer is thread safe after its properties are set (normal singleton behavior), so it can be used to write in multiple concurrent transactions.

Since:

2.0
