public interface ItemWriter<T>
Basic interface for generic output operations. Class implementing this interface will be responsible for serializing objects as necessary. Generally, it is responsibility of implementing class to decide which technology to use for mapping and how it should be configured.
The write method is responsible for making sure that any internal buffers are flushed. If a transaction is active it will also usually be necessary to discard the output on a subsequent rollback. The resource to which the writer is sending data should normally be able to handle this itself.
void write(java.util.List<? extends T> items) throws java.lang.Exception
java.lang.Exception- if there are errors. The framework will catch the exception and convert or rethrow it as appropriate.
