Location and UseCase for AggregateItemReader

Question

Appendix Here lists a reader AggregateItemReader but I am not able to find it in any of Spring Batch jar files. I am using spring batch with spring boot and have version 3.0.7.

API Doc indicates it in samples package.

Currently, I am using JdbcPagingItemReader in my project but I want reader to return a List or Collection of objects to processor instead of a single object.This is needed so I can process those objects in bulk instead of processing one by one.

Pagination requirement is mandatory so I use JdbcPagingItemReader

By reading description, it looks AggregateItemReader was the candidate but can't find its implementation.

Any Ideas? Are there any alternatives?

The package org.springframework.batch.sample.domain.multiline containing AggregateItemReader class seems to be in the spring-batch-samples artifact; this should be also imported into your project separately from spring-batch-core. E.g. in maven pom.xml the following dependency resolves the issue

<dependency>
  <groupId>org.springframework.batch</groupId>
  <artifactId>spring-batch-samples</artifactId>
  <version>3.0.0.M3</version>
</dependency>

is it OK to use something from Spring samples for a production application? – Sabir Khan Oct 05 '16 at 03:35
You should probably clarify that with your employer/customer – hammerfest Oct 05 '16 at 09:43

I simply used that reader as reference to write my own similar reader but I feel pivotal should specify that in their docs if some of their code is production ready or not. – Sabir Khan Mar 23 '18 at 08:24
