This commit replaces synchronized blocks and methods
that are used frequently or that guard blocking I/O
operations with locks. This is required to prevent
virtual threads pinning, as explained in JEP 444 [1].
Note that synchronized blocks and methods that are used
infrequently (like AutomaticJobRegistrar#start/stop) or
that guard in-memory operations were not replaced as this
is not required, see JEP 444 [1].

Consistently use Assert.state in the afterPropertiesSet()
methods to throw IllegalStateException instead of
IllegalArgumentException when some properties are missing
and/or invalid.

Before this commit, the user had to manually set the job repository and transaction
manager on `JobBuilder` and `StepBuilder` instances with a chained call to
`.repository(jobRepository)` and `.transactionManager(transactionManager)`.
This is error prone and can lead to runtime errors if these properties are not set.
This commit introduces new APIs to guide the user to set these properties at
builder creation time.
Resolves#4192
This commit deprecates JobBuilderFactory and StepBuilderFactory
in favor of the respective builders they create.
It also removes the exposure of such utilities as beans in the
application context when using `@EnableBatchProcessing`.
Resolves https://github.com/spring-projects/spring-batch/issues/4188
Before this commit, the transaction manager was configurable
at the StepBuilder level, which is inconsistent with the XML
config style in addition to be not needed for most step types.
This commit moves the configuration of the transaction manager
from the StepBuilder down to the AbstractTaskletStepBuilder,
which is the level where the transaction manager is needed.
Resolves#4130
This commit replaces the usage of List with Chunk
where appropriate. Summary of changes:
- The Chunk class was moved from the `org.springframework.batch.core.step.item` package to the `org.springframework.batch.item` package
- The signature of the method `ItemWriter#write(List)` was changed to `ItemWriter#write(Chunk)`
- All implementations of `ItemWriter` were updated to use the Chunk API instead of List
- All methods in the `ItemWriteListener` interface were updated to use the Chunk API instead of List
- All implementations of `ItemWriteListener` were updated to use the Chunk API instead of List
- The constructor of `ChunkRequest` was changed to accept a Chunk instead of a Collection of items
- The return type of `ChunkRequest#getItems()` was changed from List to Chunk
Resolves#3954
This commits changes the type of the transaction manager
from `DataSourceTransactionManager` to `JdbcTransactionManager`
in the default configuration of `@EnableBatchProcessing`.
The `JdbcTransactionManager` adds common JDBC exception translation
which is beneficial for Spring Batch to improve exception handling
and error reporting.
Resolves#4126
This commit adds SAP HANA as a supported Spring Batch database, enabling
developers to seamlessly move their existing Spring Batch projects to SAP HANA
or easily starting new Spring Batch projects on SAP HANA.
This commit contains the following changes:
- Add SAP HANA to the DatabaseType enum
- Add HanaPagingQueryProvider and tests
- Add properties files for SAP HANA
Issue #2515
Due to the decoupling of `PagingAndSortingRepository` from
`CrudRepository` in Spring Data 3 [1], this test has to be updated
to use different repositories between the reader and the writer
according to the expected types for the `repository` property.

This commit removes the unconditional exposure of the transaction
manager as a bean in the application context. The transaction manager
is still taken from the BatchConfigurer and set where needed (ie on
JobRepository and StepBuilderFactory) as previously done,
but is not exposed anymore as a bean to prevent any clash with a user
defined transaction manager.
If no transaction manager is provided, a DataSourceTransactionManager
will be configured by default as required by batch (without being exposed
as a bean).
