JdbcEntityWriter and JdbcDeleteEntityWriter now use an iterative approach based on PersistentPropertyPath instead of a recursive one.
DbAction is now split into multiple interfaces representing different variants of actions.
The implementations are simple value types without any implementation inheritance hierarchy.
All elements of a DbAction implementation are not null making usage and construction of instances much easier.

We now support configurable conversion by introducing CustomConversions and RelationalConverter. CustomConversions is a registry for converters that should be applied on a per-type basis for properties. CustomConversions is typically registered as bean and fed into RelationalMappingContext and the newly introduced RelationalConverter to consider simple types and conversion rules.
RelationalConverter with its implementation BasicRelationalConverter encapsulates conversion infrastructure such as EntityInstantiator, CustomConversions, and MappingContext that is required during relational value conversion. BasicRelationalConverter is responsible for simple value conversion and entity instantiation to pull related code together. It's not in full charge of row result to object mapping as this responsibility remains as part of DataAccessStrategy.
This change supersedes and removes ConversionCustomizer.
We now treat all properties of an entity mutable and continue to use the reflective PersistentPropertyAccessor implementation to make sure we don't break the old behavior of reflectively mutating immutable objects.
This is a workaround for now and has to be replaced by more exhaustive changes later.

All packages now use @NoNullApi.
All warnings related to that fixed, except a few cases where upstream annotations are simply wrong.
Added null checks.
Fixed generic types where possible.
Improved Javadoc.
Code Formatting.
Replaced the direct use of EntityInstantiator with EntityInstantiators.
Moved it into the MappingContext because instantiation is part of the mapping process.

Edited for spelling, punctuation, grammar, usage, and corporate voice.
Also added an epub cover image and the SVG file from which it can be generated.

Moved to both the usage of the newly introduced PersistentEntity.isNew(…) and identifier lookups via PersistentEntity instead of using a custom EntityInformation implementation. JdbcRepositoryFactory now creates a PersistentEntityInformation, SimpleJdbcRepository simply works with a PersistentEntity.
Removed references to EntityInformation (a repository subsystem concept) from the template implementation. Removed BasicJdbcPersistentEntity and its tests entirely. JdbcAuditingEventListener is now using an IsNewAwareAuditingHandler.

Moved the implementation from the DelimiterNamingStrategy into the NamingStrategy.
Dropped the support for different separators, since there is no good way to support it in the default implementations of an interface.
A getSeparator() method would bleed into the public API.
Also the added value of that flexibility seems limited.
During migration of the various test it became obvious that SqlGeneratorUnitTests was broken since test failures happend on a worker thread not on the main test thread.
This is fixed as well with this commit.
Such a parameter would only make sense with inheritance and we don't support inheritance at all in the moment.
Anything we need in order to support inheritance should be added once we do support inheritance.
The existing test only analysed Spring Data JDBC itself.
The new test also considers packages from commons and treats
org.springframework.data.x.X
and
org.springframework.data.jdbc.x.Y
as belonging to the same "sub-module" "x".
Moved the dependency to NamedParameterJdbcOperations out of JdbcMappingContext. This revealed that despite the DataAccessStrategy abstraction, there are a couple of places in the query execution subsystem that work with a plain NamedParameterJdbcOperations instance, so that we now have to carry that around all the way from the repository factory bean. Improving that is subject for further changes.
A bit of JavaDoc and generics polish here and there.
Moved annotation processing of @Table and @Column into metamodel classes so that the NamingStrategy is only responsible for generic fallbacks. Allow @Column to be used as meta-annotation.
Simplified code by using constructor injection plus Lombok.
Removed superfluous handling of BeforeSave events with null entity.

Since Timestamp extends Date the repository returns the Timestamp as it comes from the database.
Trying to compare that to an actual Date results in non determistic results, so we have to use an actual Timestamp.
Original pull request: #66.
Set logging level to WARN.
Removed a System.out call.
The detail loggers are still in the logback.xml as comments to be used for debugging and demonstration purposes.
Extracted ApplicationContext and Repository construction into method in order to make the actual test stand out more.
Split a test in two.
JavaDoc.
Code formatting.
Removed access modifiers in tests.
When enabled by using @EnableJdbcAuditing entities will get properties annotated with
* @CreatedBy
* @CreatedDate
* @LastModifiedBy
* @LastModifiedDate
updated when saved.
