The SimpleAsyncTaskExecutorBuilder can be used to create
SimpleAsyncTaskExecutor. It will be auto-configured into the context.
SimpleAsyncTaskExecutorCustomizer can be used to customize the built
SimpleAsyncTaskExecutor.
If virtual threads are enabled:
- SimpleAsyncTaskExecutor will use virtual threads
- SimpleAsyncTaskExecutorBuilder will be used as the application task
executor
A new property 'spring.task.execution.simple.concurrency-limit' has been
added to control the concurrency limit of the SimpleAsyncTaskExecutor
Closes gh-35711
The new ConnectionFactoryDecorator can be used to decorate the
ConnectionFactory built by the ConnectionFactoryBuilder.
The new R2dbcObservationAutoConfiguration configures a
ConnectionFactoryDecorator to attach a ObservationProxyExecutionListener
to ConnectionFactories. This enables Micrometer Observations for R2DBC
queries.
Closes gh-33768
When there is an existing value, deducing the bind method may
incorrectly result in the use of constructor binding. This
results in a failure in the configuration properties
post-processor as it refuses to bind properties to a bean whose
attributes indicate that constructor binding should have been used.
This commit updates ConfigurationPropertiesBean to avoid tryin to
deduce the bind method and instead use the presence or absence of an
existing value to determine the type of binding that should be used.
Only when there is no existing value is constructor binding
appropriate.
Fixes gh-36175
Previously, with the converter beans in a conversion service that
appears after the bean factory's conversion service, they would not
be called for a conversion that could be handled by the
ObjectToObjectConverter in the bean factory's conversion service.
This commit creates a new FormattingConversionService that is empty
except for the converter beans and places it first in the list.
It's followed by the bean factory's conversion service. The shared
application conversion service is added to the end of the list to
pick up any conversions that the previous two services could not
handle. This should maintain backwards compatibility with the
previous arrangement where the converter beans were added to an
application conversion service that went after the bean factory's
conversion service.
Fixes gh-34631
