Spring Boot 3.5.0 RC1 Release Notes
Thus far, Spring Boot auto-configures a TaskExecutor with the taskExecutor and applicationTaskExecutor bean names.
As of this release, only the applicationTaskExecutor bean name is provided.
Code that is requesting the auto-configured Executor by name should be adapted to use applicationTaskExecutor.
If you relied on this behaviour and cannot change it immediately, the alias can be added using a BeanFactoryPostProcessor, as shown in the following example:
@Configuration
public class MyConfiguration {
@Bean
static BeanFactoryPostProcessor taskExecutorAliasBeanFactoryPostProcessor() {
return (beanFactory) -> beanFactory.registerAlias("applicationTaskExecutor", "taskExecutor");
}
}|
Tip
|
Check the configuration changelog for a complete overview of the changes in configuration. |
If an Executor bean is present, Spring Boot can now be configured to auto-configure an AsyncTaskExecutor anyway.
To do so, set the spring.task.execution.mode property to force.
When running in this mode, it makes sure that all integrations, including regular @Async processing uses the auto-configured executor,
unless an AsyncConfigurer bean is defined.
As an annotation-based alternative to ServletRegistrationBean and FilterRegistrationBean two new annotations have been added.
@ServletRegistration can be used to register Servlet`s, while `@FilterRegistration can be used to register `Filter`s, as shown in this example:
@Configuration(proxyBeanMethods = false)
class MyConfiguration {
@Bean
@FilterRegistration(name = "my-filter", urlPatterns = "/test/*", order = 0)
MyFilter myFilter() {
return new MyFilter();
}
}
