Class TaskExecutorBatchConfigurer

java.lang.Object

de.codecentric.batch.configuration.TaskExecutorBatchConfigurer

All Implemented Interfaces:

org.springframework.batch.core.configuration.annotation.BatchConfigurer

@ConditionalOnMissingBean(value=org.springframework.batch.core.configuration.annotation.BatchConfigurer.class)
@Configuration
public class TaskExecutorBatchConfigurer
extends Object
implements org.springframework.batch.core.configuration.annotation.BatchConfigurer

This batch infrastructure configuration is quite similar to the DefaultBatchConfigurer, it only introduces a TaskExecutor used in the SimpleJobLauncher for starting jobs asynchronously. Its thread pool is configured to four threads by default, which can be changed by setting the property batch.max.pool.size to a different number. The TaskExecutor may also be used in job configurations for multi-threaded job execution. In XML you can use it by name, which is taskExecutor. In JavaConfig, you can either autowire TaskExecutor or, if you want to know where it's configured, this class.
