- org.springframework.boot.task.TaskSchedulerBuilder

```
public class TaskSchedulerBuilder
extends Object
```
Builder that can be used to configure and create a TaskScheduler. Provides convenience methods to set common ThreadPoolTaskScheduler settings. For advanced configuration, consider using TaskSchedulerCustomizer.
In a typical auto-configured Spring Boot application this builder is available as a bean and can be injected whenever a TaskScheduler is needed.
Since:
2.1.0

  - poolSize
```
public TaskSchedulerBuilder poolSize(int poolSize)
```
    Set the maximum allowed number of threads.
    Parameters:
    poolSize - the pool size to set
    Returns:
    a new builder instance
  - threadNamePrefix
```
public TaskSchedulerBuilder threadNamePrefix(String threadNamePrefix)
```
    Set the prefix to use for the names of newly created threads.
    Parameters:
    threadNamePrefix - the thread name prefix to set
    Returns:
    a new builder instance
  - customizers
```
public TaskSchedulerBuilder customizers(TaskSchedulerCustomizer... customizers)
```
    Set the TaskSchedulerCustomizers that should be applied to the ThreadPoolTaskScheduler. Customizers are applied in the order that they were added after builder configuration has been applied. Setting this value will replace any previously configured customizers.
    Parameters:
    customizers - the customizers to set
    Returns:
    a new builder instance

public TaskSchedulerBuilder additionalCustomizers(TaskSchedulerCustomizer... customizers)
```
    Add taskSchedulerCustomizers that should be applied to the ThreadPoolTaskScheduler. Customizers are applied in the order that they were added after builder configuration has been applied.
    Parameters:
    customizers - the customizers to add
    Returns:
    a new builder instance

```
public TaskSchedulerBuilder additionalCustomizers(Iterable<TaskSchedulerCustomizer> customizers)
```
    Add taskSchedulerCustomizers that should be applied to the ThreadPoolTaskScheduler. Customizers are applied in the order that they were added after builder configuration has been applied.
    Parameters:
    customizers - the customizers to add
    Returns:
