Class AbstractColumnMaxValueIncrementer

java.lang.Object

org.springframework.jdbc.support.incrementer.AbstractDataFieldMaxValueIncrementer

org.springframework.jdbc.support.incrementer.AbstractColumnMaxValueIncrementer

All Implemented Interfaces:

InitializingBean, DataFieldMaxValueIncrementer

Direct Known Subclasses:

AbstractIdentityColumnMaxValueIncrementer, MySQLMaxValueIncrementer, SqliteMaxValueIncrementer

public abstract class AbstractColumnMaxValueIncrementer
extends AbstractDataFieldMaxValueIncrementer

Abstract base class for DataFieldMaxValueIncrementer implementations that use a column in a custom sequence table. Subclasses need to provide the specific handling of that table in their AbstractDataFieldMaxValueIncrementer.getNextKey() implementation.

Since:

2.5.3

AbstractColumnMaxValueIncrementer

public AbstractColumnMaxValueIncrementer(DataSource dataSource,
 String incrementerName,
 String columnName)

Convenience constructor.

Parameters:

dataSource - the DataSource to use

incrementerName - the name of the sequence/table to use

columnName - the name of the column in the sequence table to use

Method Details

setColumnName

public void setColumnName(@Nullable String columnName)

Set the name of the column in the sequence table.

getColumnName

public @Nullable String getColumnName()

Return the name of the column in the sequence table.

setCacheSize

public void setCacheSize(int cacheSize)

Set the number of buffered keys.

getCacheSize

public int getCacheSize()

Return the number of buffered keys.

afterPropertiesSet

public void afterPropertiesSet()

Description copied from interface: InitializingBean

Invoked by the containing BeanFactory after it has set all bean properties and satisfied BeanFactoryAware, ApplicationContextAware etc.

This method allows the bean instance to perform validation of its overall configuration and final initialization when all bean properties have been set.
