Constructor Detail

### BeanFactoryDataSourceLookup

    public BeanFactoryDataSourceLookup()

  Create a new instance of the `BeanFactoryDataSourceLookup` class.

  The BeanFactory to access must be set via `setBeanFactory`.

  See Also:
    `setBeanFactory(org.springframework.beans.factory.BeanFactory)`

### BeanFactoryDataSourceLookup

    public BeanFactoryDataSourceLookup(BeanFactory beanFactory)

  Create a new instance of the `BeanFactoryDataSourceLookup` class.

  Use of this constructor is redundant if this object is being created by a Spring IoC container, as the supplied `BeanFactory` will be replaced by the `BeanFactory` that creates it (c.f. the `BeanFactoryAware` contract). So only use this constructor if you are using this class outside the context of a Spring IoC container.

  Parameters:
    `beanFactory` - the bean factory to be used to lookup `DataSources`

Method Detail

### setBeanFactory

    public void setBeanFactory(BeanFactory beanFactory)

  Description copied from interface: `BeanFactoryAware`
  Callback that supplies the owning factory to a bean instance.

  Invoked after the population of normal bean properties but before an initialization callback such as `InitializingBean.afterPropertiesSet()` or a custom init-method.

  Specified by:
    `setBeanFactory` in interface `BeanFactoryAware`
  Parameters:
    `beanFactory` - owning BeanFactory (never `null`). The bean can immediately call methods on the factory.
  See Also:
    `BeanInitializationException`

### getDataSource

    public DataSource getDataSource(String dataSourceName)
                             throws DataSourceLookupFailureException

  Description copied from interface: `DataSourceLookup`
  Retrieve the DataSource identified by the given name.

  Specified by:
    `getDataSource` in interface `DataSourceLookup`
  Parameters:
    `dataSourceName` - the name of the DataSource
  Returns:
    the DataSource (never `null`)
  Throws:
    `DataSourceLookupFailureException` - if the lookup failed
