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
