Class DynamicDataSourceProxy

java.lang.Object

org.springframework.jdbc.datasource.DelegatingDataSource

com.jolbox.bonecp.spring.DynamicDataSourceProxy

All Implemented Interfaces:

Wrapper, CommonDataSource, DataSource, org.springframework.beans.factory.InitializingBean

public class DynamicDataSourceProxy
extends org.springframework.jdbc.datasource.DelegatingDataSource

Like a normal datasource except it supports an extra method: switchDataSource to slowly migrate to a new datasource. Simply call switchDataSource with your new BoneCP configuration: the existing pool will be shutdown gracefully (checkout out connections are unaffected) and a new one will take it's place. A typical use case would be to transparently instruct your application to use a new database without restarting the application.
