Commons DBCP for Connection Pooling
This section provides a quick introduction on Commons DBCP, which is a popular open source JDBC database connection pool library developed by Apache.
Commons DBCP is a popular open source JDBC database connection pool library developed by Apache. Here is what I did to download Commons DBCP on my local computer.
1. Go to Commons DBCP Website at https://commons.apache.org/proper/commons-dbcp.
2. Click "Downloads" link and download "commons-dbcp2-2.8.0-bin.zip".
3. Unzip the download file to get the JAR file:
commons-dbcp2-2.8.0/ 207774 Jan 22 2020 commons-dbcp2-2.8.0.jar
According to the documentation, we have 3 options to create a connection pool with Commons DBCP:
1. Using org.apache.commons.dbcp2.BasicDataSource class, which implements the standard JDBC javax.sql.DataSource interface to manage the connection pool with JavaBean style properties.
2. Using org.apache.commons.dbcp2.PoolingDataSource class, which implements the standard JDBC javax.sql.DataSource interface to manage the connection pool with a manually created object pool.
3. Using org.apache.commons.dbcp2.PoolingDriver class, which implements the standard JDBC javax.sql.Driver interface to manage the connection pool with a custom JDBC driver.
To use Commons DBCP 2.8.0, you also need to download 2 more Apache Java packages:
