BasicDataSource's method close() doesn't deregister JDBC driver. This causes permgen memory leaks in web server environments, during context reloads. For example, using Tomcat 6.0.26 with Spring, and BasicDataSource declared in Spring context, there is a message printed at web application reload:

The basic properties is the driver classname, connection url, username and password. This example demonstrate how to use the BasicDataSource class of Apache Commons DBCP to create a basic requirements for database connection. In the Java example code for connection pooling using Apache DBCP there are two Java classes. We have a PooledDataSource class with a static block to create an instance of DBCP's BasicDataSource. There is another class DSConnection where we get the instance of dbcp2 BasicDataSource and use it to get the Connection object. It is the responsibility of different Database vendors to provide different kinds of implementation of DataSource interface.

Even Hibernate doesn’t come with connection provider like C3P0 and Proxool, but you still can configure it easily.. In this tutorial, we show you how to integrate … JNDI object factory that creates an instance of BasicDataSource that has been configured based on the RefAddr values of the specified Reference, which must match the names and data types of the BasicDataSource bean properties with the following exceptions: connectionInitSqls must be passed to this factory as a single String using semicolon to delimit the statements whereas BasicDataSource The BasicDataSource url property in your Spring config should not be the path to your jar.

Spring Hibernate; 55.

Spring Boot uses an opinionated algorithm to scan for and configure a DataSource.This allows us to easily get a fully-configured DataSource implementation by default.. In addition, Spring Boot automatically configures a lightning-fast connection pool — either HikariCP, Apache Tomcat, or Commons DBCP, in that order, depending on which are on the classpath.

In the example DB used is MySQL it connects to knpcode schema and table is EMPLOYEE with columns as id, FIRST_NAME, LAST_NAME and DEPARTMENT. Apache DBCP provides a BasicDataSource class which creates a PoolingDataSource. Steps for creating a DataSource instance using BasicDataSource and configuring connection pool are as follows-1. For example, maxTotal=20 and 18 active connections and 1 idle connection would trigger removeAbandonedOnBorrow, but only the active connections that aren't used for more then "removeAbandonedTimeout" seconds are removed (default 300 sec). Traversing a … 2018-08-05 That's all for this topic Connection Pooling With Apache DBCP Spring Example. If you have any doubt or any suggestions to make please drop a comment. Thanks!

So, I don't think you need to use synchronize block. If you are extending this class you should just take care to use appropriate accessors,rather than accessing protected fields directly to ensure thread-safety, but you don't need to use synchronize blocks. – ivi Jan 22 '13 at 23:43 // In this example, we'll construct the BasicDataSource manually, // but you could also configure it using an external conifguration file. // // // Note that this example is very similiar to the PoolingDriver // example.

DBCP Connection Pooling Example exaplains about how to create and configure a Connection pool using DBCP Datasource. Many Apache projects support interaction with a relational database, DBCP one among them. In the example DB used is MySQL it connects to knpcode schema and table is EMPLOYEE with columns as id, FIRST_NAME, LAST_NAME and DEPARTMENT.

For example MySQL JDBC Driver provides basic implementation of DataSource interface with com.mysql.jdbc.jdbc2.optional.MysqlDataSource class and Oracle database driver implements it with oracle.jdbc.pool.OracleDataSource class. These implementation classes provide methods through which we can provide database server details with user credentials.

let dataSource = BasicBlockDataSource < Example, BasicTableViewCell > { (item: Example, cell: BasicTableViewCell, indexPath) -> Void in cell. titleLabel?. text = item. title} // Need to keep a strong reference to our data source. self. dataSource = dataSource // register the cell tableView. ds_register (cellClass: BasicTableViewCell. self) // bind the data source to the table view tableView. ds_useDataSource (dataSource) dataSource. items = << retrieve items >> // Can be set and altered at

// In this example, we'll construct the BasicDataSource manually, // but you could also configure it using an external conifguration file. DataSource object increases the application portability.
