This example demonstrates how to use the BasicDataSource class of Apache Commons DBCP to create a basic requirements for database connection. The configuration of the data source can be defined using some properties method provided by this class. The basic properties is the driver classname, connection url, username and password.

The Spring MySQL application context file. Here's the source code for the Spring MySQL application context file (which I named applicationContext.xml): 2019-07-24 2013-12-24 The following examples show how to use org.apache.commons.dbcp.BasicDataSource.These examples are extracted from open source projects. You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the links above each example. 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.

Basicdatasource example

setPassword (passwd); dataSource. setMaxWait (maxWait * 1000); dataSource. setMinIdle (minConn); dataSource. setMaxActive (maxConn); dataSource. setTestOnBorrow (true); dataSource. setValidationQuery (getValidationQuery()); dataSource.

In the below example, I show you how to get a database connection. Once the connection is established, the example, executes few statements. It creates a database table, inserts data and queries the inserted data. To make sure we can run this example more than once, I drop the table before the issue of ‘create table’ statement.

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. 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 resultset doesn't count as being used.

BasicDataSource If you want to use Spring Java Configuration then you can create an object of BasicDataSource and set the properties. @Bean public BasicDataSource basicDataSource(){ BasicDataSource ds = new BasicDataSource(); ds.setDriverClassName("com.mysql.jdbc.Driver"); ds.setUrl("jdbc:mysql://localhost:3306/netjs"); .. .. return ds; } BasicDataSource ds = new BasicDataSource(); ds.setDriverClassName("oracle.jdbc.driver.OracleDriver"); ds.setUsername("scott"); ds.setPassword("tiger"); ds.setUrl(connectURI); Then you get your DB connections through the getConnection() method.

It is the responsibility of different Database vendors to provide different kinds of implementation of DataSource interface.

setMaxActive (maxConn); dataSource. setTestOnBorrow (true); dataSource. setValidationQuery (getValidationQuery()); dataSource.

In this example, we shall show you how to use BasicDataSource of Apache commons dbcp library. DBCP is a part of apache common components and intended for database connection pooling. BasicDataSource is a basic implementation of javax.sql.DataSource. Using BasicDataSource, one can easily connect to a Relational Database as we will show in following example.

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. import org.apache.commons.dbcp2.BasicDataSource; // Here's a simple example of how to use the BasicDataSource. // Note that this example is very similar to the PoolingDriver 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.
