driver should include at least a basic DataSource implementation. For example , the Java DB JDBC driver includes the implementation org.apache.derby.jdbc.

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

Step.1 Start a Web based Spring application Select New menu -> Dynamic Web Project 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. 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. That's all for this topic Connection Pooling With Apache DBCP Spring Example.

The BasicDataSource url property in your Spring config should not be the path to your jar. See some examples of working Spring configs here.

// 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.

Traversing a resultset doesn't count as being used. 2013-12-24 · Different Connection Pool Implementation examples. 1) DBCP Connection Pooling Example 2) C3P0 Connection Pooling Example 3) BoneCP Connection Pooling Example 4) H2 Database Connection Pool Example Required Libraries DataSource object increases the application portability. An example given below is an example of BasicDataSourse example.

BasicDataSource is thread-safe, because all variables are read/written via synchronised. 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

BasicDataSource dataSource = new BasicDataSource (); dataSource. setDriverClassName (getDriverClassName()); dataSource. setUrl (getJDBCUrl(params)); dataSource. setUsername (user); dataSource. setPassword (passwd); dataSource.

Inline expression identifier can use ${} or $->{}, but ${} is conflict with spring placeholder of properties, so use $->{} on 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.
