How to retrieve DB connection using DataSource without JNDI?

问题

We want our own db connection configuration instead of using JNDI, but in the meantime, we also want to use DataSource instead of using DriverManager, how to do so?

回答1:

You use a connection pool library like c3p0 or commons dbcp.

C3P0

ComboPooledDataSource cpds = new ComboPooledDataSource();
cpds.setDriverClass( "org.postgresql.Driver" ); //loads the jdbc driver            
cpds.setJdbcUrl( "jdbc:postgresql://localhost/testdb" );
cpds.setUser("dbuser");                                  
cpds.setPassword("dbpassword");

Connection connection = cpds.getConnection();

DBCP

BasicDataSource ds= new BasicDataSource();
ds.setDriverClassName("org.postgresql.Driver");
ds.setUrl("jdbc:postgresql://localhost/testdb");
ds.setUsername("dbuser");
ds.setPassword("dbpassword");

Connection connection = ds.getConnection();

回答2:

You can use org.apache.commons.dbcp.BasicDataSource

BasicDataSource ds= new BasicDataSource();
ds.setDriverClassName("oracle.jdbc.driver.OracleDriver");
ds.setUrl("jdbc:oracle:thin:@dburl:port:sid");
ds.setUsername("uname");
ds.setPassword("pass");
