Java如何动态生成BasicDataSource数据源

public static BasicDataSource newDataSource(String url, String username, String password) {
BasicDataSource newDataSource = new BasicDataSource();

newDataSource.setInitialSize(2);
newDataSource.setMaxActive(10);
newDataSource.setMaxIdle(2);
newDataSource.setMaxWait(500);
newDataSource.setValidationQuery("select 1 from dual");

//根据url提取出数据库类型
String[] strArray = url.trim().split(":");
String dbType = strArray[1];
if (dbType.equalsIgnoreCase("oracle")) {
newDataSource.setDriverClassName("oracle.jdbc.driver.OracleDriver");
}
else if (dbType.equalsIgnoreCase("mysql")) {
newDataSource.setDriverClassName("com.mysql.jdbc.Driver");
}

newDataSource.setUrl(url);
newDataSource.setUsername(username);
newDataSource.setPassword(password);

return newDataSource;

}
