测试Druid数据库连接池
package connection;
import java.io.IOException;
import java.io.InputStream;
import java.sql.Connection;
import java.util.Properties;
import javax.sql.DataSource;
import org.junit.Test;
import com.alibaba.druid.pool.DruidDataSource;
import com.alibaba.druid.pool.DruidDataSourceFactory;
public class DruidTest {
@Test
public void getConnection() throws Exception {
Properties pros = new Properties();
InputStream is = ClassLoader.getSystemClassLoader().getResourceAsStream("druid.properties");
pros.load(is);
DataSource source = DruidDataSourceFactory.createDataSource(pros);
Connection conn = source.getConnection();
System.out.println(conn);
}
}
直接调用方法
//使用Druid数据库连接池技术来获取数据库连接
private static DataSource source1;
static {
try {
Properties pros = new Properties();
InputStream is = ClassLoader.getSystemClassLoader().getResourceAsStream("druid.properties");
pros.load(is);
source1 = DruidDataSourceFactory.createDataSource(pros);
} catch (Exception e) {
e.printStackTrace();
}
}
public static Connection getConnection3() throws Exception {
Connection conn = source1.getConnection();
return conn;
}
