Druid（德鲁伊）数据库连接池

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;
    }
