web项目，利用Druid创建JDBCUtil

1.

package com.cuc.utils;

import com.alibaba.druid.pool.DruidDataSourceFactory;

import javax.sql.DataSource;
import java.io.InputStream;
import java.sql.Connection;
import java.sql.SQLException;
import java.util.Properties;

public class JDBCUtil {
    private static DataSource ds;

    static {
        try {
            //获取配置路径
            InputStream is = JDBCUtil.class.getClassLoader().getResourceAsStream("druid.properties");
            //加载配置文件
            Properties pro = new Properties();
            pro.load(is);
            //初始化连接对象
            ds = DruidDataSourceFactory.createDataSource(pro);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    /**
     * 获取连接对象
     */
    public static DataSource getDataSource() {
        return ds;
    }

    /**
     * 获取连接池
     */
    public static Connection getConnection() throws SQLException {
        return ds.getConnection();
    }
}

getResourceAsStream("druid.properties");默认则是从ClassPath根下获取，path不能以’/'开头，ClassPath一般在WEB-INF\classes下

2.druid.properties配置文件放在src根目录
