Eclipse pom引用mysql 5.5.15失败简单的解决方案

1. 测试Maven的时候发现引用 mysql-connector-java-5.1.10-bin.jar

有点问题    搞了好久还是没解决 

索性用最简单的方法   直接新建一个文件夹lib 然后进行引用

程序结构如下:

2.pom.xml代码已经注释了

3.java部分代码

package mm.mm;

/**
 * Hello world!
 *
 */
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;

public class Apptest {
    public static void main(String[] args) {
        try {
            Class.forName("com.mysql.jdbc.Driver");
            long start = System.currentTimeMillis();
            try (Connection conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/test", "root", "root")) {
                long end = System.currentTimeMillis();
                System.out.println("建立连接耗时：" + (end - start) + "ms 毫秒");
            }
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }
}
