何创建本地数据库并连接JDBC

总结了一下前人的做法然后自己试着做了一下干到晚上4点,终于将MySQL JDBC驱动配置成功了

首先,下载mySQL 软件,地址为:

http://dev.mysql.com/downloads/

安装装在默认路径里C:\Program Files\MySQL

如果在安装过程中初始化出现失败的时候,那么很有可能是因为port被引用或者之前安装过端口被占用,清除注册表中关于mysql的记录,然后完全卸载之后重新安装

打开安装好的MySQL 查找到本机地址:localhost 数据库名: ,用户名:root, 密码自己设置一个。

进入DOS模式,然后用cd命令进入C:\Porgram Files\MySQL\MySQL Server\bin的目录下(为默认安装目录),然后输入mysql –h localhost –u root –p 敲回车

然后出现enter password

输入密码

然后会出现

DOS 连接本地MySQL 数据库

证明mySQL连接成功了

然后通过这个就可以操作mySQL

1.mysql>show databases;

DOS 连接本地MySQL 数据库

2.mysql>create database sample;

DOS 连接本地MySQL 数据库

 

3. use sample;

  Insert into user values(‘sway’,’1234556’);

然后下载mySQLJDBC的驱动 地址为

http://dev.mysql.com/downloads/connector/j/

下载完了之后解压缩,然后解压缩到你自己定义的路径里面。里面有个.jar格式的文件,

我们要把这个文件安装到eclipse里面,可以通过手动操作也可以通过在eclipse里面建立路径,我使用的是第二种方法。如下:

4.eclipse里面新建一个java project,命名为JDBCTest

DOS 连接本地MySQL 数据库

5.建立完project之后,会在左边的一栏看到

DOS 连接本地MySQL 数据库

6.右击JDBCTest 找到build path,然后点击add external archives

7.       选中之前下载的JDBC driver  mysql-connector-java-5.1.19-bin.jar

DOS 连接本地MySQL 数据库

然后你就会看到JDBCTest 下面referenced libraries 的下面就有这个驱动

DOS 连接本地MySQL 数据库

8.       右击JDBCTest 新建class,然后命名Mysqljdbc.class

DOS 连接本地MySQL 数据库

9.       code复制到class,

 

import java.sql.*;

public classMysqlJdbc {

  publicstaticvoidmain(String args[]) {

    try{

      Class.forName("com.mysql.jdbc.Driver");     //加载MYSQL JDBC驱动程序   

      //Class.forName("org.gjt.mm.mysql.Driver");

     System.out.println("Success loading Mysql Driver!");

    }

    catch(Exception e) {

      System.out.print("Error loading Mysql Driver!");

      e.printStackTrace();

    }

    try{

      Connection connect = DriverManager.getConnection(

          "jdbc:mysql://localhost/sample","root","song1024");

           //连接URL   jdbc:mysql//服务器地址/数据库名  ,后面的2个参数分别是登陆用户名和密码

 

      System.out.println("Success connect Mysql server!");

      Statement stmt = connect.createStatement();

      ResultSet rs = stmt.executeQuery("select * from user");

                                                              //user 为你表的名称

      while(rs.next()) {

        System.out.println(rs.getString("name"));

      }

    }

    catch(Exception e) {

      System.out.print("get data error!");

      e.printStackTrace();

    }

  }

}

 

然后run 就会在底下得对话框出现success loading

PS: code要仔细看过,该修改的地方一定要修改才行运行,不要不看直接运行那是不行的

Explain the InnoDB Buffer Pool and its importance for performance.Explain the InnoDB Buffer Pool and its importance for performance.Apr 19, 2025 am 12:24 AM

InnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.
