        Java 数据库连接，（Java Database Connectivity，简称JDBC）是Java语言中用来规范客户端程序如何来访问数据库的应用程序接口，提供了诸如查询和更新数据库中数据的方法。JDBC也是Sun Microsystems的商标。它JDBC是面向关系型数据库的（来源：维基百科   ）。JDBC是我们通过外部程序操作数据库的一个工具。
                                                                                                                                                                                                                                               
2、编写JDBC的步骤
    （1）加载驱动
    （2）传递参数获得连接
    （3）获取数据库连接  

    我在这里用了一个properties的配置文件来（database.properties）设置我的我的配置参数

        #mysqluse
        driver=com.mysql.jdbc.Driver
        url=jdbc:mysql://127.0.0.1:3306/dotestuse
        username=root
        password=
程序代码         
  1.             import java.io.IOException;
  2.             import java.io.InputStream;
  3.             import java.sql.Connection;
  4.             import java.sql.DriverManager;
  5.             import java.sql.SQLException;
  6.             import java.util.Properties;
  7.             
  8.             public class GetConnectionT {
  9.             
  10.                 public static void main(String[] args) {
  11.             
  12.                     try {
  13.             
  14.                         //读取配置文件参数
  15.                         InputStream in = GetConnectionT.class.getClassLoader().getResourceAsStream("propert.properties");
  16.                         Properties pr = new Properties();
  17.                         pr.load(in);
  18.                         Class.forName(pr.getProperty("driver"));
  19.                         //通过驱动管理器获得数据库连接        
  20.                         Connection con = DriverManager.getConnection(pr.getProperty("url"),    pr.getProperty("username"), pr.getProperty("password"));
  21.                         System.out.println(con);
  22.                         con.close();
  23.             
  24.                     } catch (ClassNotFoundException e) {
  25.             
  26.                         System.err.println("加载驱动失败"+e.getLocalizedMessage());
  27.                     } catch (IOException e) {
  28.                         System.err.println("加载配置文件失败"+e.getLocalizedMessage());
  29.                     } catch (SQLException e) {
  30.                         System.err.println("建立数据库连接失败"+e.getLocalizedMessage());
  31.                     }
  32.                 }
  33.             }

这里只是一个简单的获得JDBC的例子，在实际工作中我们最好用单例模式来获得数据库连接

显示信息如下：

运行插入语句始终不能成功，但是一直没有注意这个语句
530  DEBUG [main] org.apache.ibatis.transaction.jdbc.JdbcTransaction     - Rolling back JDBC Connection [com.mysql.jdbc.JDBC4Connection@5f8172]
想一想在insert里面也没有用到事务啊，不知道是什么原因？

在执行语句出添加事务提交 就可以插入成功 ，

        SqlSession sqlsesstion = sc.openSession();

        sqlsesstion.insert("insertperson", person);
        sqlsesstion.commit();  //还不知道是什么原因要提交事务才可以插入数据成功，但是每一次似乎都对数据库产生了影响
        sqlsesstion.close();



有一点乱 ！！！

          找到 Getter and Setter   添加自己需要的快捷键即可
    （2）设置添加实现接口方法或覆盖父类的方法
           找到  Override or implement methods  即可

2、配置eclipse 启动需要的环境（启动jdk的时候报错需要配置）
（
A Java Runtime Environment (JRE) or Java Development Kit (JDK)
must be available in order to run Eclipse. No Java virtual machine
was found after searching the following locations:
）
   
   在eclipse 的配置文件中添加（eclipse.ini）  
    -vm
    D:\devlopgrame\java\jdk\bin\javaw.exe

3、eclipse 安装插件（以svn为例）
    （1）下载svn的解压包site_1.6.18
    （2）解压安装包到一个磁盘位置 如：D:\learn\Eclipse\pluginsetorsoure\svnplug\site_1.6.18
    （3）建立连接文件svn.link（eclipse\dropins）      
        path=D:/learn/Eclipse/pluginsetorsoure/svnplug/site_1.6.18（注意路径格式为/）

]]>安装joomla步骤http://www.blogjava.net/gnl/archive/2012/09/01/386774.html一江一江Sat, 01 Sep 2012 15:32:00 GMThttp://www.blogjava.net/gnl/archive/2012/09/01/386774.htmlhttp://www.blogjava.net/gnl/comments/386774.htmlhttp://www.blogjava.net/gnl/archive/2012/09/01/386774.html#Feedback0http://www.blogjava.net/gnl/comments/commentRss/386774.htmlhttp://www.blogjava.net/gnl/services/trackbacks/386774.html

安装joomla步骤

注：

1.本示例教程安装环境是apache+mysql+joomla安装包

2.注意mysq数据库的设置，因为joomla的运行环境是需要数据库的支持的

3.在安装程序的最后主要参数设置的时候注意参数设置如是否安装示例数据库

  （示例数据对于一学习程序是十分需要的）

把joomla安装包拷贝到apache的htdocs文件夹里面，在浏览地址输入

本地配置服务器的访问路径开始安装joomla
