无需编程从sql导出到mysql的方法_MySQL
如果只是对MySql感兴趣可以照抄这篇短文,如果想配置其他数据库类型的连接池,也可以做简单修改参数即可使用。
1、安装Tomcat
参考Tomcat for window 的安装向导,基本直接安装即可,注意:安装时会提示输入管理用户名和密码,这是以后会用到的用户名和密码,切记。
2、安装MySql
默认安装即可。
3、使用Tomcat的Web管理应用配置数据源
启动Tomcat服务器,打开浏览器,输入http://localhost:8080/admin/(其中localhost可能是一台机器的IP或是服务器名称),进入管理界面的登陆页面,这时候请输入原来安装时要求输入的用户名和密码,登陆到管理界面,
选择Resources-Data sources进入配置数据源界面,选择Data Source Actions ->选择Create New Data Source,进入配置详细信息界面,内容如下:
JNDI Name: jdbc/mysql
Data Source URL: jdbc:mysql://192.168.0.16/SUBRDB
JDBC Driver Class: org.gjt.mm.mysql.Driver
User Name: root
Password: ********
Max. Active Connections: 4
Max. Idle Connections: 2
Max. Wait for Connection: 500
Validation Query:
要求输入的JNDI Name等信息,其中除了JDBC DriverClass之外,其他的可以根据你的需要填写。比如Data Source URL的内容可能是:jdbc:mysql:// IP或是名称/DataBaseName,其中DataBaseName是你的数据库名称,IP是你的数据库的所在的服务器的IP或是名称。最后点击Save->Commit Change.这样你的数据源的基本资料配置一半了。
4、web.xml和%TOMCAT_HOME%/conf/Catalina/localhost下对应你的引用的配置文件修改
通过文件夹导航到%TOMCAT_HOME%/conf,打开web.xml,在的前面添加以下内容:
注意res-ref-name填写的内容要与在上文提到的JNDI Name名称一致。
通过文件夹导航到%TOMCAT_HOME%/conf/Catalina/localhost下,找到你的web应用对应的.xml文件,如 ROOT.xml,并在此文件的下添入代码:
到这里,配置工作就基本完成了。
5、其他注意事项
别忘了JDBC驱动程序mysql-connector-java-3.0.9-stable-bin.jar一定要放置到Tomcat的对应目录,你的JDBC驱动可能版比笔者高,不过只要能与所使用的MySql对应就可以了,因为我发现版本太低的JDBC驱动不能支持4.0.*版本的MySQL数据库,建议放置在%TOMCAT_HOME%/common/lib和应用的WEB-INF/lib下。两者有什么不同呢?其实一看就明白了,common/li是所有的应用都可以使用的库文件位置。
重启你的Tomcat服务。
6、编写测试代码
在应用的目录下建立一个Test.jsp文件,代码如下:
