有两种方法:
1.简便配制方法
在D:\Program Files\Apache Software Foundation\Tomcat 7.0\conf\server.xml文件中的<Host></Host>标签之间加入如下的Context代码
<Context path="/test" docBase="test" debug="0" reloadable="true" crossContext="true">
<Resource name="jdbc/test" auth="Container" type="javax.sql.DataSource" maxActive="10" maxIdle="5" maxWait="10000" username="sa" password="sasa" driverClassName="net.sourceforge.jtds.jdbc.Driver" url="jdbc:jtds:sqlserver://localhost:1433/mydb"/>
</Context>
2.官方推荐方法
首先配置tomcat下的conf下的context.xml文件,在之间添加连接池如下:
<Resource name="jdbc/test" auth="Container" type="javax.sql.DataSource" maxActive="10" maxIdle="5" maxWait="10000" username="sa" password="sasa" driverClassName="net.sourceforge.jtds.jdbc.Driver" url="jdbc:jtds:sqlserver://localhost:1433/test"/>
然后配置你的应用下的web.xml中的之间加入:
<resource-ref>
<description>DB Connection</description>
<res-ref-name>jdbc/test</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
