使用虚拟路径配置Tomcat项目

<Context path="/" docBase="E:\MyWorkSpace\xm_zycj\WebRoot" reloadable="true" crossContext="true">
				<Resource name="jdbc/liaoyang" 
				  type="javax.sql.DataSource" 
				  password="z9z7w7w8" 
				  driverClassName="oracle.jdbc.driver.OracleDriver" 
				  maxIdle="2" 
				  maxWait="50" 
				  username="zycj" 
				  url="jdbc:oracle:thin:@127.0.0.1:1521:orcl" 
				  maxActive="4"/> 
</Context>
			
<Context path="/cms" docBase="E:\MyWork\cms\WebRoot" reloadable="true" crossContext="true"/>

server.xml中的host元素中写Context。

获得：

import javax.naming.Context;
import javax.naming.InitialContext;
import javax.sql.DataSource;

private Context env;
private DataSource source;


env = (Context) new InitialContext().lookup("java:comp/env");
source = (DataSource) env.lookup("jdbc/liaoyang");

Connection conn = null;
conn = source.getConnection();
