Oracle数据库连接池问题在tomcat下的配置

1.tomcat配置

<Context path="/manager" docBase="../server/webapps/manager"
debug="0" privileged="true"></Context>

<Context path="" docBase="f:/test" debug="0" reloadable="true">
<Resource name="test" auth="Container" type="javax.sql.DataSource"/>
<ResourceParams name="test">
<parameter>
<name>factory</name>
<value>org.apache.commons.dbcp.BasicDataSourceFactory</value>
</parameter>
<parameter>
<name>driverClassName</name>
<value>oracle.jdbc.driver.OracleDriver</value>
</parameter>
<parameter>
<name>url</name>
<value>jdbc:oracle:thin:@192.168.0.1:shark</value>
</parameter>
<parameter>
<name>username</name>
<value>aqgl</value>
</parameter>
<parameter>
<name>password</name>
<value>welcome</value>
</parameter>
<parameter>
<name>maxActive</name>
<value>20</value>
</parameter>
<parameter>
<name>maxIdle</name>
<value>10</value>
</parameter>
<parameter>
<name>maxWait</name>
<value>-1</value>
</parameter>
</ResourceParams>

</Context>
<Logger className="org.apache.catalina.logger.FileLogger"
directory="logs" prefix="ystatistics_log." suffix=".txt"
timestamp="true"/>
2.连接池类

package com;

import java.sql.Connection;

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

public class GetCon {

public Connection getCon() throws Exception {
InitialContext initialcontext = new InitialContext();
DataSource datasource = (DataSource) initialcontext
.lookup("java:comp/env/assistpro");
Connection connection = (Connection) datasource.getConnection();

return connection;
}

}

3.测试jsp

<%@ page import="javax.naming.Context" %>
<%@ page import="javax.sql.DataSource"%>
<%@ page import="javax.naming.InitialContext"%>
<%@ page import="java.sql.*"%>
<%@ page import="com.GetCon"%>

test start<br>
<%
GetCon getcon = new GetCon();
Connection conn = getcon.getCon();
if(conn!=null){
out.print("Connection OK!");
}
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("select * from task");
while(rs.next()){
out.print(rs.getString(1));
out.print("<br>");

}

%>
