请问再tomcat里面能不能配置连接池？如果能，该怎么配置？谢谢

希望在tomcat配置文件里面配置连接池，确定数据连接数，请问改如何配置？

一、 server.xml的配置
<Context path="/test" docBase="test" debug="0" reloadable="true">
<Logger className="org.apache.catalina.logger.FileLogger" prefix="localhost_DBTest_log." suffix=".txt" timestamp="true"/>
<Resource name="jdbc/MysqlDB" auth="Container" type="javax.sql.DataSource"/>
<ResourceParams name="jdbc/MysqlDB">
<parameter>
<name>factory</name>
<value>org.apache.commons.dbcp.BasicDataSourceFactory</value>
</parameter>
<parameter>
<name>maxActive</name>
<value>100</value>
</parameter>
<parameter>
<name>maxIdle</name>
<value>30</value>
</parameter>
<parameter>
<name>maxWait</name>
<value>10000</value>
</parameter>
<parameter>
<name>username</name>
<value>root</value>
</parameter>
<parameter>
<name>password</name>
<value>root</value>
</parameter>
<parameter>
<name>driverClassName</name>
<value>org.gjt.mm.mysql.Driver</value>
</parameter>
<parameter>
<name>url</name> <value>jdbc:mysql://192.168.16.101:3306/egu_gx?useUnicode=true&characterEncoding=GB2312</value>
</parameter>
</ResourceParams>
</Context>
二、web.xml 的配置
<resource-ref>
<description>DB Connection</description>
<res-ref-name>jdbc/MysqlDB</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
三、获取连接的代码
public Connection getConnection() {
try {
Context initCtx = new InitialContext();
Context ctx = (Context) initCtx.lookup("java:comp/env");
//获取连接池对象
Object obj = (Object) ctx.lookup("jdbc/MysqlDB");
//类型转换
javax.sql.DataSource ds = (javax.sql.DataSource) obj;
conn = ds.getConnection();
}
catch (Exception ex) {
ex.printStackTrace();
conn = null;
}
return conn ;
}
