SQLMap XML配置文件

SQLMap使用XML配置文件统一配置不同的属性，包括DataSource的详细配置信息，
SQLMap和其他可选属性，如线程管理等。以下是SQLMap配置文件的一个例子：
SqlMapConfig.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE sqlMapConfig
PUBLIC "-//iBATIS.com//DTD SQL Map Config2.0//EN"
"http://www.ibatis.com/dtd/sql-map-config-2.dtd">
<!-- Alwaysensure touse the correct XMLheader as above!-->
<sqlMapConfig>

<properties resource=" examples/sqlmap/maps/SqlMapConfigExample.properties " />
<!-- These settingscontrol SqlMapClientconfiguration details, primarilytodo withtransaction

<settings

/>
<!-- Typealiases allowyoutouse a shorter name for longfullyqualifiedclass names. -->
<typeAliasalias="order" type="testdomain.Order"/>
