aplictaionContext-dataSource的配置：

25         <property name="username">

31         <property name="maxActive">
32             <value>${sqlMaxActive}</value>
33         </property>
34         <property name="maxWait">
35             <value>${sqlMaxWait}</value>
36         </property>
37         <property name="maxIdle">
38             <value>${sqlMaxIdle}</value>
39         </property>
40     </bean>

42 </beans>

propertyConfigurer用来配置用到的config.properties文件的位置，方便在datasource配置中引用。
config配置文件的写法如下：

1 sqlDriver=com.mysql.jdbc.Driver
2 sqlUrl=jdbc:mysql://127.0.0.1:3306/mydatabase?useUnicode=true&amp;characterEncoding=utf8
3 sqlUserName=root
4 sqlPassword=123
5 sqlMaxActive=500
6 sqlMaxWait=1000
7 sqlMaxIdle=50
