mappingJarLocations，解决hbm文件被打成jar时读取路径问题
??????? <property name="mappingLocations">
??????????? <list>
??????????????? <value>classpath:com/test/hbm/*.hbm.xml</value>
??????????? </list>
??????? </property>???????
当hbm文件被打成jar包时，上面的方法就不能用了。幸亏org.springframework.orm.hibernate3.LocalSessionFactoryBean还有mappingJarLocations属性。
????? <property name="mappingJarLocations">
??????????? <list>
??????????????? <value>WEB-INF/lib/test.jar</value>
??????????? </list>
??????? </property>
?
这样就不怕被读不到文件了
