J2EE SSH2架构(3)

第三个架构,与第二个相似性很大,唯一不同的是采用的是hibernate.cfg.xml配置文件,如下:

<?xml version="1.0" encoding="GBK"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

	</tx:advice>

	<!-- 哪些类的哪些方法参与事物, (* com.evan.crm.service.*.*(..))中几个通配符的含义:

		第四个 .. —— 通配 方法可以有0个或多个参数

	<!-- Clob 类型处理配置 BEGIN -->
	<bean id="defaultLobHandler" lazy-init="true"

	-->
</beans>
