ssh整合之六管理我们的配置文件
1.我们的ssh搭建已经搭建好了，之前是纯xml方式，而且我们的配置文件，是一个框架一个配置文件。这样的话，配置文件中的内容就会很多，这样以后修改起来也会很麻烦,因 此，我们尝试着把这些配置文件引入进来，进行一个分类管理，这样，再修改的话就会方便很多，对于我们快速查阅配置文件也有好处
2.下面我们对之前的配置文件进行改造,先来看看我们的一个大体上的结构，这里我们的hibernate的核心配置文件，即hibernate.cfg.xml，我们是直接交给了spring进行管理
3.这里我们把spring的核心配置文件分开，这样的话，易于维护和查看,最后，我们可以在spring的核心文件中引入其他配置文件即可
config/spring/applicationContext-customer.xml
<?xml version="1.0" encoding="UTF-8"?> <!-- spring的配置文件：导入约束 --> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd "> <!-- 自定义的java对象交给spring进行管理 --> <bean id="customerAction" scope="prototype" class="com.itheima.action.CustomerAction"> <property name="customerService" ref="customerService"></property> </bean> <bean id="customerService" class="com.itheima.service.impl.CustomerServiceImpl"> <property name="customerDao" ref="customerDao"></property> </bean> <bean id="customerDao" class="com.itheima.dao.impl.CustomerDaoImpl"> <property name="hibernateTemplate" ref="hibernateTemplate"></property> </bean> </beans>

4.我们的struts也分开管理
config/struts/struts-customer.xml
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN" "http://struts.apache.org/dtds/struts-2.3.dtd"> <struts> <package name="customer" extends="struts-default" namespace="/customer"> <action name="addCustomerUI" class="customerAction" method="addCustomerUI"> <result name="success">/jsp/customer/add.jsp</result> </action> <action name="getAllCustomer" class="customerAction" method="getAllCustomer"> <result name="success">/jsp/customer/list.jsp</result> </action> </package> </struts>
struts的狠心配置文件struts.xml
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
"http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>
<constant name="devMode" value="true"></constant>
<!-- 引入其他的struts的动作类配置文件 -->
<include file="config/struts/struts-customer.xml"></include>
</struts>
这样的话，我们就把配置文件分门别类了，到时候再修改或查看时就一目了然了！
