spring分散配置方式

目录结构如下:

在web.xml中配置如下:

 

    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath*:spring-config.xml</param-value>
    </context-param>

指定spring的纲要配置文件 spring-config.xml

 

spring-config.xml 内容:

 

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:jee="http://www.springframework.org/schema/jee"
	xmlns:tx="http://www.springframework.org/schema/tx" xmlns:p="http://www.springframework.org/schema/p"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:aop="http://www.springframework.org/schema/aop"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd"
	default-autowire="byName">

    <!-- 属性文件读入 -->
	<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
		<property name="locations">
			<list>
				<value>classpath:props/*.properties</value> <!--指定数据源等配置文件 -->
			</list>
		</property>
	</bean>
    <import resource="classpath:spring/*.xml"/>
  
</beans>

dataSource.properties 中存储了一些数据源的信息:

 

 

driverClassName=com.microsoft.sqlserver.jdbc.SQLServerDriver
url=jdbc:sqlserver://localhost:1433;DatabaseName=ots_vacation
username=sa
password=18662766385whF

接着,在spring文件夹中,将不同的bean写在不同的xml中即可.

注意下使用了配置文件模式的数据源配置文件:

	<!-- 数据源部分 -->
    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
        <property name="driverClassName" value="${driverClassName}"/>
        <property name="url" value="${url}"/>
        <property name="username" value="${username}"/>
        <property name="password" value="${password}"/>
    </bean>

 

 

 

这样的好处,看起来调理非常清晰.
