spring分散配置方式

目錄結構如下:

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的綱要設定檔 spring-config.xml

spring-config.xml 內容:

<?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">    <!-- 屬性檔案讀入 --><bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"><property name="locations"><list><value>classpath:props/*.properties</value> <!--指定資料來源等設定檔 --></list></property></bean>    <import resource="classpath:spring/*.xml"/>  </beans>

dataSource.properties 中儲存了一些資料來源的資訊:

driverClassName=com.microsoft.sqlserver.jdbc.SQLServerDriverurl=jdbc:sqlserver://localhost:1433;DatabaseName=ots_vacationusername=sapassword=18662766385whF

接著,在spring檔案夾中,將不同的bean寫在不同的xml中即可.

注意下使用了設定檔模式的資料來源設定檔:

<!-- 資料來源部分 -->    <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>

這樣的好處,看起來調理非常清晰.
