Spring配置文件中读取Properties文件的配置

记录一下：

下面是Spring配置文件applicationContext.xml配置文件的代码片段：

<?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:context="http://www.springframework.org/schema/context"    xmlns:jdbc="http://www.springframework.org/schema/jdbc" xmlns:jee="http://www.springframework.org/schema/jee"    xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop"    xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:jpa="http://www.springframework.org/schema/data/jpa"    xmlns:util="http://www.springframework.org/schema/util"    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/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc.xsd        http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee.xsd        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd        http://www.springframework.org/schema/data/jpa http://www.springframework.org/schema/data/jpa/spring-jpa.xsd        http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd        http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd        http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util.xsd"><!-- 代码省略--><!-- 加载jdbc连接时需要的properties属性文件 -->    <context:property-placeholder location="classpath:jdbc.properties" /><!-- 代码省略--></beans>

另外一种方法：

在Spring配置文件中加入下面的代码，以便于配置：

<!-- 引入命名空间 -->xmlns:util="http://www.springframework.org/schema/util"  xsi:schemaLocation="http://www.springframework.org/schema/util          http://www.springframework.org/schema/util/spring-util-3.2.xsd"  <util:properties id="propertiesReader" location="classpath:property.properties" />

读取多个Properties文件的配置方法

<bean id="propertiesReader" class="org.springframework.beans.factory.config.PropertiesFactoryBean">      <property name="locations">      <list>          <value>classpath:file-1.properties</value>          <value>classpath:file_2.properties</value>      </list>      </property>  </bean>
