一个有趣的关于spring的基础问题

Question

1、我在配置applicationContext.xml是引入properties文件使用

<beans:bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
      <beans:property name="location" value="classpath:jdbc.properties"/>
</beans:bean>

能够正常的启动tomcat，但是使用

<context:property-placeholder location="classpath:jdbc.properties"/>

在启动的过程中就会报错

完整的applicationContext.xml文件代码如下

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

    <!--&lt;!&ndash; 1.1 关联jdbc.properties &ndash;&gt;-->
    <context:property-placeholder location="classpath:jdbc.properties"/>
    <!--<beans:bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">-->
        <!--<beans:property name="location" value="classpath:jdbc.properties"/>-->
    <!--</beans:bean>-->
    <!-- 组件扫描配置 -->
    <beans:bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <beans:property name="basePackage" value="com.shiro.dao"/>
        <beans:property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
    </beans:bean>

    <!-- Session配置-->
    <beans:bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <beans:property name="dataSource" ref="dataSource"/>
        <beans:property name="mapperLocations" value="classpath:dal/*.xml"/>
    </beans:bean>

    <!-- 事务管理配置 -->
    <beans:bean id="dataSourceTransactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <beans:property name="dataSource" ref="dataSource"/>
    </beans:bean>
    <!-- 01.配置数据源 -->
    <beans:bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <beans:property name="driverClassName" value="${jdbc.driverClass}"></beans:property>
        <beans:property name="url" value="${jdbc.jdbcUrl}"></beans:property>
        <beans:property name="username" value="${jdbc.username}"></beans:property>
        <beans:property name="password" value="${jdbc.password}"></beans:property>
    </beans:bean>


</beans:beans>
