java - Spring 配置文件和属性占位符异常

Question

我正在尝试使用配置文件从一个环境切换到另一个环境，这是我的应用程序上下文文件:

<?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:mongo="http://www.springframework.org/schema/data/mongo"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:p="http://www.springframework.org/schema/p" 
    xmlns:c="http://www.springframework.org/schema/c"
    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/data/mongo http://www.springframework.org/schema/data/mongo/spring-mongo.xsd">


    <context:property-placeholder properties-ref="deployProperties" />

    <!--  Mongo config -->
    <bean id="mongo" class="org.springframework.data.mongodb.core.MongoClientFactoryBean">
        <property name="host" value="${mongoHSRealtime.host.ip}"/>
        <property name="port" value="${mongoHSRealtime.host.port}"/>
    </bean> 

    <mongo:db-factory id="mongoDbFactory" mongo-ref="mongo"/>

    <!-- ###### ENVIRONMENET SPECIFIC SETTINGS ######### -->
    <beans profile="localhost">
        <bean id="deployProperties" p:location="classpath:localhost/spring.properties" class="org.springframework.beans.factory.config.PropertiesFactoryBean" />
    </beans>

    <beans profile="dev">   
        <bean id="deployProperties" p:location="classpath:dev/spring.properties" class="org.springframework.beans.factory.config.PropertiesFactoryBean" />
    </beans>

</beans>

在 web.xml 上，我定义了以这种方式激活哪个配置文件:

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/spring/coreConfig/application-context.xml</param-value>
</context-param>
<context-param>
    <param-name>log4jConfigLocation</param-name>
    <param-value>classpath:localhost/log4j.xml</param-value>
</context-param>    
<context-param>
    <param-name>spring.profile.active</param-name>
    <param-value>localhost</param-value>
</context-param>    

所以，一切看起来都很好，但是，当我尝试运行 tomcat 时，我得到了这个异常:

有什么线索吗？属性文件位于正确的位置，因为我可以使用此配置属性 location 和 property-placeholder 来访问。

请将spring.profile.active更改为spring.profiles.active。
