解决 IllegalArgumentException: Could not resolve placeholder in string value "${XXXXXX}"

如题：

导致这一问题的原因：使用了重复的property-placeholder

如一个配置文件中使用了

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

而另一处使用了

<bean id="propertyConfigurer">
          <!--class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">-->
        <property name="locations">-->
            <list>
                <value>classpath:bb.properties</value>
            </list>
        </property>
    </bean>

解决：

主要从以下几个地方去解决：

1. 去掉一处的propertyConfigurer配置，替换成context:property-placeholder

2. 两处都添加ignore-unresolvable="true"

配置文件1：

<context:property-placeholder location="classpath:aa.properties" ignore-unresolvable="true" />

配置文件2：

<context:property-placeholder location="classpath:bb.properties" ignore-unresolvable="true" />

练习SSM项目的demo中遇到一个问题,我在applicationContext.xml中使用了<context:property-placeholder location="classpath:jdbc.properties"/>,我还想再引入另外一个resource.properties,resource.properties中的key我在controller层引用,用的是@Value(value="${type}")注解,总是出现如题的问题,从网上

Could not resolve placeholder 'IMAGE_SERVER_URL' in string value "${IMAGE_SERVER_URL}"

出现错误的主要原因是:property-placeholder重复使用解决:加上ignore-unresolvable="true"即可如下: Could not resolve placeholder 'IMAGE_SERVER_URL' in string value "${IMAGE_SERVER_URL}" 原文地址:https://www.cnblogs.com/rgever/p/10355515.html

Could not resolve placeholder 'from' in string value "${from}" 解决: 在spring的xml配置文件中当有多个*.properties文件需要加载时, 应当集中在一个xml文件中加载,建议在主xml文件中加载,即(applicationContext.xml)中加载, 这样就不需要关注子xml文件与 *.properties 加载顺序问题加载多个*.properties文件,以','隔开 <context:pr
