Spring抛出异常，试图使用Jasypt加密属性占位符解析属性占位符

我正在尝试使用Jasypt的加载加密的属性EncryptablePropertyPlaceholderConfigurer。

这是我的应用程序上下文，其中包含令人讨厌的Bean和加密的属性占位符Bean：

<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"
       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">

    <context:property-placeholder/>

    <bean class="com.blahblah.OffendingBean">
        <property name="user" value="${my.user}"/>
        <property name="password" value="${my.password}"/>
    </bean>

    <bean id="propertyConfigurer"
          class="org.jasypt.spring3.properties.EncryptablePropertyPlaceholderConfigurer">
        <constructor-arg ref="configurationEncryptor"/>
        <property name="ignoreUnresolvablePlaceholders" value="true"/>
        <property name="locations">
            <list>
                <value>credentials.properties</value>
            </list>
        </property>
    </bean>

    <bean id="configurationEncryptor" class="org.jasypt.encryption.pbe.StandardPBEStringEncryptor">
        <property name="config" ref="environmentVariablesConfiguration"/>
    </bean>

    <bean id="environmentVariablesConfiguration"
          class="org.jasypt.encryption.pbe.config.EnvironmentStringPBEConfig">
        <property name="algorithm" value="PBEWithMD5AndDES"/>
        <property name="password" value="not telling you"/>

    </bean>
</beans>

注意我已经<property name="ignoreUnresolvablePlaceholders" value="true"/>设置了属性占位符。

我已经在调试器中逐步解决了这个问题，似乎另一个Property Placeholder实例来自某个地方，并决定未在任何地方设置$ {my.user}并引发异常。

奇怪的是，这工作得很好-我不知道我改变了什么来打破了这一点。

可以肯定地找到了prop文件“ credentials.properties”-EncryptablePropertyPlaceholderConfigurer并未对此抱怨。它绝对具有其中定义的属性my.user。甚至Intellij也在编辑器中进行替换！

旁注，不认为这是相关的，但是此春季上下文是通过Jersey 2 servlet上下文加载的。

这是例外：
