java - Spring上下文错误: SAXParseException cvc-complex-type. 3.2.2忽略无法解析的上下文:属性占位符

Question

我正在尝试使用 JUnit 测试加载 Spring 应用程序上下文，但遇到了架构错误。

这是它尝试加载的上下文文件:

                                            classpath*:/META-INF/spring/blah-${foo.environment}.properties,

                                  ignore-unresolvable="true" />

    <import resource="classpath:/META-INF/spring/blah-context.xml" />

</beans>

有趣的是，应用程序启动良好，似乎只有 JUnit 测试出现了问题。

我正在使用 Spring 3.2.6。

我查看了类路径，以确保没有任何冲突的 JAR，并且所有内容似乎都在同一版本上。

该堆栈跟踪的深处是消息“不允许属性‘ignore-unresolvable’出现在元素‘context:property-placeholder’中。”我应该想象这条消息的意思正是它所说的。您的 xsi:schemaLocation 指向此处的架构:

http://www.springframework.org/schema/context/spring-context.xsd

果然，元素 property-placeholder 的声明不允许使用此属性。
