java - Spring编译的Jar中的org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException

我环顾四周，所以没有找到可以为我解决此问题的解决方案。我有一个使用Spring的Maven项目，我将其称为Assembly-Single并构建了一个可运行的jar。该项目在IDE中运行良好，但是当我将其作为可运行的jar运行时，出现以下异常：

org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 8 in
 XML document from class path resource [properties.xml] is invalid; nested excep
tion is org.xml.sax.SAXParseException; lineNumber: 8; columnNumber: 62; cvc-elt.
1.a: Cannot find the declaration of element 'beans'.
        at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.doLoadB
eanDefinitions(XmlBeanDefinitionReader.java:396)
        at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.loadBea
nDefinitions(XmlBeanDefinitionReader.java:334)
[...]

我的properties.xml文件如下所示。注意我的schemaLocation正确，第8行是http://www.springframework.org/schema/context

<?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:context="http://www.springframework.org/schema/context"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xmlns:util="http://www.springframework.org/schema/util"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
http://www.springframework.org/schema/util
http://www.springframework.org/schema/util/spring-util-3.0.xsd">

    <context:property-placeholder
        location="classpath:test.properties"  system-properties-mode="OVERRIDE"/>

<!-- -->

</beans>

最佳答案

环顾其他解决方案，我发现有人建议将xsd的类路径直接放入bean标记中。所以我继续尝试了。

<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"
    xmlns:util="http://www.springframework.org/schema/util"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
classpath:/org/springframework/beans/factory/xml/spring-beans-3.2.xsd
http://www.springframework.org/schema/context
classpath:/org/springframework/context/config/spring-context-3.2.xsd
http://www.springframework.org/schema/util
classpath:/org/springframework/beans/factory/xml/spring-util-3.2.xsd">
</beans>

此解决方案似乎适用于bean，但不适用于上下文。我的下一个解决方案是研究一段时间前发现的一篇文章，该文章可能与Maven覆盖spring.schemas文件而不是附加到文件（this solution）有关。我意识到我的spring.schemas仅包含MVC模式，因此我考虑了使用Maven Shade构建我的jar (using this as an example)的建议。阴影将允许一个转换器，该转换器将告诉maven追加到文件，而不是覆盖以允许多个依赖项使用同一文件。
