【问题描述】：

我正在尝试构建一个可执行的 jar，并在运行时收到以下错误：

INFO：从类路径资源 [spring-app.xml] 加载 XML bean 定义线程“主”org.springframework.beans.factory.parsing.BeanDefinitionParsingException 中的异常：配置问题：找不到 XML 模式命名空间的 Spring NamespaceHandler [http://www.springframework.org/schema/jms] 违规资源：类路径资源[spring-app.xml]

我的 spring-app.xml 如下：

【解决方案1】：

这是我添加到我的 maven-shade-plugin 的内容，并且它起作用了。shade 插件提供了附加 jar 文件（如属性和 xml 文件）中存在的资源的选项。 AppendingTransformer 用于普通文件。XmlAppendingTransformer 用于 xml 文件。

<transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
  <resource>META-INF/spring.handlers</resource>
</transformer>
<transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
  <resource>META-INF/spring.schemas</resource>
</transformer>

【讨论】：

遇到了同样的问题，使用其他命名空间 (util)，但这也适用于我。

【解决方案2】：

尝试使用 spring 的版本化 xsd 名称，例如：

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:jms="http://www.springframework.org/schema/jms"
xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/beans      
            http://www.springframework.org/schema/beans/spring-beans.xsd
            http://www.springframework.org/schema/tx 
            http://www.springframework.org/schema/tx/spring-tx.xsd
            http://www.springframework.org/schema/context
            http://www.springframework.org/schema/context/spring-context-4.0.xsd
            http://www.springframework.org/schema/jms
            http://www.springframework.org/schema/jms/spring-jms-4.0.xsd">
