Java 使用Spring5和Hibernate5=>BeanDefinitionParsingException使用maven创建可执行jar时出现问题

更新： 因为现在只有一个答案，我现在试着更好地描述它

简而言之，我的测试应用程序在eclipse中运行良好，并且在使用mvn exec启动时运行良好，但构建运行/工作的可执行jar包不适用于此项目

现在是更长的描述。我学习Java大约8个月，使用maven设置构建项目，并将Eclipse作为IDE进行编写和调试。目前，我正在尝试使用Spring、Hibernate和用于测试H2的一些小型数据库项目。DAO类使用entityManager。编译和运行我的测试应用程序在eclipse和maven中运行良好。在eclipse中，我使用：

mvn exec:java-Dexec.mainClass=maven.springhibernateh2.basic.CRUDTest

那很好。我的问题是开始构建并运行一个可执行jar。 通常我会在pom.xml中添加一个插件部分，例如：

   <plugin>
     <artifactId>maven-assembly-plugin</artifactId>
     <version>3.2.0</version>
     <configuration>
       <descriptorRefs>
         <descriptorRef>jar-with-dependencies</descriptorRef>
       </descriptorRefs>
       <archive>
         <manifest>
           <mainClass>maven.springhibernateh2.basic.CRUDTest</mainClass>
         </manifest>
       </archive>
     </configuration>
     <executions>
       <execution>
         <id>make-assembly</id>
         <phase>package</phase>
         <goals>
           <goal>single</goal>
         </goals>
       </execution>
     </executions>
   </plugin>

不幸的是，我在这个项目中遇到了问题。错误消息是：

org.springframework.beans.factory.parsing.BeanDefinitionParsingException:配置问题：找不到XML架构命名空间的Spring NamespaceHandler[ 有问题的资源：类路径资源[Beans.xml]

由于项目正常运行，我预计构建可执行jar会有一些问题，并且我猜pom.xml在与bean定义的组合中缺少一些东西

现在是两个文件pom.xml和Beans.xml

这里是my pom.xml：

我根据Slobodan Margetić的建议做了一些实验，谢谢：-但不幸的是，这没有帮助。更改Beans.xml导致应用程序完全停止工作。 由于我的测试应用程序在Eclipse和maven中工作，我希望Beans.xml应该是正确的，但是pom.xml可能会遗漏一些东西

我发现： 因为我在pom.xml中有Dependency spring tx，所以它应该正常工作。不幸的是它不工作。最后一个叫Anuja的人写道： 一些SpringJAR包含同名的元信息文件。”因此，为了避免某些元文件被覆盖，我使用maven shade插件来合并它们 也许我的项目也是如此。我如何检查它？

---

有没有人对maven shade插件有经验，或者有人建议我可以尝试找到什么解决方案？

尝试将此用于beans：

           <beans xmlns="http://xmlns.jcp.org/xml/ns/javaee"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee                               http://xmlns.jcp.org/xml/ns/javaee/beans_2_0.xsd" bean-discovery-mode="all" version="2.0">
           </beans>

它应该能够通过文件找到bean
