使用spring 5和hibernate 5用maven创建一个可执行的jar的问题 => BeanDefinitionParsingException

问题描述 投票：0回答：1

更新:由于目前只有一个答案，我现在试着描述一下比较好。

简而言之，我的测试程序在eclipse中和用mvn exec启动时运行得很好，但构建一个运行中的可执行jar包对这个项目不起作用。

现在长一点的描述。我学习Java大约8个月了，用maven来设置构建项目，用Eclipse作为IDE来编写和调试。目前我正在尝试使用Spring、Hibernate做一些小型的数据库项目，用于测试H2。DAO类使用实体管理器。编译和运行我的测试应用程序在eclipse和maven中都能正常工作。在eclipse中，我使用

mvn exec:java -Dexec.mainClass="maven.springghibernateh2.basic.CRUDTest"。

这很好用。我的问题是开始构建和运行一个可执行的jar.通常我习惯于在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>

通常，当maven exec命令工作时，这就足够了，看起来像e.g.一样。

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

不幸的是，我在这个项目中遇到了问题。错误信息是

org.springframework.beans.factory.parsing.BeanDefinitionParsingException: 配置问题：无法定位Spring NamespaceHandler for XML schema namespace []。http:/www.springframework.orgschematx] 违规资源：类路径资源[Beans.xml] 。

由于项目正常运行，我希望在构建可执行的jar时出现一些问题，我猜测pom.xml与beans定义的组合中缺少一些东西。

现在有两个文件pom.xml和Beans.xml。

这是我的pom.xml。

我按照Slobodan Margetić的建议做了一些实验(谢谢你:-) )，但不幸的是没有任何帮助。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，但希望pom.xml能错过一些东西。

我发现了这个。https:/www.baeldung.comunable-to-locate-spring-namespacehandler-for-xml-schema-namespace因为我的 pom.xml 中有依赖的 spring-tx，所以它应该正常工作。不幸的是，它没有工作。最后一个叫Anuja的人写道："有些spring jars包含了同名的元信息文件。" 因此，为了避免一些元文件被覆盖，我使用maven-shadode-plugin来合并它们 "也许我的项目也可以这样。如何检查呢，有人有经验吗？maven-shadow-plugin 或建议我可以尝试找到一个解决方案？

试着用这个来处理bean。

           <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>

它应该能让它通过文件找到bean。

如果它不工作，尝试通过这个链接阅读。http:/www.mastertheboss.comjboss-frameworkscdiconfiguring-beans-xml-file
