想法，以避免spring.handlers / spring.schemas合并在一个jar中的多个弹簧依赖关系时被覆盖
我得到的错误Unable to locate NamespaceHandler when using context:annotation-config运行（java -jar）由maven-assembly-plugin组装并包含我的项目及其所有依赖项的jar。
正如其他人正确地在forum.springsource.org 线程（消息＃7/8）上发现了问题，因为存在于不同jar中的文件META-INF/spring.handlers和META-INF/spring.schemas被覆盖当maven-assembly-plugin将jar包重新打包成一个文件时。
查看两个spring – *。jar文件的内容，可以看到文件与classpath相对应的位置相同
$ jar tf spring-oxm-3.0.3.RELEASE.jar META-INF/spring.handlers META-INF/spring.schemas org/springframework/oxm/GenericMarshaller.class ... $ jar tf spring-context-3.0.3.RELEASE.jar META-INF/spring.handlers META-INF/spring.schemas org/springframework/context/ApplicationContext.class
是不是可以将META-INF文件夹放在特定的包中？ 如果是这样的想法，我会build议，（希望它适用）是把META-INF/spring.shemas和META-INF/spring.handlers文件放在它们引用的包下。
$ jar tf spring-oxm-3.0.3.RELEASE.jar org/springframework/oxm/META-INF/spring.schemas org/springframework/oxm/META-INF/spring.handlers org/springframework/oxm/GenericMarshaller.class ... $ jar tf spring-context-3.0.3.RELEASE.jar org/springframework/context/META-INF/spring.handlers org/springframework/context/META-INF/spring.schemas org/springframework/context/ApplicationContext.class
这样，它们在单个jar中合并时不会发生冲突。 你怎么看待这件事？
我设法摆脱使用着色器插件而不是（buggy）汇编程序插件的错误：
<plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-shade-plugin</artifactId> <executions> <execution> <phase>package</phase> <goals> <goal>shade</goal> </goals> <configuration> <transformers> <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer"> <mainClass>at.seresunit.lecturemanager_connector.App</mainClass> </transformer> <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> </transformers> </configuration> </execution> </executions> </plugin>
我认为我在springource论坛上find了解决scheme..从我查阅起来已经有相当长的一段时间了..不能真正记住作者。 无论如何，他的荣誉：第
干杯
