Maven Shade插件的Spring 3 NamespaceHandler问题 [英] Spring 3 NamespaceHandler issues with Maven Shade plugin

问题描述

使用Apache Maven 3.0.3和Maven Shade插件1.6的Spring 3.1.1.RELEASE.

Spring 3.1.1.RELEASE with Apache Maven 3.0.3 and Maven Shade plugin 1.6.

使用mvn shade插件将工件包装在uber-jar中，包括其依赖项:

Using the mvn shade plugin to package the artifact in an uber-jar, including its dependencies:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-shade-plugin</artifactId>
    <version>1.6</version>
    <executions>
        <execution>
        <phase>package</phase>
        <goals>
            <goal>shade</goal>
        </goals>
        <configuration>
            <transformers>
                <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
                    <mainClass>com.MyApplication</mainClass>
                </transformer>
            </transformers>
        </configuration>
    </execution>
</executions>

似乎可以打包，但是在执行时会抱怨Spring NamespaceHandler问题:

Seems to package just fine but on execution complains of Spring NamespaceHandler issues:

Caused by: org.springframework.beans.factory.parsing.BeanDefinitionParsingException:
Configuration problem: Unable to locate Spring NamespaceHandler for XML schema namespace [http://www.springframework.org/schema/util]
Offending resource: class path resource [spring/test-context.xml]

这同时适用于util和p命名空间，但希望它不仅限于这些:

This applies to both the util and p-namespaces, but expect it's not limited to these:

xmlns:util="http://www.springframework.org/schema/util"
xmlns:p="http://www.springframework.org/schema/p"

如果我改写了该属性或列表(实用程序)，问题将消失.

If I rewrite the property or list (util) longhand the issues disappear.

推荐答案

尝试添加

Try adding an AppendingTransformer to your config. The example specifically mentions this as being useful for Spring handlers.
