最近由于项目需要，需要jar项目来处理。

我在项目中整合了Spring，在编辑器中启动没有问题，但是使用ant打包为一个完整jar文件，部署后启动报错如下

org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Unable to locate Spring NamespaceHandler for XML schema namespace [http://www.springframework.org/schema/context]

关于这个问题网上说有很多原因：

1、比如spring版本不统一

2、缺少spring依赖  http://www.baeldung.com/unable-to-locate-spring-namespacehandler-for-xml-schema-namespace

但是都不是我遇到的情况。

　　最后，有大神说：功夫不负有心人，在仔细地对比和排查原因之后，发现了问题的所在，在我的jar包下的META-INF目录下，有两个跟spring相关的文件：spring.handlers、spring.schemas，打开这两个文件一看，里面都只包含了spring-tx的配置

spring.handlers

　　和我的情况很吻合。

spring.handlers:

http\://www.springframework.org/schema/mvc=org.springframework.web.servlet.config.MvcNamespaceHandler

spring.schemas:

http\://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd=org/springframework/web/servlet/config/spring-mvc-3.0.xsd

http\://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd=org/springframework/web/servlet/config/spring-mvc-3.1.xsd

http\://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd=org/springframework/web/servlet/config/spring-mvc-3.2.xsd

http\://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd=org/springframework/web/servlet/config/spring-mvc-4.0.xsd

http\://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd=org/springframework/web/servlet/config/spring-mvc-4.1.xsd

http\://www.springframework.org/schema/mvc/spring-mvc-4.2.xsd=org/springframework/web/servlet/config/spring-mvc-4.2.xsd

http\://www.springframework.org/schema/mvc/spring-mvc.xsd=org/springframework/web/servlet/config/spring-mvc-4.2.xsd

诸如类似吧，反正里面没有spring-context包对应的spring.handlers和spring.schemas。当然会报错。

原因如：http://stackoverflow.com/questions/1937767/spring-3-0-unable-to-locate-spring-namespacehandler-for-xml-schema-namespace

解决方案：

maven：

<plugin>

    <groupId>org.apache.maven.plugins</groupId>

    <artifactId>maven-shade-plugin</artifactId>

    <version> 1.7.1</version>

    <executions>

        <execution>

            <phase>package</phase>

            <goals>

                <goal>shade</goal>

            </goals>

            <configuration>

                <transformers>

                    <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>

                    <transformer

                        implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">

                        <mainClass>com.chenzhou.test.Main</mainClass>

                    </transformer>

                </transformers>

            </configuration>

        </execution>

    </executions>

</plugin>

　　其中两个AppendingTransformer，主要是把spring.handlers和spring.schemas以追加的方式构建到jar文件中。防止因为工程中依赖了多个spring文件，而后面的META-INF/spring.handlers和META-INF/spring.schemas会把前面的覆盖掉。导致错误。

参考大神文章：

http://chenzhou123520.iteye.com/blog/1971322

http://chenzhou123520.iteye.com/blog/1706242

ant：

由于ant的使用地方不是太多了，我也不太熟悉，没有找到完整的配置。我提供一些参考文章

　　https://stackoverflow.com/questions/5586515/idea-to-avoid-that-spring-handlers-spring-schemas-get-overwritten-when-merging-m

我们的项目用的也是ant，暂时的解决方案是，不把spring的包打包进runnable.jar中，而是把spring-*.jar与runnable.jar放入同级目录，这样spring启动的时候会自动识别，虽然暂时解决了问题，但是不太优雅，如果各位大神有什么更优雅的解决方案，望不吝赐教！

问题和方案就写到这里，整理一下，放假回家过年。各位，狗年大吉。
