使用maven打包jar后 执行jar包问题，Exception in thread "main" org.springframework.beans.factory.parsing.BeanDefi

    本人第一次发帖写的不是很好。希望大家体谅体谅。。。
最近研究maven，然后用maven管理项目，打包项目后发现执行就报错，上网差了很久终于解决了。
废话不多说了，看下面。
很多人使用maven打包后执行jar出现一个错误；

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

在打包时后面的会把前面的覆盖，使得这两个文件中永远只保存最后一个spring依赖的schema和handler。

主要把这两个加上就没问题了

<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>

这是maven的shade打包

<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>

 这是maven的assemby打包

<build>
        <plugins>
           <!-- <plugin>
                <artifactId>maven-assembly-plugin</artifactId>

                </configuration>

                <executions>
                    <execution>

                    </execution>
                </executions>
            </plugin>-->

            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-shade-plugin</artifactId>

                                </transformer>
                                <transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
                                    <resource>META-INF/spring.schemas</resource>

                            </transformers>

                </executions>
            </plugin>
        </plugins>
    </build>

然后重新打包 mvn package就没问题了。
