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；

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><transformerimplementation="org.apache.maven.plugins.shade.resource.AppendingTransformer"><resource>META-INF/spring.handlers</resource></transformer><transformerimplementation="org.apache.maven.plugins.shade.resource.AppendingTransformer"><resource>META-INF/spring.schemas</resource></transformer><transformerimplementation="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>                    <descriptorRefs>                        <descriptorRef>jar-with-dependencies</descriptorRef>                    </descriptorRefs>                    <archive>                        <manifest>                            <mainClass>com.payplat.dacq.impl.AutoJob</mainClass>                        </manifest>                    </archive>                </configuration>                <executions>                    <execution>                        <id>make-assembly</id>                        <phase>package</phase>                        <goals>                            <goal>single</goal>                        </goals>                    </execution>                </executions>            </plugin>-->            <plugin>                <groupId>org.apache.maven.plugins</groupId>                <artifactId>maven-shade-plugin</artifactId>                <version>2.1</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>                            </transformers>                        </configuration>                    </execution>                </executions>            </plugin>        </plugins>    </build>

然后重新打包 mvn package就没问题了。
