运行时报错，说找不到xml文件

参考博客https://blog.csdn.net/daiyutage/article/details/53739452
原因是Spring Framework的多个jar包中包含相同的文件spring.handlers和spring.schemas，如果生成一个jar包会互相覆盖。为了避免互相影响，可以使用AppendingTransformer来对文件内容追加合并：

添加
  <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>
