明显在解析xml配置文件的时候出现的异常，

从org.xml.sax.SAXParseException; lineNumber: 30; columnNumber: 17; 元素类型为 "configuration" 的内容必须匹配 "(properties?,settings?,typeAliases?,typeHandlers?,objectFactory?,objectWrapperFactory?,plugins?,environments?,databaseIdProvider?,mappers?)"。可以明显的看出mybatis的配置文件显然是有顺序并且个数是有限定的，‘？’表示可以没有但是最多只能有一个，但是自己的配置中

<typeAliases>
<typeAlias alias="User" type="com.silence.mybatis.enties.User" />
</typeAliases>

<typeAliases>
<typeAlias alias="Article" type="com.silence.mybatis.enties.Article" />
</typeAliases>

明显是错误的，正确的应该这样子配置

<typeAliases>
<typeAlias alias="User" type="com.silence.mybatis.enties.User" />
<typeAlias alias="Article" type="com.silence.mybatis.enties.Article" />
</typeAliases>
