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
?xml version=”1.0” encoding=”UTF-8” ?>

明显是错误的，正确的应该这样子配置 !– 实体类,简称 -设置别名 –>
