mybatis配置文件各元素顺序要求

在搭建mybatis环境的时候，报了个如下Error信息：

Cause: org.apache.ibatis.builder.BuilderException: Error creating document instance.  Cause: org.xml.sax.SAXParseException: The content of element type "configuration" must match "(properties?,settings?,typeAliases?,typeHandlers?,objectFactory?,objectWrapperFactory?,plugins?,environments?,databaseIdProvider?,mappers?)".

mybatis版本3.2.7

反复查看mybatis的配置文件，没有发现问题。

遂百度下子。

有网友说，Mybatis是适用DTD作为XML的校验文档，而XML规范中DTD顺序是有严格要求的。

于是打开Mybatis的DTD文件，按照DTD中定义的顺序重新调整mybatis配置文件的顺序，执行，OK。

Mybatis的DTD文件：http://mybatis.org/dtd/mybatis-3-config.dtd

 元素顺序：

properties

settings

typeAliases

typeHandlers

objectFactory

objectWrapperFactory

plugins

environments?

databaseIdProvider

mappers

我的最终Mybatis配置文件：

 1 <?xml version="1.0" encoding="UTF-8" ?>

 4   "http://mybatis.org/dtd/mybatis-3-config.dtd">
