文档根元素“配置”，必须匹配DOCTYPE根“空”

Question

嗨我想连接Spring MVC到MySQL使用MyBatis。在设置时，我收到类似以下错误消息：

org.xml.sax.SAXParseException: Document root element "configuration", must match DOCTYPE root "null"。

谷歌搜索后，我发现它与Spring版本有些相关。但我不明白100％。我尝试在pom.xml中更改一些依赖版本，但没有解决它。希望有人告诉我究竟是什么问题，以及如何解决.below是完整的错误消息和pom.xml。对不起我的英语，并感谢您的关注。我会很感激你的回答。

Answer 1

MyBatis的XML配置文件应该是这样this：

<?xml version="1.0" encoding="UTF-8" ?> 
<!DOCTYPE configuration 
     PUBLIC "-//mybatis.org//DTD Config 3.0//EN" 
     "http://mybatis.org/dtd/mybatis-3-config.dtd"> 
<configuration> 
    <environments default="development"> 
    <environment id="development"> 
     <transactionManager type="JDBC"/> 
     <dataSource type="POOLED"> 
     <property name="driver" value="${driver}"/> 
     <property name="url" value="${url}"/> 
     <property name="username" value="${username}"/> 
     <property name="password" value="${password}"/> 
     </dataSource> 
    </environment> 
    </environments> 
    <mappers> 
    <mapper resource="org/mybatis/example/BlogMapper.xml"/> 
    </mappers> 
</configuration> 

你错过“DOCTYPE “ statement？
