mybatis3这个问题我晕为什么对于配置信息的节点放的位置也会报错

今天配置mybatis3时不小心配置成了下面的这样，结果就报一大堆的错误，说是配置文件的问题，我勒个去。我晕。

配置文件的配置信息如下：（其中就是把别名放在了environments节点元素的上面。结果就报这个错误。我晕。

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration
PUBLIC "-//ibatis.apache.org//DTD Config 3.0//EN"
"http://ibatis.apache.org/dtd/ibatis-3-config.dtd">
<configuration>
<typeAliases>
<typeAlias alias="myuser" type="com.action.Users" />
</typeAliases>
<!-- 加载jdbc.properties -->
    <properties resource="jdbc.properties"/>
    <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>
    <!-- 加载映射文件 -->
    <mappers>
        <mapper resource="com/action/User.xml"/>
    </mappers>
</configuration>

错误信息如下：

后来就把上面的配置文件中的别名放在了environments节点的下面，调试通过。我晕！我擦！

我勒个去。

真是太没道理了。知道你mybatis3现在框架不错，又是apache的产品。但是你也不能这样做的纠结人啊。我没法说你去。、

 

没天理啊！
