MyBatis configuration file, note the label configuration order. Otherwise error the content of element type "configuration" must match "(Properties?,settings?,... How to Solve

Thank the original author http://www.cnblogs.com/zhoumingming/p/5417014.html

Note that each label must be written in order, or it will prompt an error

Order is

<?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>

<!--load Properties file--
<properties resource= "Db.properties" >
<!--properties You can also configure some property names and property values-
<!--<property name= "jdbc.driver" value= ""/>-
</properties>

<!--global configuration parameters, when needed and set-

<settings>
<!--Open the delay-loaded switch--
<setting name= "lazyloadingenabled" value= "true"/>
<!--to change active load to negative load that loads as needed

<!--alias Definition--
<typeAliases>

<!--defined for a single alias
Type: The path of the types
Alias: Aliases
-
<!--<typealias type= "Cn.itcast.mybatis.po.User" alias= "User"/>-
<!--batch alias definition
Specifies the package name, MyBatis automatically scans the PO class in the package, and automatically defines the alias, which is the class name (either uppercase or lowercase)
-
<package name= "Cn.itcast.mybatis.po"/>

</typeAliases>

<!--and spring are integrated after the environments configuration will be abolished--

</environments>
<!--load a mapping file--

<!--load one mapping file at a time with the resource method--
<!--<mapper resource= "Mapper/usermapper.xml"/>--

<!--loading a single mapping file via the Mapper interface
Follow some specifications: You need to keep the Mapper interface class name and the Mapper.xml mapping file name consistent and in one directory
The prerequisite for the above specification is that the Mapper proxy method is used
-

<!--bulk Load Mapper
Specifies the package name of the Mapper interface, MyBatis automatically scans all mapper interfaces underneath the package for loading

</configuration>

That's roughly the order.
