MyBatis - typeAliases不能正确解析问题的处理方法

Mybatis配置文件中使用typeAliases竟然报错，错误提示：

?

1	the content of element type "configuration" must match "(properties?,settings?,typeAliases?,typeHandlers?,objectFactory?,objectWrapperFactory?,reflectorFactory?,plugins?,environments?,databaseIdProvider?,mappers?)".

这个问题居然是typeAliases和environments元素在configuration中顺序引起的！！

最终总结：“configuration”中的元素必须按照上面错误提示中的元素顺序加入，如果前面的元素没有，可以忽略，但是所有元素的顺序不能颠倒，否则就会报上面错误！！

引起错误时候的配置：

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28

<?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="com.mysql.jdbc.Driver" />                 <property name="url"                     value="jdbc:mysql://localhost:3306/jpetstore?autoReconnect=true&useUnicode=true&characterEncoding=utf-8" />                 <property name="username" value="root" />                 <property name="password" value="trymybest" />             </dataSource>         </environment>     </environments>       <typeAliases>         <package name="org.mybatis.model" />     </typeAliases>       <mappers>         <package name="org.mybatis.mapper" />     </mappers> </configuration>

修改后，正常工作的配置：

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28

<?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>       <typeAliases>         <package name="org.mybatis.model" />     </typeAliases>       <environments default="development">         <environment id="development">             <transactionManager type="JDBC" />             <dataSource type="POOLED">                 <property name="driver" value="com.mysql.jdbc.Driver" />                 <property name="url"                     value="jdbc:mysql://localhost:3306/jpetstore?autoReconnect=true&useUnicode=true&characterEncoding=utf-8" />                 <property name="username" value="root" />                 <property name="password" value="trymybest" />             </dataSource>         </environment>     </environments>       <mappers>         <package name="org.mybatis.mapper" />     </mappers> </configuration>
