Mybatis配置文件

jericho0702

　　今天发现Mybaits的配置文件校验很诡异，节点的位置还有要求
　　如下，会报错：

The content of element type "configuration" must match "(properties?,settings?,typeAliases?,typeHandlers?,objectFactory?,objectWrapperFactory?,plugins?,environments?,mappers?)".
 
<?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="oracle.jdbc.driver.OracleDriver"/>
<property name="url" value="jdbc:oracle:thin:@xx:1521:xx"/>
<property name="username" value="ireport"/>
<property name="password" value="xxxx"/>
</dataSource>
</environment>
</environments>
<typeAliases>
<typeAlias type="com.ice.stat.online.model.EventFlag" alias="EventFlag"/>
</typeAliases>
<mappers>
<mapper resource="com/ice/stat/online/model/hbm/EventFlagMapper.xml"/>
</mappers>
</configuration>

 　　把typeAliases放到最上面就好了说：

<?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>
<typeAlias type="com.ice.stat.online.model.EventFlag" alias="EventFlag"/>
</typeAliases>
<environments default="development">
<environment id="development">
<transactionManager type="JDBC"/>
<dataSource type="POOLED">
<property name="driver" value="oracle.jdbc.driver.OracleDriver"/>
<property name="url" value="jdbc:oracle:thin:@xx:1521:xx"/>
<property name="username" value="ireport"/>
<property name="password" value="xxxx"/>
</dataSource>
</environment>
</environments>

<mappers>
<mapper resource="com/ice/stat/online/model/hbm/EventFlagMapper.xml"/>
</mappers>
</configuration>
