mybatis的resultMap property爆红

 <resultMap id="userMap" type="com.cast.pojo.User">        <id column="id" property="userId"/>        <result column="username" property="userName"/>        <result column="sex" property="userSex"/>        <result column="birthday" property="userBirthday"/>        <result column="address" property="userAddress"/>    resultMap>

mybatis的resultMap property爆红
虽然我写了全路径类名，但是就是不能找到实体类的属性，最后的原因，就是在SQL的配置文件sqlMapperConfig.xml中添加别名，而且要写在环境的上边，写下下边configuration爆红

   <typeAliases>        <typeAlias type="com.cast.pojo.User" alias="user"/>    typeAliases>    DOCTYPE configuration        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"        "http://mybatis.org/dtd/mybatis-3-config.dtd"><configuration>      <typeAliases>        <typeAlias type="com.cast.pojo.User" alias="user"/>    typeAliases>    <environments default="mysql">        <environment id="mysql">            <transactionManager type="JDBC">transactionManager>            <dataSource type="POOLED">                <property name="driver" value="com.mysql.jdbc.Driver"/>                <property name="url" value="jdbc:mysql://localhost:3306/mybatis"/>                <property name="username" value="root"/>                <property name="password" value="654321"/>            dataSource>        environment>    environments>        <mappers>        <mapper resource="com/cast/dao/UserDao.xml">mapper>    mappers>configuration>

最后不要忘了，修改映射文件Daomapper.xml中的路径
直接写别名，全路径已经换为别名了

<resultMap id="userMap" type="user">        <id column="id" property="userId"/>        <result column="username" property="userName"/>        <result column="sex" property="userSex"/>        <result column="birthday" property="userBirthday"/>        <result column="address" property="userAddress"/>    resultMap>
