关于配置XML的异常分析-Mybatis配置文件

org.apache.ibatis.builder.IncompleteElementException:

Could not find parameter map org.lanqiao.tjut.mapper.UsersMapper.UsersMapper；

异常是有关UsersMapper文件查找不到

有可能Mybatis.XML中的别名配置错误如：

<!-- 使用别名 -->
<typeAliases>
<typeAlias  alias="Users"  type="org.lanqiao.tjut.bean.Users"/>
</typeAliases>

而在Mapper包下如：

<mapper namespace="org.lanqiao.tjut.mapper.UsersMapper">
 <resultMap type="Users" id="UsersMapper">
<id column="userId" property="userId"/>
<result column="name" property="name"/> 
<result column="password" property="password"/> 
</resultMap> 
<select id="selectUserBeanList" resultMap="UsersMapper">
select * from USERS 
</select>
 <select id="selectUserBeanSome"  parametertype="Users" resultMap="UsersMapper" >
 select * from USERS WHERE USERID=#{userId}
 </select>
