------配置问题

原因是: ***-mapper.xml文件中的 resultMap字段后面的值找不到

解决：

1、确保mybatis.xml和***-resultmap.xml文件在classpath中的相对位置正确，并配置正确

2、 ***-mapper.xml文件中，将resultMap字段后面的值加上 ***-resultmap.xml文件中的mapper的namespace，也就是namespace.resultMapID.

-------------------------

例如:

有***-resultmap.xml配置

<mapper namespace="accountMap">

  <resultMap type="AccountAlias" id="accountResultMap">

<id property="accountId" column="account_id" javaType="Integer" jdbcType="INTEGER"/>

<result property="status" column="status" javaType="Integer" jdbcType="INTEGER"/>

    </resultMap>

</mapper>

那么在***-mapper.xml文件中应该是

<select id="getAllAccount" resultType="list" resultMap="accountMap.accountResultMap">

<!-- 自动生成id策略 -->
<insert id="addAccount" useGeneratedKeys="true" keyProperty="account_id"
parameterType="account">

useGeneratedKeys="true" keyProperty="account_id"
