发现配置：

<resultMap type="com.demo.sys.entity.Module" id="moduleMap"><id property="id" column="id" /><result property="name" column="name" /><result property="remark" column="remark" /><result property="createDate" column="createdate" /><result property="updateDate" column="updateDate" /><association property="parent" column="parent_id"resultMap="moduleMap" select="queryModule"></association><collection property="childs" column="parent_id"javaType="ArrayList" ofType="com.demo.sys.entity.Module"select="queryChildList"></collection></resultMap><select id="queryList" parameterMap="moduleMap" resultMap="moduleMap">select * from sys_module where id =#{id}</select>

更改配置：

?

<resultMap type="com.demo.sys.entity.Module" id="moduleMap"><id property="id" column="id" /><result property="name" column="name" /><result property="remark" column="remark" /><result property="createDate" column="createdate" /><result property="updateDate" column="updateDate" /><association property="parent" column="parent_id"resultMap="moduleMap" select="queryModule"></association><collection property="childs" column="parent_id"javaType="ArrayList" ofType="com.demo.sys.entity.Module"select="queryChildList"></collection></resultMap><select id="queryList"  parameterType="com.demo.sys.entity.Module" resultMap="moduleMap">select * from sys_module where id =#{id}</select>

parameterMap="moduleMap" -------》parameterType="com.demo.sys.entity.Module"

?

解决了Mybatis中Parameter Maps collection does not contain value for xxx 的问题了。

?

查看Mybatis官方资料：

SQL映射的XML文件：parameterMap 已经废弃了，现在使用parameterType来处理。
