MyBatis：Parameter Maps collection does not contain value for 的问题解决

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。
