（Hybris）如何获取MapType值

Question

userAddressMap的I Impex数据->可以，并且值为：[B@785db42b

我想获取(key, value)的值userAddressMap

我的Item.xml和jsp文件如下：（无效）

<maptypes>
    <maptype code="addressMap" argumenttype="java.lang.String"
        returntype="java.lang.String" autocreate="true" generate="false" />
</maptypes>


<itemtype generate="true" code="Band" autocreate="true">
        <deployment table="Bands" typecode="30268" />
        <attributes>
            <attribute qualifier="code" type="java.lang.String">
                <description>short unique code of band</description>
                <persistence type="property" />
            </attribute>
            <attribute qualifier="name" type="java.lang.String">
                <description>name of band</description>
                <persistence type="property" />
            </attribute>
            <attribute qualifier="history" type="java.lang.String">
                <description>history of band</description>
                <persistence type="property" />
            </attribute>
            <attribute qualifier="albumSales" type="java.lang.Long">
                <description>official global album sales</description>
                <persistence type="property" />
            </attribute>
            <attribute qualifier="userAddressMap" type="addressMap">
                <modifiers unique="false" read="false" />
                <persistence type="property" />
            </attribute>
        </attributes>
    </itemtype>

和我的jsp文件：

<c:forEach var="userAddressMap" items="${band.userAddressMap}">
    <tr>
        <td>${userAddressMap.key}</td>
        <td><input TYPE="text" NAME="${userAddressMap.key}" VALUE="${userAddressMap.value}" SIZE="100"></td>
    </tr>
</c:forEach>
