1.在field-validator的message中含有{0}

例如

common.required = {0} is required.common.family = Family

<field name="family.familyName">        <field-validator type="requiredstring">            <param name="trim">true</param>            <message key="common.required">                <argo key="common.family" />            </message>        </field-validator>    </field>

以上写法，输出的message为{0} is required，不是预期的Family is required.

解决方法一

common.required = ${getText(fieldName)} is required.family.familyName = Family

<field name="family.familyName">    <field-validator type="requiredstring">        <param name="trim">true</param>        <message key="common.required"/>    </field-validator></field>

解决方法二

<field name="family.familyName">        <field-validator type="requiredstring">            <param name="trim">true</param>            <message>                ${getText("requiredstring", {getText("common.family")})}            </message>        </field-validator>    </field>
