Question

运行以下代码时：

 <entity-find entity-name="mantle.order.OrderHeaderPartFacilityStatus" list="orderPartList">
                <econdition field-name="facilityId" from = "facilityId"/>
                <econdition field-name="statusId" operator="in" value="OrderPlaced,"/>

                <!-- <select-field field-name="orderId, "/> -->
                <!-- <select-field field-name="orderName"/> -->
                <!-- <select-field field-name="placedDate"/> -->
                <!-- <select-field field-name="grandTotal"/> -->
                <!-- <select-field field-name="orderPartSeqId"/> -->
                <!-- <select-field field-name="facilityId"/> -->
                <!-- <select-field field-name="facilityName"/> -->
                <!-- <select-field field-name="partStatusId"/> -->
                <!-- <order-by field-name="orderPartSeqId"/> -->
        </entity-find>

我得到了：

 "orderPartList": [
    {
        "enteredByPartyId": null,
        "salesChannelEnumId": null,
        "recurrenceInfoId": null,
        "customerRoleTypeId": "Manager",
        "billingAccountId": null,
        "placedDate": "2016-01-01T00:00:00+0000",
        "telecomContactMechId": null,
        "postalContactMechId": null,
        "vendorRoleTypeId": null,
        "visitId": null,
        "lastOrderedDate": null,
        "remainingSubTotal": null,
        "trackingNumber": null,
        "otherPartyOrderId": null,
        "statusId": "OrderPlaced",
        "giftMessage": null,
        "entryDate": null,
        "shippingInstructions": null,
        "autoCancelDate": null,
        "estimatedDeliveryDate": null,
        "customerPartyId": "EX_JOHN_DOE",
        "validThruDate": null,
        "carrierPartyId": null,
        "partTotal": 5.1E+2,
        "facilityId": "FWorkshopnanneihuan",
        "syncStatusId": null,
        "estimatedShipDate": null,
        "validFromDate": null,
        "estimatedPickUpDate": null,
        "externalRevision": null,
        "orderPartSeqId": "01",
        "terminalId": null,
        "shipmentMethodEnumId": null,
        "shipBeforeDate": null,
        "parentOrderId": null,
        "isGift": null,
        "productStoreId": null,
        "orderRevision": 26,
        "dontCancelSetDate": null,
        "pseudoId": "FWorkshopnanneihuan",
        "dontCancelSetUserId": null,
        "systemMessageRemoteId": null,
        "maySplit": null,
        "externalId": null,
        "parentPartSeqId": null,
        "facilityName": "\u5357\u5185\u73af\u8f66\u95f4",
        "orderId": "FOJohndoePassat",
        "vendorPartyId": null,
        "shipAfterDate": null,
        "currencyUomId": null,
        "orderName": "John_doe order 1",
        "grandTotal": 5.1E+2,
        "partStatusId": "OrderOpen",
        "partName": "\u7b2c\u4e00\u90e8\u5206 John doe",
        "statusDescription": "Placed"
    }
],

但是当我取消注释select-field标记时，如下所示：

 <entity-find entity-name="mantle.order.OrderHeaderPartFacilityStatus" list="orderPartList">
                <econdition field-name="facilityId" from = "facilityId"/>
                <econdition field-name="statusId" operator="in" value="OrderPlaced,"/>

                <select-field field-name="orderId, "/>
                <!-- <select-field field-name="orderName"/> -->
                <!-- <select-field field-name="placedDate"/> -->
                <!-- <select-field field-name="grandTotal"/> -->
                <!-- <select-field field-name="orderPartSeqId"/> -->
                <!-- <select-field field-name="facilityId"/> -->
                <!-- <select-field field-name="facilityName"/> -->
                <!-- <select-field field-name="partStatusId"/> -->
                <!-- <order-by field-name="orderPartSeqId"/> -->
        </entity-find>

然后我收到以下错误消息，这可能表明select sql无法正常工作：

{"errorCode":500,"errors":"java.lang.IllegalArgumentException: Maps with null keys can't be converted to JSON"}

出了什么问题？我正在使用自定义数据运行MoquiDemo-2.0.0。它可能是一个bug还是什么？有人有线索吗？

Answer 1

字段名称＆＃34; orderId，＆＃34;无效。逗号用于分隔多个字段名称，因此它将其转换为＆＃34; orderId＆＃34;和＆＃34;＆＃34;，并且空字符串不是有效的字段名称。

同样在您对statusId的处理中，@ value属性在结尾处有逗号。如果您尝试包含null statusId的记录，请使用econdition。@ or-null属性。要获得更有效的查询，如果不是您要查找的内容，请删除逗号并使用等号运算符（这是默认设置，因此您不需要运算符属性）。

一般来说，这段代码很草率。 Moqui试图容忍有趣的事情并尽力而为，但是无效的字段名称仍然无效，你会得到错误。您可能在服务器端日志中有更多错误或警告，这通常是第一个查看某些内容是否正常工作的地方。

使用select-field的entity-find给出错误消息
