Question

我创建了一个 hotelContactInfo.json 文件，我正在尝试使用 JHipster 生成代码：

{
    "fluentMethods": true,
    "relationships": [
        {
            "relationshipName": "hotel",
            "otherEntityName": "hotel",
            "relationshipType": "one-to-one",
            "otherEntityField": "id",
            "ownerSide": true,
            "otherEntityRelationshipName": "hotelContactInfo"
        }
    ],
    "fields": [
        {
            "fieldName": "ownerName",
            "fieldType": "String",
            "fieldValidateRules": [
                "required"
            ]
        },
        {
            "fieldName": "emails",
            "fieldType": "String[]",
            "fieldValidateRules": [
                "required"
            ]
        },
        {
            "fieldName": "mobiles",
            "fieldType": "String[]",
            "fieldValidateRules": [
                "required"
            ]
        },
        {
            "fieldName": "deskInfo",
            "fieldType": "String"
        },
        {
            "fieldName": "address",
            "fieldType": "String",
            "fieldValidateRules": [
                "required"
            ]
        },
        {
            "fieldName": "website",
            "fieldType": "String"
        },
        {
            "fieldName": "createdBy",
            "fieldType": "String",
            "fieldValidateRules": [
                "required"
            ]
        },
        {
            "fieldName": "createdDate",
            "fieldType": "LocalDate",
            "fieldValidateRules": [
                "required"
            ]
        },
        {
            "fieldName": "modifiedBy",
            "fieldType": "String"
        },
        {
            "fieldName": "modifiedDate",
            "fieldType": "LocalDate"
        }
    ],
    "changelogDate": "20180822085850",
    "dto": "no",
    "service": "serviceImpl",
    "entityTableName": "hotel_contact_info",
    "pagination": "infinite-scroll",
    "microserviceName": "hcm",
    "searchEngine": "elasticsearch",
    "enableEntityAudit": false
}

生成代码时，JHipster 实体 HotelContactInfo:

Executing jhipster:entity HotelContactInfo
Options:

? Do you want to update the entity? This will replace the existing files for this entity, all your custom code will be overwritten Yes, re generate the entity

Answer 1

您的意思是您hotelContactInfo.json文件手动创建或编辑了吗？

您应该通过导入 JDL 文件或回答实体生成器的问题来 create/update 实体，因为这是检查语法的方式。通过直接编辑 json 文件，您将自行承担绕过此阶段的风险。

在这里，我怀疑 "fieldType": "String[]" 是无效的，因为它不是 type supported by JHipster。
