【中文标题】在 grails 中迁移 mongodb 插件时发生异常【英文标题】：Exception occurred in migrating mongodb plugin in grails 【发布时间】：2017-03-17 06:36:05 【问题描述】：我正在将我的 grails 项目从 2.4.4 迁移到 3.2.0。所以我也将我的 gorm-mongodb 插件从 3.0.2 迁移到 6.0.0。以前的 mongo 版本是 2.4.12，当前版本是 3.2.7。 我有一个域类：
class Query implements Serializable, Validateable
static mapWith = "mongo"
ObjectId id
String queryId
String applicationId
String importTime
String importFile
Boolean active
Boolean disableHighlight
Map<String, String> name
Map<String, String> help
Map<String, String> purpose
List<QuerySection> sections
List<QuerySection> includedSections
List<EntitySummaryData> summaryData
Boolean componentQuery
Boolean allowMonthlyData
Boolean showResourceUnit
List<QueryFilter> supportedFilters
static mapping =
version false
static embedded = ["sections", "summaryData", "includedSections", "supportedFilters"]
static constraints =
sections nullable: true
active nullable: true
disableHighlight nullable: true
help nullable: true
importTime nullable: true
importFile nullable: true
summaryData nullable: true
componentQuery nullable: true
allowMonthlyData nullable: true
applicationId nullable: true
includedSections nullable: true
supportedFilters nullable: true
showResourceUnit nullable: true
static transients = [
"localizedName",
"localizedPurpose",
"mandatoryQuestions",
"questionsBySection",
"localizedHelp",
"allQuestions",
"allSections",
"importTimeAsDate"
]
在我的数据库转储中，我有字符串格式的版本字段。这是我在此域中的数据库中的数据： "_id" : ObjectId("512afda9285e71e809e8c72b"), “活跃”：假， “版本”：“2012.1”
这是我的代码：
BuildableCriteria criteria = Query.createCriteria()
inactiveQueries= criteria.list
or
eq('active', Boolean.FALSE)
isNull('active')
and
order('queryId', 'asc')
order('importTime', 'desc')
使用以前版本的 grails 和 mongodb-gorm 3.0.2，我的应用程序正在使用此版本字段，但是当我将我的 gorm-mongodb 插件迁移到 6.0.0 时，此代码通过异常：
org.springframework.core.convert.ConversionFailedException: Failed to convert from type [java.lang.String] to type [java.lang.Long] for value '2012.1'; nested exception is java.lang.NumberFormatException: For input string: "2012.1"

【问题讨论】：
【参考方案1】：您的数据库中有与模型不匹配的数据。数据库中存在 2012.1 的值 version 属性，而在您的模型中，您试图用 Long 表示 version 属性（Long 是 GORM 中 version 属性的默认类型)。
由于2012.1 无法转换为Long，因此您会遇到异常。通过禁用版本控制或数据来更正您的模型，问题就会消失。
【讨论】：
我通过在映射块中放置版本映射 false 来禁用版本。但它仍然无法正常工作。有没有其他方法可以禁用版本控制？ 在你的域类中定义String version
好的。谢谢你。我会这样做的。以上是关于在 grails 中迁移 mongodb 插件时发生异常的主要内容，如果未能解决你的问题，请参考以下文章
