grails 3.1.3弱参考设置器无法工作的多个数据源

标签： grails

我之前没有遇到过这种情况，比如grails 2，所以不确定这是不正确的行为，还是有错误。

我已经按照文档和我的application.groovy我有dataSources的默认情况和一个额外的名为countrycity

在我的城市课上我有

package com.example.info

class City {
  String code

  static mapping={
   datasource 'countrycity'
  }
}

和其他域类

package com.example.users
class Address {

  Long city

  City getCity() {
     return City.get(city)
  }
  //void  setCity(City c) {city=c.id}
}

如果没有启动setter，应用程序就会正常启动，我启用void setCity行的那一刻我得到一个像这样的堆栈跟踪：

答案 0 :(得分：1)

当您将String code添加到Groovy类（在本例中为Grails域类）时，它看起来像一个公共（或可能是包默认）字段，但它是一个属性。 Groovy编译器会将其转换为具有相同名称的实际私有字段，以及关联的getter和setter方法（String getCode()和void setCode(String)）。如果您已经定义了getter或setter，或者Groovy都不会覆盖你的，那么它只会添加缺少的内容。

这适用于GORM，因为Hibernate并不了解Groovy属性 - 它所寻找的是匹配的getter / setter对，它们被解释为属性。它不知道您的类是来自Java源还是Groovy源，或者这些方法是由Groovy生成还是由您手动输入。

你已经有一个＆＃34;城市＆＃34; Long类型的属性，添加City getCity()可以让你在一半到一秒。当你添加setter时你有两个相同的名字，但有不同的类型，如果Hibernate没有抱怨你似乎想要坚持一个它不知道如何工作的类型，它将自行失败用。

因此，您需要重命名其中一个 - 我与Long cityId一起使用，因为它更具自我描述性，并且会在city_id列中创建{{1}}列。数据库就像你将外键映射到一个城市一样。表
