由于堆栈跟踪指出，发生该错误的原因是用户的email字段为空。

这意味着User user= new User(params)失败。这是因为你给出了错误的参数来初始化用户，例如，“用户类”没有“地址”属性。您应该改为new Employer()。

但是，如果您在插入之前看到我正在渲染的参数，则会打印出我提供的所有参数，我将其更改为Employer，并且仍然获取字段错误，但不知何故这些值变为空值。但我通过值 – srisris 2011-06-09 08:29:16

@srisris：是的，值仍然有，但格式错误。由于您的域名相当复杂，我建议您在保存之前手动在控制器中设置Employer的属性。 – 2011-06-09 10:43:56

更改为雇主是正确的。接下来，在GSP中，尝试将user.email更改为电子邮件。该绑定应该工作，因为电子邮件是Employer中的一个属性（通过来自用户的继承）。 – Paul 2011-06-09 11:47:53

GORM将nullable: false设置为域的每个字段的默认约束。所以当你在域中保存一行时，由于nullable:false你给uccor的错误。要解决这个问题，一种方法是将nullable:true设置为GORM的默认约束。当u需要设置nullable:true任何场u将手动设置的域类可以设置这个在您的Config.groovy

 
grails.gorm.default.constraints = { 
    '*'(nullable:true, blank:true) 
}
