Grails - grails.converters.JSON - 删除类名 [英] Grails - grails.converters.JSON - removing the class name

问题描述

有没有办法删除 JSON 转换器中的类字段?

Is there a way to remove the class field in a JSON converter?

示例:

import testproject.*
import grails.converters.*  
emp = new Employee()  
emp.lastName = "Bar"  
emp as JSON  

作为一个字符串是

{"class":"testproject.Employee","id":null,"lastName":"Bar"}

我更喜欢

{"id":null,"lastName":"Bar"}

有没有办法在最后多加一行代码去掉class字段?

Is there a way to add one more line of code at the end to remove the class field?

推荐答案

这里还有一种方法可以做到.我在域类中添加了下一个代码:

Here is yet one way to do it. I've added a next code to the domain class:

static {
    grails.converters.JSON.registerObjectMarshaller(Employee) {
    return it.properties.findAll {k,v -> k != 'class'}
    }
}

但正如我发现的那样，如果您使用 Groovy @ToString 类注释时还必须添加 'class' 以排除参数，例如:

But as I found if you have used Groovy @ToString class annotation when you also must add 'class' to excludes parameter, e.g.:

@ToString(includeNames = true, includeFields = true, excludes = "metaClass,class")
