我如何覆盖Grails中的默认错误消息？
问题描述：
我有一个带有姓氏字段的Person对象。 lastName字段不能为空。当用户在lastName字段中提交表单空白值时，用户看到的错误消息是：
I have a Person object with a lastName field. The lastName field cannot be blank. When the user submits a form blank value in the lastName field, the error message that the user sees is:
Property [lastName] of class [com.example.Person] cannot be blank
这个错误信息是蹩脚的。我想将它定制为更加用户友好的内容，比如姓氏字段不能为空
This error message is lame. I want to customize it to something more user friendly, like "The Last Name field cannot be blank"
我该怎么做？
答
请参阅文档的第7章： http： //grails.org/doc/latest/
See Chapter 7 of the docs: http://grails.org/doc/latest/
您可以更改 grails-app / i18n / messages.properties 并添加
You would change grails-app/i18n/messages.properties and add
person.lastName.blank=The Last Name field cannot be blank
