在具有多个操作的类中具有多个验证功能 [英] Having multiple validation functions in a class with multiple actions
问题描述
我想在 Struts 2 中使用 action 类中的验证函数来验证表单.
I want to validate forms in Struts 2 using validate functions in the action class.
我找到了这个例子:http://www.javatpoint.com/struts-2-custom-validation-workflow-interceptor
但是,我想在同一个类中有多个功能(操作).我想对这些功能中的每一个都有一个验证功能.我们该怎么做?
However, I want to have multiple functions (actions) in the same class. And I want to have a validation function for each of these functions. How can we do this?
示例中的 validate()
函数会自动调用,因为它是 Validateable
接口函数之一.如果我有其他名称的验证函数,它们将不会被调用
The validate()
function in the example gets invoked automatically since it is one of the Validateable
interface functions. If I have validate functions with other names they won't be invoked
推荐答案
创建 validateXxx
方法,其中 Xxx
是相关操作方法的名称.
Create validateXxx
methods where Xxx
is the name of the related action method.
(这是否是最佳选择取决于您需要的特定验证.)
(Whether or not this is the best option depends on the particular validations you need.)
