Struts2 - 禁用转换错误

发布于 2024-11-08 21:01:01 字数 328 浏览 2 评论 0原文

我有一个 ssn 字段（在 Action 类中表示为 String），用户在其中输入以下格式的内容 123-23-2233。 Struts2 抛出错误。我不知道它在哪里配置为将其作为错误抛出。我该如何阻止这个？

我在 validate() 方法中有自己的验证，如下所示

if(StringUtility.isBlank(person.getSsn()) || !validateRegex(SSN_REGEX,person.getSsn().trim())){
   this.addFieldError("person.ssn","SSN is required");
}

I have a ssn field (represented as a String in Action class) in which the user enters something in the following format 123-23-2233. Struts2 throws an error. I dont know where it is configured for it to throw this as an error. How do I stop this?

I have my own validation in the validate() method, something like this

if(StringUtility.isBlank(person.getSsn()) || !validateRegex(SSN_REGEX,person.getSsn().trim())){
   this.addFieldError("person.ssn","SSN is required");
}

在验证方法运行之前，转换错误将被添加到字段错误映射中。因此，一旦您进入验证方法，就有一种非常简单的方法可以删除它们。只需从地图中删除错误，然后再添加自己的错误即可。

下面的示例代码；

if(yourCondition){
   // Check whether this field has existing errors and remove them.
   List<String> existingErrors = getFieldErrors().get("person.ssn");
   if(existingErrors != null){
       existingErrors.clear();
   }       
   // Add your own error.
   addFieldError("person.ssn","SSN is required");
}

同样，如果您想清除所有字段上的默认错误消息，您可以清除整个字段错误映射。

我希望这有帮助。

The conversion errors will be added to the field errors map before your validate method even runs. As such there is a very simple way of removing them once you get to your validate method. Simply remove the error from the map before adding your own.

Example code below;

if(yourCondition){
   // Check whether this field has existing errors and remove them.
   List<String> existingErrors = getFieldErrors().get("person.ssn");
   if(existingErrors != null){
       existingErrors.clear();
   }       
   // Add your own error.
   addFieldError("person.ssn","SSN is required");
}

Similarly you could clear the entire field errors map if you wanted to clear the default error messages on all fields.

I hope this helps.
