如何通過一些自定義消息檢票覆蓋FileUpload的uploadTooLarge消息

Question

我有一個包含可重用面板的頁面。該面板包含文件上傳邏輯。我已經將form.setMaxSize（）設置爲10MB。是否可以重寫默認的Wicket消息並顯示一些自定義消息？

Answer 1

看一看Form.onFileUploadException：

if (e instanceof SizeLimitExceededException) 
{ 
    // Resource key should be <form-id>.uploadTooLarge to 
    // override default message 
    final String defaultValue = "Upload must be less than " + getMaxSize(); 
    String msg = getString(getId() + '.' + UPLOAD_TOO_LARGE_RESOURCE_KEY, Model.ofMap(model), defaultValue); 
    error(msg); 
}
