I am working on Struts 1.1 to Spring 4 mvc migration project. In struts code action errors are getting displayed in JSP using the action messages are getting from applicationresources.properties file. This property file has errors.header and errors.footer which will be added for every error message. What is the equivalent solution in spring mvc to add header and footer for errors.

Having added the error.html Thymeleaf template to replace the default error page on Spring how can I get access to the exception on that page?
So I have custom exception thrown on some controller. How to access that exception on the Thymeleaf page?
I want this to work globally, so any controller thrown exception should be accessible.
Case 1: For customized error pages with spring default error info
There are some predefined objects in Thymeleaf to show error information, e.g. ${error}, ${exception} and so on. These objects can be used in your customized error page.
This article will help you more. Custom Error Page with Thymeleaf
Case 2: For customized error pages with customized error info
There are #ControllerAdvice and #ExceptionHandler used to handle exceptions in controllers globally. A certain exception can be add to Modal's attribute and therefore accessed in thymeleaf templates. However, please be noted that the solution does not work in Webflux.
The blog shows details about the solution. Exception Handling in Spring MVC
I'm using Spring Boot with Vaadin and. By using the #Autowired SpringNavigator, I have also set the error view:
navigator.setErrorView(ErrorView.class);
But when I type wrong URL like http://localhost:8080/asdf .
I always get the Spring Boot's Whitelabel error page. I know that I can set custom HTML page for the error like
/resources/public/error/404.html
but this is HTML way, I would like to use Vaadin with components,
the best solution would be the mentioned error view.
I have spring webflow applicaiton, which has a contact info page and while submitting the form, it goes to spring validator.
And executing validations, if any wrong data then we adding a error message to validationcontext. Using ${errorMessags} we list the error messages.
But I have a scenario where I need to show a warning message to user in middle of page.
Either through spring validation or spring flowscope variable in Spring Validator
Is there any way to do it?
Thanks in Advance!!!
Why do you want to do that on validator? Do you want to show that warning in next view?
I guess you could set message in or in to flashScope variable and show it on next page.
Can we display error messages in one jsp but in 2 different forms.I am validating my bean using spring validation.Its working fine but if there is an error in the binding results then I am able to display the error message in the form from where action is executed but not in the other resultant form.
is the error tag in spring validation is mapped to jsp form from where that action is called.
Your BindingResults is just an object, which you can put in your Model and use on the page however you want. You may need to put it into Session if you plan to use it on a separate form.
I'm new in spring roo. I want to create a page with file upload. I used spring roo to create all pages and i try to use it to create a file browser button in file upload page. The problem is spring roo using spring form tag which doesn't have file browser. I solve this problem by using html input type="file" tag instead, but the spring roo showed the error like this "Failed to invoke handler method [public void egat.spring.roo.ptu.io.web.ImportExcelController.post(java.lang.Long,org.springframework.ui.ModelMap,javax.servlet.http.HttpServletRequest,javax.servlet.http.HttpServletResponse)]; nested exception is java.lang.IllegalStateException: Could not find #PathVariable [id] in #RequestMapping "
How can i solve this problem?
