Is there a simple method to refresh a JSP or Spring MVC page using AJAX?

I'm tackling a seemingly basic question in Java web development here, but I could use some guidance.

How can I refresh data on a JSP page? I understand the fundamentals (utilize jQuery for AJAX, Spring MVC for the "Controller" & handle data requests). However, my stumbling block is figuring out the simplest way to display the updated data on the page (considering that JSP is all server-side and not conducive to client-side updates).

I've explored a few options:

  • Using Mozilla Rhino + Velocity in JavaScript - seems like a laborious process.

  • Trying out the "new" Spring AJAX MVC enhancements - the examples are a bit confusing for me.

  • Returning a partially rendered String in the Spring Controller's get method via business logic+Velocity - uncertain if this is the appropriate approach, as it feels somewhat messy to construct the view object within the Controller class.

Is there a straightforward solution to my query? Essentially, I need to refill an HTML table at regular intervals. I must be overlooking something crucial here.

Thanks in advance!

Answer №1

If you're looking to constantly update a specific section of your webpage, I would suggest creating a designated div for that content. You can set intervals for the div to reload with new information fetched from the server. One approach is to have the server generate the HTML and use jQuery('').load() to pull it in. Alternatively, you could retrieve JSON data from the server and dynamically create the markup, although this method may pose challenges with large datasets. I hope this advice proves useful.

Answer №2

When it comes to generating JSON or a partial view in the controller, there are multiple valid options. Personally, I lean towards using JSON when dealing with simple HTML modifications, and opt for returning an HTML fragment when refreshing a large table or loading a complex panel. Typically, to generate JSON, I prefer utilizing a Spring MVC controller method that returns a bean annotated with @ResponseBody.
