This tutorial will focus on implementing a Redirect in Springand will discuss the reasoning behind each strategy.
Let’s first consider the reasons why we may need to do a redirectin a Spring application. There are many possible examples and reasons of course. For example, we might need to POST form data, work around the double submission problem or just delegate the execution flow to another controller method. A quick side note here: The typical Post/Redirect/...
Let’s start with this simple approach and go straight to an example: Behind the scenes, RedirectView will trigger an HttpServletResponse.sendRedirect(), which will perform the actual redirect. Notice here how we’re injecting the redirect attributes into the method.The framework will do the heavy lifting and allow us to interact with these attribute...
The previous approach — using RedirectView— is suboptimal for a few reasons. First, we’re now coupled to the Spring API because we’re using the RedirectViewdirectly in our code. Second, we now need to know from the start, when implementing that controller operation, that the result will always be a redirect, which may not always be the case. A bett...
Let’s now see how to do something slightly different: a forward. Before the code, let’s go over a quick, high-level overview of the semantics of forward vs redirect: 1. redirect will respond with a 302 and the new URL in the Locationheader; the browser/client will then make another request to the new URL. 2. forwardhappens entirely on a server side...
Next, let’s look closer at passing attributes in a redirect, making full use of the framework with RedirectAttributes: As we saw before, we can inject the attributes object in the method directly, which makes this mechanism very easy to use. Notice also that we are adding a flash attribute as well.This is an attribute that won’t make it into the UR...
Let’s now explore an alternative configuration: a redirect without using the prefix. To achieve this, we need to use an org.springframework.web.servlet.view.XmlViewResolver: This is instead of org.springframework.web.servlet.view.InternalResourceViewResolver we used in the previous configuration: We also need to define a RedirectViewbean in the con...
For use cases like bank payments, we might need to redirect an HTTP POST request. Depending on the HTTP status code returned, POST request can be redirected to an HTTP GET or POST. As per HTTP 1.1 protocol reference, status codes 301 (Moved Permanently) and 302 (Found) allow the request method to be changed from POST to GET. The specification also ...
Now let’s consider a scenario where we would want to send some parameters across to another RequestMapping with a forwardprefix. In that case, we can use an HttpServletRequestto pass in parameters between calls. Here’s a method forwardWithParams that needs to send param1 and param2 to another mapping forwardedWithParams: In fact, the mapping forwar...
This article illustrated three different approaches to implementing a redirect in Spring, how to handle/pass attributes when doing these redirects and how to handle redirects of HTTP POST requests. As always, all of these examples are available on GitHub.
Create a new RedirectView with the given URL and an alternate redirect status code such as HttpStatus.TEMPORARY_REDIRECT or HttpStatus.PERMANENT_REDIRECT.
31 lug 2013 · You can use the RedirectView. Copied from the JavaDoc: View that redirects to an absolute, context relative, or current request relative URL. Example: @RequestMapping("/to-be-redirected") public RedirectView localRedirect() { RedirectView redirectView = new RedirectView(); redirectView.setUrl("http://www.yahoo.com"); return ...
20 feb 2017 · Spring MVC - Redirecting using RedirectView. Unlike URL forward (which is entirely server internal redirect), URL redirect sends the redirect HTTP code (typically 302) to the client browser along with new 'Location' header. The Browser re-submits the new 'Location' URL to the server.
28 giu 2019 · How to Use Spring MVC RedirectView. org.springframework.web.servlet.view.RedirectView redirects URL that can be absolute or relative to context. It can also be used as URI template and the values of template will automatically be replaced by the same key in the Model or attributes in RedirectAttributes.
29 apr 2020 · A common case in Java web application development with Spring MVC is redirecting the users to a specific URL after an operation has completed. For example, when the user clicks Save button on a form to create a new item, he will be redirected to the items list page.
