| <h1 id="redirect-action-result">Redirect Action Result</h1> |
| |
| <p>This result uses the <code class="highlighter-rouge">ActionMapper</code> provided by the <code class="highlighter-rouge">ActionMapperFactory</code> to redirect the browser to a URL that invokes |
| the specified action and (optional) namespace. This is better than the <code class="highlighter-rouge">ServletRedirectResult</code> because it does not require |
| you to encode the URL patterns processed by the <code class="highlighter-rouge">ActionMapper</code> in to your struts.xml configuration files. This means |
| you can change your URL patterns at any point and your application will still work. It is strongly recommended that if you |
| are redirecting to another action, you use this result rather than the standard redirect result.</p> |
| |
| <p>See examples below for an example of how request parameters could be passed in.</p> |
| |
| <p>See <a href="action-mapper.html">ActionMapper</a> for more details</p> |
| |
| <h2 id="parameters">Parameters</h2> |
| |
| <ul> |
| <li><code class="highlighter-rouge">actionName</code> (default) - The name of the action that will be redirected to.</li> |
| <li><code class="highlighter-rouge">namespace</code> - Used to determine which namespace the action is in that we’re redirecting to. If namespace is null, |
| the default will be the current namespace.</li> |
| <li><code class="highlighter-rouge">suppressEmptyParameters</code> - Optional boolean (defaults to false) that can prevent parameters with no values from being |
| included in the redirect URL.</li> |
| <li><code class="highlighter-rouge">parse</code> - Boolean, true by default. If set to false, the actionName param will not be parsed for OGNL expressions.</li> |
| <li><code class="highlighter-rouge">anchor</code> - Optional. Also known as “fragment” or colloquially as “hash”. You can specify an anchor for a result.</li> |
| </ul> |
