Class WicketMessageResolver
java.lang.Object
org.apache.wicket.markup.resolver.WicketMessageResolver
- All Implemented Interfaces:
- Serializable, IClusterable, IComponentResolver
public class WicketMessageResolver
- extends Object
- implements IComponentResolver
This is a tag resolver which handles <wicket:message key="myKey">Default
Text</wicket:message>. The resolver will replace the whole tag with the message found in
the properties file associated with the Page. If no message is found, the default body text will
remain.
You can also nest child components inside a wicket:message and then reference them from the
properties file. For example in the html
<wicket:message key="myKey">
This text will be replaced with text from the properties file.
<span wicket:id="amount">[amount]</span>.
<a wicket:id="link">
<wicket:message key="linkText"/>
</a>
</wicket:message>
Then in the properties file have a variable with a name that matches the wicket:id for each child
component. The variables can be in any order, they do NOT have to match the order in the HTML
file.
myKey=Your balance is ${amount}. Click ${link} to view the details.
linkText=here
And in the java
add(new Label("amount", new Model<String>("$5.00")));
add(new BookmarkablePageLink<Void>("link", DetailsPage.class));
This will output
Your balance is $5.00. Click <a href="#">here</a> to view the details.
If variables are not found via child component, the search will continue with the parents
container model object and if still not found with the parent container itself.
It is possible to switch between logging a warning and throwing an exception if either the
property key/value or any of the variables can not be found.
