-
add the maven dependency
<dependency> <groupId>org.jboss.aerogear</groupId> <artifactId>aerogear-controller</artifactId> <version>1.0.0.M1</version> <scope>compile</scope> </dependency> -
create a pojo controller
public class Home { public void index() { } } -
create a Java class containing the routes (must extend
AbstractRoutingModule)public class Routes extends AbstractRoutingModule { @Override public void configuration() { route() .from("/") .on(RequestMethod.GET) .to(Home.class).index(); } } -
create a jsp page at
/WEB-INF/pages/<Controller Class Name>/<method>.jsp<!-- /WEB-INF/pages/Home/index.jsp --> <html> <body> <p>hello from index!</p> </body> </html>
You can use immutable beans straight away as controller parameters:
public class Store {
public Car save(Car car) {
return car;
}
}
This can be populated by putting a route to it (preferrably via post, of course)
route()
.from("/cars")
.on(RequestMethod.POST)
.to(Store.class).save(param(Car.class));
And you can use a simple html form for it, by just following the convention:
<input type="text" name="car.color"/>
<input type="text" name="car.brand"/>
The car object will be automatically populated with the provided values - note that it supports deep linking, so this would work fine too:
<input type="text" name="car.brand.owner"/>
All the intermediate objects are created automatically.
You can configure a route as an error handler for a type of exception:
route()
.on(YourException.class)
.to(ExceptionHandler.class).errorPage();
You can specify multiple exceptions if needed:
route()
.on(YourException.class, SomeOtherException.class)
.to(ExceptionHandler.class).errorPage();
If you'd like to log the exception in the error route, you can specify that the target method, errorPage() above, should take a parameter:
route()
.on(YourException.class, SomeOtherException.class)
.to(ExceptionHandler.class).errorPage(param(Exception.class));
As mentioned previously in this document a view for ExceptionHandler would in this case be located in:
/WEB-INF/pages/ExceptionHandler/errorPage.jsp
The exception is made available to the jsp page:
${requestScope['org.jboss.aerogear.controller.exception']}
CORS is supported by default but can be disabled or configured differently by implementing a CDI Producer:
@Produces
public CorsConfiguration demoConfig() {
return CorsConfig.enableCorsSupport()
.anyOrigin()
.enableCookies()
.exposeHeaders("header1")
.maxAge(20)
.enableAllRequestMethods()
.validRequestHeaders("header1");
}
To disable CORS support
@Produces
public CorsConfiguration demoConfig() {
return CorsConfig.disableCorsSupport();
}
