Jetty Component

The jetty: component provides HTTP based endpoints for consuming HTTP requests that arrive at an http endpoint.

URI format

jetty:http:hostname[:port][/resourceUri][?options]


Options





 Name 
 Description 
 Example 
 Required? 
 default value 




 sessionSupport 
 The option for enable the session manager in the server side of Jetty. 
 sessionSupport=true 
 No 
 false 






Usage



You can only consume from endpoints generated by the Jetty component. Therefore it should only be used as input into your camel Routes. To issue HTTP requests against other HTTP endpoints you can use the HTTP Component



Sample


In this sample we define a route where we expose a http service at http://localhost:8080/myapp/myservice:




from("jetty:http://localhost:8080/myapp/myservice").process(new MyBookService());





Our business logic is implemented in our MyBookService class where we can access the http request stuff and return a response.

Note: The assert is because the code is part of an unit test.




public class MyBookService implements Processor {
    public void process(Exchange exchange) throws Exception {
        // just get the body as a string
        String body = exchange.getIn().getBody(String.class);

        // we have access to the HttpServletRequest here and we can grab it if we need it
        HttpServletRequest req = exchange.getIn().getBody(HttpServletRequest.class);
        assertNotNull(req);

        // for unit testing
        assertEquals("bookid=123", body);

        // send a html response
        exchange.getOut(true).setBody("<html><body>Book 123 is Camel in Action</body></html>");
    }
}
