Easy Spring problem!

[Richard Carrot]

I'm new to spring and was wondering whether someone could help me figure out an easy problem which I cannot.

I have the following method in a controller which I would like to display the data from, on a .jsp. The code is from a tutorial that I've been following however the tutorial doesn't seem to be talking about how the data ends up on the .jsp. I want to display the data in a table on a .jsp which is not how it works at the moment.

@RequestMapping(value = "/rides", method = RequestMethod.GET)
public @ResponseBody List<Ride> getRides() {
		
	return rideService.getRides();
}

Are you able to provide a link to the tutorial or fully cite the name and author so that we can see the full source to put this into full/proper context?

The code snippet is from a pluralsight tutorial spring and JDBC, I think his name is Bryan Hansen.

[Pete Letkeman]

Please note, that I'm new to Spring as well, and therefore this could be incorrect.

Presumably, looking at the code the following happens:
1) A get request is made to /rides
2) The method getRides() is called which returns a list of Ride objects
3) Spring finds a template file, named rides.jsp and injects the data into that file then sends that page to the client/web browser.

Step 3 is the "magic" step. As long as you have the JSP file (View) in the correct location Spring will read that file and combine the data from the Model as specified by the Controller.

We don't really have to know how Spring finds the file, as many things are setup by convention over configuration.
There are different template engines out there which can be quickly changed out in Spring and each one handles the data slightly differently.

Yes I believe you are correct. I've been able to make some progress. I changed the controller method to this and added the following to a .jsp all seems to be working.

@RequestMapping(value="/rides", method = RequestMethod.GET)
	public String find(Model model){
		model.addAttribute("rides", this.rideService.getRides());
		return "rides";
	}

and the .jsp

<c:forEach items="${rides}" var="ride">
	<tr>
	<td>${ride.id}</td>
	<td>${ride.name}</td>
	<td>${ride.duration}</td>
	</tr>	
</c:forEach>

onto the next thing to solve

Great, I'm glad you got it working.

Hopefully it will be a smooth ride from here on out.
