Getting 404 Not Found when trying to do a GET method request in PostMan (RestController)

[Nathan Milota]

I am not sure why, but when I type in http://localhost:8080/schools, it is getting a response from the server that the local host is running, but I set up the RestController and set the value to "schools", it won't find anything.

It is almost identical to another program I made which it works fine, but for some reason, it will not find it on here, and I was wondering if there is an error in the class that might make this happen.

I have all the same dependencies that I had in another program that works, so I don't know what it is about this.

@RestController
@RequestMapping
public class SchoolController {
	
	@Autowired
	private SchoolService schoolService;
	
	@RequestMapping("/schools")
	public List<School> getAllSchools(){
		return schoolService.getAllSchools();
	}
	@GetMapping("/schools/{id}")
	public School getSchool(@PathVariable int id) {
		return schoolService.getSchool(id);
	}
	
	@PostMapping("/schools")
	public void addSchool(@RequestBody School school) {
		schoolService.addSchool(school);
		}
	@DeleteMapping("/schools/{id}")
	public void deleteSchool(@PathVariable int id) {
		schoolService.deleteSchool(id);
	}
	@PutMapping("/schools{id}")
	public void updateSchool(@RequestBody School school, @PathVariable int id) {
		schoolService.updateSchool(id, school);
	}

}

Change the @RequestMapping on getAllSchools to @GetMapping. @RequestMapping by default has no method specified, so it won't listen to any request.

For some reason, that still didn't work.  

I don't know if that's it, as I never used GetMapping on the other classes that are almost identical to this one, and those work fine.  Something else is wrong as I tried a test class, and it still isn't working right.  

@RestController
public class TestingController {
       
	@GetMapping("/testing")
	public String testing() {
		return " *BEEP*  This is just a test";
	}
}

It's returning an error saying it couldn't find a route, and does the same error if I type something that doesn't exist at all.

I wouldn't be so sure about that. I found regarding that this:

@RequestMapping – the HTTP Method
The HTTP method parameter has no default – so if we don't specify a value, it's going to map to any HTTP request.

I tried it out myself, seems to be true. So that's not a real problem.

It was a package naming error.  I think I got it figured out now.

[Nathan Milota]

The class itself was done right.  It was that I had it in a package where there was no route to it.   The package needs to have the same path mine now are

io.ticket
and
io.ticket.school


It works that way.

I guess I should check the Javadoc instead of just the source code
