如何在Spring中将具有相同前缀uri的映射重载到不同的方法？

Question

I'm trying to map two different URI with the same prefix to two different handlers

POST "resource" -> resourcesBl.create

POST "resource/{path_variable}" -> resourcesBl.createOther

note - the request body for each one is different

and Spring doesn't do it automatically

@RestController
@RequestMapping("resource") 
public class MyController {

    @Autowired
    private ResourcesBl resourcesBl;

    @PostMapping
    public Resource create(@RequestBody Resource resource) {
        return resourcesBl.create(resource);
    }

    @PostMapping("/{resourceName}"}
    public OtherResource create(@PathVariable String resourceName, @RequestBody OtherResource otherResource, ) {
        return resourcesBl.createOther(otherResource);
    }

}

I have tried this solution with Postman, it works perfectly fine and takes the path variable, both mappings can be called with different bodies.

@RestController
@RequestMapping("/resource")
public class MyController {

    @Autowired
    private ResourcesBl resourcesBl;

    @RequestMapping(method = RequestMethod.POST)
    @ResponseBody
    public Resource create(@RequestBody Resource resource) {
        return resourcesBl.create(resource);
    }

    @RequestMapping(value = "/{resourceName}", method = RequestMethod.POST)
    @ResponseBody
    public OtherResource create(@PathVariable String resourceName,
                                @RequestBody OtherResource otherResource) {
        return resourcesBl.createOther(resourceName, otherResource);
    }
}

All requests with empty path params will be mapped to the first method, so both: "/resource" and "/resource/". Anything after the slash to the second.

Note: don't forget to use the path variable.
