Spring - is possible to give same url in request mapping of post method?

问题

Is that possible to use same url in request mapping for two different post method, only request body differs.

回答1:

No, you can't give same url in request mapping of post method having different request body type but same media type. Below won't work:

  @PostMapping(path = "/hello", consumes = MediaType.APPLICATION_JSON_VALUE)
  public String hello(@RequestBody Pojo1 val) {
    return "Hello";
  }

  @PostMapping(path = "/hello", consumes = MediaType.APPLICATION_JSON_VALUE)
  public String hello(@RequestBody Pojo2 val) {
    return "Hello";
  }

If you have different media type, then it will. Below will work:

  @PostMapping(path = "/hello", consumes = MediaType.APPLICATION_JSON_VALUE)
  public String hello(@RequestBody Pojo val) {
    return "Hello";
  }

  @PostMapping(path = "/hello", consumes = MediaType.TEXT_PLAIN_VALUE)
  public String hello(@RequestBody String val) {
    return "Hello";
  }

Your RequestMapping should differ on at least one of the conditions; path,method,params,headers,consumes,produces

回答2:

Yes you can do that but you need to specify unique parameters signature in RequestMapping annotation:

public class MyController {

@RequestMapping(method = RequestMethod.POST, params = {"!name", "!name2"})
public String action(HttpServletRequest request, HttpServletResponse response){
    // body
}

@RequestMapping(method = RequestMethod.POST, params = "name")
public String action(HttpServletRequest request, HttpServletResponse response,
                        @RequestParam(value = "name", required = true) String name) {
    // body
}

}
