I have a Spring MVC project and I have configured the jackson library to automatically transform the response (java object) to a json and it works in GET requests as following.
@RequestMapping(method = RequestMethod.GET)
public @ResponseBody Orders createOrder(Model model){
Orders orders = new Orders();
//Populate orders.....
return orders;
}
But when a I try to process the POST request and get the object from the json's request, I get the error "400 Bad Request" as Spring cannot create the object Orders from the json. I put the same json file that the GET method response, so I suppose that the file is well formatted.
@RequestMapping(method = RequestMethod.POST)
public @ResponseBody ResponseEntity<String> createOrder(@RequestBody Orders orders){
LOG.info(orders.toString());
return new ResponseEntity<String>("", HttpStatus.CREATED);
}
If I change the @RequestBody class to String (createOrder(@RequestBody String orders)), the POST request is well processed.
Do I have to create a mapper that maps the input json to the class Order?
UPDATE: I have created the most simple example to try it and I receive the error 400. Exmaple:
Domain: Home.java
public class Home {
private String address = "Calle mármoles";
public Home(){
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
}
Controller:
@RequestMapping(method = RequestMethod.POST)
public @ResponseBody ResponseEntity<String> createOrder2(@RequestBody Home orders){
return new ResponseEntity<String>("{}", HttpStatus.CREATED);
}
JSON (POST):
{
address: "Prueba"
}
[SOLVED]
I missed to put "" in the name of the parameter name.
