Requirement is to write a controller to handle POST requests from the below urls:
http://hostname:port/com/prod1?id=2&action=add
http://hostname:port/com/prod1?id=2&action=minus
http://hostname:port/com/prod2?id=2&action=add
http://hostname:port/com/prod2?id=2&action=minus
Can I have two methods, one for mapping urls with action=add, and another for urls with action=minus? All the requests are POST.
A couple years between question and answer, but yes it is possible to route based on query parameters with Spring MVC:
@RequestMapping(path = "/com/{product}", params = "add")
String add(@PathVariable("product") String product) {
System.out.println("add method; product=" + product);
return "add";
}
@RequestMapping(path = "/com/{product}", params = "minus")
String minus(@PathVariable("product") String product) {
System.out.println("minus method; product=" + product);
return "minus";
}
No to my knowledge. According to your url end points,
they are,
For these you can have 2 controller methods for each of these.
EDIT:
If I understand you correctly,
Instead of having the above end points, write 2 controller methods for request mappings,
If you want to have it in a more granular manner, then
write request mapping methods for the above.
Then you have,
http://hostname:port/com/prod1/add?id=2 http://hostname:port/com/prod1/minus?id=2
http://hostname:port/com/prod2/add?id=2 http://hostname:port/com/prod2/munus?id=2
Or you can use another approach. which is, Just use the generic end points and depending on your request parameters, redirect to different request mappings such as,
You cannot have two @RequestMapping methods to map to two URLs differing only by query parameters. The @RequestMapping only binds to the path portion of the URL.
You can have two methods if you dispatch on the action value, calling one method for add and another for minus.
Or, you can make add or minus a part of the URL path.
It is possible with the following code:
@GetMapping(path = "/com/{product}", params = "action=add")
public String add(@PathVariable("product") String product) {
System.out.println("add method; product=" + product);
return "add";
}
@GetMapping(path = "/com/{product}", params = "action=minus")
public String minus(@PathVariable("product") String product) {
System.out.println("minus method; product=" + product);
return "minus";
}
