How to use Spring method DELETE

Question

I have some customers in ArrayList and when I want through Postman delete (with id) it is not working : 500 - Internal Error. Please Could someone help me ?

Delete customer
DELETE http://localhost:8080/api/customers/{customerId}

@DeleteMapping("/api/customers{customerId}") public void deleteCustomer(@PathVariable Long customerId) { customers.remove(this.customers.get(Math.toIntExact(customerId))); }

The answers thus far suggest that the culprit is your path (missing the slash after customers). This is definitely an issue, but this would not cause a 500, internal server error. Share the contents of the error, only then can this question be answered...and yes, you will have to fix that path too. — lane.maxwell

try like this you did not add "/" in delete mapping.

@DeleteMapping("/api/customers/{customerId}") public void deleteCustomer(@PathVariable Long customerId) { customers.remove(this.customers.get(Math.toIntExact(customerId))); }

Is this how you send the request?

http://localhost:8080/api/customers/{customerId}

If you are sending like this, it won't work because you gave path like this:

/api/customers{customerId}

In my opinion, either change the path like this:

/api/customers/{customerId}

Or send the request like this:

http://localhost:8080/api/customers{customerId}
