Rest Client gives Bad Request for HTTP PUT request - rest

Question

I'm new to Rest Client development. Need your help in figuring out how to get a proper response for below rest service.
curl --location --request PUT 'sandbox-url/TokenGeneratorAPI/v1/update_pay_status' \
--header 'Content-Type: application/json' \
--header 'Authorization: Basic {{token}' \
--data-raw '{
"pay_id":000000000,
"status":1,
"amount":0.00,
"pay_method":0,
"pay_sys_ref":"test"
}'
I created a class in client side for request object like below.
public class PaymentRqBean {
#XmlElement(name="pay_id")
String pay_id;
#XmlElement(name="status")
String status;
#XmlElement(name="amount")
String amount;
#XmlElement(name="pay_method")
String pay_method;
#XmlElement(name="pay_sys_ref")
String pay_sys_ref;
public String getPay_id() {
return pay_id;
}
public void setPay_id(String pay_id) {
this.pay_id = pay_id;
}
}
......and getters setters for other attributes
And created a method for calling the web service in another class like below.
public PaymentRsBean callWS(PaymentRqBean pReq) {
PaymentRsBean prs = new PaymentRsBean();
Client client = ClientBuilder.newClient();
client.register(new Authenticator(com.boc.conf.Configurations.objProperty.getProperty("ikUserName"), com.boc.conf.Configurations.objProperty.getProperty("ikPassword")));
WebTarget webTarget = client.target(url);
Invocation.Builder invocationBuilder = webTarget.request(MediaType.APPLICATION_JSON);
Response response = invocationBuilder.accept(MediaType.APPLICATION_JSON).put(Entity.json(pReq));
I'm getting HTTP 400 BAD REQUEST for above. I would be so thankful for any help given in solving this.
(Is it because #XmlRootElement? )

Answer 1

The problem is the way you are defining the attributes of your PaymentRqBean class.
The variables 'pay_id', 'status', 'amount' and 'pay_method' must be of numeric type (int, double...), since the request you launch indicates that they are numeric, not Strings.
"pay_id":000000000,
"status":1,
"amount":0.00,
"pay_method":0
