String urlFetchCustomers="http://localhost:8080/fetch/customers";

JsonNode customerJSON = mapper.readTree("{"result":["User1","User2","User3"],"message":"Fetched customers successfully.","status":200}");

ResponseEntity<JsonNode> customerResponse = new ResponseEntity<JsonNode>(customerJSON, HttpStatus.OK);

ResponseEntity<JsonNode> placeResponse = new ResponseEntity<JsonNode>(placeJSON, HttpStatus.OK);

when(restTemplate.exchange(urlFetchCustomers, 
                       Matchers.any(HttpMethod.class),
                       Matchers.<HttpEntity<?>> any(), 
                       Matchers.<Class<String>> any()
                      )
                     ).thenReturn(customerResponse);

when(restTemplate.exchange(urlFetchPlaces, 
                       Matchers.any(HttpMethod.class),
                       Matchers.<HttpEntity<?>> any(), 
                       Matchers.<Class<String>> any()
                      )
                     ).thenReturn(placeResponse);

我想对不同的url使用不同的exchange调用并返回相应的响应。但这会引发以下错误。。有人能帮忙吗？在此处输入图像描述
