Spring Boot如何测试控制器响应

Question

I try to test the response of the controller. I wrote simple test

String expectedResponse = "{price:type correct price}";

final String baseUrl = "http://localhost:"+randomServerPort+"/api/products/1";
URI uri = new URI(baseUrl);

ProductModel productModel = new ProductModel();
productModel.setPrice(-1.0);
productModel.setName("Logitech G-403");

HttpEntity<ProductModel> request = new HttpEntity<>(productModel);
ResponseEntity<String> result = this.restTemplate.postForEntity(uri, request, String.class);

assertEquals(400, result.getStatusCodeValue());
assertEquals(expectedResponse,result.getBody());

Test result:

org.opentest4j.AssertionFailedError: 
Expected :{price:type correct price}
Actual   :{"price":"type correct price"}

My question is how to test if the response returned by the controller is correct? I tried to do it on the map and on the String (shown above) but neither of them works properly

You should use Spring's MockMvc for making requests against your web layer. You can refer to this getting started guide by Spring .
