Given a simple REST controller in Spring Boot...
#GetMapping("/user/{email}")
public UserResponse getUser(#PathVariable("email") String email) {
return userService.getUserByEmail(email);
}
... I created a #WebMvcTest using MockMvc to assert the JSON content of the UserResponse object. Is it possible to also assert that the JSON string matches the UserResponse class itself (similar to Java's instance of)? I found the following but this does not work:
.andExpect(jsonPath("$", typeCompatibleWith(UserREsponse.class)))
Related
#ControllerAdvice
public class CA implements ResponseBodyAdvice<Object> { }
This class will wrap the response
#GetMapping
public Person getPerson()
{
return new Person();
}
In Swagger I want it to show WrappedResponse but instead it shows response of return type here(Person).
What changes to make so that it will show the wrapped response ?
Tried different combinations of APIReponse, APIModel, APIResponses of swagger but nothing seems to work
I am writing an e2e test for my application.
I have written the following test class
#AutoConfigureMockMvc
#SpringBootTest
public class LineItemControllerIntegrationTest {
#Autowired
private MockMvc mockMvc;
#Test
void testGetLineItems() throws Exception {
mockMvc.perform(get("/service/students")
.queryParam("isArchived", "false")
.queryParam("limit", "10")
.queryParam("offset", "0"))
.andExpectAll(status().isOk(), content().contentType(MediaType.APPLICATION_JSON));
}
}
I would like to validate the response against a JSON schema because the response of this API would be dynamic. So, we can not validate it with any other JSON object.
For example, support the reponse returned by /service/students is
[
{ "Name":"Rahul","age":10}
]
Then my validation would be
response should be an array
each array item will contain a string property named "name"
each array item will container a integer property named "age"
How can i validate it using MocMvc?
Thanks in advance.
I want SpringBoot to be able to provide default values for fields that the user must enter. For example, I have something like this:
*Controller class*
#PostMapping("/test")
public ResponseEntity<> myMethod(#RequestBody #Valid MyContract contract) {}
*MyContract class*
#Valid
DataObject dataObject;
*DataObject class*
#Component
public class DataObject {
private #Value("${field1.default}") String field1Default;
private String field1
public String getField1() {
return (field1 == null ? field1Default : field1);
}
}
The DataObject class needs to be created on a per request basis. There are also other places in the code where it needs to be created on demand. So I imagine it needs to be a Prototype object. But I can't figure out how to get Spring to created it properly when it creates it for the request.
Update
I have read more about #RequstBody, e.g., https://www.javadevjournal.com/spring/spring-request-response-body/ and Should spring #RequestBody class be singleton or prototype?, which explains that the object is not a Component, but a simple POJO that gets the values from the Json request. So it seems that there is no way to inject #Values from the Spring application.properties file. Is there any other way around this? Or another suggested implementation?
Using Webflux and Reactive Spring Security, how do you do post processing via annotations to control access to methods?
Trying a very basic sample, I'm not able to get the value from the PostAuthorize annotation. For example
#GetMapping
#PostAuthorize("#email == authentication.principal.email")
public Flux<Project> sampleTest(final String email) {
log.info("email: {}", email);
return Flux.empty();
}
The email will always be null. I have the basic wiring working to the fact if I set something like #PreAuthorize("hasRole('ADMIN')") I'll get back a 403.
I can extract the Authentication out with a helper like:
public Mono<Authentication> getAuthentication() {
return ReactiveSecurityContextHolder.getContext()
.map(SecurityContext::getAuthentication)
.flatMap(Mono::just);
}
I may not be understanding your question correctly, but the PostAuthorize uses the return object - the body of the method doesn't have access to anything in the SPEL expression.
Something like this might work -
#GetMapping
#PostAuthorize("returnObject == someCondition")
public Flux<Project> sampleTest(final String email) {
// get some data and return it
}
But maybe you want to filter the items in the Flux?
You might look at the #PostFilter annotation -
// assuming there's an email property on your Project object.
#GetMapping
#PostFilter("filterObject.getEmail() == authentication.principal.email")
public Flux<Project> sampleTest() {
// get some data and return it
}
I am testing a REST API's in Spring boot gradle app, my mocked service using #MockBean is returning null. This mocked service return null if there are some beans Autowired in service class(I used constructor injection).
Here is sample Code(Not compiled, only for understanding)
#RestController
#RequestMapping("/xxx")
class TestController {
private RetriveDataService retriveDataService;
public TestControllerx(RetriveDataService retriveDataService) {
this.retriveDataService = retriveDataService;
}
#PostMapping(value = "/yyy")
public MyResponseModel myMethod(#RequestBody MyRequestModel model) {
return retriveDataService.retriveData(model);
}
}
#Service
class RetriveDataService {
private TokenService tokenService;
public RetriveDataService(TokenService tokenService) {
this.tokenService = tokenService;
}
public MyResponseModel retriveData(MyRequestModel model) {
String accessToken = tokenService.getToken().getAccessToken();
return retriveData(model, accessToken);
}
}
#RunWith(SpringRunner.class)
#WebMvcTest(TestController.class)
public class TestControllerTest {
#Autowired
private MockMvc mvc;
#Autowired
private ObjectMapper objectMapper;
#MockBean
private RetriveDataService retriveDataService;
#Test
public void testRetriveData() throws Exception {
mvc.perform(MockMvcRequestBuilders.post("/xxx/yyy").content(objectMapper.writeValueAsString(new MyRequestModel()))
.contentType(MediaType.APPLICATION_JSON_UTF8)).andDo(MockMvcResultHandlers.print())
.andExpect(content().contentType(MediaType.APPLICATION_JSON_UTF8));
}
}
When I run this test, i am getting following output(If my service do not need another bean, I am getting expected output)
MockHttpServletResponse:
Status = 200
Error message = null
Headers = []
Content type = null
Body =
Forwarded URL = null
Redirected URL = null
Cookies = []
Due to this response i facing problem on line .andExpect(content().contentType(MediaType.APPLICATION_JSON_UTF8));. also when i check response body(as body is also a null)
Sample project to reproduce the issue is here
Checking your repository confirmed assumption form the discussion in comments under question.
You specify expectations on your mock
MyModel requestMessage = new MyModel();
requestMessage.setMessage("Hello Request Post");
given(testService1.getMessage(requestMessage)).willReturn(responseMessage);
but the message received to in your controller in your #WebMvcTest is not equal to requestMessage specified in the test. This is due to the fact that MyModel class does not override equals method.
In this situation, Mockito will use its default behaviour:
By default, for all methods that return a value, a mock will return either null, a primitive/primitive wrapper value, or an empty collection, as appropriate. For example 0 for an int/Integer and false for a boolean/Boolean.
You have two options to fix the problem:
override equals (and hashCode) in your request class.
Get acquainted with argument matchers
More info on option 2.:
Technically, your expectation is equivalent to:
given(testService1.getMessage(ArgumentMatchers.eq(requestMessage)))
.willReturn(responseMessage);
You can use other matcher, or even define your own. This is useful if you cannot modify code of your argument's type (type coming from 3-rd party library etc).
For example, you can use ArgumentMatchers.any(MyModel.class))
