Mockito mocking restTemplate.postForEntity
提问by Dax Durax
I am trying to mock restTemplate.postForEntitymethod,
我正在尝试模拟restTemplate.postForEntity方法，
The actual method call is:
实际的方法调用是：
URI myUri = new URI(myString);
HttpEntity<String> myEntity ...
String myResponse = restTemplate.postForEntity(myUri, myEntity, String.class);
What I have in my test class is:
我在测试课上的内容是：
Mockito.when(restTemplate.postForEntity(any(URI.class), any(HttpEntity.class), eq(String.class))).thenReturn(response);
This does not work; I have tried several other permutations with no success either. Any suggestions appreciated, thanks.
这不起作用；我尝试了其他几种排列也没有成功。任何建议表示赞赏，谢谢。
By this does not work I mean that the actual method is called and not the mocked method (so the desired result is not returned etc.)
这不起作用我的意思是调用了实际方法而不是模拟方法（因此不会返回所需的结果等）

The following code works for me -
when(mockRestTemplate.postForEntity(anyString(), any(), eq(String.class))).thenReturn(response);
以下代码对我有用-
when(mockRestTemplate.postForEntity(anyString(), any(), eq(String.class))).thenReturn(response);

You have to make sure that you initialize the restTemplate as a mock in your tests
您必须确保在测试中将 restTemplate 初始化为模拟
RestTemplate restTemplate = mock(RestTemplate.class);
AND that this (mocked) rest template is the one being used in your actual method call. You could have a setRestTemplate() method on your object, and you could use that to set the restTemplate:
并且这个（模拟的）rest 模板是您实际方法调用中使用的模板。你可以在你的对象上有一个 setRestTemplate() 方法，你可以使用它来设置 restTemplate：
myTestObject.setRestTemplate(restTemplate);
Mocks will neverjust call the original method, so if that's happening you can be pretty sure your actual method is not using a mock. (Real) mocks will either return what you told them to, or null.
模拟永远不会只调用原始方法，因此如果发生这种情况，您可以非常确定您的实际方法没有使用模拟。（真实）模拟将返回您告诉他们的内容，或者返回空值。

I'd guess that the postForEntitymethod is final - you could use RestOperationsinstead of RestTemplateto work around that.
我猜这个postForEntity方法是最终的 - 你可以使用RestOperations而不是RestTemplate解决这个问题。

This is what worked for me Firstly a resttemplate needs to be mocked in the test class
这对我有用首先需要在测试类中模拟一个resttemplate
@Mock private RestTemplate mockRestTemplate;
Since ResponseEntity returns an Object create another method that returns the expected response wrapped in ResponseEntity
由于 ResponseEntity 返回一个 Object 创建另一个方法，该方法返回包装在 ResponseEntity 中的预期响应
private ResponseEntity<Object> generateResponseEntityObject(String response, HttpStatus httpStatus){
return new ResponseEntity<>(response, httpStatus);
}
In your test case, you can now mock the expected response as follows
在您的测试用例中，您现在可以模拟预期的响应如下
String string = "result";
when(mockRestTemplate.postForEntity(anyString(), any(), any()))
.thenReturn(generateResponseEntityObject(string, HttpStatus.OK));

resttemplate returns ResponseEntity
resttemplate 返回 ResponseEntity
Postforentityso something like ResponseEntitymyResponse= restTemplate.postForEntity(myUri, myEntity, StringToReturn.class); where StringToReturn is whatever type to return (just String in your case)
Postforentity类似于 ResponseEntitymyResponse=restTemplate.postForEntity(myUri, myEntity, StringToReturn.class); 其中 StringToReturn 是要返回的任何类型（在您的情况下只是 String ）
