模拟resttemplate

Question

 ResponseEntity<List<AgreementRecord>> myEntity = new 
 ResponseEntity<List<AgreementRecord>>(HttpStatus.ACCEPTED);

    when(restTemplate.exchange(
             ArgumentMatchers.anyString(),
             ArgumentMatchers.any(HttpMethod.class),
             ArgumentMatchers.<HttpEntity<?>>any(),
             ArgumentMatchers.<Class<?>>any())).thenReturn(myEntity);

其余模板从应用程序返回列表Eclipse抛出编译错误

类型为OngoingStubbing>的thenReturn（ResponseEntity）方法不适用于参数（ResponseEntity>）

休息模板

      ResponseEntity<List<AgreementRecord>> responseEntity = 
      restTemplate.exchange(smoUrl+ GET_AGREEMENT_RECORDS + customerId 
      ,HttpMethod.GET,null,new 
      ParameterizedTypeReference<List<AgreementRecord>>() {
       });
      responseEntity.getBody();

Answer 1

您可以做的一件事就是通过doReturn（）避开Mockito的编译时类型检查。

doReturn(myEntity)
    .when(restTemplate)
    .exchange(
        ArgumentMatchers.anyString(),
        ArgumentMatchers.any(HttpMethod.class)
        ArgumentMatchers.<HttpEntity<?>>any(),
        ArgumentMatchers.<Class<?>>any()));

这将返回myEntity而不进行编译时类型检查。 如果您输入的类型错误，则会在运行测试后立即找出。

编辑：

@Test()
public void test() {
    class AgreementRecord {}

    ResponseEntity<List<AgreementRecord>> myEntity = new ResponseEntity<>(
        Arrays.asList(new AgreementRecord()), HttpStatus.ACCEPTED);
    doReturn(myEntity)
        .when(restTemplate)
        .exchange(
            anyString(),
            any(HttpMethod.class),
            any(),
            any(ParameterizedTypeReference.class));

    ResponseEntity<List<AgreementRecord>> responseEntity = restTemplate.exchange(
            "url", HttpMethod.GET, null, new ParameterizedTypeReference<List<AgreementRecord>>() {});

    List<AgreementRecord> body = responseEntity.getBody();

    assertTrue(responseEntity.getStatusCode().is2xxSuccessful());
    assertNotNull(body);
}
