Question

我试图模拟这个使用rest模板调用API并返回List的服务。

我无法模仿restTemplate.exchange()方法。它给了我一个“java.lang.IllegalArgumentException：URI不是绝对的”异常。

编辑 - 我的愚蠢的自我忘了把http：//放在测试用例的基本网址之前，这就是我得到它的原因。感谢您为浪费时间提供帮助和道歉。

待测方法

@Value("${base-url}")
private String baseUrl;

@Override
public List<Currency> getCurrencyList() {
    RestTemplate restTemplate = new RestTemplate();
    String url = baseUrl + "/currency";
    ResponseEntity<List<Currency>> result;
    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.APPLICATION_JSON);
    HttpEntity<String> dataHttpEntity = new HttpEntity<>(headers);
    log.info(url);
    result = restTemplate.exchange(url, HttpMethod.GET,dataHttpEntity, new ParameterizedTypeReference<List<Currency>>() {
    });
    return result.getBody();
}

测试代码

@Test
public void getCurrencyListTest() {
   ResponseEntity<List<Currency>> result = ResponseEntity.ok(currencyList);

    when(restTemplate.exchange( ArgumentMatchers.anyString(),
            ArgumentMatchers.any(HttpMethod.class),
            ArgumentMatchers.any(),
            ArgumentMatchers.<Class<List<Currency>>>any())).thenReturn(result);
     assertEquals(currencyList,service.getCurrencyList());
}

例外

Answer 1

为你的baseUrl提供一个协议名称，请再试一次，我的意思是协议是：http或https。

例如：

String url = "http://" + baseUrl + "/currency";

Answer 2

根据例外，由于ArgumentMatcher.anString（），URL无效。你应该提供绝对网址。

模拟RestTemplate.exchange（）给出URI不是绝对异常
