Question

我有一个带有以下签名的端点

@RequestMapping(method = RequestMethod.GET, value = "/{id}", produces = {"application/json; charset=UTF-8"})
@Transactional(readOnly = true)
@ResponseBody
public HashMap<String, Object> myMethod(@PathVariable("id") Long id) {...}`

我想和RestTemplate打电话进行单元测试。我怎么能这样做，因为在方法getForObject中我不能将集合作为responseType。

任何想法？

Answer 1

如果映射包含的对象不是简单的字符串或数字类，则getForEntity和getForObject方法可能无法使用未类型化的Map.class作为类型来正确反序列化映射的对象。在这种情况下，请按How to get a generic map as a response from restTemplate exchange method?中所述使用ParameterizedTypeReference。

以下是一些似乎都有效的方法......

@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.DEFINED_PORT)
public class MyTests {

    @LocalServerPort private int port;
    @Autowired private TestRestTemplate restTemplate;

    @Test
    public void healthCheck() {
        String url = "http://localhost:" + port + "/actuator/health";

    //  choose one of the following...
        ResponseEntity<JsonNode> e = restTemplate.getForEntity(url,JsonNode.class);
        Map<String,Object> b = restTemplate.getForObject(url,Map.class);
        Map b = restTemplate.getForObject(url,Map.class);
        ResponseEntity<Map> e = restTemplate.getForEntity(url,Map.class);

        System.out.println("entity: "+e);
        System.out.println("body: "+b);
    }
}

调用一个返回带RestTemplate的HashMap的端点
